Investigation of the antioxidant activity and cardioprotective effect of reamberin and cytoflavin in newborn rats exposed to chronic hemic hypoxia

Abstract: The authors analyzed the antioxidant activity of reamberin and cytoflavin and evaluated their cardioprotective effect, by investigating lipid peroxidation and oxidative modification of plasma proteins, as well as the ultrastructure of newborn rat cardiomyocytes under chronic hemic hypoxia induced by sodium nitrite. Reamberin and cytoflavin can reduce the manifestations of mitochondrial dysfunction and the degree of cardiomyocyte damage in the neonatal rats due to the antioxidant and membrane-protective propert… Show more

“…Though we cannot state that it can completely prevent the hypoxic impairment. But still polyphenols are able bind free radicals [4,6] and make it possible to reduce the amount of free radicals, to obtain a greater amount of ATP even in conditions of insufficient substrates and to prevent the progression of oxidative stress in the early stages of ischemic and hypoxic damage to the myocardium, which was confirmed in this study.…”

“…An important role in the treatment and prevention of adverse effects of the activation of free radical processes in histotoxic hypoxia is given to the antioxidant therapy -the promising direction of which is the use of various natural and synthetic antioxidants [4][5][6]. Despite the widespread use of antioxidants applied to protect the body from the damaging effects of lipid peroxidation stress, their scientifically proven effect on the antioxidant-prooxidant status of the organism exposed to histotoxic stress has not been adequately studied.…”

“…Гетерогенные разобщенные митохондрии имели лизированные кристы, но чаще всего эти органеллы были разрушены полностью. В части митохондрий выявлено полное разрушение крист, а их а б [10]. Выявление подобных морфологических признаков указывает на необратимый характер повреждений сократительных КМЦ, а также на повреждение их сарколеммы и мембран митохондрий [2].…”

“…Таким образом, полученные морфологические данные с учетом имеющихся в литературе сведений, свидетельствующих о снижении синтеза АТФ клетками и активацией процессов перекисного окисления липидов в условиях гипоксии, указывают, что под влиянием нитритов, и прежде всего, самого нитритного аниона и его метаболитов, происходит изменение свойств клеточных мембран, обусловленное нарушением липидного состава мембран [10,15]. Разрушение липидного бислоя как клеточных, так и внутриклеточных мембран приводит к патологическому увеличению их проницаемости, и как следствие повышенной деструкции митохондриальных мембран в условиях дефицита кислорода.…”
