Except such known inhibitors of proteolytic enzymes, as hirudin, bdellins and eglins, and also hyaluronidase enzyme, by us in a secretion of salivary glands of medical leeches the new enzyme destabilase which breaks isopeptide bonds in stabilized fibrin and having thrombolytic action, inhibitor of blood plasma kallikrein and prostanoids, on a spectrum of action similar to prostacycline and its stable analogues have been found. We show that the secret of leeches irrespective of presence in it hirudin suppresses platelet-vascular hemostasis, interfering adhesion of platelets on a surface of collagen and the aggregation of the platelets stimulated by inductors of various nature, by activation of adenylate cyclase of membranes of platelets [3]. Irrespective of the presence of hirudin, the secret blocks the contact stage of the internal mechanism of blood coagulation by inhibiting blood plasma kallikrein and Hagemann factor.
