有实验认为川芎嗪是一种钙拮抗剂,我们比较了川芎嗪和已知的钙拮抗剂异搏定对NE和高浓度的Kcl所引起的动脉条收缩反应的影响。试进一步分析川芎嗪对血管平滑肌的作用原理。 实验应用微量生物测定法。将Wistar大鼠胸主动脉剪取成螺旋条置浴槽中,以饱含氧
It has been experimentally considered that tetramethylpyrazine is a calcium antagonist. We compared the effects of ligustrazine and the known calcium antagonist verapamil on arterial contractions caused by NE and high concentrations of KCl. Try to further analyze the role of ligustrazine on vascular smooth muscle. Experimental application of micro-bioassay. The Wistar rat thoracic aorta was cut into a spiral strip bath to full oxygen
