Rabchenyuk O. Influence of increased concentrations of Ferum in water on metabolic processes in the organism of carp and pike

The work deals the role of some links of protein-nucleic and lipid metabolism in the organism of carp and pike in adaptation to the action of elevated concentrations of Ferum ions in water environment is illustrated. It is show, that the accumulation of iron by fishes is tissue-specific process. The growth of the amount of RNA in the carp liver and muscle of the pike and the decrease of its content in the liver of pike and carp at increased concentrations of Ferum ions has been established. The amount of DNA is reduced in the liver of carp and muscle of the pike with the action of both investigated concentrations of Ferum ions and increases in the liver of the pike and carp muscle. Changes in the ratio of RNA/DNA and the numbers of metabolic activity under the action of iron ions indicate an intensify in genome expression and biosynthesis of proteins. It is noted that in the liver and in the blood serum of carp changes of alanine and aspartateaminotransferase were directed to rebuilding on aminoacid and protein metabolism in order to provide energy and plastic adaptation to the stress-action of the toxicant.
