Study of the dynamics of catalase activity in heart and muscle of rats by mechanical action on the barrier gematologichesky

The hematoophthalmic barrier is one of the mechanisms of resistance that serves to protect the body and prevents homeostasis disorder when the body is affected by factors that can disturb this balance. One of the complications of mechanical trauma of the eye and violation of the hematoophthalmic barrier is the appearance of oxidative stress on the background of the general inflammatory process in violation of cellular structures. Objective: to study the dynamics of catalase activity in the heart and muscle tissue of rats under oxidative stress caused by mechanical action on the hematoophthalmic barrier. Materials and methods. The study was carried out on white neonatal mature healthy male rats of six months of age, weighing 200–220 g and having 150 pieces. The activity of catalase in heart and muscle tissue was studied before the beginning of the experiment, as well as on the 1st, 3rd, 5th, 7th and 14th day of the experiment using the standard Korolyuk M.A. method. The dynamics of catalase activity was evaluated by different methods of treatment of mechanical eye trauma, including the use of quercetin antioxidant. The results of the study. It was found that in addition to the standard therapy of mechanical eye injury injection of quercetin, the activity of catalase in the heart and muscular tissue after falling on the background of induced oxidative stress increases to the values of physiological norm by 14 days, which indicates the effective elimination of oxidative stress. Conclusions. The activity of catalase in rat heart and muscle tissue under oxidative stress caused by mechanical influence on hematoophthalmic barrier is most effectively stabilized under standard therapy of mechanical eye injury with addition of quercetin in the form of injections.
