kn-title=Increasing visual uncertainty modulates multisensory decision-making

kn-abstract=The brain integrates and transforms information from multiple senses to make optimal decisions, a process that is critical for navigating complex environments with perceptual uncertainty. Despite a growing consensus that individuals adapt flexibly to uncertain sensory input, whether increasing visual uncertainty influences the decision process itself or other, non-decision sensory processes during multisensory decision-making are unclear. Here, an audiovisual categorization task was used to examine the responses of human participants (N = 30) to visual and audiovisual stimuli under low-, medium-, and high-uncertainty conditions. Modeling the behavioral data using a drift?diffusion model indicated that increased visual uncertainty in the audiovisual context decreased the evidence accumulation rate but had no effect on non-decision processes. Electrophysiological recordings confirmed and expanded upon these results: increased visual uncertainty in the audiovisual context reduced the amplitude during the late decision-making stage (300?380 msec) but had no effect on the amplitude during the early sensory encoding stage (140?220 msec). More importantly, electroencephalography analyses revealed that audiovisual integration in the early sensory encoding stage occurred robustly across all visual uncertainty conditions, whereas audiovisual integration in the late stage occurred only under medium and high visual uncertainty conditions. This study demonstrated that increased visual uncertainty modulates the decision process itself rather than early sensory encoding during multisensory decision-making. Moreover, multisensory integration strategies dynamically adapt to increasing visual uncertainty by engaging different mechanisms to maintain effective decision-making.

kn-title=Heart failure-specific cardiac fibroblasts contribute to cardiac dysfunction via the MYC?CXCL1?CXCR2 axis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Heart failure (HF) is a growing global health issue. While most studies focus on cardiomyocytes, here we highlight the role of cardiac fibroblasts (CFs) in HF. Single-cell RNA sequencing of mouse hearts under pressure overload identified six CF subclusters, with one specific to the HF stage. This HF-specific CF population highly expresses the transcription factor Myc. Deleting Myc in CFs improves cardiac function without reducing fibrosis. MYC directly regulates the expression of the chemokine CXCL1, which is elevated in HF-specific CFs and downregulated in Myc-deficient CFs. The CXCL1 receptor, CXCR2, is expressed in cardiomyocytes, and blocking the CXCL1?CXCR2 axis mitigates HF. CXCL1 impairs contractility in neonatal rat and human iPSC-derived cardiomyocytes. Human CFs from failing hearts also express MYC and CXCL1, unlike those from controls. These findings reveal that HF-specific CFs contribute to HF via the MYC?CXCL1?CXCR2 pathway, offering a promising therapeutic target beyond cardiomyocytes.

kn-title=Cardiotoxicity Assessment of EGFR Tyrosine Kinase Inhibitors Using Human iPS Cell‐Derived Cardiomyocytes and FDA Adverse Events Reporting System
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Recent advances in the development of anti-cancer drugs have contributed to prolonged survival of cancer patients. In contrast, drug-induced cardiotoxicity, particularly cardiac contractile dysfunction, is of growing concern in cancer treatment. Therefore, it is important to understand the risks of anti-cancer drug-induced cardiac contractile dysfunction in drug development. We have previously developed image-based motion analysis using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to assess the effect of drugs on contractility. However, the utility and predictive potential of image-based motion analysis using hiPSC-CMs for anti-cancer drug-induced cardiac contractile dysfunction have not been well understood. Here we focused on epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) and investigated the correlation between the hiPSC-CMs data and clinical signals of adverse events related to cardiac contractile dysfunction. We examined the effects of the four EGFR-TKIs, osimertinib, gefitinib, afatinib, and erlotinib, on the contractility of hiPSC-CMs using image-based motion analysis. We found that osimertinib decreased contraction velocity and deformation distance in a dose- and time-dependent manner, whereas gefitinib, afatinib, and erlotinib had little effect on these parameters. Next, we examined the real-world data of the EGFR-TKIs using FDA Adverse Event Reporting System (FAERS; JAPIC AERS). Only osimertinib showed significant clinical signals of adverse events related to cardiac contractile dysfunction. These data suggest that hiPSC-CM data correlate with clinical signals in FAERS analysis for four EGFR-TKIs. Thus, image-based motion analysis using hiPSC-CMs can be a useful platform for predicting the risk of anti-cancer drug-induced cardiac contractile dysfunction in patients.

kn-title=Neurotransmitter recognition by human vesicular monoamine transporter 2
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Human vesicular monoamine transporter 2 (VMAT2), a member of the SLC18 family, plays a crucial role in regulating neurotransmitters in the brain by facilitating their uptake and storage within vesicles, preparing them for exocytotic release. Because of its central role in neurotransmitter signalling and neuroprotection, VMAT2 is a target for neurodegenerative diseases and movement disorders, with its inhibitor being used as therapeutics. Despite the importance of VMAT2 in pharmacophysiology, the molecular basis of VMAT2-mediated neurotransmitter transport and its inhibition remains unclear. Here we show the cryo-electron microscopy structure of VMAT2 in the substrate-free state, in complex with the neurotransmitter dopamine, and in complex with the inhibitor tetrabenazine. In addition to these structural determinations, monoamine uptake assays, mutational studies, and pKa value predictions were performed to characterize the dynamic changes in VMAT2 structure. These results provide a structural basis for understanding VMAT2-mediated vesicular transport of neurotransmitters and a platform for modulation of current inhibitor design.

kn-title=Real‐World Data of Comprehensive Cancer Genomic Profiling Tests Performed in the Routine Clinical Setting in Sarcoma
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction: Next-generation sequencing-based comprehensive cancer genomic profiling (CGP) tests are beneficial for refining diagnosis and personalized treatment of various cancers. However, the clinical impact of CGP, as covered by public health insurance in the management of sarcomas, remains unknown. Especially, the data on the utility of the newly emerging dual DNA?RNA panel compared to the conventional DNA-only panel in clinical settings is lacking. Therefore, we evaluated the utility of CGP in routine clinical practice for sarcoma treatment.
Patients and Methods: In this study, three types of DNA panel and one DNA?RNA panel, reimbursed by Japanese public health insurance, were utilized. We detected oncogenic and druggable gene mutations and genotype-matched therapies.
Results: One hundred and thirty-six patients were included in this study. Based on the detection of highly histology-specific translocations in the sequencing results, 2.2% of patients were re-classified. In patients with translocation-related sarcomas, a DNA?RNA panel identified more histology-specific fusion genes than DNA panels (p?=?0.0035). Specifically, 86.8% and 39.0% of patients had oncogenic and druggable genomic alterations, respectively. Of these, 9.6% underwent genotype-matched therapy, with a 36.3% response rate and an 81.8% disease control rate. Patients who were administered genomically matched therapy had better overall survival (OS) than those who did not in patients with metastatic or advanced sarcoma with no prior chemotherapy (3-year OS: 83.3% vs. 48.0%, p?=?0.42). Patients with TP53 and RB1 mutations had worse OS than those without. Germline findings were detected in 11.0% of the patients, one of whom had a truly germline origin.
Conclusions: This study suggests that publicly reimbursed CGP tests, particularly the dual DNA?RNA panel, could be beneficial for refining diagnostic precision in selected sarcoma subtypes, treatment decisions, detecting the germline findings, and prognosis prediction in routine clinical settings for sarcoma. The implementation of genotype-matched therapies showed favorable clinical outcomes and improved the prognosis.

kn-title=Immune evasion through mitochondrial transfer in the tumour microenvironment
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T?cell attack1. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses2,3,4. However, detailed mechanisms of such processes remain unclear. Here we analyse clinical specimens and identify mitochondrial DNA (mtDNA) mutations in TILs that are shared with cancer cells. Moreover, mitochondria with mtDNA mutations from cancer cells are able to transfer to TILs. Typically, mitochondria in TILs readily undergo mitophagy through reactive oxygen species. However, mitochondria transferred from cancer cells do not undergo mitophagy, which we find is due to mitophagy-inhibitory molecules. These molecules attach to mitochondria and together are transferred to TILs, which results in homoplasmic replacement. T?cells that acquire mtDNA mutations from cancer cells exhibit metabolic abnormalities and senescence, with defects in effector functions and memory formation. This in turn leads to impaired antitumour immunity both in vitro and in vivo. Accordingly, the presence of an mtDNA mutation in tumour tissue is a poor prognostic factor for immune checkpoint inhibitors in patients with melanoma or non-small-cell lung cancer. These findings reveal a previously unknown mechanism of cancer immune evasion through mitochondrial transfer and can contribute to the development of future cancer immunotherapies.

en-subtitle=

en-abstract=
kn-abstract=The PACIFIC regimen, comprising chemoradiotherapy (CRT) followed by maintenance with the immune checkpoint inhibitor (ICI) durvalumab, has become the standard of care for patients with unresectable non-small cell lung cancer (NSCLC). Although ICI is used to prevent recurrence by targeting residual microtumors, biomarkers capable of monitoring immune activity during this phase remain lacking. Here, we evaluated whether temporal changes in serum autoantibody levels can predict treatment efficacy. This retrospective study included 20 patients with unresectable stage II or III NSCLC who received the PACIFIC regimen. Serum autoantibodies against 130 antigens were quantified before CRT, after CRT, and two weeks after the first ICI dose. The primary outcome was progression-free survival (PFS), and its association with autoantibody dynamics was examined. We observed an immediate and strong autoantibody response (spark response [SR]) after ICI initiation in patients with favorable treatment outcomes. Patients with SR and programmed death ligand 1 (PD-L1) expression???50% showed better PFS (two-year PFS; 72.9% vs. 18.2%, p?=?0.0021). These findings suggest that serial monitoring of serum autoantibodies can provide a noninvasive approach to assess immune activity and predict treatment outcomes in patients receiving CRT or ICI therapy.

kn-abstract= Alzheimer’s disease (AD) is a progressive, neurodegenerative disease characterized by memory and language disorder. The accumulation of senile plaques called β-amyloid and neurofibrillary tangles involving protein tau in the brains of AD patients have been considered as two hallmarks of AD. In AD, it is reported that accumulation of β-amyloid may be observed 25 years before onset, supporting early diagnosis and treatment by brain image analysis, because several techniques have recently been developed to detect β-amyloid and tau protein in brains of persons diagnosed with AD. AD patients are usually suffering from other diseases such as diabetes or periodontal disease, and there is accumulating data to show that these diseases associate with the human microbiome, such as gut and oral microbiota. In this report, the relation ship between AD and the human microbiome is reviewed.

