Acute and chronic effects of insulin on lactate dehydrogenase (LDH) activity in tissues of albino rat (Wistar strain).
Male albino rats were treated with insulin for one week (acute) and four weeks (chronic). The lactate dehydrogenase (LDH) activity, lactate and pyruvate levels were estimated in the tissues of experimental and control animals. LDH activity decreased in all the tissues of acute- and chronic treated animals whereas the lactate content is elevated. Pyruvate content also showed increment except in heart and pancreas with reference to acute treatment where it is decreased. The hyperinsulinaemia effect in relation to lacticacidaemia and its influence on energy demand and ammonia secretion is discussed.
