目前已从香烟中分离出多种有害化合物并对其引起某些疾病的发病机理进行了许多研究,而有关吸烟对生物膜是否存在损伤作用尚未见报道。本文以生物膜的一顷重要指标——谷胱苷肽过氧化物酶活性(GSH—PX)试图评价吸烟对生物膜的影响。 So far, many harmful compounds have been isolated from cigarettes and many researches have been done on the pathogenesis of certain diseases. However, there is no report about the effect of smoking on the biofilm damage. In this paper, an important indicator of biofilm - glutathione peroxidase activity (GSH-PX) trying to evaluate the impact of smoking on the biofilm.
