老年人的易感染性在临床上是常见的。其原因,不清楚之处还不少,特别是关于非特异性感染防御机构的实质几乎不了解。迄今为止,关于老年人的中性粒细胞机能的论述仅有10篇。根据文献报告,对于老年人的嗜中性白细胞的粘附性亢进这一结论是一致的,而其他的机能如趋化性,随机移动性,吞噬性,杀菌性,NBT还原性等,可能由于对象和测定方法的不同,其结果有正常或低下,意见尚未一致。 Elderly susceptibility is clinically common. The reason for this is not clear, and there is little known about the substance of non-specific infection defenses. To date, there are only 10 articles on the neutrophil function in the elderly. According to the literature, the conclusion is that the adhesion to neutrophils in the elderly is consistent, while other functions such as chemotaxis, random mobility, phagocytosis, bactericidal activity, NBT reducibility and the like may be due to Subjects and determination of different methods, the results were normal or low, the views have not been consistent.
