摘要
以２４５０ＭＨｚ连续微波辐照ＢＡＢＬ／Ｃ，小鼠离体淋巴细胞１５ｍｉｎ，３０ｍｉｎ，６０ｍｉｎ．结果发现０．５ｍｗ·ｃｍ－２组细胞内Ｃａ浓度明显下降，５和５０ｍＷ·ｃｍ－２组辐照３０ｍｉｎ后，细胞内Ｃａ２＋明显超载，并且表现出与质膜ｃａ２＋、Ｍｇ２＋－ＡＴＰ酶活性变化明显相关．ＤＮＡ合成结果提示，细胞内高ｃａ２＋可抑制细胞ＤＮＡ合成。
Lymphocytes in vitro of BALB/C mice were exposed to 2450MHz continuous microwave for 15min, 30 min or 60min.The results were that the concentration of intercellular Ca2+ decreased at 0.5,W·cm-2. but for more than 30min at 5 and 50mW·cm- 2,it increased significantly.It showed the concentration of intercellalar Ca2+ was related to the change of plasma membrane Ca2+ Mg2+ -ATP ase activity. The synthesis of DNA suggested that high intercellular Ca2+ inhibited the incorpration of 3H-TdR.
