Alloxan-induced diabetic rats were pretreated with β-adrenergic and cholinergic blockades, and then provided graded doses of norepinephrine by intravenous injections. The change in the blood pressure elevations was plotted as the pressor response. At each norepinephrine dose, both groups of diabetic animals had blunted pressor responses compared to the matched nondiabetic controls. Figure generously provided by Dr. R. D.
