title: Selective expression of des-Arg9-BK sensitive (B1) receptors in vivo and in vitro by angiotensin converting enzyme inhibitors.
abstract: LPS (E. Coli), captopril, enalapril, teprotide and BK-infusion induced after 18 h in rabbits an increased hypotensive response to the selective B1-receptor agonist des-Arg9-BK. A similar selective increase in responsiveness and sensitivity of the in vitro aortic strip to des-Arg9-BK taken from pretreated animals was also seen. These results suggest that angiotensin converting enzyme inhibitors may elevate endogenous kinin levels which may contribute towards the inflammatory side-effects seen with this group of drugs.
