感冒是诱发“慢性气管炎”的主要疾病。对感冒还没有找到很有效的药物,老年体弱者或婴儿等常因感冒高烧危及生命。市场上的很多感冒药物,多数属于治标方面。经长期研究找到的一些药物如吗啉胍、金刚胺之类,有的疗效不明显,有的可能引起病毒抗药性。多年来,在寻找抗感冒药物过程中,曾遇到两大难题。第一是感冒病原体很多,如流感和副流感病毒、鼻病毒、腺病毒、冠状病毒、微小核糖核酸病毒、埃可病毒等等,都能引起感冒。仅鼻病毒一种,就有100个以上型别。一种药物很难对付这么多的病原体。第二是感冒病毒易于变异,即使找到有效药物,使用后不久,即因 Cold is the main cause of “chronic bronchitis”.
