Hexokinase and glucose-6-phosphate dehydro-genase were assayed in various circulating age-fractions i.e., young, middle-aged and old red cell from control, diabetic and insulin-treated diabetic rats. An increase in the activity of hexokinase was observed in three agewise separated fractions of red cells from diabetic animals in comparison to control. The activity of glucose-6-phosphate dehydrogenase on the other hand decreased in separated ageing fractions of diabetic red cells when compared to control. Reversal of these two enzymes were observed in insulin-treated diabetic rats. The levels of glycosylated haemoglobin and catecholamines were found to increase with ageing red cells in controls and also increased in red cells plasma.