kn-abstract=骨・軟部肉腫は, 一部に治療抵抗性で予後の悪い症例が存在するため, 新たな治療法の確立が重要な課題である. 我々は, 5型アデノウイルスを基本骨格として, テロメラーゼ活性に依存して増殖する腫瘍融解ウイルス(OBP-301)や, coxsackie and adenovirus receptor(CAR)陰性の腫瘍細胞に感染するファイバー改変型ウイルス(OBP-405)を用い, 骨・軟部肉腫細胞に対する抗腫瘍効果を検討した.
14種類の骨・軟部肉腫細胞株に対してOBP-301の細胞障害活性を検討し, 12種類の細胞株でOBP-301に感受性を認めた. また, OBP-301の細胞障害活性はCARの発現と相関していた. さらに, テロメラーゼ活性の低い細胞に対しても, 5型アデノウイルスの複製に必須のE1Aによりテロメラーゼ活性の増強効果がおこり, 強い抗腫瘍活性を示すことを明らかにした. 次に, 骨肉腫脛骨同所性移植動物モデルを作成しOBP-301を投与したところ, OBP-301投与群では対象群と比べて有意に腫瘍増殖を抑制した. 最後に, OBP-301に感受性を認めなかったCAR陰性細胞株に対してOBP-405を用いて検討し, OBP-405が有効に作用することを確認した.
OBP-301やOBP-405を用いたウイルス療法は, 骨・軟部肉腫に対する新たな治療法となる可能性がある.

kn-abstract=Using a monoclonal antibody (Mab-G3) recognizing glomerular basement membrane (GBM), we assayed GBM antigen (G3-Ag) in the urine and serum of renal disease patients by sandwich ELISA. The subjects included normal control (NOR), minimal change nephrotic syndrome (MCNS), IgA nephropathy (IgA), membranous nephropathy (MN), membranoproliferative glomerulonephritis (MPGN) and chronic renal failure (CRF). The urine and serum was used as the material. With urinary G3-Ag, there were no statistically significant differences among the NOR, MCNS, IgA, MN, MPGN and CRF groups. Although no correlation was observed with proteinuria, hematuria, serum creatinine, serum β2 microglobulin and urinary NAG, urinary G3-Ag showed a significant (p<0.05) increase in excretion in the group of progressive CRF patients with s-Cr more than 1.0 mg/dl/month as compared to the stationary CRF group with s-Cr<1.0 mg/dl/month. Serum G3-Ag showed lower values in almost all cases, and there were no significant differences among the renal disease groups. The above findings led us to believe that the assay of urinary G3-Ag was useful in determining the degree of GBM disorder. It was also presumed that assay of renal antigens in urine and serum with the respective anti-human renal monoclonal antibodies could be a new tool in diagnosing renal diseases.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We produced 22 different kinds of monoclonal antibody (Mab) by immunizing mice with human GBM antigens. In these Mabs, Mab-G1 to G5 recognized only GBM in the glomerulas, Mab-E1 and E2 recognized only glomerular epithelial cells, and Mab-M1 to M4 recognized mainly mesangium. The reactions of these Mabs with known GBM antigens such as type IV collagen, fibronectin and laminin were negative by immunoblotting. Using Mab-G1, Mab-E1 and Mab-M1, changes in the antigenicity of antigens recognized by Mabs were examined on kidney sections from the patients with various renal diseases by the indirect immunofluorescence test. When Mab-G1 recognizing GBM was used, there was no particular change of anti-genicity in minimal change nephrotic syndrome (MCNS) and IgA nephropathy (IgA), whereas in membranous nephropathy (MN) thickened GBM was found to maintain anti-genicity and the region of deposits was observed as negative punched-out region. In type I and III of membranoproliferative glomerulonephritis (MPGN), GBM was observed only outside of subendothlial deposits without showing double contour. In type II MPGN, GBM showed a double linear pattern and antigenicity of GBM in regions of dense deposits was not detected. When Mab-E1 recognizing glomerular epithelial cells was used, there was no change of antigenicity in the renal diseases. Further, in crescentic glomerulone-phritis, the region of the cellular crescents was not stained, When Mab-M1 recognizing mesangium was used, extensive staining was observed in the increased mesangium in IgA, MPGN, and diabetic nephropathy. We feel that it is of significance in elucidating the pathogenesis of renal diseases to study the changes of glomerular antigenicity in diseased kidneys by using anti-human renal monoclonal antibodies.

en-abstract=With the brains of foetuses on the fifth gravid month and on the eighth gravid month the author isolated and estimated the free amino-acids and related substances at various parts of these brains by means of the ion-exchange chromatography, and conducted the same investigations with the normal tissues surrounding the tumor of the frontal lobe in the brain of an 18-year-old patient with tubosclerosis. 1. The quantities of free amino-acids in the foetal brains differ significantly from those in the mature human brain. 2. In the foetal brain, with some variations according to sites, amino-acids such as taurine, phosphoethanolamine, glycine and alanine, generally tend to decrease with the advance in age, while glutaminic, aspartic and γ-amino-butyric acids tend to increase. 3. In either one of the foetal brains γ-amino-butyric acid is detected in a largest quantity in the hypothalamus. 4. Cystathionine which is often detected in a large quantity in the human brain after birth can hardly be recognized in the foetal brain.

kn-abstract=By means of the ion-exchange chromatography free amino acids and their related compounds in the fresh brain tissue have been estimated. As for the test material, pieces of the cerebral cortex sectioned at the time of the surgical operation in the patients with cerebral tumor or with epilepsy are used. As the result we have obtained the following notworthy differences when compared with the results previously reported by us concerning several species of mammalians. They are: (1) In the human brain there is a conciderable amount of cystathionine. Namely, 19.4 to 43.2mg/100g wet weight, and this substance is far smaller or not recognizable in other animals; and (2) the amounts of γ-aminobutric acid and taurine are a good deal smaller than animals. Moreover, in general the pattern of the free amino acids in the human cerebral cortex may be said to resemble closely that in dog.

kn-abstract=HBs antigen was purified from the culture fluid of hepatoma huGK-14 cell line and its physico-chemical properties were studied. The purification consists of following steps: concentration of culture fluid by membrane filtration, affinity column chromatography (anti-HBs monoclonal antibody column and anti-human serum albumin antibody column), and ultracentrifugation (isopycnic centrifugation in CsCl density gradient and rate zonal centrifugation on sucrose gradient). Highly purified (purity>99%) HBs antigen was isolated with an overall yield of about 40%. The HBs antigen showed uniform spherical particles (diameter: 23.2±2.9nm) and had a specific gravity of 1.20g/cm3. The purified HBs antigen yielded, in SDS-PAGE (under reducing conditions), four protein bands with apparent molecular weights of 22,000 and 26,000 (the two major bands), and 44,000 and 47,000. The two proteins of molecular weights of 26,000 and 47,000 are likely to be glycosylated, as these were several fold reduced when the cells were cultured in the presence of Tunicamycin. Amino acid analysis, Edman degradation, carboxypeptidase digestion, and ultraviolet absorption spectrum indicated that the HBs antigen from hepatoma cells is very similar to that derived from human plasma.

kn-abstract=Osteosarcoma is a malignant bone tumor which usually occurs in the metaphysis of long bones in adolescents or young adults, but the mechanism of disease occurrence is unknown. To examine alterations in the dominant oncogenes in the osteosarcoma and other bone and soft tissue tumors, DNA extracted from 12 bone tumors, 12 soft part tumors and 2 cells lines was hybridized with c-oncogene (c-myc, c-sis, c-raf-1, c-fos, K-ras2, c-erbB, c-fms, c-fos). DNA extracted from the same samples was examined with Rb cDNA (p0.9R, p3.8R) probes, the retinoblastoma gene (Rb gene) localized at 13q14, to analize whether a recessive mutation is a target in osteosarcoma, and other bone and soft tissue tumors. Amplification of c-myc was observed in 3 cases from 7 osteosarcomas and abnormalities in structure of the Rb gene were found in 4 from 7 osteosarcomas, 2 from 4 MFH, and 1 from 2 Ewing's sarcomas. Both amplification of the c-myc and abnormalities of the Rb gene were observed in 3 osteosarcoma cases. The results indicated that both the Rb gene and c-myc oncogene may be involved in the initiation of osteosarcoma.

kn-abstract=The effectiveness of hyperthermia in combination with anticancer drugs on EBC-1 cell line established from a patient with pulmonary epidermoid carcinoma was investigated. Anticancer drugs tested in the present study were adriamycin, bleomycin, cisdichlorodiammineplatinum (II) and mitomycin C. EBC-1 cells were incubated with the drug for one hour at 37°C or at elevated temperature (41°C, 42°C and 43°C). The enhancement of cytotoxicity by hyperthermia was found in combination with all of the drugs. The degree of enhanced cytotoxicity was positively elated to the temperature in combinations with adriamycin and bleomycin. Especially, a synergic enhancement of cytotoxicity was found with the combination of hyperthermia and bleomycin. The present study showed that the combination of hyperthermia and anticancer drugs produced potential cytotoxicity on EBC-1 cells in vitro, and may provide useful information for the clinical trials in the future.

kn-abstract=Chemotherapy is the only therapeutic modality applicable to patients with advanced pulmonary epidermoid carcinoma (PEC). However, the results of chemotherapy to PEC remain unsatisfactory. It is very important to have an accurate knowledge of the sensitivity of anticancer drugs against PEC in order to establish a successful chemotherapy. The in vivo sensitivity of 12 anticancer drugs was investigated using PEC cell line (EBC-1) xenografts in hamsters.
In the present study, adriamycin, ifosphamide, mitomycin C, methotrexate and cisdichlorodiammineplatinum (II) showed antitumor activity against EBC-1 cells, but the other 6 drugs (ACNU, bleomycin, 5-fluorouracil, neocarzinostatin, procarbazine and vincristine) have no antitumor activity against EBC-1 cells. These results suggest that combination chemotherapy with 3 or 4 drugs with antitumor activity in the present study may be effective to PEC.

en-abstract=
kn-abstract=Sequences related to the squirrel monkey retrovirus (SMRV) LTR were isolated from a genomic library of human DNA by screening under conditions of relaxed stringency. The probe contains several transcriptional signals and its regulatory sequences in SMRV-H LTR, such as the enhancer sequence, CAT box, TATA box, and polyadenylation signal. More than 50 positive signals were detected in 4.4×105 recombinant phages. The cloned human sequences named SRH strongly hybridized with SMRV-H LTR and some of them weakly hybridized with SMRV-H structural genes. In SRH-1, the region related to SMRV-H prt-pol-env was flanked by the two separately located sequences related to the LTR. SRH-3 has a solitary LTR-related region, whereas, in SRH-5, the LTR-related region was adjacent to the pol-env-related sequence. The reliability of these hybridization experiments was confirmed by reciprocal hybridization. The restriction enzyme cleavage maps of these clones were different from those of known human endogenous retroviruses. Alu sequences, a human highly repetitive sequences, were inserted to the LTR-and pol-env-related regions in SRH-5.

