选择热板法、扭体法、痛经模型、急性应激血淤血液流变性等方法，比较川芎配方颗粒及饮片、酒川芎配方颗粒及饮片的主要药理作用。结果川芎配方颗粒与川芎饮片标准汤剂、酒川芎配方颗粒与酒川芎饮片标准汤剂均能延长小鼠热板痛闭值，均能延长醋酸所致扭体反应的小鼠扭体潜伏期并减少扭体次数，均能延长小鼠痛经模型中催产素所致扭体反应的潜伏期并减少扭体次数，均具有改善急性应激血淤大鼠血液流变的作用。

Chintin with chintin film processing is not complicated, first of all the industrial processing of accumulation of crab and shrimp when chintin inmnersion hydrochloride, and a strong base to calcium and protein deposits, you can be assured of semi-finished chintin powder; and then add the acetic acid powder soluble in chintin erjia polyamlnes vlproic bisprone nitrogen and licl mixture, mixed solution evenly onto a glass plate, and lixiviating propylalcohol solution would reflect on the glass panes for the transparent on the film.

用甲壳质加工甲壳薄膜的工艺并不复杂，首先将工业加工蟹虾时积聚的甲壳质用盐酸浸泡，再用强碱使钙和蛋白质沉淀，就可得到半成品的甲壳粉末；然后将甲壳粉末溶于醋酸二甲胺、氮戊环酮和氯化锂混合液中，再将混合溶液均匀地洒在玻璃板上，并在异丙醇溶液中浸一下，玻璃板上便形成了透明的甲壳薄膜。
