This study was carried out to prove the therapeutic effects of BNJB on the catract. The objects of this study were CXSD mice that spontaneously eye rupture occurred from three weeks after birth and eventually generate cataract within 12 weeks. We applied eyewash made from BNJB to eyes of CXSD mice twice in a day till all the eyes of the negative control showed up the symptoms of a cataract and recorded the increasing patterns of cataractous eyes. To explained the therapeutic effects of the BNJB, We carried out the ex vivo experiment which cultivating eyeballs were offered oxidative stress condition by 0.03% H2O2 during three days. Total co-enzyme was extracted from the cultured eyeballs and used to measure activities of catalase, superoxide dismutase, glutathion S-transferase and content of GSH. The results were obtained as follows: 1. When we treated the catalin to CXSD mouse as a positive control, it represented the delaying effect for cataract generation for 2-3 days compare with negative control. But it seems that it doesn't appropriate as a therapeutic, or delaying agent. 2. In the experimental BNJB group, Cataract formation rate was dramatically reduced by BNJB. This rate was much lower than positive group and means our new formulation for the therapy of cataract has a good potential. 3. In the analysis of individual medicines of BNJB, Mok-Jeok-Cho, Hwang-Lyun and Ha-Go-Cho didn't have a major effect of BNJB. 4. The cataract formation rate was repressed by Bing-Pyun and Jin- Joo-Boon about 40% and 50%, respectively. We can presume that the anti-cataract effect of BNJB was caused by these two medicines. 5. When we surveyed the anti-oxidant activities of BNJB, enzyme activities of GSH, SOD, and Catalase increased about 10%,30%, and 2.5 folds, respectively.
