title: Effects of buthionine sulfoximine and cysteine on the hepatotoxicity of butylated hydroxytoluene in rats.
abstract: Pretreatment with buthionine sulfoximine (BSO; 900 mg/kg) induced the elevation of serum GOT and GPT activities in a non-toxic dose of butylated hydroxytoluene (BHT; 250-500 mg/kg) in rats. The elevation of serum enzyme activities was accompanied by a remarked depletion of the hepatic glutathione (GSH) concentration. In contrast, pretreatment with cysteine (100-200 mg/kg) inhibited the elevation of serum enzyme activities at a toxic dose of BHT (1000 mg/kg). The effects of BSO and cysteine on BHT-induced hepatotoxicity in rats are discussed.
