OBJECTIVE To investigate the role of caspase-3 and its inhibitor Ac-DEVD-CHO in rat lens epithelial cell apoptosis induced by hydrogen peroxide (H(2)O(2)) in vitro. METHODS Rat lenses were incubated in modified Eagle's medium containing 2 mmol/L H(2)O(2) to induce apoptosis in vitro. Apoptosis in lens epithelial cells was assessed by transmission electron(More)
OBJECTIVE To investigate the expression of vascular endothelial growth factor (VEGF) in rat cornea after cautery with alkali. METHODS In Sprague-Dawley rats, inflammatory corneal neovascularization was induced by cautery with alkali. VEGF was detected in corneal samples at different times by Western-blot, and immunohistochemistry method was used to(More)
BACKGROUND To investigate the molecular defects in a four-generation Chinese pedigree affected with Thiel-Behnke corneal dystrophy (TBCD). And to further study the relationship between genetic mutation and clinical manifestations. METHODS Individuals of the pedigree were recruited for extensive ophthalmic examinations. Histological studies of two corneal(More)
The scarcity of corneal tissue to treat deep corneal defects and corneal perforations remains a challenge. Currently, small incision lenticule extraction (SMILE)-derived lenticules appear to be a promising alternative for the treatment of these conditions. However, the thickness and toughness of a single piece of lenticule are limited. To overcome these(More)
OBJECTIVE To study the expression and role of calpain II in rat lens epithelial cells (LECs) of hydrogen peroxide (H(2)O(2))-induced cataract. METHODS Rat lenses were cultured in vitro and cataract was induced by 2 mM H(2)O(2). The lenses were observed under microscope. Simultaneously, photographs and picture analyses were done in order to detect the(More)
