Approaches to Reducing the Risk of Toxic Effects on the Population of Young Sheep - Abstract
This article presents the results of pathological-anatomical and histological features of organs and tissues of young sheep, studied from peasant farms of Karsakpayskiy county of Ulytau district in Karaganda region in the area of emergency falling of “Proton-M” expendable launch system, and after a possible heptyl intoxication of animals.
The authors conducted experiments to study the pathoanatomic and histological picture of organs and tissues of young sheep affected by asymmetric dimethylhydrazine (UDMH). This highly toxic fuel was spilled on the territory of the Karsakpai and Ulytau districts of the Karaganda region, Kazakhstan, due to the fall of the Proton-M rocket after an unsuccessful launch from the Baikonur cosmodrome in 2007. In the experiment, the study group consisted of 10 young sheep that grazed in the zone of possible poisoning with UDMH rocket fuel. The main objects of the study were histological preparations obtained from “fixed structures” - living and dead cells and tissues. Since the structures have a flat contrast and are poorly detected in a conventional light microscope, specially treated preparations were used. After preparation, the authors xamined organs and tissues using a microscope, which allowed to reveal in detail the level of damage caused by intoxication of the obtained pathological materials (parenchymal organs and blood).v
