The effect of Bitis gabonica venom administered intravenously in the rabbit at the dose of 0.125 mg/kg (approximately 10% of LD50) has been studied. Venom caused marked changes in cardiovascular parameters principally a precipitous but transient fall in total peripheral resistance and arterial blood pressure. Furthermore in the period occurring between 5 and 30 min after the injection of venom, a transient increase in stroke work was observed as a result of the ejection of an increased stroke volume against a blood pressure which had already returned to normal. Such a transient inotropic effect has also been observed in other small mammals and could be attributed to an adrenergic mechanism. © 1984
