عنوان انگلیسی The effect of exposed to radiofrequencry emitted from jammer on the spatial memory
چکیده انگلیسی مقاله Introduction: The Widespread range of mobile phone application in life has induced many problems in the societies. This subject has caused jammer router is used in some places. Jammer router blocks signal transfer from base station to the cell phone. In the other hand, the extensive application of electromagnetic field in all aspect of life has increased fears and worries about side effects on the human healthy indexes, including learning and memory. Memory can be defined as the skill of saving the experiences and remembering the learned processes or events. This study was used Morris Water Maze Technique to test working spatial memory in rats after exposed to radiation emitted jammer. Materials and Methods: In this study, 50male rats (220-250g) randomly divided 5 groups (n=10): control, sham1&2, Experiment1&2. Experimental groups were irradiated through switched –on mobile phone jammer router2h/day once and other group 2h/day for two weeks' sequence. This procedure repeated for sham groups but with switched-off jammer router. The distance of animal cages from jammer antenna was 30cm. Learning ability and spatial memory were assessed by Morris Water Maze Technique Sham& Experimental groups were trained 4trails/day during 5 days. Then, data and parameters (latency time, path length) analyzed in different groups for founding the exposure radiation effect from jammer routers on the spatial memory in rats.   Results: The analyzed data did show the recorded mean from latency time to reach the hidden platform also the average of path length traveled to reach platform in one- day irradiated groups, as well as, among exposure groups during two weeks were significantly different relative to control. This means radiation emitted of jammer device have reduced learning level in exposure groups compare to control. However, duration exposure radiation 2h/day once or two weeks' sequence did not show significant difference on the considering parameters. In the other hand, duration exposure radiation 2h/day once or2h daily for two weeks' sequence did not show significant relationship on the spatial memory and learning performance. Conclusion: Exposure to jammer radiation was impaired spatial memory and learning abilities in exposure rats, but duration radiation did not show statistical significant effect on the learning performance and spatial memory.
