大气污染危害的早期表现之一是机体免疫反应下降。测定鼻粘膜细菌培养率(MOCOH)较简单易行,但未普及,且评价标准,以及它与某些环境因素的关系报告不多。基于此,进行了本研究。作者调查了幼儿园的120名6岁儿童。按配对-对照分组。对照区远离工业企业,实验区内有合成香料厂,企业排入大气数十种低毒、有特殊臭味的化合物(醇、醚、醛)。研究了一年,分四季进行。以普通菌丛、溶血性菌丛MOCOH评价了儿童机体非特异免疫反应。用无菌棉拭子涂抹儿童的下鼻道,然后将棉拭子放入无菌试管中,一小时内接种于5%血琼脂培养基上。将
One of the early manifestations of the hazards of air pollution is a reduction in the body’s immune response. Determination of nasal mucosal culture rate (MOCOH) is relatively simple, but not universal, and evaluation criteria, and its relationship with some environmental factors reported little. Based on this, we conducted this study. The author investigated 120 6-year-olds in kindergarten. Paired - Control grouping. The control area is far away from the industrial enterprises. There are synthetic perfumery factories in the experimental area, and dozens of compounds (alcohols, ethers and aldehydes) that are discharged into the atmosphere and have low toxicity and special odor are discharged into the area. Studied for one year in four seasons. To ordinary flora, hemolytic bacteria MOCOH evaluation of children’s non-specific immune response. The child’s lower nasal passages were smeared with a sterile cotton swab. The cotton swabs were then placed in sterile test tubes and seeded on 5% blood agar medium within one hour. will
