The levels of some important drug activating and detoxyfying enzymes were estimated in the livers of Swiss mice treated with a local brand of country liquor. Following liquor ingestion in male mice elevated levels of hepatic cytochrome P-450 were observed, while female mice did not show this. Cytochrome b5 levels remained unchanged. Similarly in male mice, increase in hepatic reduced glutathione levels were obtained while in female mice, decrease in this was observed. The activity of glutathione S-transferase was not changed. It is suggested that the increases in cytochrome P-450 and in hepatic reduced glutathione may be important determinants in carcinogenecity of the country liquors.
在给瑞士小鼠喂食某一本地品牌土制酒之后,对其肝脏中一些重要的药物激活酶和解毒酶水平进行了评估。雄性小鼠摄入酒后,观察到肝脏细胞色素P - 450水平升高,而雌性小鼠未出现这种情况。细胞色素b5水平保持不变。同样,雄性小鼠肝脏中还原型谷胱甘肽水平升高,而雌性小鼠中则观察到该水平下降。谷胱甘肽S - 转移酶的活性未发生变化。有人提出,细胞色素P - 450和肝脏还原型谷胱甘肽的增加可能是土制酒致癌性的重要决定因素。
