Objectives : To investigate the active compounds and therapeutic mechanisms of Atractylodes Lancea(Thunb.) D.C. and Magnolia Officinalis Rehder et Wilson in the treatment of dermatitis accompanied by pruritus, as well as their potential to complement or replace standard drugs. Methods : We conducted the network pharmacological analysis. We selected effective ingredients among the active compounds of research target herbs. Then we explore pathway/terms of the common target proteins among research target herbs, fexofenadine and disease. Results : We selected 9 active compounds are selected from Atractylodes lancea and identified 231 target proteins. Among them, 74 proteins are associated with inflammatory skin diseases that cause pruritus. These proteins are involved in various pathways including, 'Nitric-oxide synthase regulator activity', 'Hydroperoxy icosatetraenoate dehydratase activity, Aromatase activity', 'RNA-directed DNA polymerase activity', 'Arachidonic acid metabolism', 'Peptide hormone processing', 'Chemokine binding' and 'Sterol biosynthetic process'. Additionally, coregenes are involved in 'IL-17 signaling pathway'. Similarly, we selected 2 active compounds from Magnolia officinalis and identified 133 target proteins. Among them, 33 proteins are related to inflammatory skin diseases that cause pruritus. These proteins are primarily involved in 'Vascular associated smooth muscle cell proliferation' and 'Arachidonic acid metabolism'. There is no significant difference between the pathways in which coregenes are involved. Conclusions : It is expected that Atractylodes Lancea will be able to show direct or indirect anti-pruritus and anti-inflammatory effects on skin inflammation accompanied pruritus through suppressing inflammation and protecting skin barrier. Meanwhile, it is expected that Magnolia Officinalis will only be able to show indirect anti-inflammation effects. Therefore, Atractylodes Lancea and fexofenadine are believed to complement each other, whereas Magnolia Officialinalis is expected to provide supplementary support on skin disease.

The crude biopolymer (AS-S1) and endobiopolymer (AS-S2) were isolated from the dry stem bark of Acanthopanax sessiliflorus and tested for anti complement activity. The two potent anticomplement biopolymers, AS-1 and AS-2-Fr.I, were isolated by the combination of ion-exchange chromatography and gel filtration methods from the endo-biopolymers (AS-S2). The anticomplement activity of AS-1 (MW 12 kDa) and AS-2-Fr.I (MW 180 kDa) were found to be 84.4% and 100.0%, respectively, at the concentration of $25{\mu}g/ml$. Activated pathway of the complement system occurred in both classical and alternative pathways, as evidenced by crossed immunoelectrophoresis(CIEP), where a major pathway was detected to be the classical one. It was found that the anticomplement activities of the periodate oxidized were decreased significantly, but those of pronase digested biopolymers of AS-1 and AS-2-Fr.I were decreased very little. The AS-1 contained 2,4,6-tri-O-methyl-D-glucitol, 2,3,6-tri-O-methyl-D-galacitol, and 2,3,6-tri-O-methyl-D-galacitol, which indicated that AS-1 contained a $(1{\rightarrow}3),\;(1{\rightarrow}4)-linked$ glucopyranosyl residue and a $(1{\rightarrow}4)-linked$ galactosyl residue. AS-2-Fr.I contained mainly 2,4-di-O-methyl-D-mannitol and 2,3,4-tri-O-methyl-D-galacitol, which contained $(1{\rightarrow}3),\;(1{\rightarrow}6)$ linked mannosyl and $(1{\rightarrow}6)$ linked galactosyl residues.

To characterize the polysaccharides which exist as soluble forms in Korean traditional alcoholic beverages, the polysaccharides were isolated from Korean pear wine and their anti-complementary activities were examined. The main polysaccharide, PW-1 was purified to homogeneity from the crude polysaccharide (PW-0) in pear wine by size exclusion chromatography using Sephadex G-75. Molecular mass of PW-1 was estimated to be 150 kDa and it contained significant proportion of mannose (81.8%) and 5 different minor component sugars such as arabinose (1.2%), galactose (2.7%), glucose (8.5%), galacturonic acid (5.3%) and glucuronic acid (0.5%). These analyses indicated that the main polysaccharide in pear wine was mainly present as a mannan which had originated from the cell walls of fermenting yeasts. On the other hand, PW-1 showed potent anti-complementary activity in a dose-dependent fashion. Identification of C3 activation products by the crossed immunoelectrophoresis using anti-human C3 and anti-complementary activity of PW-1 in $Ca^{++}$-free condition suggested complement activations by PW-1 from Korean pear wine occur via both classical and alternative pathways.

