1 Weaning rats were fed ad libitum isocaloric diets containing 5% and 20% casein based proteins. 5% protein diet was protein deficient diet. Pair fed rats with the 5% protein group were maintained simulta neously on 20% protein diet but the amount restricted to the amount taken up by PEM group. 2 Glutathione, antioxidative enzymes, lipid peroxida tion and histopathological studies in liver and only glutathione and antioxidative enzymes in blood were carried out. 3 Rats fed the 5% protein diet developed a severe protein energy malnutrition (PEM) whereas those on pair-fed diet developed mild to moderate PEM. 4 Glutathione related thiols, superoxide dismutase, glutathione peroxidase, catalase and glutathione-S- transferase with (1 Chloro 2,4-dinitro benzene (CDNB) substrate) were decreased in liver with concomitant increase of lipid peroxidation in severe PEM. In blood glutathione, glutathione peroxidase and catalase were decreased while superoxide dismutase was increased in severe PEM group. 5 Mild to moderate PEM (pair-fed group) also resulted in similar changes in liver except glutathione peroxidase, lipid peroxidation in liver and superoxide dismutase in blood. 6 Hepatic injury was detectable only in the severe PEM group. 7 Oxidative-stress and hepatic injury occurred in severe PEM and to a lesser degree in mild to moderate PEM.
