Latency time values are presented as mean ± standard error. mice in each group. 0 min means 30 min before drug administration and +30 min, +60 min, +120 min, and +180 min indicate 30, 60, 120, and 180 min after drug administration, respectively. ⁢, versus control (Dunnett’s -test); , versus tramadol 10 mg/kg; , versus HMPB 200 mg/kg; , versus HMPB 400 mg/kg; , versus PBMPB 200 mg/kg; , versus PBMPB 400 mg/kg (pairwise comparison by post hoc Tukey’s HSD test).
Tests of within-subjects effects conducted by repeated measure analysis of variance reveal that for the factor “time” calculated for all methods and value = 0.000 in every case. So time is highly significant at any level of significance.
