丹蔘이 뇌조직출혈 흰쥐의 신경세포 자연사에 미치는 영향

Abstract

Objects : The purpose of this study was to observe the effect of Salviae Miltriorrhiza Radix(SMR) water-extract on intracerebral hemorrhage(ICH) and neuronal apoptosis in the injured areas. Method : ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. The rats were givened oral SMR treatment once a day for three days after the ICH treatment. TUNEL positive cells in the affected regions were performed by TUNEL assay, Bax and Bcl-2 positive cells by immunohistochemistry and the Bax expression by western blotting method. Results : The results are as follow;1. SMR significantly reduced the number of TUNEL positive cells in the peri-hematoma reigions of ICH-induced rats. 2. SMR significantly reduced the number of Bax positive cells in the peri-hematoma regions of ICH-induced rats. 3. SMR did not affect the number of Bcl-2 positive cells in the peri-hematoma regions of ICH-induced rats. 4. SMR significantly reduced the Bax expressions compared with ICH group in hemorrhagic hemisphere of ICH-induced rats. Conclusion : These results suggest that SMR is effective in reducing neuronal apoptosis.
