Objectives This study was conducted to confirm the anti-inflammatory effect of Naetakbaekryeom-san (NTB), and whether it could be another treatment for inflammatory diseases. Methods The NTB water extract was extracted with hot water at 100℃ for 2 hours, concentrated at 80℃ under reduced pressure, and used. After 2 hours of pretreatment with NTB and positive control Bay11-7082, nitric oxide (NO), inducible NO synthase (iNOS), interleukin (IL)-6, IL-1𝛽, tumor necrosis factor alpha (TNF-𝛼) were measured in RAW264.7 cells activated with lipopolysaccharides (LPS) 500 ng/mL. After 2 hours of pretreatment with NTB, the anti-inflammatory effect of NTB was evaluated by measuring nuclear factor kappa-light-chain-enhancer of activated B cells (NF-𝜅B) in RAW264.7 cells and 293T cells activated with phorbol 12-myristate 13-acetic acid (PMA) 30 ng/mL. Results In RAW264.7 cells activated with LPS, NTB at concentrations of 0.1, 0.3, and 1.0 mg/mL showed no cytotoxicity, significantly inhibited NO production and inhibition of iNOS expression. TNF-𝛼 cytokine levels was not regulated, but NTB at each concentration inhibited the production of IL-1𝛽 and IL-6, and the effect was higher than that of the positive control Bay11-7082 (20 𝜇M). In PMA-activated RAW264.7 cells and 293T cells, each concentration of NBT decreased the NF-𝜅B transcriptional activity, with the greatest decrease at 1 mg/mL. Conclusions These results demonstrated the anti-inflammatory effect of NTB water extracts, but further studies such as comparison of anti-inflammatory effects and antioxidant effects by NTB component, comparison of effects according to extraction solvents, and clinical studies are needed.

From the perspective of the definition of pain, pain can be divided into emotional and sensory components, which originate from potential and actual tissue damage, respectively. The pharmacologic treatment of the emotional pain component includes antianxiety drugs, antidepressants, and antipsychotics. The anti-anxiety drugs have anti-anxious, sedative, and somnolent effects. The antipsychotics are effective in patients with positive symptoms of psychosis. On the other hand, the sensory pain component can be divided into nociceptive and neuropathic pain. Non-steroidal anti-inflammatory drugs (NSAIDs) and opioids are usually applied for somatic and visceral nociceptive pain, respectively; anticonvulsants and antidepressants are administered for the treatment of neuropathic pain with positive and negative symptoms, respectively. The NSAIDs, which inhibit the cyclo-oxygenase pathway, exhibit anti-inflammatory, antipyretic, and analgesic effects; however, they have a therapeutic ceiling. The adverse reactions (ADRs) of the NSAIDs include gastrointestinal problems, generalized edema, and increased bleeding tendency. The opioids, which bind to the opioid receptors, present an analgesic effect only, without anti-inflammatory, antipyretic, or ceiling effects. The ADRs of the opioids start from itching and nausea/vomiting to cardiovascular and respiratory depression, as well as constipation. The anticonvulsants include carbamazepine, related to sodium channel blockade, and gabapentin and pregabalin, related to calcium blockade. The antidepressants show their analgesic actions mainly through inhibiting the reuptake of serotonin or norepinephrine. Most drugs, except NSAIDs, need an updose titration period. The principle of polypharmacy for analgesia in case of mixed components of pain is increasing therapeutic effects while reducing ADRs, based on the origin of the pain.

