抄録 The sensitivity and specificity of magnified endoscopic features for differentiating follicular lymphoma from other diseases with duodenal whitish lesions have never been investigated. Here we compared the magnified endoscopic features of duodenal follicular lymphoma with those of other whitish lesions. We retrospectively reviewed the cases of patients with follicular lymphoma (n=9), lymphangiectasia (n=7), adenoma (n=10), duodenitis (n=4), erosion (n=1), lymphangioma (n=1), and hyperplastic polyp (n=1). The magnified features of the nine follicular lymphomas included enlarged villi (n=8), dilated microvessels (n=5), and opaque white spots of various sizes (n=9). The lymphangiectasias showed enlarged villi, dilated microvessels, and white spots, but the sizes of the white spots were relatively homogeneous and their margin was clear. Observation of the adenoma and duodenitis revealed only whitish villi. Although the lymphangioma was indistinguishable from the follicular lymphomas by magnified features, it was easily diagnosed based on the macroscopic morphology. In conclusion, magnified endoscopic features, in combination with macroscopic features, are useful for differentiating follicular lymphomas from other duodenal diseases presenting whitish lesions.

抄録 We present a case of a 67-year-old Japanese man with a serious oropharyngeal ulceration that at first seemed to be destructive malignant lymphoma or oropharyngeal carcinoma. We suspected methotrexate (MTX)-associated lymphoproliferative disorder (LPD) induced by MTX treatment for rheumatoid arthritis (RA). About 3 weeks after simple discontinuation of MTX, complete regression of the disease was observed, confirming our diagnosis.

抄録 <p>Southern blot hybridization was used to detect the rearrangement and amplification of five proto-oncogenes (bcl-2, bcl-1, c-myc, c-myb and c-Ha-ras) and one tumor suppressor gene (RB-1) in 55 Japanese patients with non-Hodgkin's lymphoma; 16 with T-cell lymphomas and 39 with B-cell lymphomas (7 follicular and 32 diffuse lymphomas). Genetic abnormalities of the proto-oncogenes were detected in 7 of the 55 (13%). Genetic abnormalities of bcl-2 plus other genes were detected in 5 of 7 cases of follicular lymphoma (71%), rearrangements of bcl-2 and c-myc, rearrangement of bcl-2 and amplification of c-myb. Genetic abnormalities were observed in only three cases of diffuse lymphoma. In each of 3 cases of B-cell lymphoma, one of the genes, blc-2 mbr, bcl-2 mcr and c-myc, was rearranged respectively. The incidence of genetic abnormalities in diffuse lymphomas (6.3%) was lower than that in follicular lymphomas. None of diffuse lymphomas had double oncogene abnormality. No abnormalities were found in RB-1, bcl-1, and Ha-ras. These findings suggest that follicular lymphomas are associated with some abnormalities of oncogenes not restricted to bcl-2 that facilitate growth which may be associated with their clinical features.</p>

抄録 <p>A cell line of human lung large cell carcinoma (LCC) was established directly from the metastatic skin tumor tissue. The clinical course of the patient who carried this carcinoma was peculiar; generalized lymphadenopathy, histologically resembling Hodgkin's disease, was found as the first clinical symptom. The lung tumor was not discovered until the time of autopsy. This cell line (KaMi) grew adherent to culture vessels with the population doubling time of 20.6h, formed colonies in soft agars with efficiency of 22.6%, and formed tumors in athymic nude mice. The authenticity of KaMi was confirmed by chromosomal analysis and isoenzyme patterns. KaMi cells bore a strong resemblance to the original tumor cells which were composed of small spindle cells, large polygonal cells, and multinucleated giant cells. Immunohistochemically, KaMi cells showed a weak tendency to differentiate to squamous cells, and these immunohistochemical reactivities were almost compatible to those of the original tumor cells, but ultrastructurally, KaMi cells were more immature than the original ones. Treatment with several reagents could not augment a differentiation of KaMi cells. Cytokeratin profiles showed a tendency of squamous cell differentiation. KaMi cells may aid in elucidating the pathogenesis and biology of LCC and its relationship to other lung tumors. </p>

抄録 <p>It has been reported that Epstein-Barr virus (EBV) resides in resting B cells in vivo. However, an ideal in vitro system for studying EBV latent infection in vivo has not yet been established. In this study, a mantle cell lymphoma line, SP53, was successfully infected with a recombinant EBV containing a neomycin-resistant gene. The EBV-carrying SP53 cells were obtained by selection using G418. They expressed EBER-1, EBNAs, and LMP1; this expression pattern of the EBV genes was similar to that in a lymphoblastoid cell line (LCL). However, proliferation assay showed that the EBV-carrying SP53 cells have a doubling time of 73 h, compared with 57 h of SP53 cells. Transplantation of 10(8) SP53 cells to nude mice formed tumors in 4 of 10 mice inoculated, but the EBV-carrying SP53 cells did not. Unexpectedly, EBV infection reduced the proliferation and tumorigenicity of SP53 cells. However, the EBV-carrying SP53 cells showed higher resistance to apoptosis induced by serum starvation than did the SP53 cells. The inhibition of proliferation and the resistance to apoptosis induced in SP53 cells by EBV infection indicate that this cell line might to some extent provide a model of in vivo EBV reservoir cells.</p>

