[Study on pharmacokinetics-pharmacodynamics correlation of Danshensu in rats with focal cerebral ischemia].

To study the pharmacokinetic process of Danshensu in cerebal ischemia injury model rats and the correlation with its anti-cerebral ischemia effect. In this study, the middle cerebral artery occlusion (MCAO) model was established, in which all of the rats were intravenously injected of Danshensu at a single dose of 40 mg x kg(-1). The HPLC-DAD method was applied to determine the plasma concentration of Danshensu at different time points and draw the drug-time curve.
