The changes in the biochemical indices of blood in cobalt intoxication on the background of the regulators of the expression of endothelial NO-synthase

Abstract

On the background of chronic cobalt intoxication in rats develops oxidative stress. This is accompanied by a decrease in the content of total metabolites of nitric oxide in the blood serum. The reasons for lower levels of the vasodilatation factor are the following: a deficiency of L-arginine and the increase in the content of the inhibitor of NOS-3. We found a decrease in the bioavailability of nitric oxide due to the increase in the content of oxidized low density lipids, total cholesterol and cholesterol-lowering lipids high density.
