소속명탕(小續命湯) 추출물(抽出物)이 전뇌허혈(全腦虛血)및 국소뇌허혈(局所腦虛血)에 미치는 영향(影響)

The Effect of Sosokmyung-tang extract on Global cerebral ischemia·Cerebral Infarction by MCA occlusion in vivo

이 실험의 목적은 소속명탕(小續命湯)에 대하여 KCN(potassium cyanide)으로 유발된 혼수시간과 생존시간을 측정하여 전뇌허혈(全腦虛血)에 미치는 영향을 관찰하고, 또한 MCA occlusion 유발시 뇌부종율(腦浮腫率)과 뇌허혈면적(腦虛血面積)을 측정하여 국소뇌허혈(局所腦虛血)에 미치는 영향을 실험연구하였다. 1. 전뇌허혈 유발실험에서 유의성있는 KCN 유발 혼수시간의 단축, 치사량의 KCN에 대한 생존시간의 연장 효과가 나타났다. 2. 국소 뇌허혈 유발실험(MCA occlusion)에 미치는 효과에서는 뇌허혈면적과 뇌부종율이 대조군에 비하여 유의성있게 감소하였다.

The effects of Sosokmyung-tang(小續命湯) on global cerebral ischemia and cerebral in farction by MCA(middle cerebral artery) occlusion were evaluated in this study. This study was performed to investigate that Sosokmyung-tang would be useful for cerebrovascular diseases. In the case of global cerebral ischemia, ICR mice were used and divided into three group at random. Control group was treated after oral administration of normal saline, experimental group was treated after oral administration of 10.4mg/20g/day of Sosokmyung-tang extract. The multiple parameter of global cerebral ischemia included the duration of coma of KCN(potassium cyanide)-injected(1.2mg/kg, i.v) group and the survival time of KCN-injected(3.0mg/kg, i.v) group. In the case of cerebral infarction by MCA occlusion, Sprague-Dawley rats were used and divided into three group at random. Control group was given nothing before MCA occlusion, experimental group was given 157.2mg/250g/day of Sosokrnyung-tang extract before MCA occlusion. We investigated edema and ischemic ratio in 8 slices of rats' brain after MCA occlusion. The results were obtained as follows : 1. Sosokrnyung-tang significantly shortened the duration of coma of KCN-injected(1.2mg/kg,i.v) group and lengthened the survival time of KCN-injected(3.0mg/kg, i.v) group. 2. Sosokmyung-tang significantly decreased cerebral edema and ischemic ratio in rats after MCA occlusion. From the above results, it was concluded that Sosokmyung-tang can be effectively applied to cerebrovascular diseases.
