[The physiological analysis of cross adaptation to regular cold exposure and physical activities].

Research is devoted to the comparative analysis of results of cold adaptation and physical training. The adaptive shifts occurring in an organism under the influence of a hardening (douche by a cold shower 2 times a day 2 minutes long within 6 weeks) and running training on the treadmill (30 minutes at 70-80% of individual VO2max, 3 times a week, within 6 weeks) were compared at 6 the same subjects. The interval between the two cycles of training was no less than 3 months.

[Effect of training on treadmill performance, aerobic capacity and body reactions to acute cold exposure].

An attempt was made to test the hypothesis that regular physical activity at the anaerobic threshold is able to stimulate an increase in the amount of body fat brown or beige, which can manifest itself in increasing lactate utilization during exercise and increase the reactivity in response to acute regional cooling. The methods used are: ramp test, regional acute cold exposure, measurement of gas exchange, lactate and glucose in the blood, heart rate, and heart rate variability, blood pressure and respiration variability at rest and during standard functional tests; infrared thermal imaging, statistical methods of results analysis. Workout 10 physically active volunteers (7 males and 3 females) on a treadmill at a speed corresponding to 75-80% of the persona VO2max for 30 minutes 3 times per week at a fixed ambient temperature 21-22°C for 6 weeks resulted in a significant (from 19 to 39%) increase in test work duration but VO2max on average changed little.

[Characteristics of the clinical course and treatment of epitympanitis with cholesteatoma in children].

A specific form of chronic epitympanitis has been identified in children. This pathology includes tympanic membrane perforation above he lateral process of the malleus and is termed cholesteatomic epitympanitis . This is because it is accompanied by epidermis growth across the perforation into Prussak's space.

[Endoscopic polypectomy in the surgical treatment of diffuse polyposis of the large intestine].

The article analyses experience in the treatment of 81 patients with diffuse polyposis who underwent subtotal resection of the colon with abdominoanal resection of the rectum and downward displacement of the right parts into the anal canal. It is shown that growth of the remaining occasional polyps and appearance of new polyps are encountered in the maintained parts of the colon and upper parts of the gastrointestinal tract in the postoperative period. The authors found that endoscopic polypectomy allows the right colon to be preserved in 92.
