To clarify the immunological function of 'M' (microfold or membranous) cells in the large intestine, we examined the expression of intercellular adhesion molecule-1 (ICAM-1) and HLA-class II antigens immunohistochemically in M cells and follicle-associated epithelia (FAE) covering isolated lymphoid follicles of the human colon in comparison with their expression in Peyer's patches of the small intestine. In Peyer's patches of the small intestine, ICAM-1 was not expressed on the epithelial cells covering the lymphoid follicles, but their cell surfaces were stained positively for HLA-DR. In contrast, colonic M cells expressed ICAM-1 on their cell surfaces but were negative for HLA class II antigens. By immunoelectron microscopy, ICAM-1 was seen to be distributed on the surface of microfolds, on the membranes of apical vesicles and on part of the basolateral plasma membranes of M cells, but was not expressed on adjacent FAE. These findings imply that the M cells in the colon and in Peyer's patches have different immunological roles. In addition, identification of ICAM-1 expression on the colonic M cells should help elucidate the pathogenesis of some inflammatory colonic diseases which appear to start in the lymphoid follicles of the colonic mucosa.

The low mass iron was detected by the bleomycin assay. Fifty-one blood samples were analyzed (from 28 males and 23 females). High "free" iron was detected in 47 sera samples from thalassemia patients. Serum ferritin, which reflects the body store iron, was higher than the normal range (10-200 ng/ml) in 49 patients. On the other hand, serum iron of 39 sera samples fell within the normal range (50-150 micrograms/dl). Four were less than 50 micrograms/dl and eight were more than 150 micrograms/dl. Almost all the patients' sera of normal or higher serum iron level contained "free" iron. Thus, almost all the sera from thalassemic patients from Myanmar contain bleomycin-detectable iron, even when serum iron is within the normal range. In developing countries where undernutrition is prevalent (serum albumin in these patients was 3.6 +/- 0.4 g/dl, P < 0.0001 vs. control value of 4.0 - 4.8 g/dl), normal serum iron does not preclude the presence of free iron in the serum.

Compared with blood donors having abnormal levels of alanine aminotransferase (ALT), sera from the donors with normal levels of ALT reacted less frequently against NS4 antigens (anti-5-1-1: 34.4% vs. 54.5%, P = 0.0609; anti-c100-3: 34.4% vs. 56.1%, P < 0.05). Also the positivity for antibodies against these antigens were more frequent in sera from donors with genotype 1b HCV-RNA than other genotypes (anti-5-1-1: 61.0% vs. 23.5%, P < 0.01; anti-c 100-3: 61.0% vs. 26.5%, P < 0.01). The prevalence of each genotype in blood donors with normal ALT levels was different from that in patients with advanced liver disease (P < 0.05), genotype 1b being less and genotype 2a being more frequent. The number of HCV-RNA copies/0.5 ml in donors with normal ALT was 10(7.9 +/- 1.0) (n = 27) and that in patients with chronic liver disease was 10(7.4 +/- 0.8) (n = 116), the difference being statistically significant (P < 0.05). In conclusion, the results of this study suggest that asymptomatic blood donors carrying HCV have the serological and virological characteristics different from the patients with advanced liver disease.

The push-up was carried out using 3 hand positions (fist, finger and palm) and a push-up device. In all hand positions, anteroposterior force (Fx) and the mediolateral force (Fy) appeared after the vertical force (Fz). The end point of Fx and Fy was observed before that of Fz. Among the 4 different hand positions, Fx and Fy appeared first in the palm, followed by the finger and fist positions, and lastly in the push-up devices. The results indicate that the more unstable pushing-up the body is, the earlier and longer Fx and Fy are. Thus, Fx and Fy are considered to be good indicators of body balance during the push-up motion. The elbow joint showed a hyperextended position only when using the palm position in the maintenance phase. The wrist joint showed palmar flexion only when using the fist position.

