| Group | Number of writhes (mean ± SEM) | Reduction in writhes count (%) |
| Control (acetic acid 1%) | 59.6 ± 6.5 | 0% | Diclofenac 10 mg/kg | 29.6 ± 3.9 | 50% | Morphine 5 mg/kg | 3.2 ± 0.8 | 95% | PLE 100 mg/kg (prior 30 min) | 25.4 ± 3 | 57% | PLE 100 mg/kg (prior 3 hrs) | 31.6 ± 3 | 47% | Naloxone + PLE (prior 30 min) | 23.4 ± 2.4 | 61% |
