抄録 The definite diagnosis of persimmon phytobezoar (i.e., diospyrobezoar) is often accomplished by a component analysis using infrared spectroscopy. However, no studies have been conducted to investigate which substance is the best as a standard for the component analysis. Here we analyzed tannic acid, Japanese persimmon (kaki), fermented persimmon extract (kaki-shibu), conventional dried persimmon, and dried persimmon smoked in sulfur (ampo-kaki) by infrared spectroscopy to determine which would be optimal as a component analysis standard. The spectrum between 1,600 to 600cm-1 of a persimmon phytobezoar was quite similar to the spectrum of kaki-shibu rather than that of tannic acid. Consequently, we conclude that kaki-shibu should be used as a standard for infrared spectroscopy analyses of persimmon phytobezoars.

抄録 Adult rat hepatocytes assemble to form multicellular spheroids under non-adherent environments such as immobilized chondroitin sulfate-proteoglycan in primary culture. 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.

抄録 <p>Serum des-gamma-carboxy prothrombin (DCP) is commonly used to detect hepatocellular carcinoma (HCC). This review focuses on the clinical features of DCP-positive HCC and the molecular function of DCP in HCC. DCP-positive HCC demonstrates more aggressive clinicopathological features than DCP-negative HCC. Analysis of the biological effects of DCP revealed that DCP acts as a growth factor in both an autocrine and paracrine manner. DCP stimulates HCC cell proliferation through the Met-Janus kinase 1-signal transducer and activator of transcription 3 signaling pathway, whereas for vascular endothelial cells, it stimulates cell proliferation and migration through the kinase insert domain receptor-phospholipase C-gamma-mitogen-activated protein kinase signaling pathway.</p>

抄録 The prevalence of hepatitis C virus (HCV) genotypes in Myanmar in comparison with the rest of Southeast Asia is not well known. Serum samples were obtained from 201 HCV antibody-positive volunteer blood donors in and around the Myanmar city of Yangon. Of these, the antibody titers of 101 samples were checked by serial dilution using HCV antibody PA test II and Terasaki microplate as a low-cost method. To compare antibody titers by this method and RNA identification, we also checked HCV-RNA using the Amplicor 2.0 test. Most high-titer groups were positive for HCV-RNA. Of the 201 samples, 110 were successfully polymerase chain reaction (PCR) amplified. Among them, 35 (31.8%) were of genotype 1, 52 (47.3%) were of genotype 3, and 23 (20.9%) were of type 6 variants, and phylogenetic analysis of these type 6 variants revealed that 3 new type 6 subgroups exist in Myanmar. We named the subgroups M6-1, M6-2, and M6-3. M6-1 and M6-2 were relatively close to types 8 and 9, respectively. M6-3, though only found in one sample, was a brand-new subgroup. These subtypes were not seen in Vietnam, where type 6 group variants are widely spread. These findings may be useful for analyzing how and when these subgroups were formed.

抄録 Nursing support might help patients with chronic hepatitis C (CHC) remain in good mental and physical condition during interferon (IFN) therapy. However, the effects of nursing support have not been studied adequately in this context. This case-control study evaluated the effects of nursing support during IFN therapy. Twenty-four CHC patients who received pegylated IFN and ribavirin were enrolled. Nurses advised patients on the maintenance of their mental and physical condition at weekly visits, based on the results of written questionnaires. An additional 24 patients who received IFN therapy without nursing support and who were matched for age, sex, platelet count, viral serogroup and IFN regimen were selected with propensity score matching as controls. The patients with nursing support during IFN therapy achieved higher sustained virological responses (79%) than those without nursing support (58%). Adherence to the IFN and ribavirin regimens at 24 weeks of therapy were slightly higher in the patients with nursing support than those without it, but these differences were not statistically significant. Adherence to ribavirin after 24 weeks of therapy was significantly higher in those with nursing support than those without it (93% and 66%, p=0.045). These results suggested that nursing support services could contribute to the virological responses of CHC patients by promoting drug-regimen adherence.
