[State of the hepatobiliary system and intestines in elderly patients with concurrent digestive pathology].

Common aspects have been revealed of structural and functional disorders of the biliary tract and intestine in elderly patients with digestive pathology. We recommend that lipotropic drugs, choleretics, cholekinetics, antioxidants and eubiotics be used in the treatment of the above patients.

[The therapeutic use of a phosphatide food concentrate in diseases of the hepatobiliary system].

Our studies on phosphatide, a food concentrate, produced as a by-product during the extraction of an edible oil in the oil-extraction plants, showed its high efficacy in patients (n = 52) with abnormalities of the hepatobiliary system. The drug having more than 40 weight percent of phosphorus-containing lipids appeared to be efficacious not only in respect of the subjective status of the patients but also the functional state of the liver and paraments characterizing lipid metabolism.

[Properties of glucose isomerase from Streptomyces robeus S-606].

Optimal conditions of the glucose isomerase fixation in a cell are determined by thermal treatment of Str. robeus S-606 biomass. Under these conditions the maximal enzyme activation (by 50-55 percent) is simultaneously observed.
