보중익기탕(補中益氣湯) 추출물의 대식세포 분화 유도 효과

본 실험에서는 생쥐에서 분리한 골수 세포의 분화에 보중익기탕 추출물이 미치는 영향을 알아보았다. GM-CSF와 IL-3는 대식세포의 형성을 자극하는데 관여한다. 보중익기탕 추출물을 첨가하였을 때 GM-CSF와 IL-3로 분화하는 colony의 수를 증가시키는 것을 알 수 있었으며 anti-CD11b 항체로 염색한 결과 분화한 세포는 대식세포의 특이적 세포표면 단백질인 CD11b(Mac-1)를 발현하고 있었다. 또한 보중익기탕 추출물은 대식세포가 생산하는 IL-6와 일산화질소(nitric oxide)의 분비량도 증가시키는 것을 알 수 있었다. 이상의 실험 결과, 오래전부터 전통 처방제로 사용되어온 보중익기탕 추출물은 대식세포의 분화와 증식을 유도하는데 효과가 있는 것으로 생각된다. We have investigated the effects of Bu-Zhong-Yi-Qi-Tang on the differentiation of murine bone marrow cells in methylcellulose culture. GM-CSF and IL-3 supported primarily the formation of granulocyte/mac- rophage colony formation. However, the addition of Bu-Zhong-Yi-Qi-Tang extract yielded a significant increase in the numbers of colonies and differentiated cells in the presence of GM-CSF and IL-3. We have analyzed CD11b (Mac-1) expression of differentiated cells from bone marrow by staining with monoclonal anti-CD11b antibody. The majority of colony-forming cells were in CD11b^+ population. Also Bu-Zhong-Yi-Qi-Tang extract promoted the production of IL-6 and nitric oxide by macrophages. These results demonstrate that extract of Bu-Zhong-Yi-Qi-Tang, a prescription of traditional oriental medicine, is effective in supporting macrophage potential of the primary colonies.

In our previous study, a novel herb mixture (HIM-Ⅰ) of Angelica gigas radix, Cnidium officinale rhizoma, and Paeonia japonica radix was developed to protect the intestinal and immune systems and to promote their recovery from radiation damage. A new herbal composition (HemoHIM) with the high immune modulating activity was developed from HIM-Ⅰ. In the present study, we examined the effects of HemoHIM on the maturation process of murine bone marrow (BM)-derived dendritic cells (DC). BM cells were cultured in the presence of IL-4 and GM-CSF and the generated immature DC were stimulated with HemoHIM for 24 hours. HemoHIM significantly enhanced the expression of co-stimulatory molecules, CD80 and CD86, especially. The activation capacity of HemoHIM-treated DC was significantly higher than that of immature DC, as analyzed by IL-2 and IFN-γ production and proliferation of the responding T cells in the co-culture with allogeneic T cells. The antigen-presenting capacity of HemoHIM-treated DC was also increased by the co-culture with OVA-specific T cells (HS-1), as analyzed by IL-2 and IFN-γ production and the proliferation. These results indicate that HemoHIM causes the maturation and activation of DC, which may be a part of mechanisms of immunomodulation by HemoHIM.

과산화수소의 산화적 스트레스로 유도된 Apoptosis에 대한 생약복합조성물(HemoHIM)의 방호효과 평가

본 연구팀에서는 방사선으로부터 위장관과 면역조혈계를 방호하기 위하여 당귀, 천궁, 백작약으로 새로운 생약복합물 HIM-I을 개발하였고, HIM-I을 에탄올 침전하여 에탄올 분획(HIM-I-E)과 조다당 분획(HIM-I-P)을 얻은 후, HIM-I에 조다당 분획을 첨가하여 HemoHIM을 제조하여 실험하였으며, 과산화수소를 이용하여 산화적 스트레스를 유발한 후 HemoHIM의 apoptosis 억제 효과를 측정하였다. 과산화수소를 세포주에 처리한 결과 세포독성 증가, 세포막 파괴, subG1기 세포 증가, DNA 절단 현상 등이 관찰되었다. 이때 HIM-I, HIM-I-P, HemoHIM을 첨가하여 전처리 배양한 다음에 과산화수소로 apoptosis를 유도하였다. 그 결과 과산화수소에 의한 세포독성, 세포막 파괴, subG1기 세포, DNA 절단현상 등이 현저하게 감소하는 것으로 나타났다. 전반적으로 HemoHIM의 방호 효과는 HIM-I-P와 비슷하였으며 HIM-I보다 높은 것으로 나타났다. 이상의 결과로 HemoHIM은 면역기능 방호?회복 물질로서 뿐만 아니라 산화적 스트레스에 대한 항산화제로서 유용하게 활용될 수 있을 것으로 생각된다. In our previous study, a novel herb mixture (HIM-I) of Angelica gigas radix, Cnidium officinale rhizoma, and Paeonia japonica radix was developed to protect the intestinal and immune systems and promote its recovery against radiation damage. A new herbal composition (HemoHIM) with the high immune modulating activity was developed from HIM-I. HIM-I was fractionated into ethanol fraction (HIM-I-E) and polysaccharide fraction (HIM-I-P). And HemoHIM was prepared by adding HIM-I-P to HIM-I. HemoHIM showed more effective than HIM-I in immune modulation as well as radioprotection. The present study is designed to investigate the protective effects of HIM-I, HIM-I-P, and HemoHIM on hydrogen peroxide (H₂O₂)-induced apoptosis of human promyelocytic leukemia (HL-60) cells. It was shown that H₂O₂ treatment reduced the viability of cells, and increased appearance of DNA ladders, hypodiploid (subG1) cells, and phosphatidylserine translocation level. Pretreatment of HemoHIM significantly reduced the cytotoxic effect induced by H₂O₂, associated with reducing the translocation of phosphatidylserine, hypodiploid cells and DNA ladders. HemoHIM appeared to be more protective than HIM-I against H₂O₂-induced apoptosis whereas, it exhibited similar activity to HIM-I-P. These results indicated that HemoHIM might be an useful agent for protection against oxidative stress (H₂O₂)-induced apoptosis as well as immune modulation, especially since it is a relatively nontoxic natural product.
