Summary
The effect of Malayan pit viper (Ancistrodon rhodostoma) venom on the fate of experimental arterial thrombosis was studied in rats. A suitable
daily dose of venom (500 μg) was used to induce hypofibrinogenaemia in the treated
rats for the greater part of each of three consecutive post-operative days.
The treated animals showed a statistically significant overall reduction in the incidence
of both red thrombus formation and thrombotic arterial occlusion when compared to
a control group. This antithrombotic effect of the venom could be observed in the
7-day period following the cessation of the treatment.
