Laborotary study of DanHong in improving the movement function after stroke / 局解手术学杂志

ABSTRACT

Objective To investigate Danhong in improving the movement function of reperfused rat after stroke. Methods Rats to make middle cerebral artery occlusion model,after 24 hours of reperfusion were divided into control group,high dose and low dose of Danhong groups and Venorruton group randomly. Rats in Control group were injected saline. High and low dose group were injected DanHong according to their weight,high dose as 14. 4 mg/kg,low dose as 3. 6 mg/kg. Venorruton group were injected Venorruton as 0. 04 g/kg. The infarcted square of rat brain was measured,the rats were tested with walking wood bar and two fore limb grasp strength. Results Rat infarcted squre in 24 hours and 3 days,control groups is the biggest,compared with others,there are statistically difference(P<0. 05). Score in each group of walking wood bar in 3rd days are (1. 30 ± 0. 91),(3. 78 ± 1. 72),(4. 18 ± 2. 05),(4. 63 ± 2. 45). Compared between control and other druge groups,there are statistically differnec(P<0. 05). There are statistically differences between control and other groups in two fore limb grasp testing(P<0. 05). Conclusion Danhong has the same effect which can improve the movement function to stroke rat as Venorruton.
