Hepatitis B virus, hepatitis non‐A, non‐B virus and hepatitis delta virus in lyophilized antihemophilic factor: Relative sensitivity to heat

Robert H. Purcell, John L. Gerin, Hans Popper, William T. London, John Cicmanec, Jorg W. Eichberg, Jack Newman, Michael E. Hrinda – 1 November 1985 – Lyophilized plasma derivatives are more stable to heat than when they are in the liquid state. Commercial Factor VIII (antihemophilic factor) was seeded with a measured quantity of hepatitis B virus. The contaminated material was then lyophilized and subjected to heat of 60°c for 30 hr. Chimpanzees were inoculated with the heat‐treated antihemophilic factor or sham‐treated antihemophilic factor that had been held at 4°c.

Ultrastructural immunocytochemical demonstration of HLA class I antigens in human pathological liver tissue

Rita De Vos, Chris De Wolf‐Peeters, Joost J. Den Van Oord, Valeer Desmet – 1 November 1985 – Major histocompatibility complex products Class I (HLA Class I) antigens are not expressed on the surface of normal human hepatocytes but become so in pathological conditions. The purpose of this study was to specify the ultrastructural topography of HLA Class I antigens expression.

Screening methods for early detection of hepatocellular carcinoma

Kenichi Kobayashi, Tatsuho Sugimoto, Hiroshi Makino, Mikio Kumagai, Masashi Unoura, Nobuyoshi Tanaka, Yasuhiro Kato, Nobu Hattori – 1 November 1985 – The value of various screening methods in the detection of early hepatocellular carcinoma was investigated in 95 patients with cirrhosis. Infusion hepatic angiography and computed tomography with angiography were performed yearly, ultrasound every 3 months, and determination of serum α‐fetoprotein levels every 2 months. “Space‐occupying lesions” suspicious for hepatocellular carcinoma were found in 13 of the 95 cases (13.7%).

Effects of hypoxia and phenobarbital treatment on the metabolism of mitomycin C in experimental animals

Fumio Nomura, Kunihiko Ohnishi, Hirofumi Koen, Shinji Iida, Yuichi Tanabe, Hitoshi Hatano, Kunio Okuda – 1 November 1985 – To evaluate the effects of anaerobic conditions and inducers for the mixed‐function oxidase system on the metabolism of mitomycin C, a bioreductive alkylating agent widely used for the treatment of hepatocellular carcinoma, experiments so designed were performed in rats and mice.

Biochemical indicators of vitamin A depletion in children with cholestasis

Olivier Amédée‐Manesme, Harold C. Furr, Fernando Alvarez, Michelle Hadchouel, Daniel Alagille, James Allen Olson – 1 November 1985 – Biochemical indicators of vitamin A status were measured in 24 children (1 month to 6 years old) with severe cholestasis starting early in life and in 21 children (3 months to 13 years old) with liver disease but without cholestasis. Liver vitamin A concentrations, expressed as micrograms of retinol per gram of liver (mean ± S.D.), were 6.3 ± 7.1 (range: 0.14 to 28) and 143 ± 108 (range: 18 to 424), respectively, in cholestatic and noncholestatic children.

Establishment of a cell line from a woodchuck hepatocellular carcinoma

Masashi Unoura, Kenichi Kobayashi, Kenichi Fukuoka, Fumiaki Matsushita, Hideo Morimoto, Tohru Oshima, Shuichi Kaneko, Nobu Hattori, Seishi Murakami, Hiroshi Yoshikawa – 1 November 1985 – A new cell line derived from a woodchuck hepatocellular carcinoma serially transplanted in athymic nude mice has been established and named WH257GE10. The original tumor in the nude mouse system produces woodchuck hepatitis surface antigen and albumin. In addition, woodchuck hepatitis virus DNA is integrated into cellular DNA.

Hepatitis B vaccine: Low postvaccination immunity in hospital personnel given gluteal injections

Karen L. Lindsay, David A. Herbert, Gary L. Gitnick – 1 November 1985 – Although other investigators have found excellent response rates to the hepatitis B vaccine, we report here an unusually low rate of seroconversion following hepatitis B vaccination in a group of apparently healthy medical center personnel. Only 67% of these individuals developed adequate postvaccination antibodies to HBsAg, in contrast to 85 to 96% in other studies.
