Theresa C. Peterson, C. Noel Williams – 1 March 1987 – Aryl hydrocarbon hydroxylase activity was detectable in cultured macrophage monolayers of peripheral blood monocyte origin. Peripheral blood monocytes were isolated from patients with biopsy‐confirmed liver disease and healthy volunteers. Macrophage monolayers were prepared and incubated at 37°C. After 24 hr, the aryl hydrocarbon hydroxylase activity and cellular protein concentration were assayed on cell homogenates.

Anil Gautam, Oi‐Cheng Ng, James L. Boyer – 1 March 1987 – Studies of canalicular bile secretion have been limited due to lack of direct access to the canalicular lumen. Isolated rat hepatocyte couplets, consisting of two hepatocytes enclosing a canalicular space, have been proposed as a primary secretory unit that may be useful for direct studies of unmodified canalicular bile secretion. The present study examines their structural characteristics and plasma membrane reorganization.

Wolfgang E. Fleig, Eduard F. Stange, Roland Hunecke, Wolfgang Schönborn, Ulrike Hurler, Kordula Rainer, Wilhelm Gaus, Hans Ditschuneit – 1 March 1987 – To compare the efficacy of endoscopic paravariceal sclerotherapy and oral propranolol in the prevention of recurrent upper gastrointestinal bleeding, 78 cirrhotic patients were randomly assigned to either treatment after an endoscopically proven bleed from esophageal varices.

Brigitte Dragosics, Peter Ferenci, Eva Hitchman, Helmut Denk – 1 March 1987 – Two hundred forty‐two voluntary blood donors, referred after detection of HBsAg positivity, underwent clinical evaluation and liver biopsy and were prospectively followed for an average of 3.5 years. At initial testing, 65% of HBsAg carriers had normal laboratory findings; during follow‐up, 26% of these carriers developed abnormal test results, at least transiently. Liver histology was normal in 31.4%, revealed nonaggressive liver disease in 63.6% and chronic active hepatitis or cirrhosis in 5%, only.

Andrew K. Burroughs – 1 March 1987 – The density and affinity of beta‐2‐adrenoceptors on mononuclear cells from peripheral blood were studied in fifteen patients with cirrhosis of different severity and in thirteen controls. There was no significant difference between cirrhotic patients and controls in density or affinity of beta‐2 binding sites. Within the cirrhotic group, however, the number of binding sites per cell was significantly lower in patients with severe ascites than in patients with mild to moderate or no ascites.

Wolfgang Base, Carl Barsigian, Alisa Schaeffer, Ellen Shaw, Jose Martinez, Willis C. Maddrey – 1 March 1987 – We investigated the effects of the branched‐chain amino acids—valine, leucine and isoleucine—or their keto analogs, the branched‐chain keto acids—α‐ketoisovaleric acid, α‐ketoisocaproic acid and α‐keto‐β‐methylvaleric acid—on protein synthesis and secretion by monolayers of rabbit hepatocytes incubated with [35S] methionine in pulse‐chase and steady‐state experiments.
