Acanthopanax sessiliflorus (A. sessiliflorus) has been known as a traditional medicine having anti-stress, antioxidative and platelet aggregation inhibitory effects. This study was undertaken to investigate the functional properties of water extracts from four parts of A. sessiliflorus. Root, stem, leaf and fruit extracts from A. sessiliflorus were prepared with hot water ($80^{\circ}C$). The contents of functional substances, eleutheroside B and E, polyphenol, antioxidative activity, nitrite scavenging ability and anti-cancer activity of the extracts were determined. The contents of eleutheroside E in stem, root and fruit extracts were 542.50 ${\mu}$g/g, 343.35 ${\mu}$g/g and 30.78 ${\mu}$g/g, respectively. A large part of eleutheroside B was found in fruit (372.01 ${\mu}$g/g) and root (289.33 ${\mu}$g/g) extracts. Root and stem extracts contained 227.21 mg/100g and 131.22 mg/100g of polyphenols, respectively. Antioxidative activities (electron donating ability) of stem and root extracts were 79.87% and 77.27%, respectively. It appears that the antioxidative activities were related to polyphenol contents of the extracts. Most extracts showed 76-81.5% of nitrite scavenging ability at pH 1.2. It reveals that water extract from parts of A. sessiliflorus can inhibit formation of nitrosoamine in food. Effects of the extracts on the growth of normal and cancer cell lines were investigated. Extracts showed no cytotoxicity to normal dendritic cell line (DC2.4). Especially, the root extract promoted the growth of normal cell line. Root and stem extracts had 20-23% of inhibitory effect against stomach cancer cell line (SNU-719) and liver cancer cell line (Hep3B). These result indicated that the extracts from A. sessiliflorus can be used as functional food materials with antioxidative activity and nitrite scavenging ability to eliminate nitrosoamine in food.

Osteoporotic fracture became a serious social problem, which related with mortality and morbidity in old age population. Osteoclast which is responsible for bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Cynanchum wilfordii (Asclepiadaceae) roots have been used in Korean folk medicine for the treatment of diabetes mellitus and aging progression. Also, recent studies have shown that the extract and fractions of Cynanchi Wilfordii Radix have various pharmacological actions including scavenging free radicals, enhancing immunity, reducing high serum cholesterol, and anti-tumor activity. However, the effect of extract of Cynanchi Wilfordii Radix in osteoclast differentiation had not been reported. Thus, we evaluated the effect of Cynanchi Wilfordii Radix on receptor activator of nuclear factor-${\kappa}B$ ligand (RANKL)-induced osteoclast differentiation. Through our study, we found that Cynanchi Wilfordii Radix significantly inhibited osteoclast differentiation induced by RANKL. Cynanchi Wilfordii Radix suppressed the activation of p38 pathway and $NF{\kappa}B$ in bone marrow macrophages (BMMs) treated with RANKL. Also, Cynanchi Wilfordii Radix significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Cynanchi Wilfordii Radix inhibited the protein expression of c-fos and NFATc1. Taken together, our results demonstrated that Cynanchi Wilfordii Radix may be useful treatment option of bone-related disease such as osteoporosis leads to fracture of bone and rheumatoid arthritis.

Assessment was made of the effects of Aralia cordata Thunb (DH) on the cell proliferation, inducible nitric oxide synthase (iNOS) mRNA gene expression and nitric oxide (NO) production in RAW 264.7 macrophage cells. For the screening of anti-inflammatory activities, ethanolic extracts of 55 species of traditional herbal medicines were examined for inhibitory effects, and it was confirmed that DH possessed inhibitory effects on NO production. As a result, DH significantly decreased the production of NO and iNOS gene expression at a concentration of $250{\mu}g/mL$. The chloroformsoluble fractionates have the strongest No synthesis inhibitory effect. It is presumed that the inhibition of NO production in LPS-stimulated RAW 264.7 cells by DH components occurred via the modulation of iNOS and DH, and that the active compound from DH may be useful for therapeutic management of inflammatory-associate diseases.

