#008080">与对照组比较（t检验）P<0.012.4 脑中单胺类神经递质：由表2可见，辐射强度为1实验组脑组织中单胺类神经递质NE含量明显高于对照组（p<0.01），其余各项指标(5-HT、5-HIAA、DA)与对照组比较无显着性差别。 有研究发现，915MHZ照射小鼠使其腹腔温度升高3.6-4℃，本研究表明，小鼠在功率密度为1mW/cm2的900MHZ的电磁辐射暴露下，全血中脂质过氧化物增加，但暴露的功率密度增加（2mW/cm2、5mW/cm2）时，实验组与对照组未见明显异常。在强度为0.05-0.5 mW/cm2时，血红细胞、血红蛋白含量升高，而1 mW/cm2时未见改变，作者认为这是机体的代偿反应所致。并经过一系列急性、亚急性和慢性免疫实验证实，短期微波辐射，对机体免疫功能有刺激作用，长期微波作用，其免疫效应可以转向抑制，呈现代偿-适应-代偿不全的动力学过程。 移动电话手机对神经行为影响调查随着无线通讯事业的迅速发展，移动电话手机电磁辐射对机体的健康影响也越来越多的引起了人们的重视。1.1 研究对象选择有或无移动电话手机的公司职员共144人为研究对象，其中观察组为移动电话手机用户81人，对照组非手机用户为63人。 影响因素分析由表1可见，观察组与对照组在吸烟、年人均收入和睡眠规律性方面有显着性差异，在分析健康影响时应进行多因素分析。其他指标如年龄、性别、职业、文化程度及环境因素暴露情况等两组之间无显着性差异。 表1 观察组与对照组一般情况 * p<0.05 ** p<0.01 （1）几何均值 两组人群神经行为功能操作测试结果比较经协方差分析，观察组和对照组简单反应时间测试，两组人群平均反应时间分别为446.5和425.0 ms。观察组较对照组平均反应时间延长（p<0.01）。其他操作测试指标两组之间无显着性差异（见表2）。表2 观察组和对照组神经行为操作测试结果协方差分析（x±s）<1> <table class="MsoNormalTable" style="BORDER-RIGHT: medium none; BORDER-TOP: medium none; MARGIN-LEFT: 6.75pt; BORDER-LEFT: medium none; MARGIN-RIGHT: 6.75pt; BORDER-BOTTOM: medium none; BORDER-COLLAPSE: collapse" cellSpacing="0" cellPadding="0" align="left" border="1"><tbody><tr style="HEIGHT: 1cm"><td style="BORDER-RIGHT: windowtext 1pt solid; PADDING-RIGHT: 5.4pt; BORDER-TOP: windowtext 1pt solid; PADDING-LEFT: 5.4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: windowtext 1pt solid; WIDTH: 62.25pt; PADDING-TOP: 0cm; BORDER-BOTTOM: windowtext 1pt solid; HEIGHT: 1cm" vAlign="top" width="83">组别</td><td style="BORDER-RIGHT: windowtext 1pt solid; PADDING-RIGHT: 5.4pt; BORDER-TOP: windowtext 1pt solid; PADDING-LEFT: 5.4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: medium none; WIDTH: 62.3pt; PADDING-TOP: 0cm; BORDER-BOTTOM: windowtext 1pt solid; HEIGHT: 1cm" vAlign="top" width="83">平均年龄（x±s）</td><td style="BORDER-RIGHT: windowtext 1pt solid; PADDING-RIGHT: 5.4pt; BORDER-TOP: windowtext 1pt solid; PADDING-LEFT: 5.4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: medium none; WIDTH: 62.3pt; PADDING-TOP: 0cm; BORDER-BOTTOM: windowtext 1pt solid; HEIGHT: 1cm" vAlign="top" width="83">男/女</td><td style="BORDER-RIGHT: windowtext 1pt solid; PADDING-RIGHT: 5.4pt; BORDER-TOP: windowtext 1pt solid; PADDING-LEFT: 5.4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: medium none; WIDTH: 62.3pt; PADDING-TOP: 0cm; BORDER-BOTTOM: windowtext 1pt solid; HEIGHT: 1cm" vAlign="top" width="83">吸烟率*（%）</td><td style="BORDER-RIGHT: windowtext 1pt solid; PADDING-RIGHT: 5.4pt; BORDER-TOP: windowtext 1pt solid; PADDING-LEFT: 5.4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: medium none; WIDTH: 62.3pt; PADDING-TOP: 0cm; BORDER-BOTTOM: windowtext 1pt solid; HEIGHT: 1cm" vAlign="top" width="83">饮酒率（%）</td><td style="BORDER-RIGHT: windowtext 1pt solid; PADDING-RIGHT: 5.4pt; BORDER-TOP: windowtext 1pt solid; PADDING-LEFT: 5.4pt; PADDING-BOTTOM: 0cm; BORDER-LEFT: medium none; WIDTH: 62.3pt; PADDING-TOP: 0cm; BORDER-BOTTOM: windowtext 1pt solid; HEIGHT: 1cm" vAlign="top" width="83"><p class="MsoNormal" style="TEXT-ALIGN: left"
