Effects of Long-Term Exposure to L-Band High-Power Microwave on the Brain Function of Male Mice

Figure 2

TUNEL staining of the hippocampus (CA1 and CA3) and cerebral cortex (S1) of mice after L-HPM exposure for different durations. Original magnification: ×400. (a) Representative image of TUNEL staining of the hippocampus and cerebral cortex after 4 weeks of L-HPM exposure (scale ). (b) Quantification of TUNEL-positive cells/mm² in the hippocampus and cerebral cortex after 4 weeks of L-HPM exposure. (c) Representative image of TUNEL staining of the hippocampus and cerebral cortex after 8 weeks of L-HPM exposure (scale ). (d) Quantification of TUNEL-positive cells/mm² in the hippocampus and cerebral cortex after 8 weeks of L-HPM exposure. Student’s -test, , , compared with the sham group. TUNEL: deoxynucleotidyl transferase-mediated dUTP nick-end labeling; L-HPM: L-band high-power microwave.
