Mu opioid receptor-dependent analgesic effect of lithium chloride on neuropathic mice. (a) Effect of naloxone (0.1 mg/kg, s.c.) on lithium-induced analgesia (100 mg/kg, i.p.; n = 6 per group; two-way ANOVA test with a Bonferroni correction; $p < 0.01). (b) Effect of lithium chloride on MOR null neuropathic mice (n = 6 per group, ANOVA test; n = 6. ns: non-significant). Values are means ± SEM. Pretesting group corresponds to mechanical threshold before lithium and/or naloxone injections. The 4-h group corresponds to mechanical threshold observed 4 h after lithium and/or naloxone injections. MOR: mu opioid receptor.
