[Effect of insulin on the amount of somatotropic hormone, immunoreactive insulin, blood sugar and free fatty acids in sheep].

Studied was the effect of the venous injecting of insulin at the rate of 0.2 IU/kg body weight on the changes in the amount of the somatotropic hormone (STH), the immunoresponsive insulin, the free fatty acids (FFA), and the blood sugar in the serum of sheep, following their dynamics up to the 150th minute after application. The STH level rose to its peak value at the 60th min., after which it showed a lowering trend. The level of FFA dropped sharply after the injection of insulin, its lowest value being registered at the 60th min., after which it rose. By the end of the experiment the blood values of STH and FFA were close to those of the control animals. The blood sugar level started to drop 30 min. following the injection of insulin, and up to the end of the experiment a hypoglycaemic reaction was observed.
