Embodiment Construction
[0025] The radon lung injury protective agent developed by the present invention uses method and experimental result as follows:
[0026] 1. Animal grouping and radon exposure:
[0027] 18 clean-grade male SD rats, weighing about (150±20) g. They were randomly divided into control group, radon exposure group and radon lung injury protection agent group, with 6 rats in each group. Put the rats in radon exposure group and radon lung injury protection agent group into HD-3 multifunctional ecological radon chamber, the radon concentration in the radon chamber environment is 40000Bq / m3, and the total exposure time of each rat is 1890h, that is, 120 working level month (WLM), the dose rate is 0.056WLM / h. The rats in the radon lung injury protective agent group were given 5ml (1000g / L) radon lung injury protective agent by intragastric administration once a day, and the radon exposure group were given 5ml normal saline intragastric administration once a day; 50Bq / m3 of room temper...
