Objectives :Ohyaksungi-san(Wuyaoshunqi-san) has been used for many years as a treatment for cerebrovascular diseases in Oriental medicine. This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san) on cognition and motor function recovery after ischemic brain injury, and also the expression of BDNF in hippocampus.
Methods :This study was designed with 4 subgroups to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san). As control groups, group Ⅰ has no treatment during 1 week after ischemic brain injury and group Ⅱ has no treatment during 2 weeks after ischemic brain injury. As experiemntal groups, group Ⅲ has been treated with Ohyaksungi-san(Wuyaoshunqi-san) during 1 week after ischemic brain injury and group Ⅳ have treated with Ohyaksungi-san(Wuyaoshunqi-san) during 2 week after ischemic brain injury. Each group has been examined by tests as follows, neurological motor behavioral tests, cognitive motor behavior test and histological test. Neurological motor behavior tests consisted of limb placement test, beam-walking test and horizontal wire test. Cognitive motor behavior test was performed by using Morris water maze. In the histological test, TTC(2,3,5-triphenylteterazolium chloride) staining, hematoxylin & eosin staining, and immunohistochemical staining were used.
Results :1. The tests for motor function recovery change had significantly good result in the experimental groups as compared with control groups(p<.05). 2. The Morris water maze test on cognition also had significantly good result in the experimental groups as compared with control groups(p<.05). 3. In the immunohistochemical staining for the expression of BDNF in hippocampus, more immune reaction was investigated in the experimental groups as compared with control groups. Especially group Ⅳ has the greatest immune reaction.
Conclusion :Ohyaksungi-san(Wuyaoshunqi-san) has good effects on cognition and motor function recovery after ischemic brain injury, and also the expression of BDNF in hippocampus.
