坑道是杀伤敌人保存自己最有效的工事之一,但有关坑道密闭7天的报导材料甚少,尤其在西北高原地区有关这方面的材料更少。所以为了给坑道卫生提供可靠的依据,我科于1987年7月进行了密闭坑道7天对人体免疫影响的试验,现将结果报告如下。 对象与方法 一、对象:随机选择某部平素身体健康的男性指战员60名,年龄18～25岁,在进坑道前一天和进驻坑道第七天分别测定了CH_(50)、C_3、C_4、IgG、IgA、IgM、LTT的变化。 二、方法:①进驻坑道的指战员试验前两周及试验其间,未用过任何药物。②坑道总面积1200m~3,平均每人为20m~3,实际使用12.5m~3。进出口
Tunnels are one of the most effective work to kill enemies to save themselves, but few reports have been made on the 7-day confinement of the tunnels, especially in the Northwest Plateau. Therefore, in order to provide a reliable basis for the hygiene of tunnels, our department conducted an experiment on the impact of human body immunity for 7 days in a confined tunnel in July 1987, and the results are reported as follows. Subjects and Methods I. Object: Sixty male warfighters, aged 18-25 years, were randomly selected to take part in a healthy body. CH_ (50), C_3, C_4, IgG , IgA, IgM, LTT changes. Second, methods: ① officers and men stationed in the tunnel two weeks before the test and during the test, have not used any drugs. ② The total area of the tunnel is 1200m ~ 3, with an average of 20m ~ 3 per person and the actual use of 12.5m ~ 3. import and export
