石斛에 관한 여러 실험적 연구는 어떤 효능을 보고하였는가? | 石斛에 관한 실험적 연구로 항산화 작용,13) 골다공증 예방효과,14) 면역조절 효과,15) 항염증 효과,16) 신경계질환 예방효과17) 및 신경세포 보호효과18) 등이 보고되었다. | |
뇌부종이 ICH의 임상예후판단 지표가 되는 이유는 무엇인가? | 1) ICH로 인한 신경학적 손상은 물리적인 뇌조직의 직접손상, 세포독성에 의한 세포자연사(apoptosis)와 괴사(necrosis), 혈관성으로 생기는 뇌부종및 염증반응 등을 들 수 있다.2,3) 특히 뇌부종은 ICH를 포함한 여러 뇌조직 손상에서 뇌혈관장벽(Blood-Brain Barrier, BBB)의 손상과 뇌조직의 염증반응으로 인해 발생하는데,4,5)임상증상을 악화시키는 주요 인자일 뿐만 아니라 임상예후판단의 지표가 된다.6) 뇌조직의 출혈은 살균성과 반응이 빠른 산화제(reactive oxidant)인 MPO-H2O2-Cl-system의 차아염소산(hypochlorous acid)과 차아염소산염(hypochlorite)을 생산하여 염증반응을 지속시키고 확장시키는 MPO를 특징적으로 발현하는 중성백혈구의 침윤을 동반한다. | |
뇌출혈에 의한 신경학적 손상에는 어떤 것들이 있는가? | 뇌출혈(intracerebral hemorrhage, ICH)은 뇌의 국소적인 부위에서 일어나고 지주막하출혈(subarachnoid hamorrhage)보다 두 배의 유병율을 보이고 있다.1) ICH로 인한 신경학적 손상은 물리적인 뇌조직의 직접손상, 세포독성에 의한 세포자연사(apoptosis)와 괴사(necrosis), 혈관성으로 생기는 뇌부종및 염증반응 등을 들 수 있다.2,3) 특히 뇌부종은 ICH를 포함한 여러 뇌조직 손상에서 뇌혈관장벽(Blood-Brain Barrier, BBB)의 손상과 뇌조직의 염증반응으로 인해 발생하는데,4,5)임상증상을 악화시키는 주요 인자일 뿐만 아니라 임상예후판단의 지표가 된다. |
