Effect of aldose reductase inhibitor on the inhibition of platelet aggregation induced by diabetic rat plasma

Abstract

Plasma isolated from streptozotocin-induced diabetic rats inhibited platelet aggregation. Treatment of diabetic rats with an aldose reductase inhibitor, ONO-2235, which did not improve hyperglycemia, prevented the antiaggregating activity of plasma as did insulin treatment. Both treatments reduced the elevated sorbitol concentrations in erythrocytes. Although the factor(s) accounting for the antiaggregatory effect of diabetic plasma has not yet been characterized, it is possible that the accumulation of sorbitol in erythrocytes is related to the generation of the factor(s).
