Libidibia ferrea Mature Seeds Promote Antinociceptive Effect by Peripheral and Central Pathway: Possible Involvement of Opioid and Cholinergic Receptors

Figure 6

The effects of different antagonists on the antinociceptive activity of the LPLF in the acetic acid-induced contortions. Animals were pretreated with naloxone (5 mg/kg, i.p.), atropine (5 mg/kg, i.p.), or celecoxib (5 mg/kg, i.p.) 30 min prior to oral administration of the Libidibia ferrea seed oil (10 mg/kg, p.o.). The results are presented as the mean ± S.E.M ( ) of total writhings. *** compared to control group, Tukey’s multiple comparison test.
