CLINICAL AND FUNCTIONAL STATE OF THE THYROID GLAND IN WOMEN OF PERI- AND POSTMENOPAUSAL AGE WITH METABOLIC SYNDROME.

The article deals with the problem of the clinical and functional relationship between the state of the thyroid gland in women of menopausal age and the components of the metabolic syndrome (MS). The purpose of the study: to assess the relationship between thyroid dysfunction and various components of MS in women of peri- and postmenopausal age. 80 menopausal women (mean age 55 years) were examined, of which 40 people with MS constituted the main group, and the comparison group - a similar number of women without MS. The inclusion criterion in the study was the presence of signs of abdominal obesity (AO) according to the WHO criteria (2008). Anthropometric, functional (BP), laboratory (lipidogram, TSH, freeT4, antibodies to TPO, FSH, LH, urinary iodine concentration) and instrumental (ultrasound of the thyroid gland) data, statistical analysis using the program SPSSStatistics version 20 were evaluated. The women were divided into two age groups: group 1 - perimenopausal and group 2 - postmenopausal. There were 40 people in each group (20 women with MS and 20 women without MS). It has been shown that peri- and postmenopausal women with MS have subclinical hypothyroidism. The influence of peripheral blood TSH levels in peri- and postmenopausal women with MS on body weight, carbohydrate and lipid metabolism, and sex hormones was established.

Correction of Alcohol-Induced Damage to Mitochondria in Cardiac and Cerebral Cells by Derivatives of Neuroactive Amino Acids.

We studied LPO intensity and respiration of mitochondria in brain and heart cells of rats receiving 5% ethanol for 20 weeks and treated with derivatives of neuroactive amino acids. Chronic semicompulsory alcohol intoxication increased the concentration of LPO products in cardiac and cerebral mitochondria by 46 and 45% (diene conjugates), by 97 and 8% (diketones), and by 28 and 81% (malondialdehyde), respectively, reduced activity of antioxidant enzymes in cardiac and cerebral mitochondria by 24 and 45% (glutathione peroxidase) and by 22 and 26% (superoxide dismutase), respectively, and uncoupled the process of respiration and ATP synthesis, which manifested in a decrease in respiratory control (V3/V4 ratio according to Chance). Glutamic acid derivative Neuroglutam (26 mg/kg) and GABA derivative succicard (44 mg/kg) administered intraperitoneally daily for 28 days after termination of alcoholization decreased the levels of primary and secondary LPO products, up-regulated activity of antioxidant enzymes in mitochondria of the heart and brain, and moderated the mitochondrial dysfunction.

[Age-specific changes in the functional indices of rats' cardiac mitochondria in chronic alcohol intoxication.]

The effect of chromic continuous consumption of 5 and 10% ethyl alcohol over 6 months on the respiratory function and oxidant/antioxidant status of rats' cardiac mitochondria of different gender and age has been studied. A decrease in oxygen consumption rate by cardiomyocyte mitochondria in the metabolic conditions V2, V3, V4 according to Chance involving activation of respiratory chain complexes I, I+II and II in elderly (24-month old) animals as compared to young (11-month old) animals. As the rats were ageing, the concentration of lipid peroxidation (LPO) products (malondialdehyde) was increasing, while the activity of antioxidant enzymes (superoxide dismutase and glutathione peroxidase) was decreasing in cardiomyocyte mitochondria. Chronic alcoholization of 24-month old rats of both genders resulted in a more pronounced decline in the respiratory function activity of cardiac mitochondria, uncoupling of respiration and oxidative phosporylation, reduced activity of antiradical protection enzymes and increased LPO products as compared to younger rats.
