Impacts of high power microwave radiation on the apoptosis of testicular germ cell in the rat / 医学研究生学报

ABSTRACT

Objective:To study the impacts of high power microwave radiation on the testicular germ cell apoptosis in the rats. Methods: Fifty Spraque-Dawley rats were randomly divided into two groups .In the experimental group,the animals were radiated with S wave band 20 mW/cm 2 high power microwave for 5 min, and in the control group,5 rat were not radiated. 5 blank radiation groups served as controls. At the end of process, testicular germ cell apoptosis were detected by in situ terminal deoxymudeotityl transferase mediated dUTP nick end labeling (TUNEL) 6 h , 24 h, 48 h, 72 h and 5d following radiation. Results:In experiment group the amounts of apoptosis cells were more than that of control group 6 h?24 h?48 h following radiation(P0.05). Conclusion: Radiation by HPM for 5 min would result in testicular germ cell apoptosis and damage in the rat.
