Nephrotoxic effect of the specific brain serotonin depletor para-chlorophenylalanine.

Brain serotonin depletion induced by peripheral parachlorophenylalanine (pCPA) is frequently used to evaluate the role of the central serotoninergic system in the regulation of a number of physiological functions, including the secretion of renin by the kidney. We found that due to the treatments applied in the protocol used for the investigation of pCPA effect on renin and vasopressin secretion in rats (300 mg/kg i.p.
