Effect of oyster extracts on exercise -Glucide and lipid metabolism-

Abstract

In this study, we investigated about the effects of the oyster extract on the metabolism of the glucide and lipid in exercised rats. The oyster extract was prepared from Oyster ( Crassostrea gigas).

Wistar male rats of 4 weeks age were divided into 3 groups: (1) the normal diet with exercise (T-group), (2) the normal diet without exercise (C-group), and (3) the oyster extract added diet without exercise (O-group). After 4 weeks under these conditions, each group rats were forced to exercise. After the exercise, we analyzed triglyceride (TG), total cholesterol (TC), blood sugar level, lactate dehydrogenase (LDH), lactic acid, and free fatty acid in plasma, and also glycogen, TG, TC in liver.

The change of blood sugar level, LDH and lactic acid in T-group was less than those of the other groups. And the change of blood sugar level, LDH and lactic acid in O-group was less than that of C-group.
