in both nuclei, this response was antagonised by the selective alpha(2a)-antagonist brl 44408 (1 microm: p<0.001 vs. dexmedetomidine) but not by the selective alpha(2b/c)-adrenoceptor antagonist arc 239 (500 nm), the selective 5-ht(1a) antagonist way 100635 (100 nm) or the alpha(1)-selective antagonist prazosin (1 microm), suggesting that the effect of dexmedetomidine is wholly attributable to alpha(2a)-receptor activation. |

since the effect of dexmedetomidine was not antagonised by prazosin, we suggest that its effect was mediated directly, possibly through alpha(2a) receptors located on 5-ht cell elements, and not transduced indirectly through alpha(1)-adrenoceptor activation, as previously suggested by others. |

these results suggest that neither alpha(2a), alpha(2b) nor alpha(2c) ar is required for the development of neuropathic pain after peripheral nerve injury, however, the spinal alpha(2a) ar is essential for the antinociceptive effects of dexmedetomidine. |

the alpha(2)-adrenoceptor agonist, dexmedetomidine inhibited the stimulation-evoked release of na from kidney slices in a concentration-dependent manner, whereas alpha(2)-adrenoceptor antagonist ch-38083 (7,8-methyenedioxy-14-alpha-hydroxyalloberbane hcl), an alpha(2)-adrenoceptor antagonists, enhanced it. |
