    Abstract:
    A study was made of the effect of experimental hyperinsulinemia, caused by daily administration of the increasing doses of a crystalline insulin-zinc suspension (up to 6 Units per animal) during 14 days, on the parameters of 125I-insulin binding by the insulin receptors of plasma membranes of adipose and liver tissues of intact rats and those with disturbed liver innervation. In intact rats, hyperinsulinemia led to the fall of the concentration of the insulin receptors and their affinity for insulin in the membranes of both tissues. In rats with disturbed liver innervation, analogous changes were observed for the receptors of adipose tissue, whereas the parameters of the receptors of liver were unchanged under the effect of hyperinsulinemia. It is concluded that nerve fibers that innervate the liver take part in the regulation of activity of the insulin receptors.
