Modification of cardiovascular responses to histamine by dithiothreitol.

abstract：:1. It has previously been shown that the antimigraine drug sumatriptan constricts porcine carotid arteriovenous anastomoses via 5-HT1-like receptors, identical to 5-H1B/1D receptors. The recent availability of silent antagonists selective for the 5-HT1B (SB224289) and 5-HT1D (BRL15572) receptor led us to further analy...
