Terrilytin and immobilized terrilytin enhance the activity and intensity of phagocytosis and increase the concentration of lysozyme in nonimmunized animals. Both preparations increase the production of antibodies to staphylococcal alpha-hemolysin, the titers of beta-lysins, the activity and intensity of the phagocytosis of bacterial cells by peripheral blood leukocytes in animals immunized with staphylococcal toxoid and challenged with live staphylococcal culture. In healthy animals terrilytin and immobilized terrilytin induce an increase in total proteolytic activity and in the activity of alpha-1-antitrypsin and alpha-2-macroglobulin, decreased as the result of staphylococcal infection.

The impact of proteolytic enzymes on the humoral immune response, survival rate and mean survival time of mice, infected with S. aureus culture and receiving antibiotics was studied. Infection with staphylococcal suppressed the formation of antibodies to sheep red blood cells.

As revealed in this study, massive burn trauma manifestly suppresses the genesis of antibodies to T-dependent antigen (sheep red blood cells). The administration of ampicillin to the burned animals enhances immunosuppression, while gentamicin produces no essential impact on immune processes under these conditions. Proteolytic enzymes, terrilytin and terridecase, have corrective influence on disturbances in immune response in animals with burns.

Joint immobilization of a proteolytic enzyme (terrilytin, protease C, or collytin) and an antimicrobial compound or the bacteriolytic enzyme lysozyme in the structure of polyvinyl alcohol was studied. Changes in the activity of immobilized enzymes upon x-ray sterilization were studied. These materials were highly effective in wound healing.

The influence of immobilized proteases such as catalytin (a complex preparation containing the protease terrilytin and the antiseptic catapol) and streptodecase (an activator of fibrinolysis proteases) on the humoral immune response induced by the thymus-dependent antigen (SRBC) under conditions of burns and Staphylococcus infected burns was studied. The immobilized proteases catalytin and streptodecase had an immunostimulating effect under conditions of extended burns. Catalytin had an immunocorrigating effect under conditions of the infected burns.

It was established that the molecule of anti-microbe substance containing a few base groups enhanced stability of the enzyme immobilized, most likely due to additional fixation of the enzyme macromolecule. Changes in activity of the materials containing both protease and anti-microbe compound were studied upon gamma-sterilization and subsequent prolonged storage.
