참당귀(Angelica gigas Nakai)의 체력증진 및 면역조절효과

The Regulatory Effect of Angelica gigas Nakai on Immune Enhancement and Cytokine Production in vivo and in vitro

본 연구에서는 다양한 실험모델을 활용하여 참당귀 추출물의 면역조절 효능을 평가하였다. 특히 강제수영부하실험에서참당귀 추출물의 경구투여는 부동시간의 감소 및 신장기능 지표인 BUN 및 근육의 피로관련 생화학적 지표인 LDH 활성 조절로 체력증진 효과를 나타내는 것으로 확인하였다. T세포를 활용한 참당귀 추출물의 면역조절 효능 평가를 위하여 IL-2, IL-4 및 IFN-γ mRNA 발현 변화에 대한 영향을 측정하였다. 실험결과, 참당귀 추출물은 IL-2, IL-4 및 IFN-γ세포 활성물질의 생성 조절을 통하여 면역조절 효능이 있음을 확인하였다. 본 연구결과를 통해 규명된 결과는 참당귀 추출물의 체력증진 및 면역조절을 위한 건강 기능성 제품개발에 활용 가능성을 제시하였다

Natural products are important sources for drug development because they have a wide variety of useful biological properties. Angelica gigas Nakai (AGN) has been used as an herbal medicine for treatment of colds, pain, and anemia. The present study was designed to evaluate the regulatory effect of AGN on immune enhancement in vivo and in vitro. To investigate the immune-enhancing effect of AGN, we used forced swimming test (FST) experimental model. Mice were orally administered by AGN or distilled water for 14 days and then immobility time and biological parameters in serum were measured. The results showed that immobility time in AGN treatment group was significantly reduced in comparison with the control group. Plasma levels of blood urea nitrogen and lactate dehydrogenase in AGN group was significantly decreased compared with control group. Additionally, we showed that AGN treatment significantly increased immunerelated cytokines such as interleukin (IL)-4, IL-2, and interferon (IFN)- levels in Molt-4 cells. Collectively, the findings provide experimental evidence that AGN may be effective in improving immune function.
