Effects of Mobile Telephone Microwave Radiation on Learning and Memory of Mice

SONG Xin-yang, TAN Li, YANG Zhong-tang, et al. Basic Medical College, Shanghai University of Traditional Chinese Medicine, Shanghai 201203, China  
Objective To study the effects of mobile telephone microwave radiation on learning and memory of young and senile mice. Methods The young(5 months old) and senile(10 months old) male Kunming mice were randomly divided into 2 groups respectively, the control and exposed. The young and senile mice were settled in the environment of the mobile telephone signal shoots station (3 V/m) and exposed to the mobile telephone conversation radiation with two mobile telephones for 5 h/d for 50 consecutive days. The control group was in the environment without microwave radiation (0 V/m). The capability of learning and memory of each group were determined by Morris maze test(the time of finding the flat roof:the latency), the activity of acetylcholinesterase (AchE) in the hippocampus and temporal lobe were measured by spectrophotometry. Results With the increase of training time, no significant decrease of the latency was seen in each group. Compared with the senile control group, the activity of AchE in the hippocampus and temporal lobe of the young control group and the senile radiation group were lower(P0.05). Compared with the young control group, the activity of AchE in the hippocampus of the young radiation group was higher(P0.05). Conclusion Mobile telephone microwave radiation may have little impact or have a positive impact on the learning and memory ability in the senile mice, but it may have an adverse effect in the young mice.
