질경이의 메탄올 추출물은 인체유방암 세포주인 MDA-MB-231 세포주의 암세포 생존율을 농도 의존적으로 감소시켰다. 특히 24시간 치료 후 농도 600 ug/ml에서 액 80%의 억제효과를 나타냈다. iNOS의 발현은 농도 200, 400ug/ml 에서 약 50%의 억제효과를 나타냈고, COX-2 ,발현억제효과는 나타나지 않았다.. 질경이의 열수 추출물에서는 24시간 치료 후 농도 900 ug/ml에서 액 30%의 세포 생존율 억제효과를 나타냈으며, COX-2, iNOS 발현억제효과는 나타나지 않았다.
질경이 추출물은 인체 유방암 세포주인 MDA-MB-231의 세포생존율 억제효과가 있었으며 iNOS의 발현도 억제하였다. 향후 보다 다양한 임상효과를 확인하기 위하여 질경이의 정제 실험 및 동물 실험 등의 연구가 필요하다고 생각한다.|Methanol Extracts of Plantago Asiatica Cell survival rate decrease depending on concentration, especially, it reduced about 80% cell survival rate at the log of 600 ug/ml shows the effect of suppression after treatment for 24 hours significantly. The expression of iNOS suppressed 200, 400ug/ml of concentration about 50%. But expression of COX-2 was not suppressed. Hot water Extracts of Pantago Asiatica cell survival rate decrease depending on concentration. However, it reduced about 30% cell survival rate at the log of 900 ug/ml after treatment for 24 hours. The expression of iNOS, COX-2, there was no significant effect of the inhibition. So, it can be concluded that Plantago Asiatica have an inhibitory effect on MDA-MB-231 human breast cancer cells. It was expected that animal experiments and isolation and purification test of Plantago Asiatica would bring out more variety of clinical effects.
