초록

본 연구에서는 미세먼지로 유도될 수 있는 질환에 대한 예방 소재로써 청각(C. fragile)의 산업적 활용 가능성을 확인하고자 하였다. 청각의 총 페놀성 화합물 함량 및 지방질과산화 억제 효과는 40% 에탄올 추출물이 가장 우수한 결과를 나타냈고, 총 polysaccharide 함량에서는 물 추출물이 가장 높은 함량을 나타냈다. 미세먼지 유도성 산화적 손상에 대한 비강(RPMI2650), 폐(A549), 뇌신경(MC-IXC), 해마(HT-22), 미세아교(BV-2)세포에서의 세포보호 효과를 검증하기 위하여 세포 내 ROS 형성 억제 효과와 세포사멸 억제 효과를 측정하였다. 세포 내 ROS 형성 억제효과 실험 결과에서 40% 에탄올 추출물이 전반적으로 우수한 활성을 나타내는 것으로 확인되었다. 세포사멸 억제 효과 실험 결과에서는 물 추출물이 전반적으로 우수한 세포 생존율을 나타냈고, 40% 에탄올 추출물은 뇌신경세포(MC-IXC)을 제외한 세포에서 사멸 억제 효과가 미비하거나 농도가 높아짐에 따라서 세포독성을 일부 갖는 것으로 확인되었다. 결과적으로, 청각 추출물은 비강, 폐, 뇌(신경, 해마, 미세아교) 세포에서 미세먼지로 유도된 산화적 손상을 효과적으로 억제할 수 있는 천연 소재로서 산업적 활용 가능성이 기대된다.

To evaluate the protective effect of Codium fragile on fine dust (PM2.5)-induced cytotoxicity, we investigated its antioxidant activity and cell protective effect on PM2.5-exposed cells. The 40% ethanolic extract of C. fragile showed the highest total phenolic content, whereas the water extract of C. fragile showed the highest total polysaccharide content. The protective effect of the extracts on PM2.5-induced oxidative damage in nasal cavity (RPMI2650), lung (A549), brain (MC-IXC), hippocampus (HT-22), and microglia (BV-2) cells was evaluated by measuring the intracellular reactive oxygen species (ROS) content and cell viability. The results showed that the 40% ethanolic extract more efficiently inhibited ROS production than the water extract. In contrast, PM2.5-exposed cells treated with the water extract showed higher viability than those treated with the 40% ethanolic extract.
