title: [Prevention of galactose-induced cataractogenesis in rats by salvianolic acid A].
abstract: Salvianolic acid A has been demonstrated to have efficient antioxidative and free radical scavenging effects. In the present experiments, the preventive effects of salvianolic acid A on galactose-induced cataract in rats were investigated. Dropping 0.05% salvianolic acid A in the eyes (two times a day) was found to delay the development of cataract. The contents of MDA and H2O2 in the cataract lens were decreased in salvianolic acid A treated rats. The protein and non-protein thiols in the cataract lens of the salvianolic acid A treated rats were higher than those of control rats. In in vitro experiments salvianolic acid A was shown to inhibit aldose reductase activity. These results indicate that salvianolic acid A can prevent galactose-induced cataract by antioxidation and inhibition of aldose reductase.
