Abstract | BACKGROUND: Juglans regia leaves have been used in folk medicine to alleviate inflammatory diseases. This study investigates the antinociceptive, anti-Inflammatory and acute toxicity effects of Juglans regia L. leaves in mice. METHODS: 351 Male and female albino mice were divided into negative (saline), positive ( morphine or diclofenac) controls as well as test groups (n=6-8). The acute (intraperitoneally) toxicity was evaluated for 2 days. Antinociceptive activities were done using hot-plate and writhing tests. Anti-inflammatory effects were studied using xylene induced ear edema and cotton pellet tests. RESULTS: The LD50 values of J. regia aqueous and ethanolic extrats were 5.5 and 3.3 g/kg, respectively. The aqueous (2.87 and 1.64 g/kg) and ethanolic (2.044 and 1.17 g/kg) extracts showed antinociceptive activity in hot-plate test. The pretreatment of naloxone (2 mg/kg, s.c.) did not inhibit the extracts activities. The extracts exhibited antinociceptive activity in writhing test, which were not blocked by naloxone. In xylene test, both extracts showed anti-inflammatory activity in some doses. The extracts showed anti-inflammatory activity against the chronic inflammation. CONCLUSION:
