Effects of collagenolytic protease preparations from invertebrates on the immune system

We studied the effects of an active ingredient of new enzyme preparations containing collagenolytic proteases from various hydrobionts (Collagenase from hydrobionts, Polycollagenase-K, and Fermenkol). These substances in therapeutic doses did not affect the humoral immune response estimated by hemagglutination and local hemolysis in gel and caused no local irritation and allergic reactions after long-term application to the skin.
