[Islet function of the pancreas following irradiation].

Function of islets of Langerhans of Wistar male rats was studied after irradiation of animals with different doses. The pancreas function was determined with regard to the incorporation of 65Zn into the gland tissues. Total-body irradiation (60Co) with the dose of 4.0 Gy somewhat increased the function of islets; at the dose of 8.0 Gy their function was transiently blocked, and at the dose of 15 Gy the function of islets of Langerhans was blocked completely.
