(Randomized controlled trial)]. / Vliyanie vnutrennego kursovogo priema modifitsirovannykh selenom mineral'nykh vod na mineral'nuyu plotnost' kostnoi tkani posle dlitel'nogo diet-indutsirovannogo narusheniya metabolizma v eksperimente.

INTRODUCTION: The phenomenon of therapeutic and prophylactic effect of natural mineral waters (MW) used to restore tissue tolerance to glucose and normalize basal insulin secretion in metabolic syndrome is well known. At the same time, the use of selenium-enriched MW is promising due to its multitarget action including participation in the regulation of the protein-synthesizing function of cells. AIM: To study the effect of internal course intake of selenium-modified mineral waters of different composition on bone mineral density after long-term diet-induced metabolic disorders in the experiment. MATERIAL AND METHODS: The study was carried out on outbred male white rats that were distributed into 3 control groups (CG) and 4 main groups (MG). In CG1 14 animals received laboratory food and drinking water; in CG2 14 animals were modeled for diet-induced metabolic disorders, and they were withdrawn from the experiment the day after the cancellation of the hypercaloric diet (180 days); after the cancellation of the hypercaloric diet 180 days later 14 animals with diet-induced metabolic disorders in CG3 had a standard diet (laboratory food and drinking water) for 30 days. In the experimental groups (EG), the animals similarly to CG3 were modeled diet-induced metabolic disorders, after the cancellation of the diet they had a standard diet and watering with MW. In MG1 18 animals were given MW1 (Essentuki-4); in MG2 19 animals had a course of MW1Se (Essentuki-4 enriched with selenium); in MG3 14 animals had a course of MW2 (Slavyanovskaya); in MG4 18 animals had a course of MB2Se (Slavyanovskaya enriched with selenium). The weight (body weight) of the animals was monitored monthly. Biochemical studies, densitometry and computed microtomography were used to determine the effectiveness of MW. RESULTS: The characteristics of spongy bone tissue of femoral metaphysis of the rats of the control groups revealed disorders of varying degrees, but, despite this, the bone tissue structure of the examined vertebral bodies in animals without a hyper caloric diet (CG1) was preserved. The analysis of the study results demonstrated a significant effectiveness of selenium-enriched MW in regulating metabolic processes (p<0.05-p<0.01), bone mineral density (p<0.05), reduced bone resorption (p<0.05), that is, the characteristics of spongy bone tissue of femoral metaphysis and vertebral bodies of animals showed a clear tendency to restore bone structure. CONCLUSION: The results of this study make it possible to predict an increase in the effectiveness of medical rehabilitation of patients with somatic diseases when selenium-enriched MW is included in the programmes.

[Investigation of the metabolic effects of selenium-modified Essentuki mineral water in the experiment]. / Izuchenie metabolicheskikh éffektov modifitsirovannoi selenom mineral'noi vody Essentukskogo tipa v éksperimente.

