[Antidepressant effect of acute administration with Jianyate Hao (JYTH) and its possible mechanism].
OBJECTIVE
Jianyate Hao (JYTH) , a traditional Chinese medicine formula, which has been used effectively to treat depression in the past ten years. The purpose of this study was to explore the antidepressant effect of acute administration with JYTH and its possible mechanism.


METHODS
the animals behavioral despair models of depression, the tail suspension and forced swimming tests, were used to explore the antidepressant effects of JYTH. In addition, the locomotor activity test was used to detect the change of locomotor activity. The monoamine oxidase activity in the mouse brain was also determined by using fluorospectrophotometry.


RESULTS
JYTH (17.5, 35, 70 g x kg(-1), ig) could decrease the duration of immobility in both tail suspension and forced swimming tests, and the effect of JYTH (35 g x kg(-1) ig) was resembling imipramine (10 mg x kg(-1), ip) in relieving depression. And the effective doses (17.5, 35, 70 g x kg(-1), ig) did not alter locomotion activity. Moreover, JYTH (35 g x kg(-1), ig) was found to inhibit monoamine oxidase activity in the mouse brain.


CONCLUSIONS
These findings suggest that JYTH exerts antidepressant effect in animals behavioral despair tests and the underlying mechamism may involve the inhibition monoamine oxidase activity in the mouse brain.
