Abstract: | Alloxan diabetes causes a decrease in the active form of pyruvate dehydrogenase in rat brain. The effect is severe in the cerebellum and brain stem compared to cerebral hemispheres. The changes observed in the total form are not as significant as those found in the active (dephosphorylated) form. The effects are reversed after administration of insulin to diabetic animals. The severity of diabetes was also found to affect the activity of pyruvate dehydrogenase with inverse correlation. There was a gradual increase in the proportion of active (dephosphorylated) form with increase of time after the onset of diabetes. |
