뇌 허혈 시 신체에 어떠한 영향을 주는가? | 즉, 뇌혈관이 막혀 뇌조직에 산소와 영양분의 공급이 원활하지 못하여 신경이 손상됨으로써 일어나는 질환인 것이다. 뇌 허혈 시 허혈 중심부(core)는 심한 허혈 손상으로 신경세포막이 파괴되어 괴사형태의 세포사멸(apoptosis)이 유발되고, 허혈 주변부(penumbra)는 소량의 산소와 포도당만 공급(10~20 ㎖/100 g/min)됨으로써 세포기능이 일시적으로 정지되는 상태에 빠지게 된다. 따라서 허혈 주변부 세포들은 혈류가 다시 공급되면 기능이 회복되거나, 재관류 조직손상(reperfusion injury)또는 지연성 세포사멸이 일어나게 된다3). | |
쇠무릎의 뿌리의 생리활성 성분에는 무엇이 있는가? | 그 외 우슬은 이뇨, 진통, 소중, 구어혈 등의 치료에 사용되고 있으며, 항염증, 항암작용, 간보호, 항산화 등의 생물학적 활성도 보고되고 있다17-19). 또한 우슬의 생리활성 성분으로 oleanolic acid, saponin, metamorphosis hormone, inokosterone, ecdysone, polysaccharide, 20-hydroxyecdysone, steroid 계열인 β-sitosterol, stigmasterol, rubrosterone 등이 보고되어 있다20,21,) | |
뇌경색은 무엇인가? | 뇌경색(ischemia)은 뇌의 동맥이 막히거나 파열됨으로써 뇌 조직의 죽음을 초래하는 뇌혈관 질환으로 뇌 손상뿐 아니라 알츠하이머병이나 간질 등의 다양한 신경학적 장애를 수반하는 중요 뇌질환 중 하나이다1-2). 즉, 뇌혈관이 막혀 뇌조직에 산소와 영양분의 공급이 원활하지 못하여 신경이 손상됨으로써 일어나는 질환인 것이다. |
