Lower level of memantine (5 and 25 mg/kg) could antagonize the dichlorvos-evoked down-regulation of [(3) H] MK-801 binding to NMDA receptor in rat brain [Bmax value: (0.55 +/- 0.07) and (0.64 +/- 0.07) pmol/mg pro; Kd value: (38.68 +/- 4.54) and (32.58 +/- 3.90) nmol/L respectively] while higher dose of memantine (45 mg/kg), the Bmax (0.45 +/- 0.06) pmol/mg pro and Kd (22.88 +/- 4.42) nmol/L of NMDA receptor were significantly decreased (P < 0.01).

Dichlorvos evoked down-regulation of the affinity and density of [(3) H] MK-801 binding to NMDA receptor in the brain of rats receiving dichlorvos (15 and 25 mg/kg bw, i.p.).

Diisopropylfluorophosphate (DFP), dichlorvos, cyanophos, mipafox, and o-ethyl o-4-nitrophenyl phenylphosphonothioate are relatively potent inhibitors of [3H] CPP binding to synaptic membranes.

The data indicate that both muscarinic ACh and NMDA receptor-mediated mechanisms contribute to the acute toxicity of AChE inhibitors, and NMDA receptors seem critical to OP-induced seizures.
In the present study, the effects of dizocilpine (MK-801, 1 mg/kg) or 3-((RS)-2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid (CPP, 10 mg/kg), alone or combined with muscarinic antagonist atropine (1.8 mg/kg), on convulsant and lethal properties of an OP pesticide dichlorvos or a carbamate drug physostigmine, were studied in mice.

With respect to the mechanism underlying anticholinesterase-induced neurotoxicity, muscarinic and nicotinic, as well as NMDA receptors, seem to play major roles.
Mice were administered anticholinesterase pesticides dichlorvos (DDVP) or methomyl (MET).
