【摘要】：为探讨医用空气过滤装置对粉尘螨杀灭效果及降低空气中尘螨过敏原含量的影响,挑取粉尘螨成虫放置在空气过滤装置中,按不同时间段(0,12,24,48,72,96 h)分组,每组200只粉尘螨,处理后采取样本进行杀螨率检测及扫描电镜观察;采用抗原雾化法检测,收集空气过滤装置处理的1 h样品,并通过双抗体夹心法检测样品中抗原含量.结果表明:空气净化装置处理后尘螨死亡率随着作用时间的延长而逐渐升高,在72 h和96 h,尘螨死亡率分别达到60.5%和92.5%;处理后的死螨严重脱水,虫体形态高度皱缩.医用空气过滤装置对空气中粉尘螨主要抗原Der f 1和Der f 2具有显著降低作用.
[Abstract]:In order to study the effect of medical air filter device on killing dust mite and reducing the content of dust mite allergen in the air, adult dust mites were selected and placed in air filter device. They were divided into two groups of 200 dust mites in different time periods.After treatment, the mite killing rate and scanning electron microscope were observed, and the antigen content in the sample was detected by the method of antigen atomization, and the sample treated by air filter device was collected for 1 hour, and the antigen content in the sample was detected by double antibody sandwich method.The results showed that the mortality rate of dust mites increased with the prolongation of the action time, and reached 60.5% and 92.5% at 72 h and 96 h, respectively.The medical air filter can significantly reduce the main antigens Der f 1 and Der f 2 in the air.