抄録 <p>A monoclonal antibody (MAb), OPT1, reactive with T cells in formalin-fixed, paraffin-embedded tissue sections, has been identified through immunization with activated T cells from peripheral blood lymphocytes (PBL). The antibody is an IgG1 antibody as demonstrated by the Ouchterlony technique. By cytofluorometric analysis, almost all CD3+ lymphocytes and only a few CD20+ lymphocytes of peripheral blood expressed the OPT1 antigen. Nonhematolymphoid cell lines were negative for OPT1 by the immunoperoxidase staining using acetone-fixed cell lines. On the contrary, peripheral T cells, cells of two T cell lines out of four and a part of the cells of one B cell line out of two were positive for OPT1. The immunoperoxidase staining of paraffin-embedded tissue sections revealed that most of lymphocytes in T cell areas of lymph nodes expressed OPT1 antigen. Some lymphocytes in both cortex and medulla of the thymus and erythroid precursors of the bone marrow were OPT1+. In the malignant lymphoma series, approximately 90% of T cell lymphomas and 6% of B cell lymphomas reacted with OPT1. None of the Reed-Sternberg cells nor Hodgkin cells in Hodgkin's disease were positive. Consequently, OPT1 may be useful for the diagnosis and study of malignant lymphomas and other related lesions.&#60;/P&#62;</p>

抄録 <p>A 46-year-old woman with acromegaly and hyperthyroidism due to a pituitary adenoma. She had high serum thyroid-stimulating hormone (TSH) levels and very high serum growth hormone (GH) levels. Transsphenoidal removal of the tumor, post-operative irradiation, frontal craniotomy for removal of residual tumor and large-dose bromocriptine therapy were carried out consecutively. After therapy, serum GH levels gradually decreased, but not to the normal range, and serum TSH levels remained at inappropriately normal levels. Using immunoperoxidase techniques, GH-, TSH- and follicle-stimulating hormone (FSH)-containing cells were demonstrated in the adenoma. A long-acting somatostatin analogue (SMS 201-995, 600 micrograms/day) suppressed the serum GH level to the normal range with a concomitant suppression of TSH. Furthermore, the paradoxical serum GH responses to TRH and LH-RH were slightly improved. No important subjective side-effects were noted. Therefore, SMS 201-995 appeared to be a very effective drug in this patient with a GH- and TSH-producing pituitary tumor.&#60;/P&#62;</p>

抄録 <p>Epstein-Barr virus (EBV)-related herpesvirus (Si-IIA-EBV) was serially transmitted for 3 passages from rabbit to rabbit of the opposite sex by blood transfusion, which subsequently induced virus-associated rabbit lymphomas. The virus could be transmitted by transfusion with 15-20 ml of whole blood (7/7) or irradiated blood (1/6) from the EBV-related virus-infected rabbits, but there was no transmission with transfusion of cell-free plasma (0/6) from the infected rabbits. Passive anti-EBV-VCA IgG (x 20 approximately x 10) titers decreased during the first 1-2 weeks in the transfused rabbits. The virus-transmitted rabbits showed a gradual increase in antibody titers ranging from peak titers of x 640 to x 2560 after 3 weeks of transfusion. The recipient origin of malignant lymphoma that developed in the first rabbit transfused by infected blood was confirmed by chromosomal analysis. This rabbit model thus shows that EBV-related herpesvirus is serially transmissible by blood transfusion and that transmission can not be completely prevented by irradiation of blood, but removal of blood cells is the best way to prevent transmission of EBV-related virus. Therefore, this animal model provides a convenient in vivo system for studies of the prevention and therapy of transfusion-related transmission of EBV and EBV-associated lymphoproliferative diseases in immunocompromised human beings.</p>

抄録 <p>FKHRL1 (FOXO3a), a member of the Forkhead family of genes, has been considered to be involved in the development of breast tumors; however, the in vivo expression and activation status of FKHRL1 in breast tumors still remains unclear. We immunohistochemically demonstrated the expression and intracellular localization of FKHRL1 in human breast tumors by the novel anti-FKHRL1 antibody which is available for formalin-fixed paraffin-embedded specimens. In a total of 51 cases of benign tumors, FKHRL1 was diffusely expressed in all cases, and its intracellular localization was revealed to be cytoplasmic (inactive form) in 94% of cases of intraductal papillomas (16/17) and 91% cases of fibroadenomas (31/34), with a similar pattern to normal glandular epithelium. In invasive ductal carcinomas, 83% of the cases (93/112) diffusely expressed FKHRL1; however, unlike benign tumors, 71% of the cases (66/93) showed the nuclear-targeted, active form of FKHRL1. Moreover, activated FKHRL1 was predominantly observed in scirrhous (29/36, 81% of the cases) and papillotubular (30/38, 79% of the cases) subtypes, compared to the solid-tubular subtype (7/19, 37% of the cases). Furthermore, the cases with nuclear-targeted FKHRL1 showed a tendency to have lymph nodal metastasis with statistical significance (P < 0.0001). Thus, the activation of FKHRL1 seems to be recognized as one of the specific features of invasive ductal carcinoma of the breast.</p>
