采用小鼠断头法、亚硝酸钠(NaNO2)致死法、大鼠大脑中动脉栓塞法，通过观察断头喘息时间、亚硝酸钠致死时间、脑缺血行为评分、脑缺血面积，明确川芎嗪对脑损伤的保护作用。

Results:Biochemical indicators: the concentrations of K+, Na+ and Cl－ in the serum after the infusion are different with those before the infusion; other indicators don't have the significant difference. The mean infusion time of group A is longer than that of group B (p=0.006), while the dosis letalis of KCl doesn't have significant difference between groups (p=0.062); the concentrations of K+ in blood, Na+, Mg2+ and Cl－ in serum have the significant difference between groups; the urine volume and the concentrations of all the urine electrolyte indicators don't have the statistical significant difference between groups.

结果：生化指标：输入钾前后，家兔血清钾离子浓度升高，钠、钙及氯离子浓度降低，具有统计学显著性差异，p=0.000；全血钾及血清其他离子浓度变化，以p=0.05为标准，不具有统计学显著性差异。A、B两组间比较结果：A组输液致死时间长于B组(p=0.006)，致死输钾量无统计学显著性差异(p=0.062)；全血钾、血清钠、镁及氯离子浓度变化值具有显著差异，血清钾、钙、碳酸氢根离子浓度变化值无明显的差异；尿量和尿液各电解质浓度指标无统计学显著性差异。
