摘要:

The effects of retinol and α‐tocopherol‐deficient and supplemented diets on the cytosolic concentration of thiobarbituric acid reactive substances (TBARS) in rat liver have been studied. Physiological lipoperoxidation (LPO) was observed in liver cytosol of control rats (TBARS = 0.315 ± 0.034 nmol of MDA equivalents/mg of liver cytosolic proteins). In retinol‐deficient diets there was a decrease in retinolaemia and the absence of retinol in liver cytosol while cytosolic TBARS increased significantly(P <0.001).
