TY - JOUR T1 - VARIATIONS IN BLOOD PRESSURE INDUCED BY REPEATED INJECTIONS OF EXTRACTS OF THE POSTERIOR LOBE OF THE PITUITARY GLAND JF - Journal of Pharmacology and Experimental Therapeutics JO - J Pharmacol Exp Ther SP - 449 LP - 460 VL - 29 IS - 1 AU - E.

This "inversion effect" is accordingly not due to the presence of depressor bodies, as is maintained by Hogben and Schlapp. ER -
