Abstract

Bilateral cervical vagotomy in ten anesthetized dogs did not alter quantitatively the hypotension resulting from intravenous infusions of ester alkaloids of veratrum. Germitrine, protoveratrine, germidine, germerine and veratridine were tested. The alkamine, veratramine, produced the same result. The ten-minute infusions of these agents caused average decreases in mean arterial blood pressure of 25 to 45 per cent.
