饱和潜水作业时苯可作为舱室环境气的污染物之一。在高气压条件下长时间连续吸入低浓度苯的危害性问题尚未引起人们重视。我们拟通过本实验获得对高气压下苯毒理作用的初步认识。材料与方法一、实验动物选用SD纯种雄大鼠24只,体重210～290g,随机分成3组:高压苯染毒纠、高压对照组和常压对照组各8只。各组分別集中笼养。二、模拟饱和潜水条件采用双舱四门式加压舱,主、副舱室容积分别为8和4m~3。模拟30m水深、氮氧饱和潜水15天,
When saturated diving operations, benzene can be used as one of the pollutants in the cabin environment. Under the conditions of high pressure continuously inhaled low concentrations of benzene for a long time harmful issues have not attracted much attention. We intend to pass this experiment to obtain a preliminary understanding of the toxicological effects of benzene under high pressure. MATERIALS AND METHODS First, 24 SD purebred male rats weighing 210-290 g were randomly selected and divided into three groups randomly: high-pressure benzene group, high-pressure control group and normal-pressure control group. Each group were concentrated in cage. Second, the simulation of saturated diving conditions Double-cabin four-door pressurized tank, the main and auxiliary compartment volume were 8 and 4m ~ 3. 30m water depth simulation, nitrogen and oxygen saturation diving for 15 days,
