ABSTRACT
Objective To investigate neurological function, volume of cerebral infarction, changes of lipid peroxidation, and the intervention effect of compound angelica injection (CAI) on rats with focal cerebral ischemia injury. Methods Models of rat with cerebral ischemia were reproduced by middle cerebral artery occlusion (MCAO). All animals were randomly divided into sham-operation group, model group, CAI group, and edaravone group. 1 hour after the models were established, rats in the sham-operation group and model group received intraperitoneal injection with normal saline, while rats in CAI group and edaravone group received intraperitoneal injection with relevant medicine for continuing 7 days. Volume of cerebral infarction was detected by Tetrazole staining method, neurologic function were detected by neuroethology, and concentration of MDA in brain tissue was also detected. Results After 7-day cerebral ischemia, compared with the model group, volume of cerebral infarction in CAI group was significantly reduced (P<0.05), and the concentration of MDA was a little lower. Conclusion CAI has significant protective effects which can significantly improve neurological function, reduce volume of cerebral infarction, and alleviate the effects of lipid peroxidation of rats with focal cerebral ischemia injury.
