Tateo Kawase, Shinzo Kato, Charles S. Lieber – 1 November 1989 – The effects of chronic ethanol feeding on hepatic lipid peroxidation, ascorbic acid, glutathione and vitamin E levels were investigated in rats fed low or adequate amounts of dietary vitamin E. Hepatic lipid peroxidation was significantly increased after chronic ethanol feeding in rats receiving a low‐vitamin E diet, indicating that dietary vitamin E is an important determinant of hepatic lipid peroxidation induced by chronic ethanol feeding.

Kentaro Yoshioka, Shinichi Kakumu, Motohiro Arao, Yasuhiko Tsutsumi, Masaki Inoue – 1 November 1989 – We investigated the production of tumor necrosis factor α by peripheral blood mononuclear cells of patients with chronic liver disease and its association with hepatitis activity. Tumor necrosis factor α production was measured with an enzyme‐linked immunosorbent assay.

Mark J. Czaja, Francis R. Weiner, Shizuko Takahashi, Marie‐Adele Giambrone, Peter H. Der Van Meide, Huub Schellekens, Luis Biempica, Mark A. Zern – 1 November 1989 – Since interferons have been shown to affect the synthesis of matrix proteins such as collagen in several in vitro systems, the potential role of γ‐interferon in inhibiting hepatic fibrosis was investigated. Hepatic cells, consisting primarily of hepatocytes, were treated with recombinant γ‐interferon for 24 hr.

Francisco Guarner, John L. Wallace, Wallace K. Macnaughton, Geoffrey C. Ibbotson, Vicente Arroyo, Joan Rodés – 1 November 1989 – Systemic endotoxemia has been observed in patients with acute and chronic liver failure, and bacterial endotoxin is known to increase vascular permeability. We investigated in the normal rat the effects of intraportal endotoxin administration and the possible mediation of these effects by platelet‐activating factor.

Zhuhui Cai, Zhiqing Shi, Morris Sherman, Anthony M. Sun – 1 November 1989 – To determine the in vitro function of microencapsulated hepatocytes, viable hepatocytes were isolated from rats and encapsulated within biocompatible alginatepolylysine membranes for in vitro studies. Urea formation, prothrombin and cholinesterase activity, the incorporation of tritiated leucine into intracellular proteins and the immunolocation of synthesized albumin were monitored in culture.

Mary J. Ruwart, Karen F. Wilkinson, Bob D. Rush, Thomas J. Vidmar, Kenneth M. Peters, Keith S. Henley, Henry D. Appelman, Kiyoung Y. Kim, Detlef Schuppan, Eckert G. Hahn – 1 November 1989 – To determine whether a serum parameter of collagen metabolism, serum procollagen type III peptide, correlated with hepatic collagen in a model of diet‐induced fibrosis, rats were fed a control or cirrhogenic diet for 6 months and treated with either subcutaneous vehicle or the hepatoprotective prostaglandin 16,16‐dimethyl prostaglandin E2 (100 μg per kg) twice daily.

James P. Nolan – 1 November 1989

Mogens Vyberg – 1 November 1989 – Liver needle biopsies from patients with non‐A, non‐B chronic active hepatitis and so‐called abnormal bile duct epithelium were studied with a three‐dimensional method. Photographs of bile duct structures in serial sections were transferred to acrylic plates. Five bile duct lesions of a not previously described diverticular type were revealed. The diverticuli were of varying shape with a diameter of 30 to 110 μ and a length of 75 to 150μm budding from small (12 to 25μm), slightly ectatic bile ducts. The diverticular epithelium was disordered.
