| Research Abstract |
Diabetes mellitus (DM) could enhance 5-HT-induced vasocontraction via the activation of 5-HT2A and 5-HT1B receptors of the human internal thoracic artery (ITA) and saphenous vein (SV). The enhanced vasocontractions to 5-HT in DM were mediated by the activation of Rho/Rho kinase pathways. Insulin inhibited 5-HT-induced vasocontraction in SV. These results inducate the useful pharmacological findings to prevent 5-HT-induced vasospasm when the human ITA and SV from patients with DM were used as an arterial graft.