kn-abstract=Immunoelectron microscopic observations of human immunodeficiency virus (HIV) antigens were made using the indirect peroxidase-labeled antibody method with monoclonal antibodies (MoAb) to the envelope glycoprotein (gp160/120), matrix protein (MA, p17), and capsid protein (CA, p24). Antigens in the virions and HIV-infected cells were detected in frozen-sectioned specimens. Positive immunoreaction of MoAb to gp160/120 was located on the viral envelope, plasma membrane, endoplasmic reticulum, and nuclear membrane. The reaction of MoAb to p17 was at the inner leaflet of the viral envelope and the nucleoid. The reaction of MoAb to p24 was localized on and around the viral core. In cell suspension, however, positive immunostaining was observed only on the surface of the viral envelope and plasma membrane with MoAb to gp160/120, and no positive staining was observed with MoAb to p17 and MoAb to p24. The reaction of HIV-infected cells with normal control serum and all of the reactions in uninfected cells with these MoAbs were negative. It appears that antibodies have difficulty penetrating into virions and cells in cell suspension.

en-abstract=
kn-abstract=Squirrel monkey retrovirus (SMRV) is an endogenous type D retrovirus of the squirrel monkey, a New World primate. Southern hybridization with cloned SMRV-H revealed that 3040 copies of SMRV proviral DNA are present in the squirrel monkey genome and the majority have almost the same physical map as that of the cloned SMRV-H. SMRV-related sequences in the human genome were sought using the same method with various cloned SMRV-H DNA fragments under conditions of relaxed stringency. The discrete restriction fragments were frequently detected in the DNA from normal humans with the LTR and parts of gag and env as probes. Since SMRV LTR has very little homology with the LTRs of other retroviruses, the fragments detected with the LTR probe were characterized as SMRV-related human sequences. SMRV LTR-related sequences were also detected in the African green monkey and chicken, but not in the salmon, mouse, or dog. In conclusion, SMRV-related sequences are present in human DNA, and some of them might represent endogenous retroviral sequences of human DNA.

kn-abstract=The amplification and rearrangement of five cellular oncogenes (c-myc, c-K-ras, c-fos, c-raf-1, and N-myc) were studied by Southern hybridization in fourteen human bone and soft tissue tumors obtained at surgery. Amplification of c-myc was detected in the two of four osteosarcomas and one of two malignant fibrous histiocytomas. The c-myc genes in these tissues were amplified 4- to 8-fold in comparision with the placenta DNA. One of these osteosarcomas had 16- to 32-fold amplification of c-raf-1 gene without rearrangement. The clinical course of osteosarcoma and malignant fibrous histiocytoma with the amplified c-myc or c-raf-1 gene showed a rapid malignant progress with lung or bone metastasis. There appears to be a correlation between clinical prognosis and oncogene amplification.

kn-abstract=Primary culture of human primary liver cancer tissues treated with or without trancatheter arterial embolization (TAE) was perfomed with the following results. 1. The yield and viability were very low in cells from primary liver cancer tissues dissociated with enzymes. 2. Epithelial-like cells were found from TAE-treated cancer tissues at a ratio of 1/8 in both monolayer and explant culture and from TAE-nontreated tissues at a ratio of 4/12 in monolayer culture and 3/12 in explant culture. The AFP-producing capahity of these epithelial-like cells has been maintained from one week to one month in culture. 3. Cells derived from two TAE-nontreated cancer tissues were subculturable. One was established as a cholangiocellular carcinoma cell line. 4. No heterotransplantability of primary cultured cancer cells into nude mice was found.

kn-abstract=Membrane changes of DAB hepatic carcinoma cells were examined immunohistochemically, using the binding activity of Arachis hypogaea agglutinin (PNA) and anti-liver membrane antibody (anti-LM) from patients with HBsAg-negative chronic active hepatitis. The hepatic carcinoma in rats was produced through DAB feedings for 3-5 months. As controls, non-cancerous liver tissues from rats fed DAB, and normal rat liver were used. In isolated calls of the hepatic carcinoma and control tissues, FITC-PNA binded in 10 of 11 cases of DAB hepatic carcinoma and in none of control cases (11 rats fed DAB and 2 normal rats). In tissue sections, similar results were obtained. Lens culnaris agglutinin did not show any difference in binding among the 3 groups. Two anti-LMs did not bind to the membranes of isolated calls in 3 of 10 DAB hepatic carcinomas, although the anti-LMs were bound in all of controls. These facts indicate that the transformation, DAB hepatic carcinoma cells is accompanied by changes in the cell membrane, and that PNA may be useful in the analysis of membrane changes in carcinogenesis.

kn-abstract=Experimental evaluation of a new chemosensitivity test using a subrenal capsule assays (SRC) was performed. The effects of various immunosuppressants-cyclosporin A (CSA), cyclophosphamide, whole body irradiation, and Bredinin were studied using human small cell lung cancer cell line (SBC-3) serially transplanted in nude mice. A significant degree of host cell infiltration was seen in tumor fragments implanted under the renal capsule of immunocompetent mice. However, treatment with immunosuppressants effectively suppressed the host immune reaction. The most effective immunosuppressant was CSA at 60mg/kg. We compared the antitumor activities of CDDP, MMC, VP-16, ADM, CPA, and VCR against SBC-3 using SRC and clonogenic assays. SRC was performed using mice administered CSA 60mg/kg. Chemotherapeutic agents (1/2 LD(10)) were administered on day 1 and antitumor activities were evaluated on day 6 after implantation. The results of the assays were well-correlated except with VCR.

en-abstract=
kn-abstract=A human monoclonal antibody (IgG) against Pseudomonas aeruginosa was established within 3 weeks after fusion of patient lymphocytes and human myeloma WIL2-86 cells. This method is useful in establishing human monoclonal antibodies for infectious bacteria of a variety of antigenicities and allows for use of such antibodies as immunotherapeutic drugs in chronically infected patients. The opsonic effect of the monoclonal antibody we established was 1.8-fold higher than that of commercially available immunoglobulin drugs. Since the established human monoclonal antibody recognizes serotype M, which has not yet been produced, the antibody may be used as a part of immunotherapeutic drug “cocktail”.

kn-abstract=Morphological changes in human basophils from atopic asthmatics were observed in whole blood smears with respect to histamine release after stimulation with antigen or anti-IgE. Histamine was rapidly released and was accompanied by morphological changes in basophils upon stimulation with antigen and anti-IgE. A decreased number of basophils and morphological changes including increased cell diameters, increased ratios of the short to long axis diameters, and decreased intracellular granule counts were observed upon the release of histamine after antigen and anti-IgE stimulation. Antigen stimulus induced both more rapid histamine release and morphological changes than anti-IgE stimulation.

kn-abstract=Immunohistochemical localization of α and β subunits of the S-100 protein in normal human brains and brain tumors was studied by the ABC method using mouse monoclonal antibodies against each subunit. In cerebral tissues, glial cells showed positive staining for both subunits, with some neurons positive only for the α subunit.
In cerebellum, Purkinje cells and other neurons were negative for the α or β subunit, and Bergmann's cells were positive only for the β subunit. Low grade astrocytomas were strongly positive for the α and β subunits. In oligodendrogliomas and choroid plexus papillomas, the immunoreactivity of the β subunit was stronger than that of the α subunit. Medulloblastomas showed no positive staining for either subunit. Schwannomas were positive only for the β subunit. High grade astrocytomas, ependymomas and meningiomas manifested marked variability in the immunoreactivity for the α and β subunits of the S-100 protein. The evidence suggests that immunohistochemical examination of the α and β subunits of the S-100 protein in normal human brains and brain tumors may be useful in determining the histogenetic origin of brain tumors.

kn-abstract=A cell line, HuH-33, was established in vitro from a patient with hepatocellular carcinoma (HCC), who had been treated with some chemotherapeutic agents. The chromosome number was widely distributed in 6888. This cell line has grown slowly, exhibiting a doubling time of approximately 150h, was intransplantable into nude mice, and secreted alpha-fetoprotein, albumin, β2-microglobulin, ferritin, tissue peptide antigen and extracellular matrix materials. HuH-33 was polygonal or spindle shaped, but it was keratin-positive and desmosome-like structures were observed with transmission electron microscopy, suggesting an epithelial origin of HuH-33.

kn-abstract=The human growth hormone (hGH) in lung cancer was studied immunohistochemically in 160 patients by the PAP method. Thirty-four neoplasm specimens (21.3%) contained hGH-positive tumor cells. Positive reaction for hGH was shown in 19 of 64 squamous cell carcinomas, 13 of 48 adenocarcinomas, 2 of 5 carcinods, and none of 26 small cell carcinomas and 17 large cell carcinomas. The sensitivity for hilar type lung cancer was higher than that for peripheral type (p<0.05). Positive rates for hGH were not affected by age, sex, tumor size, lymph node involvement or postsurgical stage. The survival rate of hGH positive patients was not worse than that of hGH negative.

Basophils from one patients with asthma released no significant amount of histamine by anti-IgE.

en-abstract=ヒスタミン自動分析装置により,健康人10名,気管支喘息23例の全血からのヒスタミン遊離を測定した. 抗ヒトIgEを添加した際のヒスタミン遊離は,健康人および外因性気管支喘息症例では有意の増加傾向を示したが,一方内因性喘息症例では遊離増加はほとんどみられなかった. ハウスダスト抗原添加では,ハウスダストが抗原である気管支喘息症例においてのみ全血からの有意のヒスタミン遊離の増加が観察された. 以上の結果より,ヒスタミン自動分析装置による全血からの遊離ヒスタミンの測定は,気管支喘息の病態解明の1手段として極めて有用であると考えられる.
kn-abstract=Histamine released from whole blood was determined by an automated fiuorometric histamine analysis system. The increased release of histamine from basophils by anti-IgE was observed in ten healthy subjects and 12 extrinsic asthma patients, while the release in 11 intrinsic asthma patients was significantly less as compared to that in healthy and extrinsic asthma subjects. House dust extract caused a significant increase in the histamine release from basophils of the extrinsic asthma patients who are sensitive to house dust. It was concluded from this study that histamine released from basophils could be easily determined by an automated analysis system and that the
method is useful for the diagnosis and study of allergy.

kn-abstract=Histamine release from basophils induced by anti-IgE was examined in 14 asthmatic subjects with blood eosinophilia. The subjects were divided into two groups; group I (with blood eosinophilia, positive skin test and positive RAST to house dust) and group II (with blood eosinophilia, negative skin test to various allergens and negative RAST to house dust). 1. Serum IgE levels in group I were much higher than those in group II. 2. Maximum percent histamine release induced by anti-IgE was much higher in group I than in group II. 3. Dose-response curve of anti-IgE-induced histamine release in group I showed consistent increase as anti-IgE concentrations increased. while, dose-response curve in group II was very low. These findings suggested that blood eosinophilia in group I might be elicited relating to IgE-mediated reaction. However, mechanism causing eosinophilia in group II was not clear in the present study.

kn-abstract=Histamine releasse from basophils induced by house dust and C. albicans was examined in 30 patients with bronchial asthma. House dust and C. albicans caused a significant amount of histamine release in subjects with a RAST score to corresponding allergen. A close correlation was found between house dust- and anti-IgE-induced histamine release. However, histamine release induced by C. albicans was considerably different from the release induced by anti-IgE.

