[Hemostatic changes after local exposure to low temperatures (frostbite)].
Hemostatic blood potential was studied in experiments on 400 rats, 25 dogs and in 120 patients, during changes of CNS reactivity after intraventricular injection of reserpine, adrenaline, and irritation of the thalamus ventromedial nucleus (VMN) or its destruction. CNS reactivity in dogs changed after intraarterial injections of acetylcholine, reserpine, heparin and fibrinolysin solutions. It was shown that activation of adrenergic structures of the hypothalamus by intraventricular adrenaline injections, or the hypothalamus VMN irritation, stimulated coagulation and depressed anticoagulation mechanisms of the blood, and increased hemostatic blood potential, that led to rejection of frostbitten tissues. Activation of the hypothalamus cholinergic structures by intraventricular injections of reserpine, destruction of the hypothalamus VMN, and intraarterial injections of acetylcholine, reserpine, heparin, fibrilysin and contrycal mixtures stimulated the blood anticoagulation mechanisms, decreased the hemostatic potential, led to retention of cryodestructed tissues.
