Figure 8. Immunohistochemistry staining of PCNA, 10×40 magnification.

A: 3d group control eye, dark brown granules deposits in nuclear of cells either in epithelial or subconjunctiva fibroblasts; B: 14d group control eye, dark brown scattered in different layers cell nuclear; C: 21d group control eye with dark brown nuclear mainly in epithelial cells; D: 28d group control eye; E: 3d group olmesartan treated eye with less brown granules in nuclear; F: 14d group olmesartan eye with less PCNA positive cell nuclear; G: 21d group olmesartan eye with milder brown and less positive cells; H: 28d group olmesartan eye lighter brown granules.
