SELECTIVE DEPLETION OF NORADRENALINE IN THE ADRENALS OF THE HAMSTER PRODUCED BY RESERPINE

Abstract
Following the administration of reserpine, 0.5 mg/kg, a complete depletion of yellow-brown pigment was found in the adrenal medulla of hamster tissue sections after oxidation with potassium iodate (Hillarp-Hofelt''s reagent, specific for norepinephrine). After oxidation with chrome salts, however, the cell groups located at the periphery of the medulla show no chromaffin, and only the central portion of the gland rich in epinephrine exhibits a chromaffin-positive reaction. These results suggest that in the dosage used, reserpine causes an almost selective depletion of norepinephrine in the adrenal medulla of the hamster.
