[Hydroxylating activity of rat liver microsomes in the period of acute phase protein formation in radiation sickness].
At the height of radiation sickness (7-8 days after irradiation) the accretion of proteins of "acute phase" in rat blood was accompanied by diminution of diminution of hydroxylating activity of microsomes determined by the rate of aminopyrine demethylation. There was an invert correlation between these two indices, and the correlation coefficient was -0.9.

[The effect of ubiquinone Q10 and biotin on the growth and development of premature animals].
Biotin (0.3 mg/kg per os) and ubiquinone Q10 (50 mg/kg, per os) during chronic administration were found to produce stimulating effects on premature animals. The two drugs contributed to a more rapid development of memory and learning processes in premature new-born rats than in mature ones, normalized the major parameters of carbohydrate and lipid metabolism. Some specific features and differences were ascertained in the stimulating effects of biotin and ubiquinone Q10.

[The pharmacological properties of coenzyme A disulfide].
Coenzyme A disulfide (CoA disulfide) was pharmacologically studied. It has been found to normalize lipid and carbohydrate metabolism when given in a dose of 2 mg/kg, i.m., in diverse liver dysfunctions. It possesses an antihypoxic action under hemic and histotoxic hypoxia. When given in small doses (80-160 micrograms/kg, i.v.), CoA disulfide depresses the function of cellular hemostasis.

[The estimation of the level of mutations at the glycophorin A locus in subjects exposed to the chronic action of ionizing radiation].
11 persons, who had been irradiated chronically at low dose rate under occupational conditions in 1950s in doses 220-581 cGy according data of individual film dosimeters, and 5 control persons were examined regarding the level of glycophorin A (GPA) mutation type NO and NN in blood erythrocytes. Significantly higher level of GPA mutations type NO was registered in average in the group of exposed persons (23.2 +/- 4.6 x 10(-6)) compared with the control group (10.2 +/- 2.1 x 10(-6)) through the dose dependence was expressed slightly. The coefficient of the linear regression has equaled (2.3 +/- 1.2 x 10(-6)) Gy. The outlook on GPA assay usage in retrospective biodosimetry is discussed.
