RESUMO
In order to meet the needs of social development for public health talents and optimize the curriculum system and teaching content of preventive medicine, the course of "Health Emergency" should be set up. It integrates the related content in many courses, and there are 20 hours for theory and 18 hours for experiment or practice. The course takes the emergency response as the cutting point focuses on the projects with high demand of the industry improves the platform and expands the content of emergency skill training through the extracurricular activities and special lectures. Combining theory with practice, this paper explores teaching reform measures that are conducive to improving students' core competence in public health.
RESUMO
Objective To study the inhalation toxicity of volatile organic compounds in mice. Methods The VOC mixture was prepared according to the monitoring data on indoors air. NIH mices were exposed to the gaseous mixture at the doses of 80.00 mg/m3,64.00 mg/m3,51.28 mg/m3,40.96 mg/m3,32.79 mg/m3 and 26.21 mg/m3 to determine the acute toxicity,and at the doses of 10.75 mg/m3,5.38 mg/m3,2.69 mg/m3 to examine the toxic effect on the weight,organ coefficient,the activity of GSH-Px and SOD and the contents of MDA in the serum. The accumulative toxicity was determined. Results The LD50 of acute inhalation toxicity was 53.74 mg/m3.After exposed to this gaseous mixture for 30 days,the body weight decreased significantly,the organ coefficient of liver and kidney changed,and the activity of GSH-Px and SOD decreased,the contents of MDA in serum increased. The accumulation coefficient was above 5. Conclusion This VOC mixture has weak accumulation toxicity in mice,but have some other toxicity.