BACKGROUND: The urgent tasks of experimental balneology are to design and investigate of the action of native mineral waters (MW) enriched with essential trace elements in order to improve their therapeutic and prophylactic effects. OBJECTIVE: To investigate the mechanisms of direct action of the cycle intake of Essentuki MWs modified with selenium (Essentuki Novaya - MW1, Essentuki No. 4 - MW2) on healthy animals. MATERIAL AND METHODS: According to the experimental conditions, 102 male albino rats were divided into 7 groups using a simple randomization method. Group 1 (n=15) received only drinking water (DW) (a control group); Group 2 (n=13) used native MW1; Group 3 (n=13) took native MW2; Group 4 (n=15) had MW1 with selenium (MW1Se1 - 3 mcg/kg); Group 5 (n=15) received MW1Se2; Group 6 (n=15) had MW2Se1 - 300 mcg/kg; and Group 7 (n=16) used MW2Se2. RESULTS: After cycle drinking, the body weight of the animals in the experimental groups did not significantly differ from that in the control group and was determined within the normal species range. X-ray densitometry showed that the body fat composition in the rats was lower than the control values only after MW1Se1, MW1Se2, and MW2Se1 cycles. The rat lipid spectrum in different groups displayed differences: the atherogenic index was low after MW1, MW1Se1, and MW1Se2 cycles. The blood glucose levels increased in the rats after drinking native MWs (F=2.7; p=0.01). After selenium-modified MW cycles, the blood glucose levels corresponded to the control values. The blood of experimental and control animals showed no differences in bone mineral density (BMD), levels of hormones (insulin, thyroxine, dehydroepiandrosterone (DHEA) and end products of protein metabolism. Selenium-modified Essentuki No. 4 changed the orientation of functional relationships from negative to positive ones between glucose and BMD. CONCLUSION: The findings suggest that cycle drinking with native and selenium-enriched Essentuki MWs differently affect the animals. The Essentuki Novaya MW (MW1, MW1Se1, and MW1Se2) drinking cycles predominantly affected in reducing blood atherogenic lipids. The volume of an animal fat component was lower after selenium-modified Essentuki Novaya and Essentuki No. 4 water (MW1Se1, MW1Se2, and MW2Se1) cycles. A direct relationship between DHEA and BMD was found in animals after using the selenium-enriched Essentuki No. 4 cycle.

[The evaluation of the effectiveness of the application of bischofite-modified yellow clay (an experimental studi)]. / Otsenka éffektivnosti primeneniia zheltoi gliny, modifitsirovannoi bishofitom (éksperimental'noe issledovanie).

BACKGROUND: The topical problems in balneotherapeutics and health resort activities in general are the development of the yellow clay-based preparations enriched in the natural mineral bischofite and the investigation of their therapeutic effects with the purpose of improvement of their curative potential. AIM: The objective of the present study was to evaluate the effectiveness of the course of the experimental therapeutic applications of the yellow clay obtained by the open pit mining of its deposits located in the vicinity of Pyatigorsk and modified by the addition of bischofite. MATERIAL AND METHODS: The experiments were carried out with the use of 57 eugamic Wistar male rats with adjuvant arthritis. The yellow clay supplemented with bischofite in various concentrations was applied in 12 procedures each 15 minutes in duration every other or every two days beginning from the 38th day of experimentally-induced arthritis. The animals were allocated to five groups as follows: group 1 included the healthy animals that served as controls (n=5), groups 2-5 were comprised of the animals with adjuvant arthritis. The animals included in group 2 served as the experimental model of adjuvant arthritis (n=8), those comprising group 3 were treated by the applications of yellow clay without additives (n=14), group 4 was composed of the animals with adjuvant arthritis treated by the applications of yellow clay containing 10% of bischofite (n=15), the animals in group 5 having adjuvant arthritis were treated by the applications of yellow clay containing 20% of bischofite (n=15). RESULTS: The study has demonstrated the reduction of the reactively enhanced relative abundance of, activated T-cells, and B-lymphocytes down to the respective control values in the animals with adjuvant arthritis after the course of applications of the yellow clay preparations. Simultaneously, normalization of the immunoregulatory index, IRI, (the T-helpers to cytotoxic T-lymphocytes ratio) was documented. The treatment was associated with the strong dependence of the interleukin (IL-1ß) contents on the cortisol level and the well apparent relationship between the levels of interleukins and IRI. Specifically, the relation between IL-1ß and IRI following the application of non-modified yellow clay was characterized as (r=+0.8, p=0.03) in comparison with the relation between IL 6 and IRI (r=+0.8, p=0.03) after the treatment with yellow clay containing 10% of bischofite or between IL 6 and IRI (r=+0.8, p=0.004) after the application of yellow clay containing 20% of bischofite. CONCLUSION: The results of the study give evidence of the immunomodulatory action of yellow clay modified by the addition of bischofite. They suggest the promising opportunities for the application of these preparations for the management and rehabilitation of the patients presenting with the diseases of the musculoskeletal system in the future.
