目的研究缬草素的抗焦虑作用,并分析其可能的作用机制.方法以大鼠高架十字迷宫实验和开场实验为动物模型,考察缬草素的抗焦虑活性;用酶联免疫吸附法(ELISA)测定大鼠血清皮质酮的水平.结果缬草素(10mg.kg-1)能增加大鼠在开臂内运动时间和次数百分率,并且提高大鼠在开场中央区的次数,在大鼠高架十字迷宫与开场模型上显示出抗焦虑作用;酶联免疫吸附法表明:缬草素能降低大鼠血清皮质酮水平.结论缬草素具有明显的抗焦虑作用,机制可能与调节下丘脑-垂体-肾上腺轴功能有关 |

Aim To study the anxiolytic effects of valtrate on anxiety models and investigate the related mechanisms. Methods The elevated plus-maze test(EPM) and open field were used as in vivo model, and the anxiolytic activities of valtrate were investigated. Then the corticosterone levels in the rat plasma were measured by enzyme-linked immunosorbent assay(ELISA). Result The valtrate(10 mg·kg-1,ig) exhibited the anxiolytic effect in rats by increasing the time and entry percentage into the open arms in the elevated plus maze and the number of central entries in the open filed. ELISA showed that valtrate significantly reduced the corticosterone level in the rat plasma. Conclusion The valtrate has anxiolytic activity in behavioral models that might be mediated via the function of hypothalamus-pituitary-adrenal axis(HPAA) |
