摘　　要：目的：由于电磁脉冲技术的广泛应用，暴露于电磁场中的人类健康可能受到影响，但一些特殊电磁波的生物效应，尤其是超宽带（ｕｌｔｒａ－ｗｉｄｅｂａｎｄＵＷＢ）电磁波生物效应研究较少，本实验应用培养淋巴细胞为模型，探讨其对细胞的损伤效应。方法：培养的淋巴细胞暴露于ＵＷＢ、峰值功率密度为１００Ｗ．ｃｍ－２，测定不同时间电磁波辐照后细胞死亡率和培养上清液中乳酸脱氢酶（ＬＤＨ）浓度变化。结果：ＵＷＢ电磁波辐照后细胞死亡率明显增高，培养上清液中ＬＤＨ浓度比正常对照显著增加，但两指标均不随培养时间变化而发生明显改变。As the technology of high peak power electromagnetic pulse is developed,it is necessary to evaluate it for health risks.In this study,lymphocytic death rate and the volume of lactic dehydrogenase (LDH) released by lymphocytes after exposure to 100W/cm 2 of peak density of ultra-wide electromagnetic pulse were investigated.It was found that both lymphocytic death rate and the volume of LDH increased immediately after exposure,and last for 20 hours.The changes suggest that ultra-wide band high peak power electromagnetic pulse injuries the cultured lymphocytes.
