[Comprehensive hygienic assessment of environmental pollution in rural localities in the area affected by the Orenburg gas processing plant].

Comprehensive analysis of environmental pollution was made in 15 rural settlements of Orenburgsky and Perevolotsky districts located in the vicinity of gas-processing works. The ambient air, the blanket of snow, and drinking water were assessed for pollution. The drinking water and ambient air in vicinity of the works were found to be polluted by toxic substances.

[Chemical nature and biological activity of miliacine].

Chemical nature and biological activity of miliacine that is contained in millet oil have been studied. It produces moderate anti-inflammatory effect, stimulates sexual resistance in female rats, increases summary gonadotropic activity of the hypophysis in infantile female rats; in case of acute intoxication with carbon tetrachloride, it promotes normalization of enzyme activity in the liver and blood serum. Miliacine is of practical importance in meat cattle breeding as a growth stimulator.

[New food dye from sorghum grain hull and its toxicological characteristics].

The chemical composition and biological action of a new food dyestuff separated from the grain sorhum film were studied. From 1 kg of the grain sorhum 169--248 g of the film are retrieved; and from this it is possible to obtain from 17 to 40 g of a flavonoid dyestuff that consists of cyanadine, quercitrol and pelargonidine. The dyestuff can be utilized in the food industry in preparing bisquit cream products, caramels and fruit starch jellies.
