Abstract
The effect of Gomisi (dried ripe fruit of schizandra chinensis) on chlorodifluoroethylene (CDE) and chlorotrifluoroethane (CTE) formation was investigated. The incubation mixtures for the measurement of reductive metabolites of halothane consisted of liver microsomal suspensions, 3 mM NADPH, extract solution of Gomisi and halothane in 0.1 M potassium phosphate buffer (pH 7.4). The production of CDE and CTE was inhibited by Gomisi in a doseβdependent way. The production were reduced to half in the presence of 0.5% Gomisi extract in the reaction mixture. The results suggest that Gomisi can inhibit the reductive metabolism of halothane in vitro; thus it may protect against halothaneβinduced hepatitis.
