Protective effect of vitamin C on endothelium-dependent arterial dilation in patients with impaired glucose tolerance during oral glucose loading / 中华内分泌代谢杂志

ABSTRACT

During oral glucose tolerance test(OGTT),endothelium-dependent vasodilation(EDD)at different time points in impaired glucose tolerance(IGT)group was lower than that in normal control group.EDD at 60 and 120 min in IGT + vitamin C group was higher than that in IGT group(all P＜0.05).There was a negative relationship between blood glucose level and EDD during OGTT in IGT patients.
