[Corneal lysosomes in experimental ophthalmoherpes].

Activity and intracellular distribution of lysosomal glucosidases (beta-glucosidase and beta-galactosidase) of the cornea as well as membrane permeability were studied in experimental herpetic keratitis. It was demonstrated that the action of herpes simplex entailed labilization of the lysosomal membranes of the cornea together with the decreased strength of lysosomal association with the enzymes thereby favouring the increased enzyme-substrate contact and excess destruction of cellular and exocellular glycosaminoglycans. The data obtained suggest that lysosomes participate in the pathogenesis of herpetic keratitis.
