摘要
一氧化氮 (NO)是在 1 976年发现的一种新型小分子物质 ,其半衰期短 ,化学性质活泼 ,广泛存在于生物体内 ,参与血管、神经系统和免疫功能等许多重要的生物调节作用。越来越多的研究表明 ,创伤愈合中细胞增殖期间的巨噬细胞、纤维母细胞、角化细胞等都存在NO的合成并影响着伤口的愈合。相反在NO合成受到抑制的伤口愈合中则存在伤口愈合延迟的现象 ,过度纤维化中减少NO的合成则可以预防瘢痕的形成。NO在创伤伤口愈合中的作用已逐渐受到了人们的重视。
NO was found in 1976 as one new small molecule,which exists in body widely and participate in many important bio modulation activity of blood,nerve and immune system.?It has a short half time,and is chemically very active.?More study showed that NO is synthesized in macrophages,fibroblasts and keratinocytes during healing of trauma.?On the contrary,the healing was retarded when the NO synthesis was inhabited.?In excess fibrosis,the decrease of NO synthesis could prevent the scar formation.?Function of NO in trauma healing has been recognized gradually by the people.
