[The role of thyroid hormones in the regulation of electric stability of erythrocyte membranes in rats].

A method of electric breakdown was used for a study of electric stability (durability) of the membranes of erythrocytes isolated from the blood of normal rats and rats with hypo-, hyperthyrosis and thyrotoxicosis. Erythrocytic membrane electric durability was shown to depend on the hormonal status. In particular, an increase in the potential of breakdown of erythrocytes of hyperthyroid rats was shown in comparison with the characteristics of erythrocytes of the other studied populations. Judging by the test thyrotoxicosis was accompanied by a decrease in a degree of physical homogeneity of erythrocytic membranes. There were no differences in electric durability between erythrocytes of normal and hyperthyroid animals.
