Oryeong-san (ORS) is a traditional Korean herbal medicine widely used for renal associated diseases, composed of five medicine herbs; Atractylodes japonica Koidzumi, Cinnamomum cassia Presl, Polyporus umbellatus Fries, Poria cocos Wolf and Alisma orientale Juzepzuk. We studied to improve the convenience of intake and portability by developing modernized dosage forms, and examined the effect on anti-inflammation of ORS. In order to develop the tablet formulation of ORS (ORS-F), the tablets were evaluated on the basis of physical characteristics include diameter, thickness, weight variation, hardness, friability and disintegration. To analyze the marker components of ORS-F, eight index markers from five herbal medicines were chosen. And the method using high performance liquid chromatography (HPLC) with diode-array detector method was established for the simultaneous analysis. The biological activities were examined the effect of ORS-F on pro-inflammation mediated by LPS-stimulation. The production of nitric oxide (NO) and cytokines were determined by reacting cultured medium with griess reagent and enzyme-linked immunosorbent assay (ELISA). The expression of cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS) were investigated by Western blot and RT-PCR. The anti-oxidant activities of OJS-F increased markedly, in a dose-dependent manner. and, The total phenolic compound and flavonoids contents of OJS-F were 10.20±0.09 ㎍/㎎ and 12.86±0.86 ㎍/㎎. OJS-F which is LPS has diminished in the LPS-induced release of inflammatory mediators (NO, iNOS, COX2 and PGE2) and pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β) from the RAW264.7 macrophages. Therefore, the developed formulation for tablet of ORS-F provide efficiency and usability, and indicated effect of anti-inflammation.

Objective: The objective of our study was to investigate anti-cancer effects of Danggui Liuhuang Decoction extract bioconverted by protease liquid coenzyme of Aspergillus kawachii (DLD-BE), compared to a non-bioconverted DLD extract (DLD-E) and determine the underlying mechanisms. Methods: DLD-E and DLD-BE were evaluated for their ability to modulate these signaling pathways and suppress the proliferation of human colorectal cancer (CRC) cells, HCT-116, LoVo, and HT-29. The anti-cancer effects of DLD-E and DLD-BE were measured by using proliferation and migration assays, cell cycle analysis, Western blots, and real-time PCR. Results: In this study, treatment with DLD-E and DLD-BE at concentrations of 25-100 ㎍/mL inhibited proliferation and migration in human CRC cells. DLD-BE induced apoptotic cell death and decreased COX-2 expression in HT-29 cells. The mechanisms of action included modulation of the AKT and extracellular-signal-regulated kinase signaling cascades along with inhibition of COX-2 expression. The results demonstrate novel anti-cancer mechanisms of DLD-BE against the growth of human CRC cells. Thus, we propose that DLD-BE can be developed as a more potent supplement to inhibit colorectal tumor growth and intestinal inflammation than DLD-E.

In this study, the antioxidant, anti-xanthine oxidase, anti-melanogenic and anti-wrinkle effects of methanol (ME) and hot water (HE) extracts from the fruiting bodies of Phellinus vaninii were investigated. The 1,1-diphenyl-2-picryl-hydrazyl free radical scavenging activity of 2.0 mg/mL HE (95.38%) was comparable to that of butylated hydroxytoluene (96.97%), the reference standard. The hydroxyl radical scavenging activities of ME (98.19%) and HE (97.55%) were higher than that of butylated hydroxytoluene (92.66%) at 2.0 mg/mL. Neither ME nor HE was cytotoxic to murine melanoma B16-F10 cells at 25-750 ㎍/mL. Although the xanthine oxidase (XO) inhibitory effects of ME and HE were significantly lower than that of allopurinol, the values were higher than 84 percent. The in vitro tyrosinase inhibitory activities of ME and HE were comparable to kojic acid at 2.0 mg/mL. The cellular tyrosinase and melanin synthetic activities of ME and HE on B16-F10 melanoma cells at 500 ㎍/mL were higher than arbutin, indicating that the inhibitory effects of arbutin on the tyrosinase and melanin synthesis were higher than those of ME and HE. The collagenase inhibitory activity of HE was comparable to EGCG at 2.0 mg/mL, however, the elastase inhibitory activity of ME and HE was lower than EGCG at the concentration tested. The study results demonstrated that the fruiting bodies of Ph. vaninii possessed good antioxidant, anti-xanthine oxidase, cell-free anti-tyrosinase, cellular anti-tyrosinase, anti-collagenase, and moderate anti-elastase activities, which might be used for the development of novel anti-gout, skin-whitening, and skin anti-wrinkle agents.

