    Abstract:
    The activity of cellular components of liver detoxification system was studied under the conditions of the absence of vitamin A stores. It is shown that a decrease of p-hydroxylase and N-demethylase activity of cytochrome P-450 simultaneously with a decrease of glutathione-S-transferase activity takes place in the liver microsomal fraction of vitamin A-deficient animals. At the same time the absence of retinoid stores in knock-out animals influences the decrease of only p-hydroxylase activity of cytochrome P-450 system. The increase in glutathione-S-transferase activity is observed in the liver postmicrosomal fraction in mice, kept on vitamin A-deficient diet, while its parametres in knock-out group animals were not statistically different compared to the control.
