Renal atrial peptide receptors and natriuresis in two-kidney, one clip hypertension.
It has been suggested that the impaired natriuretic response of the clipped kidney in two-kidney, one clip hypertensive rats is related to downregulation of renal atrial natriuretic peptide receptors. To test this hypothesis, blood volume expansion and atrial peptide binding studies were performed in this model. Infusion of 1% and then 1.5% body weight donor blood (n = 6) caused a progressive i...
متن کاملRenal glomerular atrial natriuretic factor receptors in one-kidney, one clip rats.
One-kidney, one clip (1K1C) hypertension is often associated with an expanded plasma volume and (once the arterial clip is removed) with natriuresis. Blood pressure (BP), atrial and plasma concentrations of atrial natriuretic factor (ANF), hematocrit, and renal glomerular ANF receptors were therefore studied in 1K1C rats and in their normotensive uninephrectomized controls before and after uncl...
متن کاملTwo-Kidney, One-Clip Hypertension in the Rat
Baroreflex function was studied in conscious early phase (<6 weeks) two-kidney, one-clip hypertensive rats before and 24 hours after surgical reversal of hypertension by removal of the constricting renal artery clip or after pharmacological reduction of blood pressure by an infusion of hydralazine or captopril. A normotensive sham-clipped group was included. Another group of two-kidney, one-cli...
متن کاملRenal expression of aminopeptidase A in rats with two-kidney, one-clip hypertension.
BACKGROUND Angiotensin II (ANG II) is a major factor involved in the progression of chronic renal disease. Although the generation of this vasoactive peptide has been investigated in great detail, only a few studies have hitherto addressed the metabolism of ANG II into fragments such as angiotensin III and IV (ANG III, IV) which may exert physiological effects independent of ANG II. Aminopeptid...
متن کاملChemical renal medullectomy; effect upon reversal of two-kidney, one-clip hypertension in the rat.
1. Chemical renal medullectomy was produced in rats by injection of 2-bromoethylamine hydrobromide. Plasma creatinine and blood pressure were unchanged although urine volume was increased fourfold. 2. Left renal artery constriction resulted in similar degrees of hypertension in both intact and medullectomized rats. This was associated with a significantly smaller rise in plasma renin concentrat...
