There is a widespread belief that when ethanol is fed to rats for a long time, it produces only fatty degeneration without necrosis or fibrosis. In this study, hydrazine sulfate, an inhibitor of low Km ALDH and gluconeogenetic enzymes, was fed with ethanol to rats, and produced more serious pathological changes compared with those found in Lieber's model. Male Sprague-Dawley rats were fed with a low fat liquid diet as a basal diet with ethanol (4%, w/v) and hydrazine sulfate for 4 weeks. At the end of the experiment, plasma aminotransferase levels were found to be elevated. Histological examination showed not only fatty degeneration but also pericellular fibrosis. Therefore, we have evaluated the curative effect of glucogenic amino acids, alanine and glutamine, on this hepatic injury model and found them to be partially protective.

D005234 Fatty Liver Lipid infiltration of the hepatic parenchymal cells resulting in a yellow-colored liver. The abnormal lipid accumulation is usually in the form of TRIGLYCERIDES, either as a single large droplet or multiple small droplets. Fatty liver is caused by an imbalance in the metabolism of FATTY ACIDS.

D005235 Fatty Liver, Alcoholic Lipid infiltration of the hepatic parenchymal cells that is due to ALCOHOL ABUSE. The fatty changes in the alcoholic fatty liver may be reversible, depending on the amounts of TRIGLYCERIDES accumulated. Alcoholic Fatty Liver,Alcoholic Steatohepatitis
D005723 gamma-Glutamyltransferase An enzyme, sometimes called GGT, with a key role in the synthesis and degradation of GLUTATHIONE; (GSH, a tripeptide that protects cells from many toxins). It catalyzes the transfer of the gamma-glutamyl moiety to an acceptor amino acid.