kn-abstract=過去3年間にわたり,気管支喘息患者末梢血好塩基球からのヒスタミン遊離について,ヒスタミン自動分析装置を用いて全血法により検討を加えてきた. 1. 抗ヒトIgE によるヒスタミン遊離は,症例間で著しい差がみられた. この際血清IgE値が高値を示す症例では全般的に高度なヒスタシソ遊離がみられたが,血清IgE値が正常かまたはむしろ低値を示す症例のヒスタミン遊離は,かなり高度なものから全くみられないものまでさまざまであった. 2.ハウスダストやカンジダなどの抗原物質によるヒスタミン遊離は,特異的IgE抗体依存性であり,抗体価が上昇するにつれヒスタミン遊離は高度となる傾向がみられた. しかし,ハウスダストとカンジダによるヒスタミン遊離には若干の差がみられた. すなわち,ハウスダストと抗ヒトIgE によるヒスタミン遊離の間には密接な関連がみられたが,カンジダと抗ヒトIgEの間には全く関連がみられなかった. またカンジダによるヒスタミン遊離においては,IgE系反応以外の反応が関与する可能性が一部示唆された.

kn-abstract=癌抑制遺伝子p53の突然変異や欠損による機能的異常は、多くのヒト癌で普遍的かつ高頻度に認められている。p53タンパク質の機能の一つとしては、細胞増殖に関するいろいろな遺伝子の発現制御を介した細胞周期の調節が考えられているが、その他に最近アポトーシスの誘導分子としても注目を浴びてきている。正常型p53遺伝子を有する胃癌、大腸癌では、術前化学療法や放射線療法で癌細胞のアポトーシスが誘導されたが、変異型p53を発現する腫瘍
ではアポトーシスに陥った細胞はほとんど認められなかった。ヌードマウスの皮下に移植したp53遺伝子に異常を持つヒト肺癌腫瘍にリコンビナント・アデノウイルスベクターを用いて正常型p53遺伝子を導入すると、抗癌剤に対する感受性が劇的に増強し、シスプラチンの腹腔内投与により腫瘍内にアポトーシスによる広範囲な組織破壊が認められた。この正常型p53発現アデノウイルスベクターとDNA障害性抗癌剤を併用した遺伝子治療は、臨床的にヒト悪性腫癌に応用可能と考えられる。

kn-abstract=Meg1/Grb10遺伝子導入マウス(Meg1マウス)はインスリンのシグナル伝達阻害による高インスリン血症を呈することから2型糖尿病モデルと考えられている。Meg1マウスは肥満を伴なわずに高血糖を発症するが、脂肪・カロリーの過剰摂取によっても糖尿病の発症が著しく増加する。本研究はMeg1マウスの2型糖尿病モデルとしての有用性を検討するために、Meg1マウスと対照マウスを高脂肪・高カロリー飼料(HFD)及び対照飼料(NFD)で飼育した時の血漿アディポネクチン量とBMI値を比較するとともに糖尿病関連遺伝子の発現量について他の糖尿病モデルマウスと比較検討した。血漿アディポネクチン量はMeg1マウスのHFDが最も高く、対照マウスのNFDが最も低い値を示した。一方、BMI値は対照マウスのHFDが最も高い値を示し、血漿アディポネクチン量とBMI値は逆相関が認められ、ヒト2型糖尿病と類似することが認められた。また、Grb10、Glut4遺伝子の発現量はMeg1マウスと他の糖尿病モデルマウスでは異なる値を示し、Meg1マウスでのGrb10遺伝子の発現量は高く、Glut4遺伝子の発現量は低かった。以上のことから、Meg1マウスには他の糖尿病モデルと異なる発症機構の存在が示唆され、Meg1マウスは2型糖尿病モデルとしての有用性が考えられた。

kn-abstract=Human blood serum and various organs of dogs were determined for its content of parathion-splitting enzyme by the procedure presented in the preceding paper. Ten per cent saline suspension of the relevant homogenized tissues was used for the estimation of parathion-splitting enzyme of the organs. (1) The activity of the enzyme in blood serum of normal individuals was 134 ± 44.6 γ/ml for men and 180 ± 62 γ/ml for women. (2) Of the various organs of dogs the blood serum was the most abundant in the enzyme, and the liver, the lung, the bone marrow and the kidney followed in the order given. The distribution of the enzyme was not appreciable in other organs. (3) The blood, the liver, the lung and the bone marrow were thought to play a major part in the detoxication of parathion, because the afore-mentioned decomposition of this poison to the less toxic paranitrophenol was believed to imply detoxication. The blood will constitute the most important and the liver the next-important organ of detoxication, if volume of the organs is taken into account.

en-abstract=気管支喘息50例,慢性気管支炎8例を対象に,抗ヒトIgE添加時の好塩基球からのヒスタミン遊離を全血法により行ない,その臨床的評価について検討を加えた。抗ヒトIgE海底時のMax % histamine releaseの平均は,健康人24.7±14.2%,慢性気管支炎27.7±22.1%,気管支喘息28.4±17.0%であり,3者間に有意の差はみられなかった。すなわち,抗ヒトIgE添加により健康人や慢性気管支炎患者の好塩基球からも有意のヒスタミン遊離が見られた。気管支喘息のなかでは,内因性喘息症例においてヒスタミン遊離(14.1±7.2%)の低い傾向が見られた。Dose-response curveの検討では,健康人,慢性気管支炎症例では全例E(2)からE(1)へかけてのnegative slopeを示した。気管支喘息症例では,血清IgE値500IU/ml以下の症例ではnegative slopeを示す症例が多く,一方501IU/ml以上の症例ではpositive slopeを示す症例がより多く見られた。
kn-abstract=Histamine release from basophils induced by anti-IgE was studied in 8 patients with chronic bronchitis and 50 patients with bronchial asthma by analyzing doseresponse curves. As the result, there were no significant differences in maximum percent histamine release from basophils among three groups of healthy subjects (24.7±
14.2%), patients with chronic bronchitis (27.7±22.1%) and those with bronchial asthma (28.4±17.0%). In the patients with bronchial asthma, the maximum percent histamine release was higher in accordance with higher serum IgE levels, and low maximum percent release was observed in patients with intrinsic asthma (14.1±7.2%).
Study of dose-response curves of anti-IgE-induced histamine release showed that a negative slope from E(2) to E(1) was observed in both healthy subjects and patients with chronic bronchitis. The majority of asthmatics with serum IgE levels of 501IU/ml or over showed a positive slope from E(2) to E(1).

kn-title=Terfenadineの抗アレルギー作用について
en-subtitle=
kn-subtitle=
en-abstract=Anti-allergic action of terfenadine, one of the H(1) receptor inhibitors, was examined by human basophil histamine release induced by anti-IgE or a specific allergen (house dust), and the release of leukotriens from leucocytes stimulated by Ca ionophore A23187. 1. Terfenadine did not inhibit the release of histamine from basophils of healthy subjects induced by anti-IgE, and also of patients with bronchial asthma induced by house dust when the in vitro examination was performed by a whole blood method. 2. Histamine release from basophils of patients with bronchial asthma was significantly inhibited
when washed leucocytes was preincubated with terfenadine in vitro. The release of LT B(4) from leucocytes was also inhibited. 3. In vivo examination of inhibitory action of terfenadine showed no effect on basophil histamine release of healthy subjects by anti-IgE and of asthmatic subjects by house dust, although skin test by house dust in these subjects was inhibited 60 min after administration in vivo.
These results show that terfenadine inhibits the release of chemical mediators from tissue mast cells, and basophils migrating into local allergic sites.
kn-abstract=選択的H(1)受容体拮抗薬であるTerfenadineの抗アレルギー作用,特にIgE系反応によるヒスタミン,およびCa ionophore A23187による好中球からのleukotrienes遊離に対する抑制作用を,ヒト末梢血白血球を用いて検討した。1.Terfenadineは,抗ヒトIgE刺激による健康人好塩基球および特異抗原刺激による気管支喘息患者好塩基球からのヒスタミン遊離に対して,全血法でのin vitro添加実験では有意の抑制作用を示さなかった。
2.洗浄白血球法によるin vitro添加実験では,Terfenadineは特異抗原および抗ヒトIgE刺激時の気管支喘息患者好塩基球からのヒスタミン,Ca ionophore A23187刺激時のleukotriene B(4)遊離に対して有意の抑制効果を示した。3.Terfenadineの内服によるin vivoの抑制実験では,IgE系反応による健康人および気管支喘息患者好塩基球からのヒスタミン遊離に対して有意の抑制効果は見られなかったが,特異抗原による皮膚反応に対しては明らかな抑制作用が観察された。以上より,Terfenadineは,組織肥満細胞および組織へと遊走してきた好塩基球に対してはある程度の抑制作用を有しているものと考えられた。

en-abstract=Tlanilast is clinically used for bronchial asthma as one of the prophylactic agents for asthma attacks. In this study, anti-allergic actions of tranilast were examined in (45)Ca uptake of and histamine release from target cells of IgE after stimulation with antigen, anti-IgE and camp. 48/80. 1. (45)Ca uptake of and histamine release from rat peritoneal mast cells stimulated by antigen were significantly inhibited by preincubation of the cells with tranilast. Inhibition by tranilast of increased (45)Ca uptake of mast cells by addition of phosphatidylserine were less, although inhibition of histamine release was not so affected by addition of phosphatidylserine. No significant inhibition by tranilast of (45)Ca uptake and histamine release was not observed when the cells were stimulated by camp. 48/80. 2. Tranilast showed any inhibitory effects on basophil histamine release induced by antigen and anti-IgE.

