초록
한국특산 매자나무(Berberis Koreana Palibin)의 뿌리에서 분리한 majarine은 isoquinoline 알카로이드로서 본 교실에서는 중추신경계에 대한 약리작용을 검토하고 있다. Majarine을 마우스 복강내로 투여하여 직장온도 변화와 haloperidol, cyproheptadine과 reserpine 등에 대한 약물 상호작용을 관찰하여 다음과 같은 성적을 얻었다. Majarine은 마우스에 있어서 용량의존적으로 현저한 체온감소를 나타내었으나, 0.1 mg/kg투여시 체온증가의 유의성을 보였다. 체온감소는 haloperidol과 cyproheptadine으로 억제되었다. Reserpine처치 마우스에 있어서
Majarine that was isolated from Berberis Koreasra Palibin (Berberidaceae) is the isoquinoline alkaloid. The effects of dopaminergic and serotonergic antagonists on majarine induced changes in body temperature were studied in the mouse. Intraperitoneal administration of majarine produced dose-dependent hypothermia. At a dose of 0.1 mg/kg, majarine caused a slight increase in body temperature. Majarine-induced hyperthermia was attenuated by the 5-HT antagonist, cyproheptadine However, it caused hyothermia in mice pretreated with the DA antagonist, haloperidol, and hyperthermia in mice pretreated with haloperidol and cyproheptadine in comparision with haloperidol pretreatment. At a dose of 2.0 mg/kg, majarine-induced hypothermia was attenuated by haloperidol and cyproheptadine, respectively. In reserpine pretreated mice, majarine produced dose-dependent hypothermia. At a dose of 0.1 mg/kg, majarine pretreated with haloperidol caused no significant effect in body temperature. At a dose of 2.0 mg/kg, majarine-induced hypothermia was attenuated by haloperidol pretreatment in mice treated with reserpine and
