Anticataract Effects of Bendazac Lysine on Ultraviolet Induced Rat Cataract Based on Scheimpflug Camera

It has been known that ultraviolet B(UVB) light made an oxidative damage to lens proteins, lipids and nucleic acids to induce lens opacity. The aim of the study was to investigate the effect of bendazac lysine salt (Bendaline) tot the experimental cataract developed by UV irradiation. Forty rats were exposed to 0.1mW/cm2 of UVB radiation in the range 300-320 mm for 24 hours per day. Five control rats were not exposed UVB radiation. During the investigative period, we measured lens opacity with Scheimpflug camera every other week. Rats were divided into 9 groups according to the duration of UV radiation and initial time of bendazac lysine medication. Bendazac lysine was administered orally by 25mg/kg per day for 2 months. The opacities on anterior cortex, nucleus and posterior capsule began to appear 4 months after UVB irradiation. The longer duration of radiation, the more severe opacity of lens was observed, especially at the layers of posterior supranucleus, posterior cortex and posterior capsule and in the opacity area by retroillumination image. After UVB induced cataract was developed, the lens opacity was not changed nevertheless stop the UV irradiation. Lens opacity of bendazac lysine-treated groups was not severer than that of no medication groups. There were less opacities on 4 month irradiated group rather than 6 month irradiated group at the layers of nucleus and posterior cortex and in the opacity area. Anticataract action of bendazac lysine was effective in earlier cataract. In the group of bendazac lysine medication with UVB irradiation on same time, the prophylactic evidence of bendazac lysine was not observed.
