ABSTRACT
The research work on air purification and disinfection in air defence fortifications was carried out. The air purification method could reduce bacteria, fungi, CO2 concentration and odor in the air. It might increase the clean degree of the air from Degree HI to Degree Ⅱ in the operation room. Efficiency of ZSH/W type ultraviolet lamp for air disinfection was better than that of other ultraviolet lamp. The ozone produced was also less. Its bactericidal rate was 71.7%-82.7%. When Type 88 disinfectant was used for air disinfection in wards. operation room, X-ray room and office, its bactericidal rate was 99%, and fungicidal rate was 86%. All of these methods were very effective for indoor air purification and idsinfection.
ABSTRACT
The research work on recommended value for hygienic standard of airborne bacteria was made for formulating the hygienic standard of airborne bacteria in air defence fortifications of our country. Examination, classification, and kinetic observation for airborne bacteria and fungi were made in different air defence fortifications in 4 seasons of the year. 2 kind of sampling methods were compared as well. The fundamental situation of airborne microorganism and micro-climate was got in different air defence fortifications installed ventilator. The recommended value on hygienic standard of airborne bacteria in air defence fortifications was proposed according to the result investigated, sanitary demand, national and international standard, and situation of our country.
ABSTRACT
The composite was made according to the different mechanism for treating silicosis with Qianghansu (Plydroxypiperaquine and Tetrandrine).It was used for treating the experimental silicosis of Wistar rat.In comparison with the single drug group, the content of collagen in the lung of the rat in the composite group was less (P
