Hepatic metabolism during acute ethanol administration: A phosphorus‐31 nuclear magnetic resonance study on the perfused rat liver under normoxic or hypoxic conditions

Franck Desmoulin, Paul Canioni, Christian Crotte, André Gérolami, Patrick J. Cozzone – 1 March 1987 – The effect of ethanol metabolism on the energetic parameters and intracellular pH of the isolated perfused rat liver from fed rats was studied by phosphorus‐31 nuclear magnetic resonance spectroscopy. This technique allowed us to analyze nondestructively and in real time the role of low oxygen tension on the possible injurious effect of ethanol on the liver cells.

Characterization of desmin‐positive rat liver sinusoidal cells

Mikihiro Tsutsumi, Akira Takada, Shujiro Takase – 1 March 1987 – Hepatic sinusoidal lining cells were isolated from mature male rats (12 months old) and cultured in order to clarify the characteristics of the Ito cells (fat‐storing cells). Desmin staining was used as a marker in the isolation of the Ito cells, and a highly purified desmin‐positive cell fraction was obtained. Less than 10% of the desmin‐positive cells were positive for vitamin A auto‐fluorescence.

Bile acid transport: Lessons from the intestine

Richard H. Moseley – 1 March 1987 – The transport of bile acid was studied in basolateral membrane vesicles isolated from rat small intestine. Taurocholate transport into an osmotically reactive intravesicular space was Na+ independent. The uptake of taurocholate in jejunal and ileal vesicles preloaded with sulfate was stimulated with respect to uptake in unpreloaded vesicles. Glycocholate inhibited the transstimulation of taurocholate uptake by sulfate.

Liver levels of vitamin a and cellular retinol‐binding protein for patients wth biliary atresia

David E. Ong, Olivier Amédée‐Manesme – 1 March 1987 – We have examined whether the amount of cellular retinol‐binding protein in human liver is related to the amount of vitamin A stored in the liver. Levels of vitamin A, as retinol and retinol esters, and of cellular retinol‐binding protein have been determined in liver samples from 6 normal adults and 11 children with biliary atresia, with and without vitamin A treatment. The level of cellular retinol‐binding protein in the liver was not related to the liver vitamin A concentration examined over a 300‐fold range of vitamin A levels.

Hereditary defect of hepatobiliary cysteinyl leukotriene elimination in mutant rats with defective hepatic anion excretion

Michael Huber, Albrecht Guhlmann, Peter L. M. Jansen, Dietrich Keppler – 1 March 1987 – Hepatobiliary and renal elimination of cysteinyl leu‐kotrienes were investigated in a mutant rat strain with a hereditary defect in the hepatobiliary excretion of conjugated bilirubin, dibromosulfophthalein and oua‐bain. After intravenous injection of [3H]leukotriene C4, the initial half‐life of radioactivity circulating in blood was 79 ± 15 sec (S.D.) in transport mutant rats as compared to 31 ± 6 sec (S.D.) in normal Wistar rats.

Diuresis in Portuguese

Harold O. Conn – 1 March 1987 – Standardization of a therapeutic approach for ascites due to chronic liver disease was prospectively tried in 100 patients. The four progressive steps were: I—relative bed rest associated to with‐drawal of toxic agents, and restriction of salt (40 mEq) and water (1.000ml per day) for 5 to 7 days. In twenty two patients a good diuretic response was observed. Step II, initiated only for patients who did not respond to step I, corresponded to the introduction of espironolactone, 150 mg/day, for at least 6 days.
