  • Title: Effects of a senso (toad venom) containing drug on systemic hemodynamics, cardiac function and myocardial oxygen consumption in anesthetized dogs.
    Author: Ojiri Y, Noguchi K, Sakanashi M.
    Journal: Am J Chin Med; 1991; 19(1):17-31. PubMed ID: 1897488.
    Abstract:
    Effects of a Senso (toad venom)-containing drug, KY, on cardiovascular system were examined in anesthetized open-chest dogs. KY increased aortic pressure, peak positive first derivative of left ventricular pressure, stroke work index, percent segment shortening in left ventricular myocardium and myocardial oxygen consumption, and decreased heart rate and total peripheral vascular resistance (TPR). Propranolol augmented the increase in aortic pressure with KY, inhibited the increase in aortic flow with KY and reversed KY-induced decrease in TPR to an increase. These results indicate that KY has positive inotropic and vasodilating actions possibly originating from both digitalis- and adrenaline-like action of a Senso.
