摘　　要：本文采用２４５０ＭＨｚ低功率微波辐射离体人红细胞，从分子水平研究微波对红细胞膜的影响。选择功率密度为０ｍＷ／ｃｍ２，５ｍＷ／ｃｍ２，１０ｍＷ／ｃｍ２，辐射时间为３０ｍｉｎ，结果显示，１０ｍＷ／ｃｍ２的微波对离体人红细胞有较为明显的损失。表现为红细胞的渗透脆性升高，膜脂流动性下降，膜丙二醛（ＭＤＡ）含量明显升高，但红细胞溶血度未增加，红细胞膜ＳＯＤ。t was studied that the influence of 2450MHz microwave radiation on molecular level of vitro human erythorcyte membrances. The human erythorcytes were exposed a lowpower density of either 5, and 10mW/cm2 for 30 minutes respectively. The results showed that 10mW/cm2 microwave exposure enhanced the fragility of human erythorcyte membrance, reduced the fluidity of membrance lipid and increased lipid hydroperoxide of blood membrance. But microwave fields did not result in the activity of Superoxide Dismutase inside the erythroeyte and AchE on cell membrance. And the persentage contents of the components of membrance proteins did not vary either.
