Влияние глицина на интенсивность перекисного окисления липидов и активность антиоксидантной системы в динамике экспериментального инфаркта миокарда

Abstract

Изучена эффективность глицина в ограничении интенсификации процесса перекисного окисления липидов в динамике экспериментального инфаркта миокарда у кроликов. При введении глицина в дозе 100 мг/кг массы тела наблюдается повышение содержания малонового диальдегида через 3 часа коронароокклюзии, напротив 1 часа у контрольных животных. Через 3, 6, 12, 24 и 72 часа коронароокклюзии содержание продуктов перекисного окисления липидов – малонового диальдегида и диеновых конъюгатов – в плазме крови кроликов, получавших глицин, оказалось ниже по сравнению с контрольными значениями. Более низкое содержание продуктов перекисного окисления липидов у кроликов с инфарктом миокарда при лечении глицином сопровождалось более высокими значениями активности ферментов антиокислительной системы – супероксиддисмутазы и каталазы. Предполагается, что антиоксидантное действие глицина опосредуется его антистрессорными свойствами.

The efficacy of glycine in limiting the intensification of the process of lipid peroxidation in the dynamics of experimental myocardial infarction in rabbits. When administered glycine 100 mg/kg body weight observed increase in the content of malondialdehyde koronarookklyuzii at 3:00, 1:00 opposite the control animals. At 3, 6, 12, 24 and 72 hours koronarookklyuzii content of lipid peroxidation products – malonic dialdehyde and conjugated diene in the blood plasma of rabbits treated with glycine was lower compared to control values. A lower concentration of lipid peroxidation products in rabbits with myocardial infarction in the treatment of glycine was accompanied by higher activity of antioxidant enzymes systems – superoxide dismutase and catalase. It is assumed that the antioxidant effect of glycine is mediated by its antistress properties.
