Abstract
Background & Objective: Herbal medicine has an old history with a broad application all over the world. Many researches have focused on the curative as well as antinociceptive effects of herbal extracts. In the previous study the analgesic effect of Chamomile extract containing 2 mg/kg essence in Rats which revealed a significant analgesic effect were studied. In this study it is planned to compare the analgesic effect of chamomile extract and Morphine (as a standard analgesic) in mice. Methods: This experimental study was carried out in Shahid Sadughi Medical School on 48 Syrian mice (25-30 grams) which were randomly divided into 8 groups. In this study the analgesic effect of intraperitoneal administration of Chamomile extract containing 2 mg/kg essence and different doses of Morphine (0.5, 1.0 and 2.0 mg/kg) were assessed by using Formalin Test (for chronic pain during 1 hr. post Formalin injection) and Tail Flick Test (for acute pain during 2 hr. post drug administration in 15 min. time intervals). Results: The results of this study showed that 2nd phase of Formalin Test had more analgesic effect than that of 0.5 mg/kg morphine. In the case of Tail Flick Test its analgesic effect was prominent 30-90 min. after drug administration which was identical to the analgesic effect of 1.0 and 0.5 mg/kg Morphine Sulfate (P > 0.05). Conclusion: Data from this study confirms the analgesic effect of chamomile essence which was indicated in our previous study and that this analgesic effect is comparable with 1 mg/kg of morphine sulfate in both the Formalin TEST & Tail Flick TEST. Chamomile as an analgesic should be studied more in different studies.

Abstract
Background & objectives: The pathophysiology of depression is very complex. Rosa canina L fruit contains various antioxidant compounds. The aim of this study was to investigate the anti-depressant and anti-anxiety effects of the aqueous- alcoholic extract of the Rosa canina L fruit in the behavioral tests including forced swimming, tail suspension, maze, and sucrose preference tests, as well as biochemical tests such as antioxidant capacity and malondialdehyde levels. Rosa canina L with high amounts of vitamin C, has anti-depressant and anxiety effects.
Methods: In this experimental study, 60 Syrian male mice were divided into 5 groups of 12, including the control group, the bisphenol A group, and three groups treated with oral bisphenol A at a dose of 125 mg/kg per day and the aqueous- alcoholic extract of the Rosa canina L fruit at doses of 100, 200, 400 mg/kg/day was administered from day 50 to 120 after birth. The data were analyzed using SPSS statistical software and the One Way ANOVA test. The level of significance was set at p<0.05.
Results: The findings showed that bisphenol A significantly increased the duration of immobility in the forced swimming and tail suspension test. The extract at the level of 400 mg/kg decreased the duration of immobility in both tests. Bisphenol A significantly reduced the antioxidant capacity of serum and brain. The extract at the level of 400 mg/kg significantly increased the antioxidant capacity of both the brain and serum.
Conclusion: The findings of this research showed that the fruit of the Rosa canina L has antioxidant effects, and with a significant decrease in antioxidant capacity and immobility in Syrian mice treated with the extract, therefore it has anti-depressant and anxiety effects.
