John Colman – 1 March 1989

Wan Chen, Jean‐Louis Gendrault, Anne‐Marie Steffan, Eric Jeandidier, André Kirn – 1 March 1989 – Fat‐storing cells were isolated from 15‐day‐old mouse sinusoidal cell cultures (Kupffer or endothelial cells), where they had multiplied abundantly; they were then purified by a negative selection method based on the fact that they do not possess Fc receptors, as do both other types of cells.

Fujio Katsumoto, Kohji Miyazaki, Fumio Nakayama – 1 March 1989 – The role of Kupffer cells during reparative regeneration of rat liver was investigated with an in vitro experimental model. Conditioned media from primary cultures of Kupffer cells isolated from intact and regenerating liver were added to primary cultures of hepatocytes, and [3H]thymidine incorporation into DNA was studied. Kupffer cell‐conditioned media from intact liver and regenerating remnant liver significantly stimulated DNA synthesis in hepatocytes as compared with control media (p<0.05).

Paul Calès, Max Pierre‐Nicolas, Antonio Guell, Jean‐Louis Mauroux, Anne Franco‐Sempe, Jean‐Pierre Vinel, Gilles Geraud, Jean‐Pierre Pascal – 1 March 1989 – Since it has been suggested that propranolol could lead to hepatic encephalopathy, we undertook a study to assess the effects of propranolol on cerebral blood flow and cerebral functions. Sixteen patients with alcoholic cirrhosis and large esophageal varices and without major hepatic dysfunction (Child‐Pugh score <14) or previous hepatic encephalopathy were randomized to receive either propranolol or placebo.

Chia‐Ming Chu, Yun‐Fan Liaw, Chia C. Pao, Miau‐Ju Huang – 1 March 1989 – To study the etiology of acute hepatitis superimposed upon previously unrecognized asymptomatic HBsAg carriers, paired sera were collected in acute and convalescence phases for measurement of HBeAg, anti‐HBe, hepatitis B virus DNA and anti‐delta from 76 adult patients with acute hepatitis who were HBsAg positive but IgM anti‐HBc negative or positive only at low titer. None of them were IgM anti‐hepatitis A virus positive on admission.

Thomas D. Boyer – 1 March 1989

Ryan J. Huxtable – 1 March 1989 – Hepatic veno‐occlusive disease is the most frequent cause of hepatic vein obstruction in children. Only the small and medium veins are involved. The initial vascular lesion is endothelial edema, followed by phlebosclerosis and occlusion of the small vessels, leading to secondary necrosis of liver cells, progressive fibrosis, and ultimately cirrhosis. The disease was first recognized in Jamaica in 1954, and subsequently reported from other parts of the world.

Morris Sherman, Tim J. Harrison – 1 March 1989

Antoon F. M. Moorman, Jacqueline L. M. Vermeulen, Robert Charles, Wouter H. Lamers – 1 March 1989 – Immunohistochemical analysis of human liver (8 to 94 years) shows a compartmentation of ammonia‐metabolizing enzymes across the acinus. The highest concentration of carbamoylphosphate synthetase (ammonia) is found in the parenchymal cells around the terminal portal venules. Glutamine synthetase is found in a small pericentral compartment two to three cells thick.

Massimo Colombo, Roberto de Franchis, Maurizio Tommasini, Angelo Sangiovanni, Nicola Dioguardi – 1 March 1989 – To assess the efficacy of β‐blockers in preventing rebleeding in selected cirrhotic patients and to compare the tolerance, safety and patient compliance of a selective and a nonselective β‐blocker, 94 patients were randomly assigned to propranolol (32 patients), atenolol (32 patients) or placebo (30 patients). Randomization was made at least 15 days after the bleeding episode.
