Effect of the pretreatment with Ouabain (OUA, 0.56 mg/kg) administered intraperitoneally on acetic acid-induced writhing and hot plate test in mice. Each bar represents the mean of six or ten animals. Morphine (MOR, 10 mg/kg) administered intraperitoneally was used for analgesia. Naloxone (NLX, 5 mg/kg), an opioid antagonist, was used to test the involvement of opioid receptors. Asterisks denote the significance level compared with control values; # compared with the Ouabain group and + compared with the morphine group. Data were expressed as mean ± S.E.M. and analyzed by software Graphpad Prism using (ANOVA) followed Dunnett's test. *P < .05; **P < .01, and ***P < .001.