They were repeatedly injected to pregnant rabbits as antigens, and the following are the results. There are caused the allergic histological changes on liver and kidney outstandingly, the changes are alike to the organs of pregnant toxicosis, and are the most strongest when injected placental protein, more stonger fetal serum than amniotic fluid. However any differences cann't find out among themselves histologically, so the author has considered that the specific protein is caused to the above said changes.

en-abstract=With the use of homogenate of the brains and cerebral cortex slices obtained from albino rats, Pithecus monkey and human, the author observed the influences of electrical stimulation (in vitro) on the fransamination, and obtained the following results. 1. In the case of albino rat cerebrum the electrical stimulation inhibited the synthesis of glutamic acid from the aspatic acid 14.6 per cent with homogenate and 9.6 per cent with slices. Namely, the rate of such inhibition seems to he greater in the case of homogenate than in the case of slices. In addition, in the alanine series ne marked changes could be recognired but in GABA series all tended to receive a slight inhibitory effect. In all cases, however, the rate of reactivity is diminished more with slices than with homogenates. 2. In the case of the cerebral cortex homogenate of monkey, the electrical stimulation inhibited the glutamic and production in the aspartic acid seriet about 11 per cent on the average. In the case of the normal human cerebral cortex slices, the electrical stimulation accelerated the glutamic acid production about 11.3 per cent on the average, while in the case of atrophic human cerebral cortex homogenate hardly any changes could be recognized. In comparing the rats of reactivity in the case of the normal human cerebral cortex slices it is about 20 per cent higher both in the control group and experimental group than in the case of the slices of albino rats. In the cisa of the atrophic human cerebral cortex homogenate the reactivity was slightly lower than in the case of albino rats.
kn-abstract=1) ダイコクネズミ,タイワンザル,ヒト脳の大脳ホモジネートおよび大脳皮質切片を用いて電気刺戟(in vitro)のトランスアミネーションにおよぼす影響をみた. 2) ダイコクネズミ大脳においてはAsGT活性は電気刺戟によつてホモジネートでは14.6%切片では9.6%阻害された.すなわちホモジネートの方が切片より阻害率は著明なようであつた.またAIGT活性は電気刺戟によつてホモジネート,切片とも著変なく,γAGT活性は電気刺戟によつてホモジネート,切片とも阻害傾向を示した.そこでAIGTは酵素系が異なるためではないかと推論した.また反応率はいづれの場合も切片の方がホモジネートより減少していた. 3) タイワンザル大脳皮質ホモジネートにおいてはAsGT活性は電気刺戟によつて平均約11%阻害された.またヒト健常大脳皮質切片においてはAsGT活性は電気刺戟によつて平均約11.3%の促進をみ,ヒト萎縮大脳皮質ホモジネートにおいては殆ど変化をみなかつた.また反応率を比較するとヒト健常大脳皮質切片ではダイコクネズミの切片の場合に比し対照時,刺戟時ともに約20%高く,ヒト萎縮大脳皮質ホモジネートではダイコクネズミのそれに比しやや低い値を示した.すなわち萎縮脳のAsGT活性の低下が考えられる.

kn-abstract=Followings are the results of studies by our clinical tissue culture method mainly on motility and ability of platelet formation of megakaryocytes in the spleen of human embryo and a patient with osteomyelofibrosis. 1) Megakaryocytes are always found in the spleen of human embryo, and no significant morphological differences are noted from those in the bone marrow. 2) Deformated movement, pseudopodial movement, and tentacle formation for the platelet formation are noted on megakaryocytes in the spleen of human embryos. As for functions of megakaryocytes, motility and ability of the platelet formation are significantly found at 4 month of age, but are remarkably decreased after 5 month of age. 3) A correlation is noted in human embryo between the functions of megakaryocytes and erythropoiesis in the spleen, a rise and fall of the one being accompanied by the other. 4) In a patient with osteomyelofibrosis, megakaryocytes found in the spleen show a remarkable decrease in the functions.

kn-abstract=By means of ion exchange column chromatography the author carried out quantitative analyses of 14 kinds of free amino acids including the related compounds using the brain of the person who died of acute loss of blood. The parts of the brain used for the analysis were frontal cortex, corpus callosum, caudate nucleus, globus pallidus, thalamus, hypothalamus and medulla oblongata. The results are as follows. 1. In corpus callosum which contains little cellular components extremely minute quantities of phosphoethanolamine, aspartic acid, glutamic acid and γ-aminobutyric acid could be detected. 2. In globus pallidus a surprisingly large quantity of γ-aminobutyric acid could be found and it was far greater than that contained in hypothalamus. 3. In medulla oblongata only small quantities of phosphoethanolamine, aspartic acid, and glutamic acid could be detected. Likewise γ-aminobutyric acid was found not so abundant. This seems to be due to the fact that the present experiment was conducted with medulla oblongata including white matter. 4. Although only in a small quantity, cystathionine could be assayed in all these parts except globus pallidus and thalamus. 5. Even from the comparative biochemistry the present quantitative analyses gave an interesting contrast to the values obtainable in the brains of lower animals. 6. Although it was difficult to recognize any distinct difference in the pattern of amino acids between the adult brain and the infant brain, there was a clear-cut difference in the amino acid pattern of the adult brain and that of the fetal brain. Namely, in the adult human brain there exist far greater quantities of aspartic acid, glutamic acid, γ-aminobutyrie acid, and N-acetylaspartic acid than those in the fetal brain and conversely far less quantities of phosphoethanolamine and taurine than in the latter. Likewise tyrosine detected in the fetal brain could not be recognized in the adult human brain.

en-abstract=The author measured the transaminase activities of eighteen amino acids with α-keto-glutarate in a Pithecus monkey brain and in two human brains, one obtained from a man died from accident and another from a woman died of senile psychosis due to brain atrophy. 1. In the monkey brain, alanine and valine showed low activities in the cerebral cortex in comparison with other parts but γ-amino-β-hydroxybutyric acid showed a low activity. 2. In normal human brain, lower activities of valine, leucine and three ω-amino acids were showed in the cerebral cortex, which were different from the monkey and lower vertebrates. 3. The markedly atrophic cerebral cortex was more similar to the lower vertebrates than to the normal human brain in high activities of alanine, leucine, valine and γ-amino-β-hydroxybutyric acid. But an increase of activities of histidine, proline and ornithine was not similar to both of normal human and animal brain. These high activities of histidine and praline correspond unlikely to the transamination only.

en-abstract=With the cerebellum of albino rat, human and cat as the material the activities of lactate dehydrogenase (LDH), succinate dehydrogenase (SDH), and α-glycerophosphate dehydro-genase (α-GPDH) were studied histochemically. For the identification of SDH and α-GPDH, menadione (MD) was added to the incubation medium as an intermediator. In the freshly-prepares cryostat sections of the cerebellum, the activities of LDH and SDH, as has already been reported, have been found in the granular layer (glomeruli cerebellosi), molecular layer and Purkinje cells (P-cells), but the activity of α-GPDH has hardly been detected in P-cell layer. In contrast to this findings, when the tissue block was first fixed with cold formalin solution and then frozen sections were prepared, in the course of identification of α-GPDH the formation of Nitro-BT formazans was observed in P-cells. This fact in dicates that a special precaution is required in the selection of methods and the determination of results inthe enzyme histochemistry. From this point of view, the establishment of various experimental conditions optimal for such a study have been tried with a specal reference to the problem of the fixation.
The following results have been fouud with regard to the reaction in the sections fixed with formalin: 1) there is no marked difference due to the length of fixation time: 2) there is little effect due to the change in pH: 3) no specific inhibitory effect can be observed: 4) the presence of MD is prerequisite; 5) SH-group is involved; and 6) the enhancement of incorporation (adsorption; cf: substativity; Pearse) of Nitro-BT to the tissue is associated with the reaction. From these findings I have postulated that the reaction observable in the formalinfixed sections results from non-enzymic reaction in which SH-group and MD are involved, on the assumption that Nitro-BT is bound to the tissue protein. Furthevmore, the findings that P-cells do hardly exhibit the activity of α-GPDH in the non-fixed sections different from other cellular components of cerebellar tissue, as well as the fact that the non-enzymic recuction of Nitro-BT appears markedly in P-cells of the formalin-fixed specimen, seem to reflect one aspect of the cytochemical specificity of the P-cells.
kn-abstract=(1) ダイコクネズミ及びヒト,ネコの小脳について,乳酸脱水素酵素(LDH),コハク酸脱水素酵素(SDH),α-グリセロ燐酸脱水素酵素(α-GPDH)活性を組織化学的に検索した. SDH,α-GPDHの検出にあたつてはintermediatorとしてmenadione (MD)を反応液に添加した. 新鮮凍結クリオスタット切片にて,LDHは顆粒層の“gloneruli cerebellosi”に相当して最も強く,分子層ではformazan顆粒はびまん性に形成されて反応は顆粒層よりやや弱くPurkinje細胞(P-細胞)は核を除いて細胞体に強度〜中等度の活性を示し,白質には活性はほとんど証明されなかつた. SDHは全体としてLDHの反応態度に似た像を示し,顆粒層に最も強く,ついでP-細胞層,分子層の順で活性が認められ,白質にはほとんど証明されなかつた. α-GPDH反応は,顆粒層,分子層においてはLDH, SDHとほぼ同じであるが,P-細胞層にはformazanの形成がほとんどなく,あたかも顆粒層と分子層の間に空隙がある様な像を示した.白質には活性はほとんど証明されなかつた,これらの所見は,これまでの報告にほぼ一致するものである. (2) 上記酵素活性の検出にあたり,新鮮凍結クリオスタット切片とともに,同一材料について組織塊をまず10%冷フォルマリンで固定した後に作製した凍結切片をあわせて使用した. SDH,α-GPDH, LDHともに反応は全般に減弱されるが,LDHの反応の減弱の度合は他の2者にくらべて少ないようであつた.
ここで注目すべきことは,非固定切片のP-細胞層において,α-GPDHの活性がほとんど認められなかつたにもかかわらず固定切片のP-細胞には反応が認められ,しかもformazan形成は他の部よりもむしろ強度であつた点である.この事実は酵素組織化学における方法の選定や結果の判定にあたつては常に慎重な配慮が要求されることを示す現象であるとみなされ,この点に着目し特に固定の問題をめぐつて諸種の条件を実験的に設定してしらべた. (3) フォルマリン固定切片における反応には, i) 固定時間の長さによる著明な差異がみられない. ii) pHの変化による影響が少ない. iii) 特異的抑制剤による影響がみられない. iv) MDの存在が不可欠である. v) SH-基の関与がある. vi) Nitro-BTの組織への吸着性の増強が関連している. ということを認めた. このことからフォルマリン固定切片に見られる反応は,Nitro-BTの組織蛋白との結合性を前提とて,SH-groupとMDとが関与している非酵素的作用の結果であることを推論した. (4) 小脳組織でP-細胞が他の細胞要素と異なり,非固定切片においてα-GPDH活性をほとんど示さないこと,およびフォルマリン固定によりP-細胞に非酵素的なNitro-BT還元が著明にあらわれることは,P-細胞の細胞化学的特異性の一面を示すものであろう.

kn-abstract=Malic dehydrogenese (MDH) activities in human serum of various diseases were studied. Elevation of MDH activities were observed in myocardial infarction, acute hepatitis, and some malignant tumors. Characteristic MDH isozyme patterns were obtained from serum of patients with myocardial infarction and acute hepatitis showing marked elevation of MDH activities. During the tetrazolium procedure for staining of electrophoreticaly separated serum malic or lactic dehydrogenese isozymes on agargel, without substrate and co-enzyme, two peaks were noticed and named serum "non-specific factor". These peaks were considered a kind of non specific reactions which resulted from a reduction of the tetrazolium salt electrostaticaly adsorbed on Alb. 〜 α(1), Glb. by SH-groups of these serum proteins. These reactions were accelerated by the elavation of PH or the temperature, exposure during staining and the prolonged staining time, as well as the rise of concentrations of NTB, PMS and CN- in the staining medium. Considering of optimal conditions of enzyme reaction, the minimum use of NTB, PMS and Na CN, washing stained agargels with PH 4.5 acetic acid SoL, and complete shading during procedure could minimize the influence of this factor. Two MDH isozymes were demonstrated in agargel isozymograms of rat organs, one migrating towards the cathod and the other toward the anode. The cathodal fraction was considered mitochondrial MDH (m-MDH), and the anodal one cytoplasmic MDH (c-MDH), respectively. During development, m-MDH showed marked increase in heart muscle. In contrast to this, cMDH of liver and gastric mucosa increased in procedure of development. On the other hand the ratio of m-MDH and c-MDH in kidney remained constant through development.