Purple bamboo salt (PuBS) is commonly used as a medicinal food in Korea and has beneficial potentials such as antioxidant and anti-inflammatory effects. Rubus coreanus is called Bokbunja, which is used as a traditional medicine for treating asthma, impotence, and allergic diseases in Korea. The aim of present study was to investigate the immunostimulatory effect of PuBS composed with Rubus coreanus (PuBS-R). We performed comparative analysis between PuBS and PuBS-R in Raw264.7 cells, which is a mouse macrophage cell line, and peritoneal macrophages isolated primarily from the mouse peritoneal cavity. We evaluated cytotoxicity and the immune cytokine response in PuBS- and PuBS-R-treated cells. Both PuBS and PuBS-R did not have any cytotoxicity in Raw264.7 cells up to $500{\mu}g/mL$. Gene and protein levels of immune cytokines such as tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), $interferon-{\gamma}$ ($IFN-{\gamma}$), interleukin (IL)-10, and IL-12 were significantly elevated by PuBS-R more than PuBS in Raw264.7 cells. Moreover, we evaluated the immunostimulatory effects of PuBS-R on mouse primary peritoneal macrophages. Protein levels of inducible nitric oxide synthase, $TNF-{\alpha}$, $IFN-{\gamma}$, IL-10, and IL-12 were significantly higher in PuBS-R-treated peritoneal macrophages than PuBS-treated peritoneal macrophages. These results suggest the potential immunostimulatory effect of PuBS-R for immunity against harmful infection.

Cordyceps militaris has been used in traditional Chinese medicine owing to its anticancer and immunomodulatory activities. Germanium compounds have also been shown to be associated with many pharmacological functions, such as antimicrobial, antiviral, antitumor, antimutagenic, and immunomodulating effects. In this study, we examined the biological properties of hot water extract from mycelial liquid culture of germanium-enriched C. militaris (CMGe). CMGe displayed a concentration-dependent antiproliferation activity against four human cancer cell lines. The antiproliferative activity of CMGe was 2-4-fold lower than that of hot water extract from mycelial liquid culture in C. militaris (CM). However, CM had a concentration-dependent cytotoxicity to human bone marrow-derived mesenchymal stem cells (MSCs). Contrastingly, CMGe did not cause any cellular damage to MSCs. MSCs cultured with CMGe displayed an increased proliferative activity with no cytotoxic effect. The oral administration of CMGe inhibited increased tumor volume and weight compared with the control group. CMGe has the potential to be used as an industrial product in medicinal foods as well as in pharmaceutical products.

α-Asarone is the main component of Acorus gramineus, which is a widely used oriental traditional medicine. A. gramineus is known to have a variety of medicinal effects, such as anti-gastric ulcer, antiallergy and antioxidant activity. It is also known to inhibit the release of histamine. However, the mechanism of its action remains unclear in humans. In this study, the effects of α-asarone on matrix metalloproteinase (MMP) and its antioxidant effect in a cell-free system were examined in HT1080 cells. In an MTT assay, the effect of α-asarone on cell viability showed no cytotoxicity below 16 μM. In an antioxidant assay, α-asarone increased reducing power in a dose-dependent manner but not the scavenging activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. In addition, α-asarone exhibited the protective effect against DNA oxidation induced by hydroxyl radicals produced by the Fenton reaction. Furthermore, in a gelatin disk assay, α-asarone enhanced collagenase activity. It also increased the activities of MMP-2 and MMP-9 stimulated by phorbol 12-myristate 13-acetate (PMA) in a gelatin zymography. On the other hand, the activity of MMP-9 stimulated by phenazine methosulfate (PMS) but not that of MMP-2 was increased in the presence of α-asarone. These findings suggest that α-asarone could be a candidate for the prevention and treatment of pathological diseases related to oxidative stress and MMPs.

