可能与增强5-羟色胺能系统的功能有关。

[Abstract]Objective To investigate the antidepressant effect and mechanism of the extract of mulberry leaf(EML).Meth⁃ods Male BALB/c mice were randomly assigned to receive EML(100,200and400mg/kg)or vehicle for7days or single administra⁃tion by intragastric(ig)route.The effect of EML on spontaneous activity in mice was evaluated using the open field test.The anti-de⁃pressant activity of EML was evaluated using the tail suspension test and forced swimming test.After single ig administration of EML (100,200and400mg/kg),the effects of EML on the function central monoaminergic nervous system were evaluated using the5-hydroxy-L-tryptophan(5-HTP)induced head-twitch test,yohimbine toxicity potentiation test and rerpine test in mice.Results In the behavioral despair model,the continuous administration of EML(100mg/kg)for7days significantly reduced the immobility time in the tail suspension test and forced swimming test.Compared with the vehicle group,the inhibitory rates of immobility time were 35.5%and41%(P<0.05,P<0.01)in the tail suspension test and forced swimming test,respectively.The single treatment with EML(400mg/kg)also significantly reduced the immobility time in the tail suspension and forced swimming test,and the inhibitory rates of immobility time were29.1%and35.3%,respectively(P<0.05).The results of spontaneous activity test showed that EML had
