Investigation of antitumor substance from Trichoderma

The effect of L-lysine-α-oxidase from Trichoderma harzianum Rifai on the functional activity of T-lymphocytes was investigated. It was shown that in a dose of 35 units/kg administered parentally the enzyme had no suppressive effect on the T-lymphocyte functional activity. An inhibitory effect of L-lysine-α-oxidase on some indices of the macrophages functional activity was observed. L-Lyzine-α-oxidase had a selective lymphotropic action and showed no mytostatic activity, which is In favour of the enzyme vs. other antitumor agents.
