[Environmental monitoring in the foci of parasitic diseases in the town of Belgorod-Dnestrovsk, Odessa region]. / Monitoring za okruzhaiushchei sredoi v ochagakh parazitarnykh boleznei v gorode Belgorod-Dnestrovskom Odesskoi oblasti.

The paper shows a role of environmental objects in the formation of parasitic diseases in Belgorod-Dnestrovsk, developmental changes in intestinal parasitic cenoses in children from closed institutions. To attract parasitologists to the diagnosis of acute intestinal infections of unspecified etiology increases the percent (49.5 to 82.0) of positive results. The findings show what environmental objects should be monitored in the sanitary and parasitological contexts: soil, vegetables, greens in helminthiasis; utensils in preschool children' establishments in contact helminthiasis; drinking water, vegetables, greens in giardiasis.

[Effect of ionizing radiation on the chromatin fraction components in rat blood lymphocytes]. / Vplyv ionizuiuchoï radiatsiï na komponenty fraktsiï khromatynu limfotsytiv krovi shchuriv.

Changes in the level of blood lymphocyte chromatin degradation and relaxation were investigated after the whole body irradiation with doses up to 0.21 C/kg. It was shown that ionizing irradiation initiated the increase of nuclear endogenous Ca/mg-dependent endonuclease, and protease activities.

[Cyclic nucleotides in a high molecular weight aminoacyl-tRNA synthetase complex from the liver of normal and irradiated rats]. / Tsyklichni nukleotydy u skladi vysokomolekyliarnogo kompleksu aminoatsyl-tRNK-syntetaz iz pechinky normal'nykh ta oprominenykh shchuriv.

The content of cAMP and cGMP in the composition of the high-molecular complex aminoacyl-tRNA-synthetase from the rat liver has been studied. The ionizing radiation decreases the level of the cyclic nucleotides in the composition of the complex. A problem on interregulation of the cyclic nucleotides and prostaglandins in the complex has been examined.
