结节病的临床表现与组织学改变类似结核病,因此人们怀疑其发病机制中分支杆菌可能起重要作用,但在结节病组织中,用常规培养技术未能检出分支杆菌,所以采用液相杂交法探讨其中是否存在分支杆菌rRNA。 The clinical manifestations of sarcoidosis and histological changes similar to tuberculosis, it is suspected that the pathogenesis of mycobacteria may play an important role, but in sarcoidosis, the conventional culture technology failed to detect mycobacteria, so the use of liquid Hybridization method to explore whether there is mycobacterial rRNA.
