Zusammenfassung:OBJECTIVE: To investigate the effects of angiotensin II (AngII) and its receptors on monolayer permeability of pulmonary microvascular endothelial cells in rat
METHODS: The following examinations were done on cultured rat pulmonary microvascular endothelial cells (RPMVECs). 1. Micro-filter was used to assay the variations of lipopolysaccharide (LPS)-induced increased RPMVECs monolayer permeability coefficient (Kf) in different periods. 2. Effect of angiotensin II on LPS-induced permeability injury to the endothelium, and preventive effects of angiotensin II type 1 receptor antagonist (Sar1, Ile8)-Ang II
RESULTS: LPS increased RPMVECs monolayer permeability compared with normal control, and AngII exacerbated LPS-induced RPMVECs monolayer permeability significantly. This synergistic effect was significantly prevented by the addition of (Sar1, Ile8 )-Ang II
CONCLUSION: AngII and LPS have synergistic injurious effects to the pulmonary microvascular endothelium in rat, and AngII exacerbates increase in LPS-induced RPMVECs monolayer permeability. This synergistic effect is significantly prevented by the addition of (Sar1, Ile8)-Ang II
