疏風湯이 고지혈증 흰쥐의 뇌경색에 미치는 영향

Abstract

Objectives : This study evaluates the neuroprotective effects of Sopung-tang, a mixture of Notopterygii Rhizoma, Saposhnikoviae Radix, Angelicae Gigantis Radix, Cnidii Rhizoma, Hoelen, Aurantii Nobilis Pericarpium, Pinelliae Tuber, Linderae Radix, Angelicae Dahuricae Radix, Cyperi Rhizoma, Cinnamomi Ramulus, Asari Radix, Glycyrrhizae Radix on the cerebral infarct combined with hyperlipidemia. Method : The hyperlipidemia was induced by the beef tallow 30% diet for 14 days on Sprague-Dawley rats. The cerebral infarct was induced by the middle cerebral artery occlusion (MCAO) for 2 hours with intraluminal thread method. Then the water extract of Sopung-tang was administered a day for 5 days at 3 hours after the cerebral infarct by MCAO. Effect of Sopung-tang was evaluated with the infarct volume and edema percentage by a TTC-stained brain section, and the expressions of Bax and Bcl-2 in the brain tissue by a immunohistochemical stain method. Results : Sopung-tang reduced the infarct size partly in a TTC-stained brain section of the hyperlipidemic MCAO rats. Sopung-tang reduced the infarct volume of the hyperlipidemic MCAO rats significantly. Sopung-tang reduced the edema percentage of the hyperlipidemic MCAO rats, but not significant statistically. Sopung-tang suppressed the Bax expressions in the cerebral penumbra and caudate putamen of the hyperlipidemic MCAO rats significantly. Sopung-tang upregulated the Bcl-2 expression in the caudate putamen of the hyperlipidemic MCAO rats. Conclusion : These results suggest that Sopung-tang plays an anti-apoptotic neuroprotective effect through the suppression of Bax and up-regulation of Bacl-2 expressions in the brain tissues.
