[Characterization of plant phenolic compounds by cyclic voltammetry].

Phenolic acids and flavonoids were characterized by cyclic voltammetry and total antioxidant activity in the reaction with the ABTS cation radical. Anode peak voltages (Eap) and their pH dependences were determined for the studied phenolic acids and flavonoids. The Eap and Trolox equivalent antioxidant capacity (TEAC) values were found to correlate for polyphenols, which react with the ABTS cation radical in two steps.

[Comparison of the efficiency of polygalacturonase and beta-glucosidase enzyme preparations in stabilization of cherry plum wine material].

Pektofoetidin and Pectinex, enzyme preparations with the highest polygalacturonase and beta-glucosidase activities, were covalently immobilized on DEAE cellulose and Aminosilochromes 10 and 30. After treatment of cherry plum wine material with the soluble and immobilized enzyme preparations, the content of phenolics increased by 26 and 40%, respectively. The increase was accompanied by a decrease in the protein content (by up to 37%), carbohydrate content (by 17% on the average), and antioxidant activity (5-37%).

[Tuberculosis in servicemen of the reserve called up for the military training].

There were disclosed 3 cases of respiratory tuberculosis in called up servicemen of the reserve from Siberian military district. The two of them being heavy clinical forms of tuberculosis with the disintegration of pulmonary tissue and bacterioexcretion were found out due to complaints. Both patients were socially unfavourable, have not been examined with fluorography for many years, and did not complain being called up.