kn-abstract=Malic dehydrogenese (MDH) activities and isozymes of various human organs were measured. The assays of isozyme were carried out by means of agargel electrophoresis. The highest MDH activity was demonstrated in heart muscle. Liver, skeletal muscle, kidney and brain showed considerably high MDH activities. Six fractions were distinguished in many MDH isozymograms. In order of movility towards the cathod, each MDH isozyme was named MD(1), MD(2)…MD(6). Intracellular distribution of each MDH isozyme was investigated by means of cell fractionation, and MD(1)〜MD(5) were confirmed mitochondrial, MD(6) cytoplasmic, in origin. MDH isozyme-patterns of human organs were divided into 3 groups according to the ratio of mitochondrial MDH (m-MDH) and cytoplasmic MDH (c-MDH).
Group T (m-MDH>c-MDH): heart muscle, kidney, skeletal muscle, white blood cell, red blood cell and lung-tissues.
Group U (m-MDH≒c-MDH): liver, pancreas. Group V (This group situates between Group T and Group U): brain, gastric mucosa, and spleen. Studies on inhibitory effect of p-chlor-mercuri-benzoate (PCMB) on each MDH isozyme and heat stability of each MDH isozyme demonstrated that m-MDH was not inhibited by PCMB and stable to a heat test at 50℃ for 30,' when 1-malate was used as substrate. It was also observed that m-MDH was activated by a high concentration of 1-malate. According to the standard deviation of MD(6) and MD(3) activites, c-MDH considered regulatory enzyme and m-MDH constitutive enzyme, respectively.

kn-abstract=Cortical evoked responses after single or repetitive stimulations of the nucleus ventralis lateralis (VL), n. centrum medianum (CM) and n. ventralis anterior (VA) were observed in 61 cases of parkinsonism, 7 cases of intractable pain and a case of dystonia musculorum deformans from February, 1968 to December, 1969. Experimental studies of the thalamic stimulations with 15 cats were performed as well and the results were compared with that of the human. Evoked responses were analysed with averaging computer technique. Results were as followings. 1) Cortical evoked potentials after single stimulation of the VL nucleus of the human thalamus. a) Evoked potentials appeared on the ipsilateral centro-frontal regions with weaker stimulation in EEG records. However, the evoked potentials showed clear bilateral distribution except the temporal region, predominantly on both centro-frontal regions, with stronger stimulation electroencephalogaphically. b) The evoked potentials of the central site showed clear three negative waves within 200 msec after the stimulation, that is, the first negative wave (T-N) with the peak time of about 10 msec, the second (positive-) negative wave (U-PN) with the peak time of about 50 msec and the third negative wave (V-N) with that of 80-100 msec with averaging computer records. The peak time of the T-N wave and the negative phase of the U-PN wave were nearly constant, but that of the V-N wave considerably varied according to the background activities of EEG. The evoked potentials showed no significant discrepancy between right and left patterns, and moreover, they maintained a similar pattern when the stimulating voltages were changed. c) Bilateral evoked potentials were clearly seen with averaging computer technique even when evoked potentials were small and hardly identified on the contralateral scalp with EEG records. When the stimulating voltages were gradually decreased, the ipsilateral and contralateral evoked potentials disappeared approximately at the same time. d) The latency of the T-N wave was measured to be 5-6 msec with averaging computer records, and the amplitude of the T-N wave increased proportionately with the increase of stimulating voltages.

kn-abstract=Human gall bladders specimens obtained soon after cholecystectomy from 50 patients were observed under electron microscopy. Four types of cells were distinguished by light and electron microscopy in the human gall bladder epithelium, i.e.,"Ordinary epithelial cell", "Clear cell", "Dark cell", and" Basal cell". The Clear cell have been subdivided at least two types by electron microscopy. One was degenerative type and another was immatured one. It was also observed that the mechanism of discharge of secretory granules was the" Merocrine mode". In the cholesterosis, it was assemed that cholesterol was absorbed into the epithelial cells from the bile and accumlated in their basal area, then discharged through their basis. It was taken by phagocytes which gradually transformed into the foamy cells.

kn-abstract=Electrophysiological studies on evoked cortical potentials following ventrolateral (VL) thalamic stimulation of man were performed with averaging computer technique for 41 patients of parkinsonism and other involuntary movement disorders during stereotaxic surgery for last 2 years. 1. Single stimulation of the VL nucleus demonstrated bilateral cortical activity with I-PN (first positive negative), U-PN (second positive negative), V-PN (third positive negative) and W-PN (fourth positive negative) waves. V-P wave was frequently superimposed on negative response between U-N and V-N wave, and W-PN waves were frequently feeble in single stimulation of the VL nucleus. 2. Peak latencies of these waves were estimated 3.4±1.2 msec in T-P, 10.6±1.8 msec in T-N, 29±5 msec in U-P, 55±6 msec in U-N, 71±11 msec in V-P, 90±11 msec in V-N, 115±19 msec in W-P and 160±24 msec in W-N wave in ipsilateral central lead, and 4.0±1.5 msec in T-P, 11.1±2.1 msec in T-N, 31±4 msec in U-P, 57±6 msec in U-N, 74±13 msec in V-P, 92±12 msec in V-N, 118±24 msec in W-P and 156±29 msec in W-N wave in contralateral central lead. 3. The first deflection time of T-P wave, which meant beginning of the evoked response, was 1.5-1.8 msec in stimulated side of central cortex and 2.2-2.9 msec in contralateral central lead, which were obtained in 5 cases precisely measured. 4. The impulse, which provoked T-P N waves, was thought to be conducted from stimulated VL nucleus to the contralateral cortex directly via corpus callosum with 36-43m/sec of velocity. 5. Cortical evoked responses following suprathreshold low frequency stimulation (5-12Hz) of the VL nucleus showed invariably augmenting response and recruiting-like augmenting response. Augmenting response, which consisted of a train of growth in both. positive and negative components, was evoked when each stimulus was given on the descending phase from the peak of V-N or augmented negativiy to the bottom of following positive wave of the preceding response. Analysis of augmentation suggested that synchronization of preceding evoked W-P and present U-P wave would be occured in augmented positivity and synchronization of preceding evoked W-N and present U-N or V-N wave would be occured in augmented negativity. Recruiting-like augmenting response was obtained when each stimulus was given on the ascending phase from the bottom of deep W-P to the following negative wave of the preceding response. Recruiting-like augmentation was shown to be a similar response as augmenting response in the fundamental pattern of averaged evoked activity, although development of negativity and attenuation of positivity caused recruiting-like pattern. Component analysis of recruiting-like augmenting response revealed that predominant development of negativity was thought to be the result of the synchronization of preceding evoked W-N and present U-N or V-N wave. And attenuation of U-P wave was thought to be the result of the desynchronization of preceding W-N and present U-P wave. Responses following lower frequency stimulation with 4Hz or less were similar to responses following single stimulation. Subthreshold stimulation were thought to be difficult to induce any growth of negative cortical response. 6. It was clarified that cortical evoked response following stimulation of the VL nucleus was influenced by components and phases of the preceding cortical response, suggesting that human specific thalamic system would play a possible important role in modulation upon cortical electrical activity.

Reestablished human leukocyte cultures became dually infected with C type and EBV particles and have continuously produced abundant C type particles. These virus particles were nonleukemogenic when inoculated into BALB/c mice but afforded some protection against challenge infection with spleen-derived leukemogenic RLV.

kn-abstract=A clonal lymphoblastoid cell line derived from lymph node of a patient with Hodgkin's diseasewas cultivated in diffusion chambers implanted in the abdominal cavity of mice and cellular morphologic changes were sequentially studied for up to 8 weeks. The majority of cells before intraperitoneal implantation were lymphoblasts with approximately 16% mature lymphocytes. However, after 3 weeks of in vivo cultivation in diffusion chambers, macrophage-like cells began to increase and occupied 80-90% of cells after 4 and 5 weeks. These macrophage-like cells, when tested for phagocytic activity after 4 weeks, exhibited bacterial phagocytosis. Labeling studies with (3)H-thymidine indicated that active DNA synthesis continued for up to 2 weeks of in vivo diffusion chamber cultivation, during which mitotic figures were also observed morphologically. Further, it was attempted to recultivate in vitro cells that were taken out of diffusion chambers after 2, 3, and 4 weeks of in vivo implantation. These 3 separate attempts led to the development of lymphoblastoid cells that were morphologically and cytogenetically similar to those prior to diffusion chamber implantation. From these findings, it is suggested that human lymphoid cells undergo morphologic alteration to macrophages under certain circumstances.

kn-abstract=Three types of investigations by the immunofluorescence method were performed. Antibody to EB virus (EBV) in various sera and EBV antigen in the nine lymphoblastoid cell lines were tested by the indirect method and production of immunoglobulin in these cell lines was by the direct method. 1) It has been shown that the virus is widely disseminated among normal persons in Japan. 2) Newborn infants possess EBV antibody on delivery. This antibody is probably transmitted from mother to fetus via the placenta. 3) There is no difference in EBV antibody titers between normal individuals and donors from whom the lymphoblastoid cell lines were established. 4) EBV antigen appears in a small number of lymphocytes and macrophages within a few weeks after initiation of peripheral leukocyte cultures. 5) All the established cell lines persistly demonstrate a few percentage of EBV antigen-positive cells. 6 ) All the cell lines produce two or three classes of immunoglobulin but the proportion of the stained cells varies considerably during long-term culture.

kn-abstract=Nine new lymphoblastoid cell lines have been established from peripheral blood leukocytes of patients with infectious mononucleosis, subacute myelo-optico-neuropathy (SMON), acute myelogenous leukemia and chronic lymphatic leukemia. All the cell lines grow in suspension and mostly consist of lymphoblastoid cells regardless of the cell source and clinical status of the donors. A few percentage of Epstein-Barr virus (EBV) antigen-positive cells were detected by the immunofluorescence method in all the cell lines. These cell lines have maintained karyotypes of predominantly normal diploid modes. It is suggested that the origin of these cell lines may be certain lymphocytes in peripheral leukocytes. From the present study, a following hypothesis may be offered on the establishment of the lymphoblastoid cell lines. It is conceivable that EBV which is harbored in vivo in lymphocytes might be activated and replicate in the early stage of leukocyte culture. The virus would, thereafter, exert an antigenic stimulation on some of the lymphocytes and consequently they would undergo blastoid transformation, yielding self-sustaining cell lines.

