title: The role of kinin B1 in the plasma extravasation of carrageenin-induced pleurisy.
abstract: The role of des-Arg9-bradykinin (des-Arg9-BK) and kinin B1 receptor in the plasma extravasation of rat carrageenin-induced pleurisy was investigated employing B1 receptor agonist and antagonists and kininogen-deficient rats. Expression of the B1 receptor mRNA in pleura was induced from 3 to 5 h after the injection of carrageenin into the pleural cavity of Sprague-Dawley rats. Exogenous injection of des-Arg9-BK into the pleural cavity provoked a significant increase in plasma extravasation in 5 h carrageenin-induced pleurisy, but not in 20 min kaolin-induced pleurisy. The level of immunoreactive des-Arg9-BK in the exudate of 5 h carrageenin-induced pleurisy was higher than that of bradykinin (BK). Administration of the B1 receptor antagonists, des-Arg9-[Leu8]-BK or des-Arg9-D-Arg-[Hyp3, Thi5, D-Tic7,Oic8]-BK significantly reduced the exudation rate. However, intrapleural administration of des-Arg9-BK to plasma kininogen-deficient. Brown Norway-Katholiek rats did not result in a further increase in the plasma extravasation. In conclusion, endogenously generated des-Arg9-BK could contribute to the plasma extravasation in carrageenin-induced pleurisy via mediation of the inducible B1 receptor.
