The role of GSH in the metabolism of halothane, however, is still unclear. We therefore pretreated male rats with phorone to deplete hepatic GSH, phenobarbital as a microsomal enzyme inducer and exposed them to halothane 1 % for 4 h under hypoxia (10% O<jats:sub>2<\/jats:sub>). Increases in serum enzyme activities of alanine aminotransferase (GPT) and sorbitol dehydrogenase (SDH) were observed 24 and 48 h later. Histomorphological examinations showed centrilobular hepatic necrosis. In GSH\u2010depleted rats the increments of serum enzyme activities and histomrphological alterations were significantly aggravated as compared with controls.<\/jats:p><jats:p>In this model (+)\u2010catechin protected against halothane\u2010induced hepatotoxicity as evidenced by reduced serum enzyme elevations and morphological alterations whereas diethyldithiocarbamate faiied to exert any protective effects. Free fluoride concentrations in plasma was used as an index of the non\u2010oxidative defluorination of halothane. Increased plasma fluoride levels were observed under conditions which evoked hepatotoxicity but did not correlate with the protective effect of (+)\u2010catechin. Our experimental data indicate that glutathione might be involved in the non\u2010oxidative metabolic pathways of halothane. Furthermore, (+)\u2010catechin seems capable of protecting against the direct toxic effect of halothane metabolites resulting from the reductive pathways.<\/jats:p>","DOI":"10.1002\/jat.2550070206","type":"journal-article","created":{"date-parts":[[2006,10,16]],"date-time":"2006-10-16T00:51:42Z","timestamp":1160959902000},"page":"105-110","source":"Crossref","is-referenced-by-count":9,"title":["Halothane hepatotoxicity in glutathione depleted rats"],"prefix":"10.1002","volume":"7","author":[{"given":"Klaus\u2010Peter","family":"Wilhelm","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maged","family":"Younes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dieter","family":"Sellin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claus\u2010Peter","family":"Siegers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,1,11]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1177\/0310057X7900700102","article-title":"Hepatotoxicity and halothane metabolism in an animal model with application for human toxicity","volume":"7","author":"Cousins M.