kn-abstract=Normal and pathological antral mucosa (gastric ulcer, gastroduodenal ulcer, duodenal ulcer, gastric cancer, giant rugae, gastritis chronica and gastric polyp) were examined histochemically and electron microscopically. 1) It was clarified that the Ec-cells are observed only in the mucosa with intestinal metaplasia, and never in the normal mucosa. We tentatively classified the Ec-cells into two types; Ec-T-cell and Ec-U-cell. The specific granules in the Ec-T-cells are polymorphous and contain a dense core enclosed by a limiting membrane which fits either tightly or loosely. The Ec-U-cells have electron dense and polymorphous granules but do not contain a dense core in the limiting membrane. The ratio of Ec-T-cells to Ec-U-cells in the antral mucosa with intestinal metaplasia seems to be almost equal in gastric ulcer but smaller in gastric cancer. 2) Cell type W-cell in the normal antral mucosa has three kinds of granules; electron dense granules (100-200 mμ in diameter), granules (about 400 mμ in diameter) which have cloud-like or bubble-like substances in the limiting membrane, and granules which are empty-looking in the limiting membrane. In gastric ulcer cases, the W-type cells were apt to be granulated but there were no increse in the number. On the contrary, in atrophic gastritis, the W-type cells had low electron dense granules which were empty-looking in the limiting membrane.

kn-abstract=The endocrine cells in te normal antral mucosa of the human stomach were examined by the electron microscope. According to their fine structural characteristics, they were classified into the following five types. 1) Cell-type U is triangular in shape. The granules are round and vary in diameter (300-600mμ) and in electron density. 2) Cell-type V is triangular in form and has many grnules (130mμ in diameter) with high electron density. These granules are characterized by their uniform size and homogeneous appearance. 3) Cell-type W contains a prominent endoplasmic reticulum in the supranuclear region. These kinds of granules are recognizable in the basal part: smaller ones (100-200mμ), which are dense, larger ones (400mμ) which are pale and another larger ones (400mμ) which are empty-looking. 4) Cell-type Xis contact with the glandular lumen and contains numerous secretory granules with various densities. 5) Cell-type Y is oval in shape and characterized by small granules (100-150mμ) with moderate density, localized in the basal region. This cell type seems to have some features of an immature endocrine cells.

kn-abstract=Spindle-like afterdischarges evoked by stimulation of ventrolateral thalamic nucleus and spontaneous spindle waves were analized to investigate the electrophysiological mechanism of cortical synchronized activities in man as well as in cat. In man, three positive and three negative waves, namely T-P, T-N, U-P, U-N, V-P and V-N, were observed as cortical evoked responses after single stimulation of the ventrolateral thalamic nucleus. And W-P and W-N were observed after the stronger stimulation which could provoke augmenting response with the repetitive volley. Later components of evoked cortical responses were investigated in cat immobilized under local anesthasia. Recording electrole was located on the anterior sigmoid gyrus. As the intensity of the thalamic stimulation was increased, afterdischarges of the negative waves, which appeared with long latency (about 200 msec.), increased in number and developed into spindle-like pattern with notches on afterdischarges. The long latencied negative wave in cat and W-N in man were considered to correspond to Lehtinen's "precursor of the evoked spindle activity". It has been already reported by Miyamoto that W-N was supposed to play an important role in augmenting response in man. Close relationship was indicated between augmenting response and spindle-like afterdischarges. Futhermore, the similarities of the pattern between spindle-like afterdischarges following thalamic stimulation and spontaneous spindle waves in cat, and attenuation of ipsilateral spontaneous spindle waves after destruction of the ventrolateral thalamic nucleus in cat as well as in man were also observed. From these facts these cortical synchronized activities, namely AR, spindle-like afterdischarges and spontaneous spindle waves were considered to be brought by similar neuronal mechanism with some varieties of synchronization ascribed to arousal levels under influences of activities of the ventrolateral thalamic nucleus. On the other hand, spindle-like afterdischarges and spontaneous spindle waves in cat were analized for investigating their waxing and waning phenomena. Notches were observed on each waves. When the wave grew with maximal amplilude in a train of spindle, the notch of the wave became obscure. The phenomenon was considered that the notch was synchronized with the wave, forming maximal amplilude of the wave in a train of spindle. In other words, mechanism of this phenomenon was supposed to be explained as a beat of two rhythmic activities slightly different in frequency.

kn-abstract=Sensitized lymphocytes have been demonstrated to inhibit tumor growth in vivo systems. In SV40-viral oncogenesis, some specified immunization with virns and with virus-induced tumors to the animals results in rejection of further transplantation of the tumor cells. To analyze these phenomena by our specially devised cytotoxicity test, the authors have studied cell mediated immunity for tumor specific transplantation antigen (TSTA) in SV40 viral oncogenesis. The results suggest that sensitized lymphocytes inhibit the growth of heterogenic SV40-transformed target cells as well as syngenic ones. And the lymphocytes from tumor-bearing animals have lower ability of the inhibition on the target cells, which may be explained that the lymphocytes in tumor bearing animals are under the condition of immunologically insufficient state.

kn-abstract=In the human thoracic duct wall the direction and the ascending angle of the smooth muscle cells are not necessarily fixed according to the site, but as a rule the smooth muscle cells of the interior layer of the tunica media ascend longitudinally at about 80° with their origin at the internal elastic membrane and connect to the circular muscle of tunica media that ascends at angle of about 10° and terminates at the external elastic membrane. At the exterior side of tunica media it becomes often longitudinal and sometimes it forms the exterior layer. The smooth muscle cells which connect the middle layer and exterior layer from the interior layer run in a specific arc line. In the case where a pair of valves cover the thoracic wall, at the site between the two valves there can be observed no longitudinal muscle of the interior layer. Generally the internal elastic membrane is incomplete, and often it forms longitudinal networks, but there is sometimes the case where morphologically it forms a well arranged internal elastic membrane.

en-abstract=In an attempt to evaluate the significance of mononuclear cells in the experimental allergic hepatitis which was previously studied, lymphocytes from inbred strain C(57) BL mice with the hepatitis was passively transfered into x-ray irradiated isologous mice. Early histological changes in the liver of the recipient mice consisted of an extensive coagulation necrosis on the 2nd or 3rd day after the transfer, and delayed changes occurring on the 7th to 10th post-transfer day included a marked infiltration of mononuclear cells in the portal areas, various types of liver cell necrosis and degeneration, a mononuclear cell infiltration in the sinusoid as well as an activation of the Kupffer cells as compared with control groups. These histological changes, however, were transient and subsided in 2 to 3 weeks post to the transfer of the cells. There was no tendency to the development of a feature of chronic hepatitis. The present experiment indicated that the passive transfer of sensitized lymphocytes obtained from mice with the experimental allergic hepatitis made by the previous experiment produced an allergic hepatitis comprising a coagulation necrosis and others in isologous mice, but this hepatitic change was transient and by no means transformed to a chronic status similar to a human chronic hepatitis as in the previous experiment.

en-abstract=In an attempt to evaluate histologically an allergic phenomenon involved in the development of chronic hepatitis in man, the inbred strain C57BL mice were sensitized for prolonged durations from 5 to 19 weeks with a homologous liver extract from AKR mice as well as with complete Freund's adjuvant. Histological changes in the liver of the sensitized mice immediately after the treatment comprised a marked round cell infiltration in the portal areas, piece-meal necrosis, various types of liver cell necrosis and degeneration, and an activation of the Kupffer cells as compared with control groups. These histological changes somewhat resembled the findings of chronic hepatitis in human liver disease, but they have greatly subsided in 5 weeks post to the last sensitization. It may be assumed on the basis of the present experiment that a persistent sensitization for a longer duration is necessitated for the establishment of a chronic murine hepatitis similar to a human chronic hepatitis.
kn-abstract=ヒトのウイルス性肝炎の発症および慢性化のアレルギー性機序を解明するための一手段として, AKR肝抽出液を抗原としてC57Blに長期感作を施行し,肝グリソン氏鞘内に著明な円形細胞浸潤,piecemeal necrosis,肝細胞壊死,星細胞の反応を作成しえたが,リンパ?胞の形成,肝グリソン氏鞘の結合織の増生は認められなかった.以上の組織変化は肝炎B抗原,すなわち, hetero抗原とその抗体とのアレルギー機序によって生じると考えられるヒトのウイルス性肝炎の組織表現にかなり類似している.しかし,長期感作を中止し放置すると,組織変化は消褪した.

kn-abstract=An Epstein-Barr virus (EBV) -positive human lymphoblastoid cell line chronically infected with Rauscher murine leukemia virus (RLV) was transplanted into antilymphocyte serum (ALS)- treated newborn hamsters. Four of 10 hamsters transplanted developed nonlethal regressive tumors which continued to shed C-type virus. Lymphoblastoid cell cultures reestablished from the heterotransplanted tumor cells were positive for both EBV capsid and murine gs-1 antigens. In contrast, all the hamsters transplanted with its parent cell line without RLV infection succumbed to lethal progressive tumors. The RLV-infected cells were shown to have cell surface antigen that was not found in the noninfected cells. It is postulated that new membrane antigen associated with C-type virus infection provoked more immunologic reaction even in ALS-treated hamsters, accounting for the reduced tumorigenicity of the RLV-infected human leukocytes.

kn-abstract=An EB virus-carrying lymphoblastoid cell line established from peripheral blood of a patient with SMON was super-infected in vitro with murine Rauscher leukemia virus. Since then, the cell line has been dually infected with both viruses for more than 1.5 years, as repeatedly demonstrated by the presence of herpes type virus particles and C type virus particles. The C type virus particles liberated from the human cultured leukocytes were no longer leukemogenic when inoculated into otherwise susceptible BALB/c mice, but this procedure rendered them considerably resistant to challenge infection with leukemogenic Rauscher leukemia virus that had been maintained by passage through BALB/c mice. The infectivity of the human cell-derived C type virus to other lymphoblastoid cell lines established from different patients and to primary BALB/c mouse embryo cells could not be demonstrated by the method employed. The implication of these findings is discussed in the light of possible viral etiology of human malignancy.

kn-abstract=In the previous report, we dealt with the method and the culture of human embryonic liver cells, and its difficulties in establishing epithelial cell lines from normal human liver. HuL-4 cell strain was published as an epithelial cell strain in the previous paper. We examined the cell morphologically, histochemically, and the cellular localisation of albumin and AFP (α-fetoprotein) immunofluorescently. Chromosome of the cells and uptake of Indian ink into the cell were also undertaken. We also calculated the growth curve of the strain and analyzed the liver specific enzymes. The results are summarized as follows. 1). HuL-4 cell strain derived from human embryonic liver disclosed dominant epithelial cell growth than fibroblastic cells, and it continued to cultivate up to 24 passages in 758 days. 2). Direct immunofluorescence method for albumin and AFP failed to show any positive stain. 3). PAS staining of the cell revealed weak positive, and it was digested by diastase. PAP silver staining was negative, and the uptake of Indian ink into the cells was negative for up to 12 hours. 4). Chromosome analysis of the cell was normal (46 numbers, diploid) and no marker chromosomes were detected. 5). Hul-4 cell strain was epithelial morphologically, but it contained no liver specific enzymes.

