Enhanced renal vascular reactivity in diabetic rats; hypothesis-generating for human diabetic nephropathy and requires clinical validation.
Does acetylcholine have an altered vasodilator effect in the renal blood vessels of diabetic rats compared to controls?
The study demonstrates an increased endothelium-dependent vasodilator response to acetylcholine in the renal blood vessels of diabetic rats, contrasting with previous findings of reduced EDRF biosynthesis in the aorta.
Bhardwaj et al. (1988) studied this question.