Background: Ganoderma lucidum cultured on hulled barley was investigated as a potential natural source of antioxidants and anti-inflammatory agents. Methods and Results: The yields from Ganoderma lucidum cultured on hulled barley water and ethanol extract were 17.69% and 25.77%, respectively. The antioxidant activity of Ganoderma lucidum cultured on hulled barley extracts was confirmed by various methods including assayss of 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2-azino-bis-(3-ethylbenzo thiazoline-6-sulfonic acid) (ABTS), nitrite radical scavenging, and $Fe^{3+}$ to $Fe^{2+}$ reducing power activity. The ethanol extract of Ganoderma lucidum cultured on hulled barley showed improved DPPH, ABTS and nitrite radical scavenging activity compared with the water extract. After treatment of RAW264.7 cells with Ganoderma lucidum cultured on hulled barley ethanol extracts, the cell viability compared with the control was 92.82%, even at a concentration of $3,000{\mu}g/m{\ell}$. The ethanol extract inhibited reactive oxygen species (ROS) generation in RAW264.7 cells stimulated with $H_2O_2$, even at low concentrations. In addition, the ethanol extract showed an inhibitory effects on the production of lipopolysaccharide-induced nitric oxide (NO) in RAW264.7 cells. Conclusions: This study suggests that the extract of Ganoderma lucidum cultured on hulled barley is a potential source of natural antioxidants and anti-inflammatory agents.
This study describes the anti-inflammatory, anti-oxidant, and melanogenesis inhibition activities of methanol extract and various organic solvent fractions of Arecae Pericarpium. We examined the inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 cells, 1,1-diphenyl-2-picrylhydrazine (DPPH) scavenging activity, mushroom tyrosinase inhibition activity and melanin contents. The study showed that, among all tested fractions, methylene chloride fraction showed the strongest inhibition of LPS-induced NO production in RAW 264.7 cells ($IC_{50}$ value $8.89{\mu}g/mL$) and DPPH radical scavenging activity ($EC_{50}$ value $21.39{\mu}g/mL$). Methylene chloride and ethyl acetate fractions similarly inhibited mushroom tyrosinase activity. Methanol extract exhibited strongest reduction of melanin content in B16F10 melanoma cells. Based on the bioactivity assay results, methylene chloride and ethyl acetate fractions were further separated. Eight phenolic compounds were isolated, which are dimeric syringol (1), catechol (2), 4-hydroxybenzaldehyde (3), vanillin (4), 4-hydroxyacetophenone (5), apocynin (6), protocatechuic acid (7) and 4-hydroxybenzoic acid (8). Among the isolated compounds tested, catechol showed the strongest inhibition of LPS-induced NO production in RAW 264.7 cells. Catechol also showed the concentration-dependent NF-${\kappa}B$ inhibition activity. Arecae Pericarpium might have potentials to be developed as anti-inflammatory agent or dermatological product for skin-whitening agent.

This study evaluated the pharmacokinetic profile and therapeutic efficacy of piroxicam (PX), a long acting non-steroidal anti-inflammatory drug for the treatment of arthritis, following intra-articular (IA) injection in comparison to the pharmacokinetic profile and therapeutic efficacy of PX after intramuscular (IM) injection. In the pharmacokinetic study in rats, systemic exposure and pharmacokinetic parameters of PX after a single IA dose were compared with systemic exposure and pharmacokinetic parameters of PX after administration of the same dose IM (0.6 mg/kg). The anti-inflammatory and analgesic effects of IA PX were evaluated simultaneously in a monoiodoacetate-induced osteoarthritis rat model. The plasma PX concentration rapidly rose following IA injection, and it was comparable to the plasma PX concentration following IM injection, suggesting the rapid efflux of the drug molecule from the joint cavity. However, in the efficacy study, the IA PX administration significantly reduced the knee swelling by reducing the level of prostaglandin $E_2$ in the joint, compared to that following administration of IA vehicle and after administration of the IM PX dose. In addition, we found that the anti-inflammatory and anti-nociceptive efficacies of IA PX were synergistically increased upon co-treatment with hyaluronic acid (HA), a potent agent for the treatment of osteoarthritis, at the weight ratio of 1:1 or 1:2, and these effects were more pronounced than those following administration of HA or PX alone. In conclusion, this study demonstrated the efficacy of the IA use of PX alone and/or in combination with HA in osteoarthritis.
