Research Abstract

There was no significant difference in body weight and food intake between D group and A group till 52 weeks. GTT at 25 weeks showed that blood glucose at fasting and 30 minutes in D group were significantly increased and insulin level at 30 and 60 minutes were also significantly increased, but not in A group. Hindlimb muscles in D group at 25 weeks showed siginificant decrease of muscle weight and reduction of Akt phosphorylation, but not those in A group. The body weight of D group decreased at 98 weeks, but that of A group was maintained. GTT at 98 weeks showed that the insulin level in A group was maintained, but not in D group.
From these results, Asx supplementation of before onset of type 2 diabetes transiently improves insulin resistance and attenuates atrophy, and that maintains Akt phosphorylation in muscles. Long term Asx supplementation conserved insulin secretory function for OLEF rats.
