Modulation of 5-HT4 receptor function in the rat isolated ileum by fluoxetine: the involvement of endogenous 5-hydroxytryptamine.

abstract：:1. We investigated the effect of KB-R7943, a Na(+)/Ca(2+) exchange inhibitor, on the aggregation response induced by adrenaline and 5-hydroxytryptamine (5-HT), alone or in combination in human and rabbit platelets in the presence or absence of ouabain. 2. KB-R7943 inhibited aggregation induced by the combination of ad...
