2250556-1	1990	The spinal antinociceptive interaction between the opiate receptor subtype agonists morphine (mu), U69593 (kappa) and [D-Pen2,5]-enkephalin (DPDPE; delta) with clonidine (alpha 2 adrenergic) was examined.	Clonidine	160-169	proenkephalin	Rattus norvegicus	129-139	
20007733-2	2010	In this study, we determined whether the spontaneous pain and increased pNR1 expression induced by NMDA injection are reduced by IT injection of either clonidine or the mu-opioid receptor agonist, [D-Ala2, NMe-Phe4, Gly-ol5]-enkephalin (DAMGO).	Clonidine	152-161	proenkephalin	Rattus norvegicus	225-235
