为什么一种病毒引起神经系统疾病,另一种病毒却引起肝病,而第三种病毒可导致普通感冒?有关病毒的致病机理的传统研究和分子生物学的新进展,为上述问题和其他疑难提供了答案。这些资料将为诊断、治疗和预防病毒性疾病提供新的途径。 Carson等最近证明,急性病毒性呼吸道感染患儿的鼻腔内上皮有纤毛缺损。上呼吸道未受损的纤毛具有清除分泌物、碎屑和外来颗粒的功能。正常的纤毛含有微管,构型极为整齐,周围有九对,中心有一对。Carson等检查了一些急性上呼吸道病毒感染期间的粘膜上
Why does one virus cause nervous system diseases and the other cause liver disease while the third one causes common cold? These and other problems are the traditional research on the pathogenesis of viruses and new advances in molecular biology Provided the answer. These data will provide new avenues for the diagnosis, treatment and prevention of viral diseases. Carson et al. Recently demonstrated that there is ciliary defect in the nasal epithelium of children with acute viral respiratory infections. Upper respiratory tract uninjured cilia have the function of removing secretions, debris and foreign particles. Normal cilia contain microtubules, the configuration is very neat, there are nine pairs around, the center of a pair. Carson et al examined the mucosa during some acute upper respiratory viral infections
