近年来,环境温度与一些职业性危害对人体的联合作用引起了国内外学者的重视。高温作业中CO是最为常见的一种有害气体。本文研究了高温对CO毒性的影响与高温和CO的相互联合作用。 实验系采用雄性成年小白鼠140只,体重18～24克,在可控制温度的实验室内用体积为55升的染毒柜进行CO急性静式吸入毒性试验。按温度分为25℃和36℃两组,每组又分六个不同的CO浓度组和一个温度对照组。实验时,先将染毒柜放入实验室内,待染毒柜内温度达到实验所要求的温度时将动物放入,关闭紧密后用注射器注入一定量浓度的
In recent years, the combined effect of ambient temperature and some occupational hazards on the human body has attracted the attention of scholars at home and abroad. CO is the most common type of harmful gas in high temperature operation. In this paper, the effect of high temperature on CO toxicity and the interaction between high temperature and CO were studied. 140 male adult mice weighing 18-24 g were used in the experiment, and CO acute static inhalation toxicity test was performed in a controlled temperature lab with a volume of 55 liters. According to the temperature is divided into two groups of 25 ℃ and 36 ℃, each group is divided into six different CO concentration group and a temperature control group. Experiment, the first exposure to the cabinet into the laboratory, to be poisoned when the temperature inside the cabinet reaches the temperature required for the experiment when the animals into the close after the injection of a certain amount of concentration with a syringe