Melanogenesis is involved in the pigmentation of the hair, eyes, and skin in living organisms. Various signaling pathways stimulated by ${\alpha}-MSH$, SCF/c-Kit, $Wnt/{\beta}-catenin$, nitric oxide and ultraviolet activate melanocyte, leading to melanin production by tyrosinase, tyrosinase-related protein (TRP)-1, and TRP-2 expressed via the microphthalmia-associated transcription factor (MITF). However, the abnormal regulation of melanogenesis causes dermatological issues such as graying hair and vitiligo. Therefore, the activators that promote melanogenesis are crucial for the prevention of graying hair and the treatment of hypopigmentary disorders. Many melanogenesis stimulators have been studied for the development of novel drugs derived from synthesized compounds and natural products. Here, in addition to providing a description of a common signaling pathway in the melanogenesis of graying hair and the vitiligo process for the development of novel anti-hair graying agents, this article reviews natural herbs and the active ingredients that promote melanin synthesis as a pharmaceutical agent for the treatment of vitiligo. In particular, compounds such as Imatinib and Sugen with a stimulating effect on melanogenesis as a side effect of the drugs, are also introduced. Recent advances in research on natural plant extracts such as Polygonum multiflorum, Rhynchosia Nulubilis, Black oryzasativa, and Orysa sartiva, widely known as traditional and medicinal extracts, are also reviewed.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease. characterized by leukocyte infiltration, a chronic inflammation of the joint, a pannus formation and the extensive destruction of the 3Iticular caJ1ilage and bone. Several proinflammatory cytokines such as tumor necrosis factor-${\alpa}$(TNF-${\alpa}$), interleukin-1${\beta}$ (IL-1${\beta}$) and interleukin 6 (IL-6) have been implicated in the pathological mechanisms of synovial tissue proliferation, joint destruction and programmed cell death in rheumatoid joint. In the Korean traditional medicine, Hominis placenta (HP) as an herbal solution of herb-acupuncture has been widely used to treat the inflammatory diseases including RA. In order to study the medicinal effect of HP herb-acupuncture on rheumatoid joint, an adjuvant-induced arthritis (AlA) was generated by the injection of 1.5 mg uf Mycobactelium tuberculusis. emulsified in squalene, 10 the base of the tail of Sprague-Dawley(SD) rats. After onset stage of polyarthritis, HP was daily injected to the Zusanti (ST36) acupuncture points in both of rat lags and the expression pattems of cytokines such as TNF-{\alpa}$, IL-1${\beta}$, and 1L-6 at the knee joint were analyzed using immunostaining and RT-PCR. The HP herb-acupuncture was found to be effective to alleviate the arthritic symptums in adjuvant-induced arthritic rats as regards the joint appearance and the expression profiles of inflammatory cytokines. In conclusion, therapeutic effects of HP herb-acupuncture on the rat with AlA might be related to anti inflammatory activities of the hurb-acupuncture.

The Korean traditional medicine, Seonghyangjeonggisan (SHJGS) has long been used for acute cerebral infarction (Cl). However, scientific investigation has been carried out a little. Cytokines, involved in the regulation of inflammatory reactions and immune responses, may play an important role in the pathogenesis of Cl. The aim of this study is to investigate the effects of SHJGS on the production of various cytokines in the patients with acute Cl. Peripheral blood mononuclear cells (PBMC) obtained from the patients with acute Cl were cultured for 24hr in the presence or absence of lipopolysaccharide (LPS) and phytohaemagglutinin (PHA). The amount of TNF-α, IL-1β, IL-6 and IL-8, in PBMC culture supernatant, was significantly increased in the LPS and PHA treated cells, compared with unstimulated cells (P<0.05). This study showed that increased TNF-α, IL-1β, IL-6 and IL-8 level stimulated by LPS and PHA was inhibited by SHJGS (0.01-1 ㎎/㎖) in a dose-dependent manner but IL-8 level was not inhibited significantly at 1㎎/㎖ (P>0.05). The maximal inhibition rate of TNF-α, IL-1β, IL-6 and IL-8 by SHJGS (1㎎/㎖) was 68% (P<0.05), 53.9% (P<0.05), 45.5% (P<0.05), 46.7% (P>0.05) respectively. These results suggest that SHJGS might have anti-inflammatory effects through cytokine modulation. which might explain its beneficial effects in the treatment of acute Cl.
