.... Mechanically increased hydrostatic pressure lowered perfusate sodium concentration, so that increased arterial pressure might have contributed to this aspect of high-dose angiotensin II effects. 6. These effects of angiotensin II might have physiological significance in relation to arterial smooth muscle...

... sodium chloride solution compared with the control kidney. The latter serves to maintain a non-azotaemic environment. 2. In the present studies, manoeuvres designed to alter predominantly either post-glomerular hydrostatic pressure (PGHP) or peritubular capillary oncotic pressure (COP) were performed...
