摘要

We investigated blood flow response for reactive hyperemia test in type1 diabetic and control rats using diffuse correlationspectroscopy (DCS). The baseline blood flow, peak amplitude and time to peak blood flow responses after releasing fromischemia were significantly decreased after induction of hyperglycemic state in diabetic rats. Furthermore, the baselineblood flow and the peak amplitude were significantly decreased from 1st week to 10th week in diabetic rats, suggestingthe progress of vascular dysfunction caused by sustained glycemic stress. This research showed a potential of DCS todiagnose vascular function in diabetes that was altered by acute and chronic hyperglycemic stress.
