Importance of the renal nerves in established two-kidney, one clip Goldblatt hypertension.

Importance of the renal nerves in established two-kidney, one clip Goldblatt hypertension.

Increased sympathetic nervous system activity has been demonstrated in established twokidney, one clip hypertension in the rat. To determine the importance of the renal nerves in this model of hypertension, renal denervation of the clipped kidney (n = IS), renal denotation of the nondlpped kidney (n = 14), sham operation (n = 20), or undlpping (n = 12) was carried out 6 weeks after the onset of...

Role of the renal nerves in one-kidney, one clip hypertension in rats.

The effects of renal denervation on the onset and maintenance of one-kidney, one clip Goldblatt (1K1C) hypertension were determined. Renal denervation was performed at the time of 1K1C surgery, and was repeated at 3-week intervals to prevent renal nerve regeneration. Denervation delayed the onset of 1K1C hypertension by about 5 weeks, but the final hypertensive state was unaltered. Mean arteria...

Dietary potassium and the development of hypertension in two-kidney, one clip Goldblatt hypertensive rats.

Intrarenal adenosine produces hypertension via renal nerves in the one-kidney, one clip rat.

The afferent renal nerves enhance sympathetic activity in the one-kidney, one-clip hypertensive rat. We have also found adenosine-sensitive nerve endings in the renal pelvis that, when stimulated, increase sympathetic activity producing hypertension. To determine whether adenosine, which is excreted when renal blood flow is reduced, activates the afferent renal nerves in one-kidney, one-clip hy...

Regression of left ventricular hypertrophy in two-kidney, one clip Goldblatt hypertension.

The effect of regression of left ventricular hypertrophy (LVH) on ventricular performance was studied in two-kidney, one clip Goldblatt hypertensive rats (2K1C) treated with methyldopa or by unclipping. Sham operations were performed in a total of 21 rats; 12 and nine were studied after 4 and 6 weeks, respectively. Hypertension was induced in 38 additional rats. Of these, 11 were studied at 4 w...
