[Complex analysis of risk factors of hypertension in subjects involved in managerial activity].

We performed complex analysis of genetic and nongenetic factors facilitating development of arterial hypertension in subjects involved in managerial activity and revealed peculiarities of dermatoglyphic phenotype of susceptibility to this type of pathology. By means of methods of pattern recognition we assessed power and character of effect of each of investigated risk factors. Using mathematical model we elaborated prognosis of efficacy of various preventive procedures.

[The evaluation of the action of microbial enzyme preparations on the motility of the rat and canine small intestine].

The effect of combined microbial enzyme agents trizyme and triaze containing alkaline and neutral proteases, lipase, and amilase on the evacuation capacity of the small intestine of conscious rats and of the dog small intestine operated on by the Thiry-Vella method. Therapeutic doses of the enzymatic agents had no noticeable effect on the evacuation function of the intestine. The contraction of bands of the rat intestine induced by electrical stimulation depended on the concentration of the perfusate of the solution of the enzymatic agents.

[The therapeutic efficacy of the triase preparation in experimental pancreatic exocrine insufficiency].

The therapeutical efficiency of the new enzyme preparation Triase which contains microbial lipase, protease, and alpha-amylase was studied in dogs with experimental pancreatic failure. Enzyme maldigestion was made by bandaging the great pancreatic duct with pancreatic trypsin injection. The daily therapeutical dose of Triase (4 tablets) eliminated dyspepsia, creatorrhoea, restored body weight.

[Late results of the surgical treatment of chronic calculous cholecystitis in young patients].

Long-term results of surgical treatment of chronic calculous cholecystitis were investigated in 139 patients of young age. Good results were observed in 83.5% of cases, satisfactory--in 11.

[Isolation and study of the properties of the hemagglutinins produced by Streptomyces badius actinomycetes].

Hemagglutinin inducing polyagglutination of erythrocytes in the presence of the group blood sera was isolated from the supernatant of the culture fluid of Streptomyces badius 0626 by precipitation with ammonium sulfate and subsequent chromatography on Sephadex. Hemagglutinin proved to be a protein containing no lipid or carbohydrate components and possessing no bacterioagglutinating ability. Examination of the culture fluid supernatants of 150 cultures did not reveal any strains definitely exhibiting the transformation capability for human blood groups.
