Immunohistochemical profile of corneal tissue with HSK. In active keratitis, strong TCTP staining was observed throughout all layers of the corneal epithelium, as well as in stromal cells (A-B), whereas in quiescent disease little or no expression was present (A, inset) [A, O.M 10x; B, O.M. 20x; inset, O.M. 20x].
