  • A kind of traditional herbal prescription, Sip-Jeon-Dae-Bo-Tang (TJ-48), has been reported to improve the general condition of cancer patients receiving chemotherapy and /or radiation therapy, and to accelerate hematopoietic recovery from bone marrow injury by mitomycin C. In the present studies, we found that hot-water extract from Atractylodes lancea DC. rhizomes contributed mainly to intestinal immune modulating activity of TJ-48 on Peyer's patch cells mediated-hematopoietic response. After the fractionation, ALR-5 II a-1-1, 5 II b-2-2 and 5 II c-3-1 were further purified from crude polysaccharide fraction. Chemical analyses of each fraction indicated that ALR-5 II a-1-1 mainly contained arabinogalactan fraction whereas ALR-5 II b-2-2 and 5 II c-3-1 mostly comprised pectic polysaccharide fractions as the active polysaccharide ingredients. In order to analyze the essential structure of the activity, ALR-5 II a-1-1 was treated by sequential enzymatic digestion using exo-${\alpha}$-L-arabinofuranosidase and exo-${\beta}$-D-(1\longrightarrow3)-galactanase. Based upon the results of chemical and MALDI-TOF-MS analyses and activity on the digested fractions, the galactosyl side chains consisting of 6-linked Galf and Galp over tetrasaccharide in ALR-5 II a-1-1 might be responsible for the potent intestinal immune modulating activity. To characterize moiety of ALR-5 II c-3-1 for the expression of activity, endo-${\alpha}$-D-(1\longrightarrow4)-polygal acturonase (GL-PGase) purified from dried leaves of Panax ginseng digested ALR-5 II c-3-1. The results of structural analyses and activity on the digested fractions showed that PG-2, which structurally resembles to rhamnogalacturonan II (RG II), and PG-3 (galacturono-oligosaccharides) contained potent intestinal immune modulating activity. Further purification of the other acidic fraction (ALR-5 II b-2-2) indicated that ALR-5 II b-2-2Bb showed that the most potent activity. ALR-5 II b-2-2Bb also contained the unusual component sugars characteristics in RG- II as well as PG-2 derived from ALR-5 II c-3-1, but it could not be digested with GL-PGase. The present studies of relationship between structures and intestinal immune modulating activity of the active polysaccharides purified from A. lancea DC. rhizomes suggested that neutral galactosyl chains consisting mainly of (1\longrightarrow6)-linked Galf and Galp, and RG- II -like moiety with unique component sugars, such as 2-Me-Xyl, 2-Me-Fuc, Api, AceA, Kdo and Dha should play an important role in the potent intestinal immune modulating action of A. lancea DC. rhizomes.

  • To elucidate new biological ingredients in cold-brew coffee extracted with cold water, crude polysaccharide (CCP-0) was isolated by ethanol precipitation, and its immune-stimulating activities were assayed. CCP-0 mainly comprised galactose (53.6%), mannose (15.7%), arabinose (11.9%), and uronic acid (12.4%), suggesting that it might exist as a mixture of galactomannan and arabinogalactan. CCP-0 significantly increased cell proliferation on both murine peritoneal macrophages and splenocytes in a dose dependent manner. CCP-0 also significantly augmented nitric oxide and reactive oxygen species production by murine peritoneal macrophages. In addition, macrophages stimulated by CCP-0 enhanced production of various cytokines such as tumor necrosis factor-${\alpha}$, interleukin (IL)-6, and IL-12. In an in vitro assay for intestinal immune-modulating activity, CCP-0 showed higher bone-marrow cell-proliferation activity through Peyer's patch cells at $100{\mu}g/mL$ than the negative control. These results suggest that CCP-0 may potentially enhance macrophage functions and the intestinal immune system.

  • The prescriptions (DB-1-DB-5) were prepared with the active herbal medicines, Acanthopanax senticosus, Glycyrrhiza uralensis, Polygonatum odoratum, and Cichorium intybus. The most active crude polysaccharide fraction (DB-2-3), which was isolated through the fractionation of hot-water extract from DB-2, was significantly reduced by periodate oxidation (52.7 and 63.7%) on intestinal immune system modulating and anticancer activity. When DB-2-3 was further fractionated by column chromatographies, DB-2-3IIc-2 showed the most potent activities. In addition, DB-2-3IIc stimulated the proliferation of bone marrow cells via Peyer's patch in dose-dependent pattern by oral administration. The metastasis of colon 26-M3.1 lung carcinoma had significantly inhibited in mice fed DB-2-3IIc at 1 mg/mouse (43.8%). DB-2-3IIc-2 mainly contained uronic acid (46.1%) and 42.5% of neutral sugar with a small amount of protein (7.6%), and component sugar analysis also showed that DB-2-3IIc-2 was composed Ara, Gal, and GalA (molar ratio; 0.50:0.63:1.00). It may be suggested that activities of DB-2-3IIc-2 are resulted from pectic polysaccharides containing a polygalacturonan moiety with side chain of neutral sugars, such as Ara and Gal.

