川芎嗪、冰片对纤毛持续运动时问的影响

目的：考察“纤毛持续运动时间体外及体内法”在川芎嗪、冰片上的运用。方法：（1）体外法——取离体蛙上腭黏膜，滴加药液后于40倍光学显微镜下观察黏膜纤毛持续运动时间。再洗净黏膜，观察纤毛摆动是否恢复，并记录从恢复摆动开始至摆动再次停止所持续的时间。（2）体内法——于青蛙上腭黏膜滴加药液或生理盐水，接触30min后洗净，分离上腭黏膜于40倍光学显微镜下观察黏膜纤毛持续运动时间。结果：川芎嗪离体法及在体法的纤毛持续运动时间相对百分率分别为9．8％、87．3％；冰片离体法及在体法的纤毛持续运动时间相对百分率分别为9．3％、89．5％。结论：纤毛持续运动时间体外及体内法均可以作为中药鼻黏膜毒性筛选方法之一，并各有利弊。川芎嗪、冰片对体外纤毛持续运动时间有显著的毒性影响。

Effect of Ligustrazine, Synthetic Borneol on Lasting Time of Ciliary Movement

OBJECTIVE: To study the using of the method in vitro and in vivo of lasting time of ciliary movement in ligustrazine, synthetic borneol. METHODS: (1) Method in vitro-The lasting time of ciliary movement was observed with forty-fold optical microscope after dropping liquid medicine on exteacorporeal frog palate mucosa. Then mucosa was cleared. It was observed whether the ciliary movement was recovered and the lasting time was recorded from recovering to stopping once again. (2) Method in vivo-Liquid medicine or normal saline was dropped on frog palate mucosa by contacting thirty minutes. Then mucosa was cleared. The lasting time of ciliary movement was observed with forty-fold optical microscope by separating palate mucosa. RESULTS: Relatively percentage of lasting time of ciliary movement of ligustrazine in vitro and in vivo was 9.8%, 87.3%; The relatively percentage of synthetic borneol in vitro and in vivo was 9.3%, 89.5%. CONCLUSION: The method in vitro and in vivo of lasting time of ciliary movement can be the one of the selecting ways of Chinese drug's toxicity of nasal mucosa, and it have virtues and defects respectively. Ligustrazine, synthetic borneol have significantly toxical effect on exteacorporeal lasting time of ciliary movement.
