The effect of Bitis gabonica (gaboon viper) snake venom on blood pressure, stroke volume and coronary circulation in the dog.
The effects of Gaboon Viper (Bitis gabonica) venom on cardiac output, arterial blood pressure, coronary flow and total peripheral resistance were investigated in eight anaesthetized dogs. Venom dosesExpand

The effect of the coronary vascular wall on the changes in the coronary vascular resistance during a sudden reduction and recovery of the aortic blood pressure.
To demonstrate the effect of elastic and myogenic properties of the vessel wall on the mean coronary vascular resistance during ventricular diastole (m.d.c.r.), this resistance was assessed in twentyExpand

The effect of Bitis gabonica (Gaboon viper) snake venom on external iliac and mesenteric arterial circulation in the dog.
The effects of Gaboon viper (Bitis gabonica) venom on external iliac and mesenteric arterial blood flow and resistance were investigated in eight anaesthetized, close-chest dogs. Venom doses in theExpand

The effect of gaboon viper (Bitis gabonica) venom on cardiac stroke work in the anaesthetized rabbit.
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 cardiovascularExpand

Simple physical model of coronary vasodilation.
The coronary diastolic pressure-flow relationship was studied in two groups of dogs; in one group coronary circulation was characterized by normal tone of vascular smooth muscle, while in the otherExpand

Systolic and diastolic changes in human coronary blood flow during Valsalva manoeuvre.
Valsalva manoeuvre is reported to be sometimes successful for the relief of angina pectoris. The present study investigated how haemodynamic changes produced by Valsalva manoeuvre can interact toExpand

Effect of tachycardia and constriction of left circumflex artery on coronary flow and pressure in anaesthetized dogs.
1. The effect of graded changes in heart rate between 100 and 160 beats/min and constriction of the left circumflex coronary artery which reduced coronary blood flow was examined in sevenExpand

Cardiac performance in the rabbit as affected by the venom of bitis gabonica. (A preliminary report).
The effect of the venom of Bitis gabonica administered intravenously in the rabbit at the dose of 0.125 mg/kg has been compared with that produced by the same dose of the compound in the dog. In theExpand

The effect of the venom of Bitis gabonica on mesenteric and external iliac blood flow. - A preliminary study in the dog.
The activity of the venom of Bitis Gabonica on mesenteric and external iliac circulation was investigated in four anaesthetized dogs. Venom doses of 0.125, 0.25 and 0.50 mg/kg were injectedExpand

Haemodynamic effect of the venom of Bitis Gabonica in the dog.
Intravenous injection of 0.125 mg/kg of venom of Bitis Gabonica in the anaesthetized dog produces an immediate but reversible decrease in total peripheral and coronary vascular resistance. StrokeExpand
