ObjectiveTo study the protective effect of resveratrol on lens epithelial cell apoptosis in diabetic cataract rat.MethodsA total of 84 Wistar rats were divided into 4 groups: 12 in Group A (control group), 24 in Group B (diabetic cataract group), 24 in Group C (therapeutic–dose of resveratrol group) and 24 in Group D (low–dose of resveratrol group). Rats in Group B–D were given with 60 mg/kg streptozotocin through intraperitoneal injection. Rats in Group C were given with 100 mg/kg resveratrol and rats in Group D were given with 20 mg/kg resveratrol. The caspase–3 expression levels and apoptosis ratios of LEC among each group were observed; the degrees of lens opacity in Group B–D after 12 weeks were compared.ResultsThere were significant differences in caspase–3 expression levels, apoptosis ratios of LEC among groups at 4 w, 8 w and 12 w (P<0.05). After 12 weeks, in Group B the degree of lens opacity was as follow: 0 (0.00%) in grade I, 3 (37.50%) in grade II, 2 (25.00%)in grade III, 2 (25.00%)grade IV, and 1 (12.50%) in grade V; in Group C: 2 (25.00%)in grade I, 4 (50.00%) in grade II, 2 (25.00%)in grade III, 0 (0.00%)grade IV, and 0 (0.00 %) in grade V; in Group D: 1 (12.50%)in grade I, 4 (50.00%) in grade II, 2 (25.00%) in grade III, 1 (12.50%) grade IV, and 0 (0.00%) in grade V. The difference among Group B–D was statistically significant (P<0.05).ConclusionsResveratrol has protective effect on lens epithelial cell apoptosis in diabetic cataract rat, and the effect is relative to its dose.
