Effect of pH change upon renal vascular resistance and urine flow.
نویسندگان
چکیده
In the dog kidney, acute increase and decrease in hydrogen ion concentration results in decrease and increase in renal vascular resistance respectively. These changes occur predominantly on the alkaline side of pH 7.3 and result from some direct effect upon vascular smooth muscle. The resistance changes are less apparent in nerve intact than nerve sectioned kidneys due to opposing effects mediated through extrinsic nerves.

متن کاملEffects of acute renal denervation on kidney function in deoxycorticosterone acetate-hypertensive swine.
Deoxycorticosterone acetate-induced hypertension in Yucatan miniature swine appears to involve elevated peripheral sympathetic activity. Abnormalities in renal function in these hypertensive animals are also apparent. To determine the extent to which renal nerve activity controls kidney function in animals with established deoxycorticosterone acetate hypertension, the effects of acute renal sur...
متن کاملResults of Pyeloplasty in patients with Ureteropelvic Junction Obstruction in Pediatric Surgery Center in Bandar Abbas
Introduction: Ureteropelvic junction obstruction (UPJO) is associated with inadequate urine drainage from renal pelvis into ureter. UPJO results from incomplete recanalization of proximal ureter during fetal period which finally leads to hydrostatic distention of renal pelvis and calyces. Diagnosis is based on clinical symptoms, ultrasound, and diuretic isotopic renogram. Various surgical metho...

The contribution of alterations in renal hemodynamics to the diuretic and natriuretic actions of atrial natriuretic factor (ANF) was studied in chronically instrumented conscious dogs. Injection of ANF-(99-119), 10 micrograms/kg, had no effect on mean arterial pressure, heart rate, renal blood flow, or calculated renal vascular resistance; However, it increased urine flow rate (86 +/- 20%) and ...