kn-abstract=Glycolytic enzyme activities of human breast cancer was studied on age, menopausal status, T, N, Stage and pathology in benign and malignant tumor. Influences on incubation with additional hormones also were studied. Mastopathy, benign tumor and breast cancer showed varied enzymic activity. High enzymic activity was observed in breast cancer tissue, but the enzymic activity was not paralleled with tumor size. Enzymic activity changed by incubation with additional hormones. Pre menopausal state, T(1), negative lymph node metastasis, Stage I tissues were elevated enzymic activity. Post menopausal state, T(3), positive lymph node metastasis, and Stage III tissues were decreased enzymic activity.

kn-abstract=Thirty-six cases of human atrophic chronic gastritis were observed by transmission and scanning electron microscope. Generally, in the surface and neck mucous cells, vacuole formations and swelling of mitochondria were occasionally observed. Although, increase of young parietal cells were frequently noted, ultrastructural changes were hardly seen in the cytoplasm and the nucleus of both the parietal cells and the chief cells. Intestinal metaplastic mucosa was found in almost all cases of antral mucosa and in half cases of corporal mucosa of chronic gastritis. In the SEM observation, the gastric mucosa and the intestinal metaplastic mucosa were clearly bordered. In TEM observations, all types of normal small intestinal cells were found in the intestinal metaplastic mucosa, and there were no ultrastructural differences between normal intestinal cells and intestinal metaplastic mucosa cells. It was interesting that enterochromaffin cells, which were scarce in normal gastric mucosa and numerous in small intestine, were frequently observed in intestinal metaplastic mucosa. In the three cases of chronic gastritis, the peculiar type cells which had both endocrine cells granules and mucous granules were found and their origins were discussed.

kn-abstract=Using horseradish peroxidase (HRP) which serves as its own tracers, the absorption of intact macromolecules through the human gastrointestinal tracts was observed. In healthy volunteers, HRP was poured into the stomach, the duodenum, and the ileum through the gastric, duodenal and colonofiberscopes at several days interval. Twenty minutes after the injection, small samples of mucosa were removed. The tissues thus obtained were treated in the manner of Karnovsky and embedded in Epon and observed under an electron microscope. The absorption of HRP through the human small intestine and the intestinal metaplastic epithelia of the stomach was clearly demonstrated. Moreover, in intestinalized epithelium of the stomach, HRP was absorbed and transferred into the capillary lumen. These results indicated the posibility of absorption of macromolecules through the human gastrointestinal tract, which may be a cause of food-allergy and food poisoning. At the same time, it showed the effectiveness of oral administration of some enzyme-containing medicines. The absorption through the intestinal metaplastic epithelium was considered to be especially significant, because eaten proteins are promptly absorbed before digestion occurred.

en-abstract=
kn-abstract=Firstly, the ultrastructure of the caveolated cells on the rat bile duct were examined by a transmission and a scanning electron microscope. Next, the author seeked whether caveolated cells were present or not in the human digestive organs. Lastly, functional study of the caveolated cells on the rat bile duct were investigated using horseradish peroxidase and pilocarpine. Then the facts mentioned below were clarified. 1) Caveolated cells in the rat bile duct were found most densely at the divelticulum-like recesses but on the luminal surface except this recesses caveolated cells were found partly densely and partly sparsely. 2) On the rat, the straight filaments of the caveolated cells of the bile duct were less developed than that of the digestive tract, but circular filaments were more developed than that of the digestive tract. 3) The apical vesicles of the caveolated cells were revealed to have no communication to outer lumen of these cells using lanthanum as a tracer. 4) The caveolated cell-like cells were found in the mucosa of a human colon. But these cells could not be identified clearly with caveolated cells. Because the vesicles were scanty and small in size and the inner substance was relatively electron opaque. 5) After intraluminal injection of peroxidase into ligated segments of bile duct, the marker was found within the apical vesicles. But it was not uncertain whether pre-existing apical vesicles had taken up the marker or vesicles containing the marker were formed newly by pinocytosis. 6) After intraperitoneal injection of pilocarpine, the supranuclear vesicles began to expand and the vesicles with granules moved toward the free surface suggesting eruption or diacrine secretion. And frequently apocrine secretion was also observed. In conclusion, the author supposes that caveolated cell may have both absorptive and secretory functions and this type cells may present in human digestive tract.

kn-abstract=The lymphocyte subpopulations were detected in the target organs obtained from various autoimmune disorders on the tissue cryosections. Thymus-derived lymphocytes (T cells) and bone marrow-derived lymphocytes (B cells) were detected by rosette formation with sheep erythrocytes (E) or with sheep erythrocytes coated with antibody and complement (EAC) respectively. Almost all infiltrating lymphocytes in the salivery glands in patients with Sjogren's syndrome were identified as B cells and T cells were detected only along the ducts. In Hashimoto's thyroiditis, infiltrating lymphocytes with the lymph follicles in the thyroid gland were mostly B cells whereas T cells localized as surrounded the thyroid follicles. T cells would not be detected in the spleen sections obtained from the patients with hypoplastic anemia at all. The white pulp was constituted by B cells, and the mononuclear cells in the red pulp might be macrophages of which these cell surfaces had IgG-Fc receptors. The lymph follicles of the thymus in a patient with myasthenia gravis complicated with thymoma was demonstrated to be formed with B cells. Therefore, it could be concluded that B cells were predominant lymphocytes in the target organs, while T cells localized in situ developing the autoimmune reactions in various autoimmune diseases.

kn-abstract=Thymus-derived lymphocytes (T-cells) and bone marrow-derived lymphocytes (B-cells) in the cryosection of human tissues were identified either by rosette formation with sheep erythrocytes (E) or with erythrocytes sensitized with antibody and complement (EAC), respectively. Invariable and stable reaction was obtained in EAC rosettes of the tissue lymphocytes while E binding of them was rather unstable. E could be adhered in the thymus sections which were obtained from normal infants during open heart surgery, but EAC did not bind to them at all. It was confirmed that B-cells located mostly in the lymph follicles of the lymph nodes as well as the palatine tonsils and T-cells were present predominantly in the paracortical area and interfollicular region. B-cells in the germinal centers would generally have more activated C(3) receptors than those of the mantle zones. In addition, B-cells of the lymph follicles both in the lymph nodes and in the palatine tonsils could be also detected utilizing the membrane immunofluorescence technique. The proportion of T and B-cells distribution in the lymphoid tissue was well correlated with that obtained on free cell suspension technique.Therefore, it could be concluded that T and B lymphocytes were able to identify respectively even in tissue level.

kn-abstract=Absolute peripheral blood monocyte counts and the β-galactosidase activity of monocytes were studied in 60 patients with lung cancer, 20 with malignant lymphoma, 17 with other malignant diseases, 13 with sarcoidosis and 28 normal individuals. The monocyte count was 296.3±176.8/cmm in lung cancer, 315.6±160.0/cmm in malignant lymphoma, 217.8±89.6/cmm in sarcoidosis, and 298.6±144.1/cmm in normal individuals. Although there was no significant differences in the monocyte count of malignant and non-malignant diseases, all patients with lung cancer or malignant lymphoma had monocyte counts less than 100/cmm. In patients with lung cancer and malignant lymphoma, there was no significant differences in histological types or clinical stages. The monocyte count in lung cancer patients treated with streptococcal agent OK-432 was elevated to 484.9±269.0/cmm, as compared with 315.5±107.7/cmm before administration. A nadir of monocyte counts was found at one week after combination chemotherapy but recovery to normal value was observed by 3 weeks after. On the other hand, white blood cell counts reached a nadir 2 weeks after chemotherapy and recovered by 4 weeks after. The percentages of β-galactosidase positive monocytes were 21.5±11.5% in patients with lung cancer, 20.1±7.5% in malignant lymphomas, 19.1±6.8% in other malignant diseases and 25.3±12.4% in normal individuals. There was no significant differences in β-galactosidase activity related to histological types or clinical stages of patients with lung cancer and malignant lymphoma. No changes in β-galactosidase activity were found between before and after combination chemotherapy.

kn-abstract=The isolation of monocytes in human peripheral blood by discontinuous density gradients was studied. Discontinuous density gradients were obtained by successive layering of bovine serum albumins into three layers in 10ml glass tubes. Buffy coat cells were layered on top of a gradient and centrifuged under various conditions of centrifugation. Optimal isolation was achieved by centrifugation on a three layer of 35-32-28% bovine serum albumin at 490g for 60 minutes. The purity, yield and recovery of monocytes at the interface between 35% and 32% bovine serum albumin were 54.0%, 7.0×10(5) and 22.0% respectively. After centrifugation on Conray-Ficoll mixtures, the interface fraction containing lymphocytes was removed and the bottom fraction containing monocytes and other cells was centrifuged under various condition. The optimal condition was on a three layer of 35-32-28% bovine serum albumin at 400g for 40 minutes. The purity of monocytes by this method increased to 75% but the yield and recovery declined to 2.5×10(5) and 4.5% respectively. From these data I concluded that isolation of monocytes from blood only on density gradients was difficult because of a partial overlap between monocytes and lymphocytes in the density distribution profiles.

kn-abstract=A newly developed collagenase assay method using (14)C-labeled soluble collagen as substrate has been applied to the determination of collagenase activity in human leucocytes and synovial fluids. The results indicated that collagenase activity in the both samples could be measured by this method as observed with tadpole collagenase, except that 35 % dioxane was preferable for the extraction of the enzyme digestion products in the case of synovial fluids. Collagenase activity determined by the present method was well correlated with that obtained by the conventional assay method using reconstituted collagen fiblils as substrate (r=0.963 and 0.829 (p<0.01) respectively). In preliminary experiments with leucocytes from patients with diabetes mellitus (DM), systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), it was observed that collagenase activity in leucocytes increased significantly in SLE and from some patients with RA, while no appreciable differences were observed in diabetics, compared to that in normals. In synovial fluids from patients with RA and osteoarthritis (OA), the accumulation of large amount of inactive (latent) form of collagenase was demonstrated by the treatment of synovial fluids with 3M KI. And it was varied significantly in one patient at different time while no appreciable amount of the active form was observed during the period.

kn-abstract=Tyramine and octopamine were identified by means of mass fragmentography in human serum. The peaks identical to the retention time of tyramine and octopamine were found on gaschromatogram obtained from serum sample. Two fragments, M/e 316 and M/e 303 in mass spectrum of tyramine were used in tyramine identification, and M/e 528 and M/e 515 were used in octopamine identification. As the experimental results, the ratio M/e 303 : M/e 316 of the sample was identical to that of authentic tyramine, and ratio M/e 515 : M/e 528 was identical to that of authentic octopamine. These results suggest that tyramine and octopamine could exist in human serum.
