Chronic toxicity of the Iron (IV) clathrochelate complexes for white rats
The article presents the results of studies of chronic toxicity of the Iron in the rare unconventional valence – IV. During long-term use of the Iron(IV) clathrochelate complexes for white rats we have established the dynamics of the body weight of rats, the relative coefficients of mass of the internal organs, the content of hemoglobin and morphological parameters of blood, biochemical parameters of blood serum of animals of this species. The daily drinking of solution of the Iron(IV) clathrochelate complexes at the doses of 500 and 1000 mg/kg b. w. resulted in a decrease in body weight, an increase in the relative indices of masses of liver and kidney, and a decrease in the relative indices of masses of spleen and heart on 30th day. The hemoglobin content in the blood of rats of the experimental group was less than the control indicator by 3–47% (P < 0.05), which is evidence of inhibition of its synthesis under the influence of the Iron (IV) clathrochelatе. Changes in the morphological composition of the blood were characterized by marked leukocytopenia. The use of rats of a solution of the Iron (IV) clathrochelate complexes at doses of 500 and 1000 mg/kg b. w. caused the development of hypoproteinemia, hypercreatinemia and hyperurinemia. Iron(IV) clathrochelate complexes reduced alaninaminotransferase activity in the serum of rats of both experimental groups by 15–80% (P < 0.05); aspartataminotransferase activity increased significantly by day 10 and decreased by day 30; the activity of alkaline phosphatase was independent of the doses of the drug during the experimental period. The content of Calcium total, Phosphor inorganic and Iron in the serum of rats of the experimental groups was at the level of indicators in the animals of the control group. Consequently, comprehensive studies of the effects of solution of the Iron (IV) clathrochelate complexes at doses of 500 and 1000 mg/kg b. w. were performed for the first time with long-term administration to white rats, which revealed the main patterns of metabolic disorders and physiological functions.