  • Macrophage is the important cell for the immune system. Many of herbal drugs were searched about their immune-modulating activity. The purpose of this study is to investigate the biological effect of water extract from ARTEMISIAE ARGI FOLIUM (WAAF) on mouse macrophage Raw 264.7 cells. ARTEMISIAE ARGI FOLIUM was known to have the antibacterial, immune-enhancing, and anticoagulative properties. Cytotoxicity of WAAF was verified by MTT assay. The intracellular production of hydro peroxide ($H_2O_2$) by WAAF was examined. The productions of nitric oxide (NO) and $TNF-{\alpha}$ from Raw 264.7 cell by WAAF were also examined. WAAF showed no cytotoxicity on RAW 264.7 cells for 3 hours. WAAF increased the production of $H_2O_2$ in Raw 264.7 cells. WAAF decrease the production of NO from the cells at low concentrations but increased at high concentrations. WAAF increased the production of $TNF-{\alpha}$ from the cells. Therefore, It could be suggested that WAAF has the immune-modulating effect.

  • 십전대보탕의 10가지 구성 천연물을 열수추출하여 장관면역 활성을 비교 검토한 결과, 창출(Atractylodes lancea DC., ALR)과 인삼(Panax ginseng C.A. Meyer, PG)에서는 높은 활성을 나타내었으나 약한 활성을 갖는 황기(Astragalus membranacues, ASR)와 당귀(Angelica aculiloba Kitagawa, AR)를 제외하고는 어떤 생약에서도 거의 활성을 갖지 않았다. 한편 이러한 활성을 가진 생약(ALR, PG와 ASR) 중에서도 특히 ALR만이 종류, 생산지 및 육종조건에 관계없이 항상 일정하게 높은 활성을 보여주어 창출의 열수추출물 획분(ALR-0)이 십전대보탕의 장관면역 활성에 중요하게 관여하는 시료로 선정되었다. ALR-0 획분은 다시 용매별로 분획되어 메탄올-가용성 획분(ALR-1), 메탄올-불용성/에탄올-가용성 획분(ALR-2) 및 조다당 획분(ALR-3)으로 조제되었으며 이들의 활성을 측정한 결과, 단지 ALR-3 획분만이 Peyer's patch를 통한 골수세포의 증식을 활성화시키는 장관면역 활성을 시료농도에 의존적으로 나타내었으며 그 외의 획분에는 활성이 거의 없었다. 한편 ALR-3 획분을 $NaIO_4,\;NaClO_2$ 및 pronase로 처리한 후 활성을 측정한 결과, 모든 처리군에서 활성이 감소되었으며 특히 periodate 산화에 의해 심한 활성감소를 보였다. 이러한 결과를 토대로 십전대보탕의 장관면역 활성은 10종의 생약 중에서도 특히 창출이 중요하게 활성에 관여하는 것으로 보이며 다양한 용매별 분획을 통해 저분자보다는 에탄올에 침전된 고분자가 주요 함유물질인 조다당 획분이 장관면역 활성에 관여하는 것으로 추정되었다. 또한 periodate 산화에 의해 활성이 크게 감소되는 것으로 보아 주로 다당류가 창출의 장관면역에 중요한 활성물질인 것으로 생각된다.

  • Background and Aims : Even though various strategies for cancer treatment have advanced with the remarkable development of genomic information and technology, it is far from giving relief to cancer patients. Recently there is accumulating evidence that the immune system is closely connected to anti-tumor defense mechanisms in a multistage process. This includes tumorigenesis, invasion, growth and metastasis. Cordyceps Militaris, a well-known oriental herbal medicine, is a parasitic fungus that has been used as an immune enhancing agent for a long period of time. However, little is known about the cancer-related immunomodulatory effects and anti-tumor activities. In the present study, we aimed to investigate the effects of Cordyceps Militaris extract (CME) on immune modulating and anti-tumor activity. Materials and Methods : To elucidate the effects of CME on macrophage and natural killer (NK) cell activity, we analyzed nitric oxide (NO) production, NK cytotoxicity and gene expression of cytokines related with macrophages and NK cell activity. Results and Conclusions : CME activated and promoted macrophage production of NO. It also enhanced gene expression of IL-1 and iNOS in RAW 264.7 cells. CME promoted cytotoxicity of NK cells against YAC-1 cells and enhanced NK cell related gene expression such as IL-1, IL-2, IL-12, iNOS, IFN-${\gamma}$ and TNF-${\alpha}$ in mice splenocytes. It also Promoted protein expression of IL-10, IL-12, IFN-${\gamma}$ and TNF-${\alpha}$ in mice splenocytes and inhibited lung tumor metastasis induced by CT-26 cell line compared with the control group. From these results, it could be concluded that CME is an effective herbal drug for modulating the immune system and anti-cancer treatment by promoting macrophage and NK cell activity.

