Materials and Methods: In this experimental study, one hundred-fourteen male albino mice were randomly divided into normal saline or control (10ml/kg, i.p), fluoxetine (20mg/kg, i.p), imipramine (30mg/kg, i.p) and, VO extract (50, 100, 200, 400 mg/kg, i.p), respectively. The antidepressant-like activity was performed by behavioral tests as forced swimming test (FST), tail suspension test (TST), and open field test. Results: The VO extract (100 to 400 mg/kg) reduced immobility time in both FST and TST (P<0.01 and P<0.001, respectively). The extract increased swimming time (P<0.01 and P<0.001, respectively) without significant change of climbing time (P>0.05). In OFT, doses of 200mg / kg and 400mg / kg of VO caused the reduced the number of crossings from the square and on the two feet (P <0.05 and P <0.01 respectively). Conclusion: Probably, the acute doses of the Viola odorata, similar to fluoxetine, are likely to cause anti-depressant effects. }, URL = {http://journal.bums.ac.ir/article-1-2484-en.html}, eprint = {http://journal.bums.ac.ir/article-1-2484-en.pdf}, journal = {Journal of Birjand University of Medical Sciences}, doi = {}, year = {2018} }
