Key result
Endothelium-dependent relaxation produced by acetylcholine or A23187 was significantly attenuated in diabetic rat aortae compared to controls, while endothelium-independent relaxation was preserved.
Why the study?
Does diabetes impair endothelium-dependent relaxation in rat aortae?
Does diabetes impair endothelium-dependent relaxation in rat aortae?
Diabetes leads to a specific impairment of endothelium-dependent relaxation in rat aortae, highlighting a mechanism for vascular reactivity alterations in diabetes.

Endothelial impairment may underlie diabetic vascular changes in this model; leaves open translation to human disease and therapies.
Durante et al. (1988) studied Diabetes mellitus. Acetylcholine, A23187, sodium nitroprusside, adenosine vs. Control rats was evaluated on Endothelium-dependent and endothelium-independent relaxation in thoracic aorta. Endothelium-dependent relaxation produced by acetylcholine or A23187 was significantly attenuated in diabetic rat aortae compared to controls, while endothelium-independent relaxation was preserved.
