title: Enhancement of carrageenin foot oedema by 1,10 -phenanthroline and evidence for the bradykinin as endogenous mediator.
abstract: Carrageenin oedema in enhanced by the simultaneous injection in the rat paw of 1,10-phenanthroline, a kininase inhibitor. The analysis of the time-course of this enhancement showed that the maximal effect was observed about 3 hours after the injection. This enhancement was also present when the oedema-producing agent was cellulose sulphate, a kinin-releasing compound. On the contrary, oedema induced by eggwhite as well as by dextran, which are mainly mediated by histamine and 5-hydroxytryptamine, were unaffected by 1,10-phenanthroline. These results further support the role of kinins in the pathogenesis of carrageenin oedema.
