Fig. 5.

(A) Showing the epithelial cells is formed of basal layer (↑), intermediate polygonal cells (^*) and superficial flat cells (↓↓). Notice, regular arrangement of the collagen fibers in the stroma (c). (B) Showing the thickness of the Descemet’s membrane (↓) nearly similar to control group. (C) Showing an apparent increase in the number of alkaline phosphatase positive cells in the substantia propria (↓). (D) Showing brown cytoplasmic positive reaction of CD44 in some superficial epithelial cells (↓). (E) Showing an apparent increase in the number of vimentin positive cells in stroma. Notice the strong intensity of their reaction (↓). Subgroup IIIb ; A=H&E×560, B=PAS×560, C=Alkaline phosphatase reaction×250, D=Avidin–biotin peroxidase for CD44×560, E=Avidin–biotin peroxidase for vimentin×250.
