Abstract

Mycoplasma pneumoniae, M. genitalium, M. fermentans, M. hominis, M. salivarium, M. orale, Ureaplasma urealyticum and Acholeplasma laidlawii inactivated the vascular permeability-increasing activity of bradykinin when the mixture of bradykinin and mycoplasma cells was injected after incubation at 37 degrees C for 1 h. Cell components responsible for inactivation of the activity of bradykinin were found to be arginine-specific aminopeptidase and carboxypeptidase.

摘要

肺炎支原体、生殖支原体、发酵支原体、人型支原体、唾液支原体、口腔支原体、解脲脲原体和莱氏无胆甾原体在37℃孵育1小时后，将缓激肽与支原体细胞的混合物注射时，可使缓激肽的血管通透性增加活性失活。发现负责使缓激肽活性失活的细胞成分是精氨酸特异性氨肽酶和羧肽酶。
