[Effect of carbostimulin and vitamin D3 on activity of glycolytic enzymes of rabbit bones, regenerates and muscles].

Activity of glycolysis enzymes such as: phosphofructokinase, aldolase, phosphoglucomutase, was determined in the regenerate of a bone, bone fragments, native bone and, for the sake of comparison, in the animal muscles after the radius resection and feeding of carbostimulin and its mixture with vitamin D3 for 10 days. On the 12th day after the radius resection the phosphofructokinase activity in rabbits increases in the native and operated bones as compared to that in bones of nonoperative animals. In the group of rabbits which were fed on the mixture of carbostimulin and vitamin D3 the phosphofructokinase activity is 7-2 times as high.

[Effect of carboxylation reactions stimulation on intensity of 14CO2 fixation in rabbits with posthemorrhage anemia and on repairing of blood components in human anemia].

The repair processes with posthemorrhage anemia were studied in experiment and clinics as affected by the preparation (sodium bicarbonate and magnesium, manganese and zinc sulphates in a ratio of 25:5:0.1:0.1) which stimulates the carboxylation reactions in the organism.

[Stabilizing effect of calcium ions on glucose oxidase of Penicillium vitale].

Reconstruction of P. vitale glucose oxidase from apeonzyme and coenzyme (FAD) was studied as affected by iodine acetate as well as mercury and calcium ions. Mercury ions, iodine acetate as well as the labilizing fraction (flavin adenine-containing component) are established to inhibit the reconstruction affecting the sulphydryl groups of the apoenzyme which take part in addition of FAD to it.

[Dissociation of Penicillium vitale catalase under the effect of urea and acid pH].

Conditions are studied for Penicillium vitale catalase dissociation into subunits under the effect of urea (0.7-8.5 M) and acid pH (5.

[Incorporation in vivo of 14C-precursors into pyrimidine nucleotides of chicken liver and spleen tissues].

Maximum incorporation of the label after administration of 14C-bicarbonate to free pyrimidine nucleotides begins by the 60th minute. Radioactivity of cytidine nucleotides at all time points is four-eight times as low as that of uridine nucleotides. 2-14C-orotic acid is incorporated into acid-soluble nucleotides and RNA of the liver and spleen tissues.
