D-Serine, a selective agonist for the strychnine-insensitive glycine allosteric site associated with the NMDA receptor-ion channel complex, was found to modulate differentially the antinociception produced by kappa and mu-opioid receptor agonists in the rat formalin test.

The bicuculline-strychnine rhythm frequency decreased during mu-opioid receptor activation or decreased bath P (C)(O (2)).

Excitatory postsynaptic currents (EPSCs) or potentials (EPSPs) were evoked electrically at the ipsilateral dorsal root entry zone after blocking inhibitory inputs with bicuculline and strychnine, and NMDA receptors with D-2-amino-5-phosphonopentanoic acid.

The Role of protein kinase C in the modulatory effect of a mu-opioid receptor agonist, [D-Ala (2),N-Me-Phe (4),Gly (5)-ol] enkephalin (DAMGO), on the glycine-gated Cl (-) current was examined in acutely dissociated rat periaqueductal gray neurons.
The glycine-gated Cl (-) current (I (Gly)) was sensitive to strychnine.

The mu-opioid receptor agonist, [D-Ala2, MePhe4, Gly-ol5]-enkephalin (DAMGO), when applied locally to the retina at concentrations between 1-30 microM significantly increased the light-evoked release of ACh.
Blockade with bicuculline and strychnine of GABAergic and glycinergic inputs to the cholinergic neurones did not affect the action of DAMGO on ACh release.

Transverse slices were made from the lumbar spinal cord of 10- to 17-day-old rats, placed in a recording chamber, and perfused with artificial cerebrospinal fluid also containing bicuculline (10 microM) and strychnine (1 microM).
Only LT-evoked field potentials were found to be reliably inhibited by the mu opioid receptor agonist [D-Ala (2), N-Me-Phe (4), Gly (5)] enkephalin-ol (DAMGO, 1 microM), although evoked potentials from both DR and LT were blocked by the AMPA/kainate glutamate receptor antagonist 6-cyano-7-nitroquinoxalene-2,3-dione.

Slices of the rat caudatoputamen were prelabeled with [3H] choline and release of [3H] acetylcholine was stimulated through either N-methyl-D-aspartate (NMDA) receptors or strychnine-sensitive glycine receptors.
Electrically evoked release of [3H] noradrenaline ([3H] NA) and its presynaptic modulation by morphine through mu-opioid receptors in neocortical slices of the rat, preloaded with [3H] NA, was nearly identical in both ethanol-naive rats and in ethanol drinking rats.

The inhibitory effects of ME were mimicked by the selective mu-opioid receptor agonist endomorphin-1 (EM, 3 microM) and were blocked by naloxone (1 microM).
The remaining mPSCs had much slower kinetics (decay time = 19.6 ms) and were GABAergic [miniature inhibitory postsynaptic currents (mIPSCs)] as they were blocked by gabazine (3 microM) but not by strychnine (3-10 microM).
