The change in tonic renal efferent sympathetic nerve activity (RSNA) was studied during the rapid fall in mean arterial pressure (MAP) after surgical reversal of two-kidney, one clip hypertension in rats (RHR). Controls used were intact RHR exposed to the same fall in MAP induced by slow infusion of sodium nitroprusside. Within 2 h after declipping, MAP had fallen from 191 +/- 9 mmHg to 106 +/- 8 mmHg. During this decline in pressure, the reflex increase in RSNA, ordinarily following a decrease in pressure, was clearly suppressed; after a short and transient initial increase, RSNA was below the control level. In comparison, upon vascular dilatation with sodium-nitroprusside, the same fall in MAP was accompanied by a 117 +/- 30% increase in RSNA (P less than 0.01). Thus, the rapid normalization of MAP after reversal of renovascular hypertension involves a mechanism that exerts a suppressive action on the efferent sympathetic activity.
