Hepatocyte growth factor/scatter factor (HGF/SF) is a multifunctional growth factor that promotes proliferation, motility, and morphogenesis in epithelial cells. Recently the HGF receptor, c-met protooncogene product, has been shown to be expressed in developing limb buds (Sonnenberg, E., D. Meyer, M. Weidner, and C. Birchmeiyer, 1993. J. Cell Biol. 123:(More)
Metallothionein (MT), a low molecular weight metal-binding protein, has been related to zinc and copper metabolism, the acute-phase response, and cellular proliferation. In this study, we investigated changes in zinc metabolism and MT gene expression occurring in tissue damage and repair during wound healing in mouse skin. Northern blot analysis revealed(More)
Although data loss has become an important problem that needs to be solved in many types of organizations, possible routes of data loss have become complicated and numerous, making countermeasures difficult to develop. Fujitsu Laboratories is developing data loss prevention technologies that integrate know-how related to mobile devices, data searching(More)
A 33-year-old man presented with Kimura's disease of the hard palate. Serological examination showed no elevation in the number of eosinophils or in IgE level, but histological examination revealed well-developed lymph follicles with increased numbers of eosinophils. In addition, immunohistochemical examination revealed that the IgE concentrations were(More)
Serum specimens drawn at random from Hokkaido inhabitants were tested for antibody to the hepatitis A virus (anti-HAV) by radioimmunoassay. The prevalence in different age groups was as follows, cord blood and newborn infants 44.4%, under one year 0%, 1-9 years 5.3%, 10-19 years 0%, 20-29 years 9.1%, 30-39 years 80%, 40-49 years 90%, and over 50 years 100%.(More)
The outbreak of hepatitis A occurred in an institution for the mentally retarded children in Bibai city. Hepatitis A virus infection was observed in 50 of 144 children who were sensitive to HAV (infection rate 34.7%). Clinical findings and severe liver dysfunction were seen in 30 of 50 cases and the rate of apparent infection was 60.0%. The route of(More)

Somatic cell hybrids which produced antibodies against HBsAg were established by fusing the splenocytes of BALB/c mice immunized with purified HBsAg and the myeloma cell line P3X63Ag8 using polyethylene glycol 1,000. Mouse ascites were obtained by inoculating 13 hybridoma clones, and 8 of them produced high PHA titer antibodies of 10(2) to 10(6) against(More)
