title: The diminution of liver glutathione content and changes in activities of antioxidant enzymes in long-term acetaldehyde poisoning.
abstract: The effect of acetaldehyde administration for 4 weeks on antioxidant protection systems was investigated in liver of rats. Liver SOD activity was decreased from control value 542.4 U/g of tissue to 411.2 U/g of tissue in experimental group (24% decrease). GSH-Px activity was practically unchanged and liver CAT activity was significantly decreased (35%). Sulfhydryl compounds in liver non-proteins following ACH treatment were decreased from 4.22 mumol/g of tissue in control group to 2.86 mumol/g of tissue (23%). Furthermore acetaldehyde treatment caused significant increase in MDA level in liver (78% increase).
