211.154.163.124
Methods:After preparation of the rat thoracic aorta rings, the tension of the rings was measured by biological signal analytical system.
方法：制备离体大鼠胸主动脉环，经生物信号采集与分析系统测定血管环的张力变化。
GD at different concentrations did not show significantly inhibitory effect on PE-induced tension of endothelium-denuded thoracic aorta rings in HKR group (P>0.05).
在去内皮的主动脉环上，不同浓度GD预孵育后对PE收缩张力无显著作用（P>0.05）。
