Abstract

House dust mites produce potent allergens that exacerbate asthma in sensitized patients, whom are recommended to practice allergen avoidance within their home environment. We tested the effect of activated charcoal impregnated fibers on house dust mite survival. One hundred live adult house dust mites (Dermatophagoides pteronyssinus) were added to eight culture dishes preequilibrated at room temperature (n = 4) and 70% humidity (n = 4) containing house dust mite food and active charcoal fibers. At 10 minute intervals, live and dead house dust mites were counted. All house dust mites instantly attached to the activated charcoal fibers and started to shrink almost immediately. There were no live house dust mites present as early as 40 minutes in some dishes while after 190 minutes all house dust mites were dead. In conclusion, activated charcoal fibers, if incorporated into bedding items, have the potential to control house dust mites in the indoor environment.

活性炭纤维对室内尘螨生存影响的初步研究。

室内尘螨产生强效过敏原，加重致敏患者的哮喘，建议患者在家庭环境中避免过敏原。我们测试了活性炭浸渍纤维对屋尘螨存活率的影响。在室温(n = 4)和70%湿度(n = 4)条件下，将100只室内尘螨(Dermatophagoides pteronyssinus)活螨放入8个预先平衡的培养皿中，培养皿中含有室内尘螨食物和活性炭纤维。每隔10分钟，统计活尘螨和死尘螨。所有的室内尘螨都立即附着在活性炭纤维上，并几乎立即开始收缩。在一些培养皿中，早在40分钟就没有活的尘螨出现，而在190分钟后，所有的尘螨都死亡了。综上所述，活性炭纤维如果加入到床上用品中，有可能控制室内环境中的室内尘螨。
