Objective: This study was to investigate the effects of Banhabaekchulchunma-Tang(BCT) on Dementia induced by focal ischemic injury in the rats.
Method:Experimental groups were divided into 4 groups ; Normal group, Control group, BCT1 group and BCT2 group. Control group were no treated after focal brain ischemic injury. BCT1 group were administered BCT 0.3 ml/kg to focal brain ischemic injuried rats for 21 days, BCT2 group were administered BCT 1.2 ml/kg to focal brain ischemic injuried rats for 21 days. The present author observed the number of errors on the eight-arm radial maze task , the rate of correct choice on the eight-arm radial maze task, the values of density of Cresyl Violet-stained sections in the hippocampal CA1 and the values of density of Acetlycholin Esterase(AchE) stained nuclei in the hippocampal CA1.
Results: 1. The number of errors in the eight-arm radial maze task was significantly decreased in BCT1 group on 1-6th days. And it was significantly decreased in BCT2 group on 1st, 2nd, 3rd and 6th day compared with control group. 2. The rate of correct choice on the eight-arm radial maze task was increased in BCT1 group and BCT2 group compared with control group, but the value was not significant. 3. The values of density of Cresyl Violet-stained sections in the hippocampal CA1 were significantly increased in BCT1 group and BCT2 group compared with control group. 4. The values of density of AchE stained nuclei in the hippocampal CA1 were significantly increased in BCT1 group compared with control group.
Conclusion: The present author thought that Banhabaekchulchunma-Tang could be used to cure dementia derived by the phlegm retention of fluid.
