Tomoteru Kamimura, Antonio Ponzetto, Ferruccio Bonino, Stephen M. Feinstone, John L. Gerin, Robert H. Purcell – 1 January 1983 – Electron microscopic observations were carried out on five HBsAg carrier chimpanzees infected with delta (δ) agent and two chimpanzees infected with human non‐A, non‐B hepatitis. The cytoplasmic tubular structures, which have been recognized in the liver of chimpanzees infected with human non‐A, non‐B hepatitis, were found also in the liver of HBsAg carrier chimpanzees infected with 5 agent.

Jean‐Pierre Villeneuve, Hélène Fortunet‐Fouin, Dominique Arsène – 1 January 1983 – Following cimetidine administration, 60% of the dose is excreted as unchanged drug in the urine, and 40% is eliminated by metabolism. We evaluated the effect of liver disease on cimetidine disposition by comparing its kinetics in 7 healthy subjects and 8 patients with alcoholic cirrhosis.

Aiges, Garth Alperstein, Mervin Silverberg – 1 January 1983 – Differentiating intrahepatic cholestasis from extrahepatic biliary tract obstruction may be difficult. Four patients with intraoperative cholangiographic evidence of extrahepatic ductal atresia who underwent hepatoportoenterostomy are described. All were ultimately shown to have arteriohepatic dysplasia with hypoplastic but patent extrahepatic ductal systems.

Flavio O. Nervi, Reginald Del Pozo, Carmen F. Covarrubias, Beatriz O. Ronco – 1 January 1983 – We tested the hypothesis that progesterone, an inhibitor of cholesterol esterification in liver microsomes, increases biliary cholesterol output by increasing the availability of cholesterol. Initial bile samples of 20 min were obtained from acute bile fistula rats after seven daily doses of progesterone (5 to 55 mg per kg of body weight). Biliary cholesterol output correlated with the doses of progesterone, r = 0.64 (p < 0.005).