Black ginseng is produced by a repeated steaming process. The aim of this study was to investigate the anti-obesity effects of black ginseng ethanol extract (BG-EE) in high fat (HF) diet-fed mice. Two groups were fed either a normal control (NC) diet or a HF diet (45% kcal fat). The other three groups were given a HF diet supplemented with 1% BG-EE, 3% BG-EE, and 5% BG-EE for 12 wk. The anti-obesity effects of the BG-EE supplement on body weight, the development of fat mass, and lipid mechanisms were assessed in obese mice. HF-induced hyperlipidemia, fat accumulation in the liver, and white adipose tissues were reduced after BG-EE supplementation. Total fecal weight and the amount of fecal fat excretion also were increased after BG-EE supplementation. These results suggest that BG-EE may be useful to ameliorate HF-induced obesity through the strong inhibition of fat digestion.

This study was performed to examine the anti-metastatic effect of ethanol extract of Samguikoeui-Tang (SGKE), a formula consisting of four oriental herbs, in highly-metastatic HT1080 human fibrosarcoma cells. SGKE significantly inhibited the adhesion of HT1080 cells to matrigel at nontoxic concentrations in a dose-dependent manner, while it did not exert cytotoxicity against HT1080 cells up to the concentration of 100 ${\mu}g$/ml. Also, SGKE depressed the activity of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) by gelatin zymography. However, SGKE did not affect the mRNA expression of MMP-2 and TIMP-2, an inhibitor of MMP-2, by RT-PCR analysis. In addition, the effect of SGKE on HT1080 cell invasion was determined using Boyden chamber assay. SGKE suppressed the invasion of HT1080 cells in a dose-dependent manner. Taken together, these results suggest that SGKE has an anti-metastatic effect via inhibition of MMP-2 and -9 activities.

Dandelions have been reported to have medicinal properties and bioactive components that impact human health. However, the precise biological properties of dandelions and the parts of the plants possessing bioactive components remain uncertain. In this study, we evaluated 3 different types of dandelions based on their cultivation origin (Songpa, Uiryung, and native Uiryung types) as well as their 4 different plant parts (leaf, flower, root, skin). Each sample was extracted with $80\%$ methanol and then compared for the biological activities (anti-oxidative, immune cell proliferative and tumor cell growth inhibitory activities). All 3 types of dandelions possessed a degree of biological functions including the hydroxyl radical scavenger activity, immune cell proliferative activity and tumor cell growth inhibitory activity. However, there was no significant difference in these activities between the 3 dandelion types. Leaves of all three dandelion types showed the highest levels of all biological activities. To a lesser degree, the flower and root parts displayed biological activities. In the skin parts, anti-oxidative activity was also detected only at higher doses of dandelion extracts. Heating the dandelion leaf extract did not affect the biological activity, suggesting a heat-stable nature of the biological compounds. Taken together, these collective data suggest that dandelions, in particular their leaves, possess a high concentration of heat-resistant biological compounds, which are responsible for anti-oxidative, immune cell proliferative and tumor cell growth-inhibitory activities.

Probiotics are known to provide the host with immune-modulatory effects and are therefore of remarkable interest for therapeutic and prophylactic applications against various disorders, including inflammatory diseases. Weissella cibaria JW15 (JW15) has been reported to possess probiotic and antioxidant properties. However, the effect of JW15 on inflammatory responses has not yet been reported. Therefore, the objective of the current study was to evaluate the anti-inflammatory potential of JW15 against lipopolysaccharide (LPS) stimulation. The production of pro-inflammatory factors and the cellular signaling pathways following treatment with heat-killed JW15 was examined in LPS-induced RAW 264.7 cells. Treatment with heat-killed JW15 decreased nitric oxide and prostaglandin $E_2$ production via down-regulation of the inducible nitric oxide synthase and cyclooxygenase-2. In addition, treatment with heat-killed JW15 suppressed the expression of pro-inflammatory cytokines, interleukin $(IL)-1{\beta}$, IL-6, and tumor necrosis factor-${\alpha}$. The anti-inflammatory properties of treating with heat-killed JW15 were associated with mitogen-activated protein kinase signaling pathway-mediated suppression of nuclear factor-${\kappa}B$. These results indicated that JW15 possesses anti-inflammatory potential and provide a molecular basis regarding the development of functional probiotic products.

Objectives: The aim of this study is to investigate the anti-inflammatory effects of Ojeok-san and compare the therapeutic effects according to its formation. Methods: We evaluated the anti-inflammatory effects of Ojeok-san using lipopolysaccharide (LPS) induced inflammatory animal model. Male SD rats were administered intra-orally with two different formulation types of Ojeok-san according to prescribed dosage. One hour later, to induce inflammatory responses, subsequent intra-peritoneal injection of LPS was conducted. After 5 hours later, serum TNF-α, IL-1β, IL-6 and PGE2 levels were measured by ELISA to assess the alteration of pro-inflammatory markers. Results: In our experiment, regardless of its formation, administration of Ojeok-san decreased TNF-𝛼, IL-1𝛽, IL-6 and PGE2 level in serum. Furthermore, LPS-induced toxicity of liver and kidney was not detected by Ojeok-san administration. Conclusions: The anti-inflammatory effect of Ojeok-san was shown in LPS-induced inflammatory model by decreasing pro-inflammatory markers, and there would be no significant difference in therapeutic effect between two formulation types of Ojeok-san.
