Objectives: This study aimed to examine the changes in ingredients according to its cultivation method by examining the content of saponin and non-saponin components of ginseng. Methods: Ginseng saponin component analysis was compared and reviewed using the high-performance liquid chromatography method, and acidic polysaccharide component was measured using the carbazole sulfuric acid method. Results: The comparative analysis of ginseng saponin content of 4 and 6 years old fresh ginseng showed the following results. According to the cultivation method, upland field cultivation fresh ginseng showed higher average content of crude saponin than paddy field cultivation fresh ginseng. Whereas, paddy field cultivation fresh ginseng showed higher average content of total saponin than upland field cultivation fresh ginseng. Ginsenoside Rb1 showed higher content of paddy field cultivation fresh ginseng than upland field cultivation fresh ginseng in 6 years old ginseng. However, it showed higher content of upland field cultivation fresh ginseng than paddy field cultivation fresh ginseng in 4 years old ginseng. Additionally, ginsenoside Rg1 showed higher content of paddy field cultivation fresh ginseng than upland field cultivation fresh ginseng in 6 years old ginseng, whereas upland field cultivation fresh ginseng showed higher content of paddy field cultivation fresh ginseng in 4 years old ginseng. The effect on the content of ginseng saponins and acidic polysaccharides according to paddy field and upland field cultivation methods is considered to be small. Conclusions: The paddy field cultivation method, which is more efficient in production cost due to depletion of farmland and long-distance cultivation, is considered to be an economical cultivation method.

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.

Background and Objectives : Panax ginseng C.A. Meyer is a medical plant that has been widely utilized as a tonic and nutritional agent since ancient times in Korea. Ginseng has anti-metastatic property of cancer and immunomodulating activity. The novel acidic polysaccharide compound(MB40) was isolated from the leaves of Panax ginseng C.A. Meyer. To determine immunomodulating activities of MB40, we evaluate anti-cancer and anti-metastatic effects of MB40 in tumor bearing immune competent mice. Material and Methods : C3H mice were divided into three equal groups(Cisplatin treatment group, MB40 treat-ment group, Cisplatin and MB40 treatment group) and were transplanted SCC(Squamous Cell Carcinoma) cells(2${\times}$106) to the lateral side of abdomen. From day 4 after transplantation, MB40 was administrated at dose of 10mg/kg, respectively, every other day by intratumoral injection. Cisplatin was systemically administrated at doses of 1mg/kg, respectively, every week by intraperitoneal injection. Results : 5 days after administration, tumors can be palpated in every mice group. After 13 days of administration, the mice group to which MB40 were administrated exhibited reduction in tumor size respectively, compared to cisplatin group. Overall status of mice such as body weight and activity were superior in MB40 group than cisplatin group. Conclusion : The result of this study indicates MB40 may have significant therapeutic effect and decreases complications induced by systemic chemotheraphy. MB40 may be developed as a novel and potent immunotropics to improve the cell immune system and anti-cancer drug for the treatment of cancer patients in head and neck squamous cell carcinoma.

In this study we examined the potential for the synergistic augmentation of the activity of inflammatory mouse peritoneal macrophages by stimulation with RGAP combined with IFN-$\gamma$. The moderate augmentative effect induced by preincubation with RGAP was observed in the production of IL-1, IL-6 and NO but not TNF-$\alpha$. In addition, IFN-$\gamma$ had a low activating effect. Following preincubation with both RGAP A and IFN-$\gamma$, a marked enhancement of secretory activity and tumoricidal activity was noted in mouse peritoneal macrophages. Treatment of peritoneal macrophage with combination increased the generation of IL-1, IL-6, TNF-$\alpha$ and NO, whereas the production of reactive oxygen species were not altered. These results demonstrate the synergistic effects on macrophage function of RGAP in combination with IFN-$\gamma$ and suggest that the ability of IFN-$\gamma$ to prime macrophages to produce secretory molecules in response to RGAP may have implications for immunotherapy with this combination.

Ginsan is an acidic polysaccharide purified from Panax ginseng, a famous oriental herb. Although a variety of biological activities of ginsan have been studied, the effects of ginsan on spleen cells are not fully elucidated. We investigated the effect of ginsan on the viability and proliferation of spleen cells. Using Cell Counting $Kit-8^{(R)}$ solution and trypan blue solution, we found that ginsan significantly enhanced viability and proliferation. Multiple clusters, indicating proliferation, were observed in ginsan-treated spleen cells and, carboxyfluorescein succinimidyl ester and surface marker staining assay revealed that ginsan promoted proliferation from $CD19^+$ B cells rather than $CD4^+$ or $CD8^+$ T cells. In addition, ginsan decreased the percentage of late apoptotic cells. Ginsan increased the surface expression of CD25 and CD69 as well as production of interleukin-2 from spleen cells, suggesting increased activation. Taken together, these results demonstrate that ginsan increases the viability and proliferation of spleen cells via multiple mechanisms, valuable information for broadening the use of ginsan in clinical and research settings.

A simple method for the purification of porphyran from laver Porphyra yezoensis was developed to obtain information for the development of food materials with biological functionality. Crude porphyran (CP) was extracted from dried laver in boiling water for 3 h, and then fractionated using cetylpyridinium chloride into an acidic fraction (CP-F1) and a neutral fraction (CP-F2). CP-F1 was fractionated further by fractional ethanol precipitation. Fraction CP-F1-70, precipitated at an ethanol concentration of 61-70% was the major fraction containing 68.1% of the yield from the initial fraction CP-F1. The CP-F1-70 fraction displayed a single band on Sepharose CL-4B with a molecular mass of 550 kDa, indicating a homogeneous polysaccharide. The molar ratio of galactose, 3,6-anhydro-L-galactose, 6-0-methyl-D-galactose and ester sulfate of CP-F1-70 was 1:0.32:0.07:0.53. This method is very useful for rapid and large-scale preparation of purified porphyran because it is compatible with mass production.

A potent immuno-stimulating activity was detected from the watersoluble and ethanol-precipitated crude extract (AG-1) of the root of Angelica gigas Nakai. The crude extract was fractionated into two fractions, an acidic AG-2 and a neutral AG-3 fraction by DEAE-cellulose adsorption. The two fractions contained polysaccharides of which M.W. were 10 Kdal and >2,000 Kdal respectively, proteins, and various inorganic components. The immunostimulating activities of two fractions were not reduced by proteinase K, acid or alkali treatment. The polysaccharides obtained from the root of A. gigas were mainly composed of arabinose, galactose, and galacturonic acid. These results indicated that immuno- stimulating components of the root of A. gigas was a kind of pectic polysaccharides or arabinogalactans.
