AIM: To study the effect of mobile microwave on the expression of Bax in the lens epithelial cells of rat in vitro.

METHODS: Bax expression was detected by ELISA and immunohistochemistry after the lenses of rats were cultivated in MEM culture medium.

RESULTS: The expression of Bax in the mobile microwave groups was significantly higher than the control group(P<0.05)and the expression of Bax accumulated while it was exposed in the mobile microwave.

CONCLUSION: Mobile microwave can induce the expression of Bax in the lens epithelial cells of rat and cause cataract.
