[Blood cobalamins and xenobiotic-metabolizing enzymes in rat liver in adjuvant arthritis].
Changes in the total cobalamin content and spectrum of individual forms of these vitamins in blood cells and plasma as well as the activities of enzymatic systems of xenobiotic metabolism in liver microsomes of rats with experimental adjuvant arthritis (AA) have been studied. The total cobalamin content in the blood plasma of rats with AA was increased in comparison with intact animals; however, leucocytes from AA rats were deficient in methylcobalamin (MeCbl). A correlation was found between the ratios of individual cobalamin forms and their total content which was differently expressed in experimental and control animals. The development of AA was associated with marked inhibition of the cytochrome P-450-dependent monooxygenase system of the liver and glutathione transferase. The possibility of correction of these disturbances by MeCbl is discussed.
