[Effect of chronic gamma irradiation on dehydrogenase activity in the tissues of root voles and their progeny dwelling in a habitat with increased radioactivity].

Chronic gamma-irradiation during 3.5 and 6 months (at a dose = rate of 46.2 pC/kg X c) of Microtus oeconomus living in conditions of normal and increased (by 50-100 times) gamma-radiation background, and of their progeny (the 1st, 2nd, 3d, and 4th generations) causes in homogenates of cardiac muscle, liver, and brain different changes in activity of succinate dehydrogenase (1.3.99.1, EC), pyruvate dehydrogenase (1.2.4.1, EC), and lactate dehydrogenase (1.1.1.27, EC) associated with the discordance of the processes of tissue respiration and glycolysis. The changes in dehydrogenases activity in Microtus oeconomus subjected to chronic irradiation were nearly the same as those found in their parents.
