Coinfection study of precore mutant and wild‐type hepatitis B‐like virus in ducklings

Wan‐Long Chuang, Masao Omata, Toshiki Ehata, Osamu Yokosuka, Kazuhiko Hosoda, Fumio Imazeki, Masao Ohto – 1 March 1994 – The precore mutant hepatitis B virus often emerges from a mixed infection with combined wild‐type and precore mutant viruses. Nevertheless, the precore mutant does not seem to be an evolutionarily favored strain.

“Inapparent” hepatitis B virus infection and hepatitis C virus replication in alcoholic subjects with and without liver disease

Anna Linda Zignego, Marco Foschi, Giacomo Laffi, Monica Monti, Grazia Careccia, Roberto Giulio Romanelli, Enrichetta de Majo, Roberto Mazzanti, Giampiero Buzzelli, Giorgio la Villa, Paolo Gentilini – 1 March 1994 – We evaluated hepatitis B virus DNA and hepatitis C virus RNA in sera from 110 HBsAg and IgM HBc antibody–negative heavy drinkers (50 cirrhosis, 13 chronic active hepatitis, 25 fatty liver with or without mild to moderate fibrosis, alcoholic hepatitis or both and 22 healthy alcoholic subjects) with polymerase chain reaction.

Pathogenesis of posttransfusion viral hepatitis in children with β‐thalassemia

Mark Feitelson, Laura Lega, Juanhui Guo, Massimo Resti, Maria E. Rossi, Chiara Azzari, Baruch S. Blumberg, Alberto Vierucci – 1 March 1994 – The pathogenesis of posttransfusion hepatitis was determined in 14 children with β‐thalassemia. All had blood samples obtained in 1980 or 1981, were vaccinated against hepatitis B virus in 1983 and had another serum sample collected in 1989. Seven children had detectable antibodies against hepatitis C virus before vaccination, and all were positive in 1989.

Endothelin‐1 is involved in the pathogenesis of ischemia/reperfusion liver injury by hepatic microcirculatory disturbances

Moritaka Goto, Yoshiyuki Takei, Sunao Kawano, Kouichi Nagano, Shingo Tsuji, Eiji Masuda, Yoshiya Nishimura, Shigetoshi Okumura, Toru Kashiwagi, Hideyuki Fusamoto, Takenobu Kamada – 1 March 1994 – Hepatic microcirculatory perturbation is observed after ischemia/reperfusion. Endothelin‐1, a potent vasoconstrictive peptide, is known to modulate local circulation. This study was designed to examine whether endothelin‐1 participates in the mechanism of microcirculatory disturbance and damage of the liver after ischemia/reperfusion.

Biliary phospholipases in the prairie dog model for cholesterol cholelithiasis

Michael L. Booker, Wayne W. Lamorte – 1 March 1994 – Lysolecithin has been implicated as a contributing factor in the pathogenesis of cholecystitis and cholesterol cholelithiasis. The phospholipases are key enzymes in the generation of a number of metabolites including lysolecithin, but conflicting reports exist concerning the presence of these enzymes in the biliary tract.

Liver transplantation for Wilson's disease: Indications and outcome

Michael L. Schilsky, I. Herbert Scheinberg, Irmin Sternlieb – 1 March 1994 – The objective of this study was to determine the indications for and results of liver transplantation in patients with Wilson's disease on the basis of results of a survey with retrospective review of data obtained on 55 transplants performed at centers in the United States and Europe. The study group comprised 32 females and 23 males, aged 8.5 to 51 yr, with features diagnostic of Wilson's disease.

Endothelial activation and circulating vascular adhesion molecules in alcoholic liver disease

David H. Adams, Patrizia Burra, Stefan G. Hubscher, Elwyn Elias, Walter Newman – 1 March 1994 – Alcoholic hepatitis is characterized by hepatocyte necrosis associated with infiltration of the liver parenchyma by neutrophils. The mechanisms responsible for recruiting neutrophils to the liver are unknown. We report high circulating levels and tissue expression of the endothelial adhesion molecule E‐selectin in alcoholic hepatitis.

Characterization of a chicken hepatoma cell line with a specific defect in fibrinogen secretion

Carole Oddoux, Gerd Grieninger – 1 March 1994 – This study characterizes plasma protein synthesis and its hormonal regulation in a chicken hepatoma cell line, with particular emphasis on fibrinogen. Whereas virtually all aspects of hemopexin, transferrin and albumin production in these cells corresponded to those of cultured primary hepatocytes, fibrinogen was not secreted. Analysis of fibrinogen subunit synthesis revealed a specific defect in synthesis of one subunit, γ, correlating with a lack of its mRNA.

Decreased expression of liver glutathione peroxidase in Long‐Evans cinnamon mutant rats predisposed to hepatitis and hepatoma

Hiroshi Suemizu, Shinichi Yoshimura, Noritoshi Takeichi, Tetsuya Moriuchi – 1 March 1994 – The Long‐Evans Cinnamon rat is a mutant strain that contracts hereditary hepatitis and, eventually, spontaneous hepatoma. Recently, abnormal copper accumulations in Long‐Evans Cinnamon rat livers were shown to be genetically linked to the development of hepatitis.
