Rats were sampled for clearance studies under anesthesia after 0, 2, 4, 7 and 14 days of dietary protein restriction. Mean fractional urea excretion decreased between day 2 and day 7 of protein restriction after a two-day lag in response. Seven-day administration of dexamethasone in protein-restricted rats caused a significant increase in mean fractional urea excretion. Adrenalectomized rats fed a normal diet had fractional urea excretion values resembling those in protein-restricted rats. Chronic administration of dexamethasone in adrenalectomized rats caused a consistent increase in fractional urea excretion. Fractional urea excretion values were no lower in protein-restricted adrenalectomized rats fed a normal diet. The mean plasma corticosterone concentration (measured 6 to 8 PM) was decreased in rats fed a low protein diet relative to rats fed a high protein diet. The results suggest that glucocorticoids may play a role in the tubular regulation of urea excretion either by a direct effect on the renal tubule or through some intermediate factor. A mediating role of glomerular filtration rate in glucocorticoid-induced changes of fractional urea excretion could not be ruled out, however.
