[Relationship between values of antioxidant enzyme system activity in various tissues of intact rats].

It was studied the relation between activities of ferments an antioxidant system: of superoxide dismutase, catalase and GSH-peroxidase in the homogenates of livers, lungs and cerebrum of intact rats. When activities were brought to identical units of measurement, it was determined that relation of activities can see with a point to view of chemical kinetics laws for consecutively-parallel reactions. It is followed from the result that the activity of catalase livers can be explained by the participation of catalases in other reactions, which were connected with forming a hydrogen peroxide.

[Biochemical mechanisms of the toxic effect of oxalates].

The effect of oxalic acid and its salts on the biochemical systems of the homeostasis of white rats were investigated. It has been shown that oxalates inhibit enzymes of energy metabolism and cause the changes in parameters of nephrotoxicity, electrolyte balance of blood plasma and urine, lipid peroxidation, antiperoxidational defence system.
