[Renal extraction of para-aminohippurate and inulin from sheep on low-protein diets].
In sheep fed low-protein diets, renal PAH and inulin extractions are not affected by the fall in plasma urea level or in the renal plasma flow itself. The noted reduction in glomerular filtration rate is not due to a preglomerular shunt of arterial blood since the filtration fraction does not vary by comparison to sheep on regular diets. Thus, the reduction in renal plasma flow (PAH clearance), induced by low protein rations, is not dependent on any change in PAH extraction. This reduction is probably responsible for the simultaneous decrease of glomerular filtration.
