Abstract

Effect of cell phone radiation on neutrophil of mice Pei Y, Gao H, Li L, An X, Tian Q. Effect of cell phone radiation on neutrophil of mice. Int J Radiat Biol. 2019 Apr 23:1-22. doi: 10.1080/09553002.2019.1607605. Abstract Purpose The present study aims to evaluate the effect of cell phone radiation on neutrophil of mice. Materials and methods 40 male BALB/C mice were randomly broken up into 4 groups as control, blank control, TD-CDMA and LTE-Advanced groups respectively. Mice were exposed to cell phone radiation for a period of 6 weeks. Then numbers of neutrophil were detected by fully automatic haematology analyzer. Soft agar diffusion method was performed to assess the chemotaxis of neutrophils while the phagocytosis of neutrophils was determined by measuring the staphylococcus albus phagocytosis percentage. Apoptosis was analyzed by flow cytometry. Results No significant differences were observed among the control and exposure groups regarding the numbers of neutrophils after 2 weeks' exposure to cell phone radiation, while the numbers of neutrophils in TD-SCDMA and LTE-Advanced groups were seen to rise after an exposure of 4 or 6 weeks. No effect was observed on chemotaxis of neutrophils due to phone radiation. The phagocytosis of neutrophils was decreased while the apoptosis were increased both in TD-SCDMA and LTE-Advanced groups after 6 weeks exposure. Conclusions Mobile phone radiation could give rise to increase of neutrophil numbers yet with no effect whatever on neutrophils chemotaxis, and the radiation was likely to cause decrease of phagocytosis and induced apoptosis of neutrophils. ncbi.nlm.nih.gov
