John C. Hoefs – 1 August 1992 – The albumin difference or gradient between serum ascites is presumed to be an effective estimate of the colloid osmotic pressure gradient, although this has never been directly demonstrated. The colloid osmotic pressure gradient is controlled by the degree of portal hypertension. Thus the albumin gradient is clinically useful in detecting patients with ascites caused by portal hypertension, although some overlap in such patients' albumin gradients exists compared with those of patients without portal hypertension.

Norifumi Kawada, Natsuo Ueda, Yasuhiro Mizoguchi, Kenzo Kobayashi, Takeyuki Monna, Seiji Morisawa, Kazunori Ishimura, Toshiko Suzuki, Shozo Yamamoto – 1 August 1992 – Rats were treated with heat‐killed Propionibacterium acnes and subsequent injection of a small amount of lipopolysaccharide after 7 days. After 24 hr most of the rats died of massive liver cell necrosis. Nonparenchymal liver cells were isolated from this liver injury model and incubated with arachidonic acid.

Yoshiyuki Nakatsuji, Akihiro Matsumoto, Eiji Tanaka, Hiroyuki Ogata, Kendo Kiyosawa – 1 August 1992 – Serum samples from 100 patients with non‐A, non‐B hepatitis–related chronic liver disease and 100 patients with hepatitis B–related chronic liver disease were tested by first‐generation and second‐generation enzyme‐linked immunosorbent assays, a second‐generation recombinant immunoblot assay and the nested polymerase chain reaction.

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.

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.

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).

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.

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.
