Brief summary

Previously it was shown that the course of the succinate-containing mixture, which consists of 50% ammonium succinate, small amounts of calcium, magnesium disuccinate, zinc difumarate, sodium L-glutamate, glycine, tocopheryl acetate, facilitates or eliminates pathological symptoms of menopausal syndrome in women during early menopause. This effect was due to the increased sensitivity to the direct and feedback regulatory signals in hypothalamus-pituitary-ovarian axis. In this paper we attempt to experimentally determine the effect of succinate-containing drug on energy metabolism in vivo by analyzing mitochondrial activity in immobilized peripheral blood lymphocytes and on integral indicators of the hormonal status of female rats during reproductive and late post- reproductive periods. Reduction of nitroblue tetrazolium to formazan (cytobiochemiccal study of lymphocyte mitochondria) indicates that the two-week course the chosen substrate composition at a dose of 5.7 mg/kg per day induced activation of succinate dehydrogenase (SDH) and inhibition of α- ketoglutarate dehydrogenase (KDH). Simultaneously it smoothed age differences in the ratio of SDH and KDH activities: in old animals the ratio of SDH/KDH increased from 1.5 to 7 - the value which is inherent to the reproductive female rats. In the presence of malonate (SDH inhibitor) had a high level of free-radical reduction of nitroblue tetrazolium in old rat mitochondria, but formazan level fell to zero after a course of succinate -containing drug. Contrary to expectations, succinate in used composition did not raise blood pressure in animals, but had a pronounced effect on the hormonal status: increased duration of the phases of proestrus and estrus in estrous cycle, along with a sharp shortening of diestrus phase initially elongated in old rats. The observed effects might be assessed as \\\\\\\"anti-aging\\\\\\\" with simpathotonic activation of the neuroendocrine system.


Key words
