Henny G. Peltenburg, Wim T. Hermens, George M. Willems, J. Guus Flendrig, Ellen Schmidt – 1 November 1989 – Pathological elevations of the plasma activities of liver enzymes are not simply related to the quantitative release of such enzymes from the liver. Several enzymatic indices, such as the well‐known de Ritis quotient, may be determined by differences in the time course of hepatic enzyme release, rather than reflecting true differences in the released quantities of various enzymes.

Rita Aldini, Aldo Roda, Patrizia Simoni, Pierluigi Lenzi, Enrico Roda – 1 November 1989 – The hepatic extraction of unconjugated and taurineconjugated bile acids, provided with different hydrophilicity values, has been measured in the perfused rat liver, in order to evaluate the role of the bile acid structure and bile acid hydrophilicity on their uptake by the liver. Ursocholic, cholic, ursodeoxycholic and chenodeoxycholic acids, free and taurine‐conjugated, were injected into the portal vein in dose response studies, using a nonrecirculating perfusion system.

Tadashi Terada, Yasuni Nakanuma – 1 November 1989 – Recently, macroregenerative nodules in cirrhotic livers have been suspected to be among the putative precancerous lesions in human hepatocarcinogenesis. We examined the morphologies of 99 macroregenerative nodules in 44 cirrhotic livers with special emphasis on stainable iron. In 26 macroregenerative nodules (26%), stainable iron selectively accumulated within the macroregenerative nodules themselves, and little or no iron was found in the surrounding regenerative nodules.

M. Gary Brook, Peter Karayiannis, Howard C. Thomas – 1 November 1989 – Twenty‐one pretreatment variables were assessed for their significance in response prediction using data from 114 patients given α‐interferon for chronic hepatitis B virus infection.

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.

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.
