Clonidine 0-9 death-associated protein Rattus norvegicus 55-58 1284575-6 1992 In the presence of extracellular Ca2+ the clonidine effect was not altered by addition of omega-conotoxin GVIA 0.1 mumol.L-1 or by removal of extracellular Ca2+, suggesting that the Ca2+ entry was not involved in the modulatory mechanisms of DAP-evoked [3H]NE release by activation of alpha 2-receptor. Clonidine 42-51 death-associated protein Rattus norvegicus 242-245
