Abstract
Subject headings
Close
- The intratracheal (i.t.) instillation of Sephadex beads into rat induced inflammation and a 30-fold increase in the endothelin-1-like immunoreactivity (ET-1-LI) of broncho-alveolar lavage fluid. The levels were highest 24 h after the instillation and had declined significantly after 48 h. At a dose of 1 mg kg-1 i.t., the glucocorticosteroid budesonide almost abolished this response. Phosphoramidon, which inhibits neutral endopeptidase, an enzyme reported to degrade ET-1 and also to inhibit the endothelin-converting enzyme, potentiated the Sephadex-induced rise in ET-1-LI. Chymostatin and heparin, which are reported to reduce the formation of ET-1, did not affect the increase in ET-1-LI. The present model represents a very reactive system for analyzing the changes in ET-1 levels during inflammation.
