| Abstract: | Hemostatic properties of extracts isolated from the birch floscules and willow blossoms have been revealed. An agent of thromboplastic nature which is identical to thromboplasin of the rat brain according to its biochemical composition and procoagulative action has been found in these extracts. In contrast to brain thromboplastin thromboplastic activity of plant extracts does not possess the species specificity. After intravenous injection of the plant extracts a reaction similar to defence reaction of the anticoagulation system in response to thromboplastin infusion of the rat brain develops in rats. |
