[Production of fibrous materials, containing an immobilized proteolytic enzyme and urea]. / Poluchenie voloknistykh materialov, soderzhashchikh immobilizovannyi proteolitichskii ferment i mochevinu.

Immobilization of cellulose and polyacrylic acid on a grafted copolymer increased significantly the stability of proteolytic enzymes to inactivation by urea. Materials containing immobilized proteolytic enzymes and urea and displaying a combined biological activity were obtained.

[Preparation of films with combined biological activity and study of their properties]. / Poluchenie plenok s kombinirovannym biologicheskim deistviem i issledovanie ikh svoistv.

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.