  • 90여종의 전통차 및 죽류용 식물로부터 조제된 다양한 용매추출물 중에서, 귤피(peels of C. unshiu)의 냉수추출물 (CUI-0)이 Peyer’s patch를 매개로 한 가장 높은 장관면역 활성을 나타내었으며 다시마(L. japonica), 둥글레(P. japonicum), 탱자(P. trifoliata)의 냉수추출물과 구기자(L. chinense) 및 치자(G. jasminoides)의 열수추출물을 제외한 나머지 식물의 용매추출물은 거의 활성을 가지지 못하였다. CUI-0는 MeOH-가용성 획분(CUI-1), MeOH-불가용성이면서 EtOH-가용성 획분(CUI-2)과 조다당 획분(CUI-3)으로 분획되었다. 이러한 획분들 중 CUI-3은 Peyer’s patch 세포를 매개로 하는 골수세포 증식의 자극활성이 가장 높았으며 arabinose, galacturonic acid, galactose, glucose, glucuronic acid와 rhmanose(molar ratio; 1.00:0.53:0.45:0.28:0.28:0.19) 등을 주요 구성당으로 함유하고 있었으며 소량의 단백질(9.4%)도 구성물질로 포함된 활성 획분임이 밝혀졌다. CUI-3의 장관면역 활성은 pronase 및 periodate 처리에 의해 감소되었으며 특히 periodate 산화는 CUI-3의 활성에 심각한 영향을 끼치는 것을 알 수 있었다. 활성 획분으로서 당 함량이 높은 CUI-3IIb-3-2는 DEAE-Sepharose FF, Sepharose CL-6B 및 Sephacryl S-200에 의해 귤피 냉수추출물의 조다당 획분으로부터 정제되었으며 HPLC에 의해 분자량 약 18,000 Da의 단일 peak임을 확인하였다. CUI-3IIb-3-2는 주로 arabinose, galactose, rhamnose, galacturonic acid와 glucuronic acid(molar ratio; 1.00:0.54:0.28:1.45:0.63) 등의 구성당으로 구성되어져 있었으며 소량의 단백질(3.2%)이 함유되어진 물질로 구성되어 있었다. 한편 CUI- 3IIb-3-2는 Peyer’s patch를 경유하였을 때만 골수세포 증식활성을 나타내었으며 활성물질 자체가 직접 골수세포 증식활성에 관여하지는 않는것으로 확인되었다. 이러한 결과로부터 귤피의 장관면역 활성은 측쇄에 arabinose와 galactose 등의 중성당이 결합된 polygalacturonan 구조를 갖는 펙틴계통의 다당류에 기인하고 있음을 보여주었다.

  • Purified compound with intestinal immune system-modulating properties, GWE-2c, was isolated from methanol extract of Gelidium amansii by sequential procedures with silica gel column, LH-20 Sephadex gel column, and thin-layer chromatographies. In the presence of GWE-2c, strong immunoactivity in Peyers patch cell-mediated bone marrow cells was observed in vitro. In vivo intestinal immune-modulating activity was also enhanced by crude phenolic compound (GWE) of G. amansii in a dose-dependent manner. Investigation of production of several cytokines in Peyer's patch cells upon stimulation with GWE in vivo revealed the levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-6 increased. Results suggest that the phenolic compound from G. amansii represents immunopotentiator and biological response modifier at in vitro and in vivo levels.

  • The scope of the research is investigation of immune-modulating activities of A. rugosa (Baechohyang) extract was preformed through the screening active constituents using in vitro assays and evaluating anti-inflammatory activity and anti-atherosclerotic activity of the extract and active compound (tilianin) in vivo. In addition, various functional foods using the extract and whole plant was developed. The extract showed strong anti-inflammatory activity in carrageenan-induced acute edema mouse model and anti-atherogenic lesion activity in LDLR (low density lipoprotein receptor) deficient mouse model. These activities were thought to be resulted from modulation activity of several pathways of inflammation process. Among the main constituents of Baechohyang, polyunsaturated fatty acids (PUFA), Phytosterols, oleanolic acid and rosmarinic acid showed anticomplement activity, and PUFA, acacetin and tilianin newly showed potent ICAM-1 expression inhibition activity. The processes of extraction, mixing ratio of additives and storage conditions were established for drinks, granule tea, leaf tea, mixed tea and furigake.
