[The effect of reamberin on the antioxidant status in children with epilepsy]. / Primenenie reamberina dlia korrektsii antioksidantnogo statusa pri épilepsii u detei.

AIM: To study the efficacy of reamberin in treatment of epilepsy in children and to evaluate its effect on the antioxidant status. MATERIAL AND METHODS: The antioxidant activity of reamberin was investigated in children with epilepsy: 16 patients received intravenous reamberin once daily for 5 days in addition to carbamazepine. Patients of the control group (n=15) received only carbamazepine. The efficacy of the drug was evaluated by the levels of lipid hydroperoxides, conjugated dienes, and malondialdehyde and by the activity of the main components of the antioxidant system (ceruloplasmin, vitamin E, catalase) in the blood of patients. RESULTS AND CONCLUSION: Reamberin significantly reduces the plasma levels of lipid hydroperoxides by 16%, conjugated dienes by 12%, and malondialdehyde by 25% compared with the patients of the control group. An analysis of the effect of succinate-containing drugs on the activity of the antioxidant system components has shown that blood concentrations of ceruloplasmin, vitamin E and catalase are by 35, 14% and 15%, respectively, higher than those in the control group. Thus, the addition of reamberin into the treatment of children with epilepsy should be considered pathogenetically justified, clinically reasonable, and promising.

[EFFECT OF CITOFLAVIN ON THE PARAMETERS OF LIPID PEROXIDATION IN BLOOD PLASMA OF RATS UNDER COLD STRESS CONDITIONS.]

The possibility of correcting free radical oxidation of lipid membranes by the administration of cytoflavin was experimentally studied in rats. It is established that daily cold exposure for 3 h leads to increase in the level of lipid hydroperoxides, diene conjugates, and malonic dialdehyde on the background of decrease in activity of the antioxidant system in the blood of experimental animals. The introduction of cytoflavin (100 mg/kg, i.p.) for 21 day immediately prior to cold exposure leads to reliable (p < 0.05) decrease in the blood level of lipid hydroperoxides (by 13 - 21%), diene conjugates (by 24 - 25%), and malonic dialdehyde (by 20 - 33%) in comparison to rats of the control group. Analysis of the effect of cytoflavin on activity of the antioxidant system components showed that the level of ceruloplasmin and vitamin E in the blood of animals was reliably (p < 0.05) higher by 10 - 33% than analogous indicator in rats of the control group. Thus, the application of cytoflavin under conditions of long-term influence of cold on the organism of animals leads to stabilization of the processes of lipid peroxidation on the background of increased activity of the blood antioxidant system.
