Analysis of opioid receptor subtypes involvement in MEMC-induced antinociception against acetic acid-induced writhing test inn mice. Control (C: 10% DMSO, p.o.), MEMC (500 mg/kg, p.o.), naloxone (NLX: 5 mg/kg, i.p.), naltrindole (NALT: 1 mg/kg, i.p.), β-funaltrexamine (β-FNA: 10 mg/kg, i.p.), nor-binaltorphimine (nor-BNI: 1 mg/kg, i.p.) and acetylsalicylic acid (ASA: 100 mg/kg, p.o.). ^***P < 0.001 when compared to the group treated only with MEMC; ^**p < 0.01 when compared to the group treated only with MEMC.
