Summary In the previously published studies a statement was made that the physiological anticoagulating system was present not only in the mammals, but also in amphibians. The present paper deals with experiments on frogs showing that after bilateral division of the vagus roots arising from medulla oblongata, the animals died of thrombosis resulting from intravenous injection of thrombin (moderate doses −0.3–0.4 ml). However, following bilateral extirpation of sympathetic ganglia II and III no thrombosis occurred upon injection of similar doses of thrombin. Therefore, closure of the reflex arc of the physiological anticoagulating system is located in amphibians (as in mammals) in the sphere of medulla oblongata-vagus nuclei: protective response of the anticoagulating system is controlled by the cranial part of the parasympathetic nervous system.
