Figure 2

(a) The scores of crossings of rats (n = 10) during open-field tests. Ketamine administered at the dose of 10 mg/kg did not affect the scores of crossings, and pretreatment with 5 mg/kg tramadol did not affect any changes of scores of crossings (P > 0.05). (b) The scores of rearings of rats (n = 10) during open-field tests. Ketamine administered at the dose of 10 mg/kg did not affect the scores of rearings, and pretreatment with 5 mg/kg tramadol did not affect any changes of scores of rearings (P > 0.05).
