[The effect of ionizing radiation on the resistance of rat pancreatic beta cells to streptozotocin].

Abstract

The effect of subliminal streptozotocin doses of rat pancreas cells was studied 1 and 3 months after 1-Gy gamma irradiation. Streptozotocin injected to irradiated animals caused a drastic decrease in beta-cell function which was manifested by hyperglycemia and less intensive secretion and lesser content of insulin in isolated pancreatic islands, as compared to control.
