[The relationship between plasma atrial natriuretic peptide (ANP) and glomerular ANP receptors in 5/6 nephrectomized
Abstract:
Chronic renal failure was induced in male Wistar rats with 5/6 nephrectomy (group I) and sham-operation was carried in the controls (group II). The results showed that in group I, plasma ANP levels increased progressively as Scr elevated. The plasma levels of renin and angiotensin raised simultaneously as compared with the controls (P < 0.001). At the 20th week after operation, urine volume and Na decreased significantly (P < 0.05) and the number of glomerular ANP receptors decreased significantly at the 12th week (P < 0.05) and 20th week (P < 0.01). Our data suggest that in 5/6 nephrectomized rats: 1. The elevation of plasma ANP level might be partly caused by damage of glomerular receptors. 2. The elevated plasma ANP could not cause its diuretic, natriuretic, blood pressure depression and R-A inhibition effect due to the damage of kidney ANP receptors.
