[The environment and health status of Ukraine's population before and after the Chernobyl AES accident]. / Sostoianie okruzhaiushchei sredy i uroven' zdorov'ia naseleniia Ukrainy do i posle avarii na Chernobyl'skoi AES.

Qualitative and quantitative analyses of the environment and human health during 5 years before and after the Chernobyl accident (1986) provided an original scheme and methods for hygienic assessment of the negative influence of environmental pollution on health. They were tested in the Kiev Region. The accident was found to essentially complicated the environmental and sanitary situation in the region and to negatively affect human health.

[Metabolism in experimental chronic ischemic heart disease]. / Osobennosti metabolizma pri khronicheskoi ischemicheskoi bolezni serdtsa v éksperimente.

An increase in frequency of heart contractions, changes in the bioelectrical heart activity and decrease of the force-pump heart function are observed in the rabbits with model chronic ischemic heart disease lipid metabolism in significantly changed the concentration of cholesterol in the right ventricle myocardium as well as the concentrations of unsaturated lipid acids in the heart tissues increase, while the content of saturated lipid acids and antioxidant activity of plasma decrease. Bioenergetic processes change as follows: succinate-dehydrogenase and alpha-keto-glutarate-dehydrogenase activity decrease, while the concentrations of glycogen, lactic and pyruvic acids and lactate dehydrogenase activity in the heart tissues increase.

[The relation between oxidative processes and the glycogen content in the heart and liver of rabbits with chronic ischemic heart disease]. / Sviaz' mezhdu okislitel'nymi protsessami i soderzhaniem glikogena v serdtse i pecheni krolikov pri khronicheskoi ishemicheskoi bolezni serdtsa.

While laboratory experimental model of coronary heart disease (according to Frol'kis et al.) is developed, activity of succinate dehydrogenase, alpha-ketoglutarate dehydrogenase, Na+, Ka(+)- and Mg2+ ATPase decreases, but activity of lactate dehydrogenase and concentrations of lactic and pyruvic acids in the heart tissue increase. At the same time concentration of glycogene increases more than twice. As far as we can see there is an evidence of a decrease of glycogene utilization due to change in levels of regulatory processes. Despite a decrease of ATP synthesis by the inhibition of tricarboxylic acid cycle the ATP:ADP relation reduces to ATP, as emphatic inhibition of ATPase in the heart tissues takes place in development of the model of the coronary heart disease. The relation between ATP and ADP is considered as a regulator of glycogene utilization. In the liver tissue activity of succinate dehydrogenase, alpha-ketoglutarate dehydrogenase, Na+, K(+)- and Mg2+ ATPase falls, while concentrations of lactic acid grow. No accumulation of glycogen is observed. It is obvious that there are controversial metabolic processes. Experimental data are discussed.

[The toxicity of the "C", "M" and "P" brands of polyvinyl chloride plastisols used for making medical articles]. / O toksichnosti PVKh-plastizolei marok "C", "M", "P", ispol'zuemykh dlia izgotovleniia meditsinskikh izdelii.

It is concluded that polyvinyl plastisols of the mentioned brands should not be used for manufacturing medical products. Only the P brand may be employed for manufacturing balloons for measurement of the blood pressure and for inhalers.

[Toxicological and hygienic evaluation of water obtained by the method of hydration of carbon dioxide]. / Toksikologo-gigienicheskaia otsenka vody, poluchennoi metodom gisdrirovaniia uglekislogo gaza.

The irritating, sensitizing, and toxic effect of water produced by the method of carbon dioxide hydration was examined in animal experiments and human observations. It was found that before and after decontamination this water did not cause skin irritation or organism sensitization, did not have a toxic effect on the CNS, liver, kidneys or blood morphology, and did not deteriorate adaptive capabilities of the animal or human body.

[The effect of ultraviolet irradiation on the cesium-137 and strontium-90 levels in the body of laboratory animals]. / Vliianie ul'trafioletovogo oblucheniia na soderzhanie tseziia-137 i strontsiia-90 v organizme laboratornykh zhivotnykh.

A 10-day course of ultraviolet radiation (intensity: 1/8-2 biodoses daily) did not favour accumulation of cesium-137 in the body but produced some effect on the accumulation of strontium-90. In the real radiation condition in the city of Kiev the daily prophylactic 1/8 biodose may be considered as absolutely safe.

[The evaluation of the purity of medicinal oxygen]. / Otsenka chistoty meditsinskogo kisloroda.

Conditions are described of gaseous-chromatic analysis of inorganic mixtures contained in medical oxygen using chromatography with a detector of thermal conductivity. The relative error of determination does not exceed +/- 10%.

[Effect of ultraviolet irradiation on calcium, sodium and potassium levels in albino rats]. / Vliianie ul'trafioletovogo oblucheniia na soderzhanie kal'tsiia, natriia i kaliia v organizme belykh krys.

Data presented by the authors testifies to the fact that neither 2 weeks, nor one month after the 10-day course of ultraviolet irradiation (UVR) with an intensity from 1/4 up to 2 biodoses daily changes in calcium, sodium and potassium content in blood serum of laboratory animals (white rats) were detected. At the same time, 2 weeks following the cessation of UVR course a tendency towards calcium accumulation in the whole organism of laboratory animals was observed, which was most noticeable+ after daily 10-day exposure to UVR with an intensity from 1/2 up to 1 biodose. The tendency was still present one month following the termination of UVR course. The total sodium and potassium store in the whole organism of laboratory animals did not practically change either immediately, or 2 weeks, or 1 month after the termination of 10-day UVR course with the intensity from 1/4 to 2 biodoses daily.

[A toxicologic hygiene evaluation of electrolytic oxygen obtained from the water in a system with a solid polymeric electrolyte]. / Toksikologo-gigienicheskaia otsenka élektroliticheskogo kisloroda, poluchaemogo iz vody v sisteme s tverdym polimernym élektrolitom.

The authors evaluated the problems of hygienic aspects of oxygen obtained by the method of electrolytic decomposition of water with a different content of chemical substances in the system with a hard polymere electrolyte. On the basis of sanitary-chemical qualities and toxicological properties electrolysis gaseous oxygen may be recommended for use in creating an artificial gaseous atmosphere in hermetically sealed compartments in mixture with gaseous nitrogen (ratio 1:4).