Objectives: This study was performed to develop therapeutic prescription that is more significant than existing ones through extraction method and formulation changes. Methods: Yukmijihwangtang(YMJHT) was extracted in 80% ethanol, and their relative anti-oxidant activities as well as anti-inflammatory effects through immune modulation were measured. Results: Both water and ethanol extracted YMJHT showed does-dependent DPPH elimination activities. ROS inhibition activity was greater in water extracted YMJHT except for Moutan Cortex. NO inhibition assay results indicated that all groups showed higher NO inhibition activities in RAW 264.7 cells in dose dependent manner. Water extracted group showed higher NO inhibition activity than that of ethanol extracted group. TNF-${\alpha}$ secretion inhibition assay using RAW 264.7 cells, water extracted YMJHT showed higher activity than ethanol extracts. Growth rate of spleen cells was greater in all tested groups, with higher rate in YMJHT-EtOH than YMJHT-DW. Suppression of gene expression of IFN-r in spleen cells stimulated by Con A was higher in YMJHT-EtOH than YMJHT-DW. Suppression of gene expression of IL-10 in spleen cells stimulated by Con A was highest in YMJHT-DW with 40%. Suppression of gene expression of IL-4 in spleen cells stimulated by Con A were significant with 90% or higher in all groups and that of IL-12p35 were also higher than 90% in all cases. Conclusions: From the results, it shows that YMJHT has anti-inflammatory effects through immune modulation. However, the difference between YMJHT-EtOH and YMJHT-DW was not that significant. Further studies are needed to find out effective extraction methods of herbal medicine.

In this study, the anti-oxidative, anti-inflammatory, anti-melanogenic activities of Endlicheria anomala (Nees) Mez methanol extract (EAME) were evaluated by use of in vitro assays and cell culture model systems. The results revealed that EAME scavenges various radicals such as 1,1-diphenyl-2-picryl hydrazyl hydrogen peroxide induced reactive oxygen species, and lipopolysaccharide induced nitric oxide. Furthermore, EAME induced the expression of anti-oxidative enzymes such as heme oxygenase 1, thioredoxin reductase 1, NAD(P)H dehydrogenase 1, and their upstream transcription factor, nuclear factor-E2-related factor 2. Moreover, EAME inhibited in vitro DOPA oxidation and 3-isobutyl-1-methylxanthine induced melanogenesis in B16F10 cells. Its anti-melanogenic activity will have originated from the inhibition of tyrosinase enzyme activity and melanogenesis related protein expression. Taken together, these results provide the important new insight that E. anomala possesses various biological activities such as anti-oxidative, anti-inflammatory, and anti-melanogenic. Therefore, it might be utilized as a promising material in the fields of nutraceuticals and cosmetics.

In the present study, the substance that show anti-proliferation of cancer cells as well as anti-oxidant and anti-inflammatory effect was searched. As a results, the methanol extract of Pogostemon cablin (P. cablin), is a well-known herb for traditional medicine in Korea and China for treating the digestive disorders, less of appetite, vomiting and diarrhea, inhibited the growth of various cancer cells such as A549, HepG2, MCF7 and HT29 cells. Cytotoxic effect of methanol extraction of P. cablin was excellent in A549 cells. P. cablin extract induced cell cycle arrest at G1 phase of A549 in a dose dependent manner. And it induced phosphorylation of p38 and Cdc25A and reduced expression of Cdc25A, Cdks, Cyclins and phospho-Retinoblastoma (Rb) proteins. Therefore, P. cablin extract seems to act through the p38 - Cdc25A - Cdk - Cyclin - Rb pathway in A549 cells. In addition, P. cablin extract showed anti-oxidant effect by DPPH free radical scavenging assay and anti-inflammation effect by inhibition of lipopolysaccharide (LPS)-induced nitric oxide (NO) in RAW 264.7 cells in a dose-dependent manner. Taken together, these results suggest that P. cablin may be used as not only candidate materials for anti-cancer, anti-inflammatory and anti-oxidant, moreover, it would be possible utilized in various health functional food materials.

