[Effects of insulin in vitro in the fatty tissue of rats with alloxan diabetes after insulin treatment or administration of insulin-like growth factors from human serum].

Insulin insufficiency in rats caused by alloxan, results in a decrease in the sensitivity of the fatty tissue to insulin determined by glucose oxidation and synthesis of lipids manifested in a decrease in a maximum response of the tissue to insulin. Multiple injection of insulin as well as of partially purified total fraction of insulinoid growth factors causes an increase in a maximum response of the fatty tissue to insulin and a right-hand shift of dose-response curves. The total effect of the injection of insulin or partially purified growth factors is expressed in elevated sensitivity of the fatty tissue to insulin.
