| To gain the effects of mobile phone microwave radiation in "call" position on developmental lens in chick embryo, microstructural, ultrastructural and macroscopic features of the developmental lens were observed by histological and histochemical methods and statistics. The results were as follows.(1) Compared with the developmental lens microstructure of the control groups, the fibrae lentis in the exposure group, to connect with the epithelium lentis, had been disrupted when hatched on 5th day. On 7th day, the results were similar to features of developmental lens of 5th day. Until 10th day, the fractures were more aggravated. Not only were the fibrae lentis disrupted but also they had slight vacuoles, and lens capsula were swelling till 15th day. Cellulae lentis aggravated vacuolization when embryos were hatched till 21th day.(2) Compared with the developmental lens ultrastructure of the control groups, the intercellular spaces and subcellular structures were normal when hatched till 10th day, but some of mitochondria in cellulae lentis cells were swelled or had disrupted crista. In addition, the quantities of endoplasmic reticulum reduced in the epithelial cells. On 15th day, a myriad of mitochondria membrane structures had been destroyed or vacuolar in fibrous lamina and the quantities of the endoplasmic reticulum in the epithelial cells were obviously reduced. On 21th day, all mitochondria were nearly damaged and the connection among the lens fiber cells occurred pathological change, where were liquor matters. The observation had shown from the ultrastructure, the 3h/d radiation doses induced the lens damages and these damages aggravated along with the development of chick embryos.(3) The more radiation dose was accumulated, the more serious turbidity of lens cortex was by the stereology observation on 10th,15th and 21th day developmental embryos. On the 10th,15th and the 21th day, the averages of lens weight and hydration level in the exposure group were higher than in the control group obviously (p<0.05). The 3h/d mobile phone microwave radiation energy(Frequency:900-1,800MHz, SAR:1.07W/kg) might induce the injury of tissue, microscopic structure and ultrastructure in lens, and then caused cataract. |
