Abstract

Acute ethanol treatment of rats (5 g/kg) has a biphasic effect on the glutathione content of the erythrocyte. After 3 h of intoxication there is a diminution in total GSH equivalents, followed by a recovery to basal values 6 h after treatment. The decrease of total GSH equivalents is mainly due to a diminution of the oxidized form of the tripeptide. Concomitantly a marked increase in the plasma level of glutathione was found at 3 h, followed by a diminution to values obtained at time zero.

摘要

用乙醇(5克/千克)对大鼠进行急性处理,会对红细胞中的谷胱甘肽含量产生双相效应。中毒3小时后,总谷胱甘肽当量减少,随后在处理6小时后恢复至基础值。总谷胱甘肽当量的减少主要是由于三肽氧化形式的减少。与此同时,在3小时时发现血浆中谷胱甘肽水平显著升高,随后降至处理前(零时)的水平。
