Effects of a natural complex of cytokines secreted by peripheral blood leukocytes on the healing of perforating wounds of the cornea were studied in 28 rabbits (14 animals in control and 14 in experimental groups). The process of healing of similar cut wounds of the cornea during local application of cytostatics was assessed by morphological and morphometric methods on days 1, 3, 7, 14, and 30 after the injury. Two periods, early and late, were distinguished in the morphogenesis of healing of a cut wound of the cornea under the effect of natural cytokines. The cytokines enhanced neutrophil migration to the wound canal in the early period of morphogenesis, this accelerating fibrin resorption, which was followed by filling of the wound canal with keratoblastic proliferate. In the late period of morphogenesis of wound healing (days 14-30) the functional activity of fibroblasts was increased, this being conducive to activation of collagenization of cicatricial tissue and resorption of the cicatrix as a result of a possible increase of collagenase release under the effect of cytokines. The possible mechanism of regulating effect of cytokines on corneal repair is discussed.
