The effect of 4-aminopyrazolo (3,4-d) pyrimidine (4-APP) on some parameters of carbohydrate metabolism in the rat.
The study was designed to evaluate some parameters of carbohydrate metabolism in the rat as influenced by 4-APP, an adenine analogue. Adult female rats were injected with 1 mg 4-APP/100 g body weight/day for 3 days. 4-APP evoked a marked enlargement of the liver with lipid droplets accumulation in hepatocytes. This was accompanied by a marked lowering of the liver glycogen content. Within 3 days 4-APP did not change serum glucose, insulin and free fatty acid concentration. Serum glycogenolytic activity studied in an in vitro system showed 7 times as high glucose releasing ability in 4-APP treated rats as that of the serum of control animals. 4-APP resulted also in a marked enlargement of the adrenal medulla and lowered adrenaline and noradrenaline concentrations in the gland. The possibility of an activation of glycogenolysis in the liver of 4-APP treated rats has been discussed.
