Resting and Exercise Hyperemic Pulsatile Arterial Blood Flow in Insulin-dependent Diabetic Subjects

60 subjects aged 18-30 years with no clinically detectable peripheral vascular disease, comprising 20 normal controls, 20 short-term insulin-dependent diabetics (mean duration 5.17 yr), and 20 long-term insulin-dependent diabetics (mean duration 14.76 yr).
