Clemens Schiessel, Claudia Forsthove, Dietrich Keppler – 1 September 1984 – The hepatic uptake of45calcium (45Ca) was studied in rats after administration of D‐galactosamine (3 mmoles per kg, i.v.). In contrast to measurements of the hepatic calcium content, 45Ca uptake served as a dynamic rather than a static indicator of calcium homeostasis during the transition from reversible to irreversible liver injury which occurs between 3 and 4 hr after injection of the hepatotoxin.

Jean‐Marc Begue, Christiane Guguen‐Guillouzo, Nicole Pasdeloup, Andre Guillouzo – 1 September 1984 – The cytochrome P‐450 content promptly fell in adult rat hepatocytes cultured in conventional conditions whereas no obvious change was detected over a 10‐day period when these cells were co‐cultured with another rat liver epithelial cell type. A concomitant maintenance of the amino‐pyrine N‐demethylase activity and a high aflatoxin B1‐induced cytotoxicity was observed, and addition of phenobarbital to the culture medium produced about a 2‐fold increase in cytochrome P‐450 level.

Alain Frei, Arthur Zimmermann, Kurt Weigand – 1 September 1984 – To evaluate the diagnostic significance of the collagen Type III (Col 1–3) JV‐terminal propeptide of procollagen Type III, with respect to activity and degree of liver fibrosis, Col 1–3 serum concentrations were measured in 111 patients with chronic liver diseases and in 60 patients were correlated with liver histology and morphometry. Col 1–3 was measured by a specific radioimmunoassay. Biopsies were read without knowledge of diagnosis.

Henry W. Kao, Mary Ashcavai, Allan G. Redeker – 1 September 1984 – Hepatitis A IgM antibody (IgM anti‐HAV), detected by commercially available solid‐phase radioimmunoassay, is an accepted marker of acute viral hepatitis A infection. However, persistence of this serological marker far beyond the acute illness and immediate convalescent period has been reported. To determine the persistence of IgM anti‐HAV following clinically manifest acute hepatitis A infection, 59 patients with this diagnosis were followed prospectively until this marker disappeared or persisted for greater than 60 days.

Kurt A. Black, Viravan Virayotha, Thomas R. Tephly – 1 September 1984 – The exhalation of 14CO2 after the administration of [dimethylamino‐14C]aminopyrine to an organism is assumed to reflect the demethylation of aminopyrine by hepatic mixed‐function oxidase activity. The formaldehyde formed as a result of the demethylation of aminopyrine is then sequentially oxidized to formic acid and CO2.

Martin C. Carey – 1 September 1984 – The hydrophilic‐hydrophobic balance of bile salt monomers can be readily quantified by their elution sequence during reverse‐phase high‐performance liquid chromatography. Such studies have demonstrated that subtle variations in bile salt structure have profound effects on the hydrophilic‐hydrophobic balance of this important family of detergent‐like molecules. The common trihydroxy bile salt, cholate, is more hydrophilic than dihydroxy bile salts with alpha‐oriented OH groups.
