Abstract
Background: In traditional medicine, Olive oil (Olea europaea L.) from Oleaceae family is known as a remedy for alleviating pain. This study investigates the antinociceptive effects of olive oil on male adult NMRI mice.
Materials and Methods: In this experimental study, using the acetic acid-induced writhing and formalin tests, the anticipative effects of olive oil were evaluated. Olive oil (1, 5, and 10 ml/kg bodyweight), morphine (10 mg/kg bodyweight), and indomethacin (10 mg/kg bodyweight), as standard drugs, were injected intraperitoneally. The control group did not receive any treatment. Data were analyzed using one-way ANOVA and Tukey test.
Results: Olive oil significantly decreased acetic acid-induced abdominal writhes (P<0.001). Olive oil could only decrease the induced pain in the second phase of the formalin test (P<0.001).
Conclusion: Olive oil decreases inflammatory pain (the second phase of the formalin test and acetic acid-induced writhing tests), but it has no significant effects on neurogenic pain (the first phase of the formalin test). Further studies are required to elucidate the antinociceptive effects of olive oil.

Abstract
Background: The rhizome of Iris songarica Scherenk has been prescribed as anodyne in Persian traditional medicine system. However, its effects have never been investigated experimentally. Thus, the present study was designed to evaluate the antinociceptive and anti-inflammatory effects of alcoholic extract of Iris songarica Scherenk rhizome in mice.
Material and Methods: In this experimental study, adult male balb/c mice were used. 40 animals were allocated into five equal groups (control, morphine 5mg/kg, the extracts at doses of 100, 200 and 300 mg.kg) and tested for antinociceptive evaluation via using hot-plate in 30,60 and 120 minutes after the investigations. Also, the other 36 mice were divided into six equal groups (no-inflammation control, inflammation model, dexamethasone 4 mg/kg and the extracts at doses of 100, 200 and 300 mg.kg) and evaluated for anti-inflammatory activity in xylene induced inflammation model. All the investigations were done via intraperitoneal injection. Data were analyzed using one-way ANOVA or Kruskal-Wallis tests in SPSS.
Results: Compared to the control group, the extract at the all doses could increase latency time in hot plate test at 30, 60 and 120 minutes after investigation (p<0.05).This potential was comparable to morphine in the high doses or long time. In addition, the extracts at the all doses exhibited high anti-inflammatory activity which was comparable to dexamethasone (p<0.001).
Conclusion: The results of present study clearly showed that Iris songarica Scherenk rhizome has antinociceptive and anti-inflammatory activities in mice.