In this study, the anti-inflammatory, anti-bacterial and anti-oxidative activities of subcritical water extract from Chamaecyparis obtusa leaves was compared with hot water extract. The yield of subcritical water extract (165℃ and 180℃, 80 bar) was 39.4~48.5%, higher than 31.5% of hot water extract. In the anti-inflammatory tests using lipopolysaccaride (LPS)-induced RAW264.7 macrophages, the subcritical water extract concentration-dependently inhibited production of nitric oxide (NO) without causing cell toxicity. Upon the anti-bacterial studies using Cutibacterium acnes and Staphylococcus epidermidis, subcritical water extract showed the stronger activity than hot water extract. In addition, DPPH and ABTS cation radical scavenging activity experiments showed that the radical scavenging activity of subcritical water extract was similar to that of hot water extract. Moreover, in the study of cell protection effect using HaCaT keratinocytes damaged by hydrogen peroxide (H2O2), the subcritical water extract (165℃, 80 bar) indicated protective effect against oxidative stress. These results suggested that the subcritical water extract of C. obtusa leaves as natural ingredients could be used as anti-inflammatory, anti-bacterial and anti-oxidative ingredients in cosmetic formulations.
Objectives: The aim of this experimental study was to evaluate the anti-neoplastic and anti-inflammatory effects of single and mixed extracts of Ulmus davidiana (UD) and Oldenlandia diffusa (OD) on azoxymethane/dextran sodium sulfate (AOM/DSS)-induced colonic neoplasms in mice. Methods: AOM/DSS induces colitis-associated colonic neoplasms in mice. Mice were divided into seven groups: normal-no inducement and no treatment; control-colonic neoplasms with no treatment; UD-colonic neoplasms and treatment with UD; OD-colonic neoplasms and treatment with OD; UD1+OD1-colonic neoplasms and treatment with UD1 and OD1. UD1+OD2-colonic neoplasms and treatment with UD1 and OD2; UD2+OD1-colonic neoplasms and treatment with UD2 and OD1. Single and mixed preparations of UD and OD were applied to mice for six weeks. The colon length and weight and histopathologic changes of colon tissue were observed. Serum pro-inflammatory cytokines, including tumor necrosis factor-alpha ($TNF-{\alpha}$) and interleukin-6 (IL-6), were determined by enzyme-linked immunosorbent assay. The mRNA expression levels of Bax, Bcl-2, and interferon-gamma ($INF-{\gamma}$) were measured by RT-PCR. Results: The colon length was significantly increased in OD, UD1+OD2, and UD2+OD1 mice, and the colon weight was significantly decreased in OD and UD1+OD2 mice. The morphological change of colon epithelial cells was more suppressed in complex-treatment groups than in single-treatment groups. The inhibitory effect on inflammatory cell invasion was especially shown in UD1+OD2 mice. The serum level of the pro-inflammatory $TNF-{\alpha}$ was decreased in all complex-treatment groups, and the IL-6 level was decreased in UD1+OD1 mice. Single-treatment groups had an increase in the mRNA expression of the pro-apoptosis regulator Bax, and UD2+OD1 decreased the mRNA expression of the anti-apoptosis regulator Bcl-2. The mRNA expression of $INF-{\gamma}$ associated with inflammation was decreased in OD and UD1+OD2 mice. Conclusions: This study suggests that single and mixed extracts of Ulmus davidiana and Oldenlandia diffusa have anti-neoplastic and anti-inflammatory effects on AOM/DSS-induced colonic neoplasms in mice. Therefore, we conclude that UD, OD, and a mixture of UD and OD are potential therapeutic agents for colitis-associated colonic neoplasms.