A complement system-activating (anti-complementary) polysaccharide was purified from the hot water extract of young stems of Cinnamomum cassia Blume. Crude polysaccharide fraction (CC-1) was prepared from the hot water extract of the young stems followed by methanol-reflux, precipitation with ethanol, dialysis, and lyophilization. The anti-complementary activity of CC-1 was decreased greatly by periodate oxidation, but was not changed by pronase digestion. These suggest that carbohydrate moiety may be related to the activation of complement system. According to its ionic strength CC-1 was fractionated first using cetavlon to give 4 fractions, CC-2, 3, 4 and 5. Among them CC-2 fraction was found to retain the highest activity and yield. CC-2 was separated to an unabsorbed neutral sugar portion (CC-2-I) and seven absorbed acidic sugar fractions $(CC-2-II{\rightarrow}CC-2-VIII)$ on DEAE-Toyopearl 650C (Cl-). CC-2-III showing higher anti-complementary activity and yield than those of other fractions, was further purified on the gel permeation of Sephadex G-100 and Sepharose CL-6B to CC-2-IIIa-3. CC-2-IIIa-3 was determined to have a homogeneity hy GPC (Sepharose CL-6B) and HPLC. Gel chromatography using standard dextrans gave a value of $2.4{\times}10^5$ for the molecular weight. The purified polysaccharide, CC-2-IIIa-3 consisted of arabinose, xylose, glucose, galactose, galacturonic acid and glucuronic acid in a molar ratio of 5.56 : 3.77 : 1.87 : 1.00 : 5.12 : 3.13 and contained no nitrogen.

A direct complement fixation test supplemented with procomplementary porcine serum was studied using anticomplementary human, rabbit and bovine serum against Mycobacterium tuberculosis. Procomplementary activity of porcine serum varied with porcine individual and affected by anticomplementary antiserum. The procomplementary titre of porcine serum against rabbit, human and bovine serum ranged from 1:5 to 1:40. By means of complement fixation test supplemented by porcine serum, the specific complement-fixing antibody to both tuberculopolysaccharide and/or tuberculoprotein antigen was readily differentiated from the anticomplementary antibody titre.

To examine the new practical utilization of mucilages in Opuntia humifusa, the Korean pear cactus, the polysaccharides were isolated from O. humifusa, and immuno-stimulating activities were assayed. The main polysaccharide, CNC-E, was prepared by a commercial enzyme treatment, water extraction, and ethanol precipitation. The molecular mass of CNC-E was estimated to be about 700 kDa, and it consisted mainly of arabinose, galactose and xylose in addition to two minor sugars such as rhamnose and fucose. On the other hand, CNC-E showed considerably high splenocyte proliferation activity in a dose-dependent manner. Peritoneal macrophages stimulated with CNC-E produced cytokines such as IL-6, IL-12, IL-10, and TNF-${\alpha}$. The intravenous administration of CNC-E significantly augmented the cytotoxicity of natural killer (NK) cells against Yac-1 tumor cells. Especially, NK cells obtained from the mice treated with $100{\mu}g$ of CNC-E showed threefold higher cytolytic activity than those of untreated mice. CNC-E also showed potent anti-complementary activity in a dose-dependent fashion. Identification of C3 activation products by the crossed immunoelectrophoresis using anti-human C3 and the anti-complementary activity of CNC-E in a $Ca^{2+}$-free condition suggested complement activations by CNC-E that occur via both alternative and classical pathways. These results indicate that Korean pear cactus contains selected polysaccharides that provide immuno-stimulating activities beneficial to human health.

In order to evaluate the potential utilization value as a novel probiotic strain, the immunopotentiating activities of the cellular components from Lactobacillus brevis FSB-1 were examined. L. brevis FSB-1 isolated from kimchi were fractionated into the whole cell, cell wall, cytosol and extracellular preparation, and each fraction was examined on intestinal immune system modulating activity in vitro. The cell wall and cytosol preparation showed the relatively high bone marrow cell proliferating activity through Peyer's patch cell in a dose-dependent manner. But these preparations did not directly stimulate the bone marrow cell proliferation. The whole cell, cell wall and cytosol preparation also induced considerable levels of macrophage activation and mitogenicity of murine splenocytes in vitro. The anti-complementary activity (ITCH_(50)) of the cytosol fraction of L. brevis FSB-1 was the most potent in the cellular components, and the activity showed dose dependency. The complement activation by the cytosol fraction of L. brevis FSB-1 occurs via both alternative and classical pathways, which confirmed by the crossed immunoelectrophoresis using anti-human C3.
