Nodular regenerative hyperplasia in the rat induced by a selenium‐enriched diet: Study of a model

Paulette Bioulac‐Sage, Liliane Dubuisson, Christiane Bedin, Pierre Gonzalez, Eliane de Tinguy‐Moreaud, Henri Garcin, Charles Balabaud – 1 August 1992 – Weaned male rats were fed a 4 ppm selenium diet. Compared after 2 mo with a control group fed a 0.4 ppm diet, the rats' body weights had not significantly decreased and liver function was normal, but portal pressure was 1.8 times higher (p < 0.05). Liver weight was slightly increased (10.3%; p < 0.05). All livers had an abnormal appearance.

Cystic dilatation of peribiliary glands in livers with adult polycystic disease and livers with solitary nonparasitic cysts: An autopsy study

Tetsuji Kida, Yasuni Nakanuma, Tadashi Terada – 1 August 1992 – Cystic dilatation of peribiliary glands of intrahepatic and extrahepatic bile ducts was investigated in autopsied livers with adult polycystic disease (n = 8), in autopsied livers with solitary nonparasitic cysts (n = 18) and in normal autopsied livers (n = 23). In normal livers, cystic dilatation of intrahepatic peribiliary glands was absent or slight, when present. In livers with solitary nonparasitic cysts, cystic dilatation of intrahepatic peribiliary glands was present in varying degrees.

Hormonal status of postmenopausal women with alcohol‐induced cirrhosis: Further findings and a review of the literature

Judith S. Gavaler, David H. van Thiel – 1 August 1992 – The derangements of levels of sex hormones and gonadotropins in alcoholic cirrhotic men are well delineated. The countersituation in alcoholic cirrhotic women has not yet been fully described. This study was performed in postmenopausal women among whom menstrual cycle variations in hormones no longer occur; with such a study population, it is possible to control for confounding factors and thus optimize detection of differences in levels of hormones and hormone interrelationships.

The immune response in chronic hepatitis B virus infection: The “Core” of the problem?

James R. Baker – 1 August 1992 – Individuals with chronic hepatitis B virus (HBV) infection are generally divided into asymptomatic healthy carriers and patients with chronic liver disease. Several studies have suggested that the hepatitis B core antigen could be an immunological target of cytotoxic T lymphocytes (CTL). To investigate the possible pressure site from CTL, the entire core region of HBV DNA was sequenced in 30 subjects (10 asymptomatic healthy carriers and 20 patients with chronic liver disease).

Ischemic injury in liver transplantation: Difference in injury sites between warm and cold ischemia in rats

Tetsuo Ikeda, Katsuhiko Yanaga, Keiji Kishikawa, Saburo Kakizoe, Mitsuo Shimada, Keizo Sugimachi – 1 August 1992 – Using liver allografts with warm or cold ischemia, we evaluated functional and morphological alterations in hepatocytes, sinusoidal endothelial cells and Kupffer cells in a rat transplantation model. All recipients of allografts with either 4 hr of cold or 30 min of warm ischemia lived more than 22 days and were judged viable. On the other hand, all recipients of grafts with 6 hr of cold or 60 min of warm ischemia died within 2 days and were therefore judged to be nonviable.

Purification of 3α‐hydroxysteroid and 3β‐hydroxysteroid dehydrogenases from human liver cytosol

Hajime Takikawa, Makoto Fujiyoshi, Kou Nishikawa, Masami Yamanaka – 1 August 1992 – We previously reported that the human Y′ bile acid binder, which has higher bile acid binding affinities than rat Y′ binders (3α‐hydroxysteroid dehydrogenases), has dihydrodiol dehydrogenase activity and is different from 3α‐hydroxysteroid dehydrogenases. In this study, 3α‐hydroxysteroid dehydrogenases and 3β‐hydroxysteroid dehydrogenase were purified from human liver, and bile acid binding affinities and enzyme kinetics of the 3α‐hydroxysteroid dehydrogenases were studied.
