[Effect of alpha 2-macroglobulin on indices of the proteolysis system and organ blood flow in tourniquet shock]. / Vliianie al'fa 2-makroglobulina na pokazateli sistemy proteoliza i organnogo krovotoka pri turniketnom shoke.

It was shown that alpha 2-macroglobulin (50 mg/kg, 30 min before revascularization of previously ischemized extremities) significantly inhibits the blood serum proteolytic activity and exerts similarly to contrykal (10,000 U/kg) the correcting effect on the level of arterial blood pressure and parameters of the blood flow in the kidneys, intestine and previously ischemized extremities.

[Effect of kontrikal on the dynamics of proteolytic system indices in postischemic toxemia]. / Vliianie kontrikala na dinamiku pokazatelei sistemy proteoliza pri postishemicheskoi toksemii.

It was shown in Wistar male rats that the development of tourniquet shock was followed by an increase of proteolytic activity in the blood by 3 times, activity of aspartate aminotransferase (AST) by 3 times, that of alanine aminotransferase (ALT) by 6 times, contents of urea and residual nitrogen by 2.5-3 times; level of alpha 1-protease inhibitor (alpha 1-PI) decreased by 4 times and that of alpha 2-macroglobulin (alpha 2MG) by 2.5 times. At administration of contrykal (10,000 U/kg) proteolytic activity increased only by 32.5%, content of alpha 1-PI decreased only by 10-20% and level of alpha 2-MG did not differ from that in healthy animals. Activity of AST and ALT remained high, and contents of urea and residual nitrogen were near-normal.

[Effect of pancreatic kallikrein and trypsin inhibitors on the course of postischemic toxemia]. / Vliianie ingibitorov pankreaticheskgo kallikreina i tripsina na techenie postishemicheskoi toksemii.

By studying the ECG findings, dynamic changes of the body temperature, the edemas size in the tourniquet-compressed limbs, vascular permeability of the skin, general condition and survival rate on a model of post-ischemic toxemia in albino rats it was found that the serum containing antibodies to pancreatic kallikrein (200 gamma/ml), when introduced parenterally (1 ml per 100 g of the mass), increases the survival time of the animals and prevents the development of gangrene in the ischemic limbs. The curative effect of the antikallikrein serum resembles the action of ingitril, a polyvalent inhibitor (1.5 Un. per 100 g of the mass). The antitryptic serum employed in analogous doses stands by its action close to the normal rabbit's serum.
