【摘要】 研究了脉冲磁场与γ射线联合作用对ＨＬ６０细胞凋亡的影响。采用１３７Ｃｓ照射源剂量为４Ｇｙ，磁场强度为２０ＭＴ，频率为２５０Ｈｚ照射人早幼粒白血病细胞。结果表明，ＨＬ６０细胞经电磁场作用后，可以提高γ射线对它的杀伤效果，增加γ射线诱发ＨＬ６０细胞凋亡明显高于单独γ射线照射。更多还原

【Abstract】 With a view to examining the possible clinical applicability of pulsing electromagnetic fields (PEMF),the biological effects of PEMF and its combined effects with ionizing radiation on HL60 cells were investigated Cells were exposed to 4Gy gamma irradiation from a 137 Cs source The strength and frequency of PEMF were 20MT and 250Hz respectively The combined effect of 137 Cs irradiation with exposure to the PEMF showed a greater effect than a simple additive one The results suggest that PEMF can increase apoptosis induction of HL60 cells by inoizing radiation更多还原
