Liver tumor promoters stimulate growth of transplanted hepatocellular carcinomas

Per O. Seglen, Gunnar Sæter, Per E. Schwarze – 1 August 1990 – Cell suspensions or tissue fragments from primary hepatocellular carcinomas and benign neoplastic nodules, induced by treating rats with chemical carcinogens, were transplanted by intraportal injection or subcapsular implantation in the livers of syngeneic host rats. Both nodule and carcinoma transplants produced high numbers of hepatocellular carcinomas in the hosts 2 to 5 mo after transplantation.

Predictive value of whole blood chemiluminescence in patients with alcoholic hepatitis

Françoise Lunel, Beatrice Descamps‐Latscha, Diane Descamps, Yves Le Charpentier, Patrick Grippon, Dominique Valla, Jean‐François Cadranel, Johannes Trum, Pierre Opolon – 1 August 1990 – Recent reports suggest that ethanol metabolism leads to reactive oxygen intermediates that may be responsible for the lesions observed in alcoholic hepatitis. This study investigated the production of reactive oxygen intermediates in peripheral blood phagocytes of patients with alcoholic hepatitis and attempts to evaluate its predictive value.

Renal and systemic hemodynamics in experimental cirrhosis in rats: Relation to hepatic function

Georg Wensing, Ramzi Sabra, Robert A. Branch – 1 July 1990 – The onset of sodium retention in the phenobarbital and carbon tetrachloride model of cirrhosis in the rat is preceded by a linear decrease in hepatic function as measured by the aminopyrine breath test. Sodium retention occurs when liver function decreases below a critical threshold. Changes in systemic hemodynamics may be responsible for initiating the development of renal sodium retention.

Prevention of hepatocyte injury and lipid peroxidation by iron chelators and α‐tocopherol in isolated iron‐loaded rat hepatocytes

Bipin K. Sharma, Bruce R. Bacon, Robert S. Britton, Chanho H. Park, Christopher J. Magiera, Rosemary O'Neill, Nicholas Dalton, Patricia Smanik, Theodore Speroff – 1 July 1990 – These experiments were performed to characterize the relationship between lipid peroxidation and hepatocyte viability in iron overload. Hepatocytes were isolated from rats with chronic dietary iron overload and the effects of in vitro iron chelation on lipid peroxidation, cell viability and ultrastructure were studied over a 4‐hr incubation period.