In an attempt to reduce the incidence of graft failure, the feasibility of pretransplant assessment of graft viability was investigated by 31P nuclear magnetic resonance (NMR) spectroscopy. The level of adenosine triphosphate (ATP) was measured as an indicator of liver function by 31P NMR spectroscopy after a 30 min normothermic reperfusion following cold-storage in University of Wisconsin (UW) solution. The mean +/- SD beta-ATP/Pi ratio after preservation for 0, 12, 24 or 48 h was 1.40 +/- 0.34, 0.85 +/- 0.27, 0.64 +/- 0.14 and 0.38 +/- 0.09, respectively. Significance was observed between 12h and 24h and between 12h and 48h of preservation. These results correlated well with the morphological changes in endothelial cells and sinusoidal lining cells examined by transmission electron microscopy. It is suggested strongly that microcirculatory disturbances due to endothelial cell injury impairs the recovery of ATP levels after reperfusion, and that ATP determination by 31P NMR spectroscopy, as a non-invasive modality, may help in the prediction of PNF after liver transplantation.

HPV DNA, either type 16 or 18, was detected by polymerase chain reaction, and by Southern blot hybridization in all of the cell lines derived from cervical cancers. The hybridization patterns of HPV DNA after endonuclease digestion differed among cell lines, suggesting that all of these cell lines were independent isolates. Accordingly, high-risk types of HPV DNA seem to be ubiquitous in cervical cancer. HPV DNA was not detected in the cell lines derived from head and neck cancers or from any other malignancies besides cervical cancer in this study.

Previously, we demonstrated that hepatocyte spheroids exhibited various differentiated structures as observed in the liver tissue. It was also shown that hepatocyte growth was highly suppressed and several differentiated functions, including albumin production and gluconeogenesis, were well preserved in spheroids. To investigate the differentiated functions of cultured hepatocytes in relation to cell morphology, we compared the expression of the albumin and transferrin genes in spheroids with those in monolayers by Northern blot analysis. Production of these proteins in the culture medium was simultaneously examined by ELISA. Gene expression and protein production of both albumin and transferrin were better preserved in spheroids. We also examined changes in the expression of liver-specific genes in response to IL-6. Reduced mRNA levels of both albumin and transferrin was only found in spheroids and no change was observed in monolayers. These results suggest that the regulation of tissue-specific gene expression is better preserved in spheroids, in which hepatocytes are in close contact with each other. en-copyright= kn-copyright= en-aut-name=TamuraTomoyuki en-aut-sei=Tamura en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoideNorio en-aut-sei=Koide en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HadaHajime en-aut-sei=Hada en-aut-mei=Hajime kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsujiTakao en-aut-sei=Tsuji en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=Okayama University affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University affil-num=4 en-affil= kn-affil=Okayama University affil-num=5 en-affil= kn-affil=Okayama University en-keyword=hepatocyte kn-keyword=hepatocyte en-keyword=spheroid kn-keyword=spheroid en-keyword=primary culture kn-keyword=primary culture en-keyword=gene expression kn-keyword=gene expression en-keyword=IL-6 kn-keyword=IL-6 END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=3 article-no= start-page=153 end-page=159 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=199506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Increased urinary excretion of non-albumin antigen detected with YO-2, a novel monoclonal antibody, in diabetic patients. en-subtitle= kn-subtitle= en-abstract= kn-abstract=Monoclonal antibodies were raised against urine proteins from diabetic patients. An antibody, YO-2, stained three protein bands with apparent molecular weights of 66, 49, and 36 kDa. These bands were not reactive with an anti-human albumin antibody. The urine levels of YO-2-reactive antigen in the normal control were 0.97 +/- 0.37 U/g-Cr (units per gram of urine creatinine) (mean +/- SD). Those of the normo-, micro-, and macroalbuminuric diabetic patients, respectively, were 1.38 +/- 1.36, 2.87 +/- 2.07, and 3.92 +/- 3.33 U/g-Cr. They were significantly higher in the micro- and macroalbuminuric patients. The urine levels of YO-2-reactive antigen had no significant correlation with the urine albumin levels and hemoglobin A1c. We concluded that; a) monoclonal antibody YO-2 recognized a non-albumin urine antigen increasingly excreted in diabetic patients with nephropathy, b) recent glycemic control of diabetes would not significantly affect the urinary excretion rate of YO-2-reactive antigen, and c) the excretion rate and probably the mechanism of YO-2-reactive protein differed from those of albumin. The urine levels of YO-2-reactive antigen could be a clinical marker of diabetic nephropathy.
