title: The kinin antagonist hoe 140 reduces acute paw oedema in rats caused by carrageenan, bradykinin and kaolin.
abstract: The present study aimed to evaluate the effect of Hoe 140, a BK receptor B(2) antagonist, on acute oedema induced by carrageenan, BK and kaolin in male Wistar Kyoto rats. Hoe 140 (0.2 mg/kg and 20 mg/kg) given ip caused significant (p<0.05 and p<0.01) inhibition of carrageenan and BK-induced paw oedema. This suggests that BK is the prime inflammatory mediator of carrageenan oedema, and that it is also a specific blocker of oedema caused by BK. Furthermore, Hoe 140 was found to be less effective in reducing kaolin-induced oedema in rats. This might reflect that BK is not a prime inflammatory mediator of kaolin-induced oedema. The possible significance of these findings is discussed.
