Herba Artemisiae Capillaris is the dried bud of Artemisia capillaris Thunb, which has been used for expelling heat to loosen the bowels and normalizing gallbladder function to cure jaundice in traditional oriental medicines. In the present study, we evaluated the anti-inflammatory effects of the aqueous extracts of Herba Artemisiae Capillaris (HAC) in LPS-activated Raw 264.7 cells. Cells were treated with $1\;{\mu}g/ml$ of LPS 1 h before adding HAC extract. Cell viability was determined by MTT assay, and the relative level of NO was measured with Griess reagent. TNF-$\alpha$, IL-$1{\beta}$, and IL-6 cytokines were detected by ELISA. During the entire experimental period, all three doses of HAC extract (0.03, 0.10 and 0.30 mg/ml) had no significant cytotoxicity. LPS-activated cells showed increased NO levels and iNOS expressions compared to control. However, these increases were dramatically attenuated by treatment with HAC extract. Moreover, the inhibitory effects of HAC extract occurred in a dose-dependent manner. In addition, HAC extract reduced the translocation of $NF{\kappa}B$ into nuclear. HAC reduced production of IL-$1{\beta}$ and IL-6 by LPS, although it had no effects on TNF-$\alpha$. These results demonstrate that liquiritigenin exerts anti-inflammatory effects, which results from the inhibition of $NF{\kappa}B$ activation in macrophages, thereby decreasing production of iNOS and proinflammatory cytokines. Taken together, these results indicate that the aqueous extracts of Herba Artemisiae Capillaris warrant further development as an anti-inflammatory agent for the treatment of gram-negative bacterial infections.

This present study was carried out to investigate the biological effects of soybean extracts comparing organic and conventional cultivation. Cellular and molecular analysis was performed to determine anti-oxidative, anti-inflammatory, anti-apoptotic, and anti-inflammatory effects of both soybean extracts. First, we obtained various solvent extracts of soybeans such as water, ethanol, and methanol. Molecular and cellular analysis were performed with 0.1 mg/ml concentration of each solvent extracts. The results of anti-oxidative, anti-inflammatory and anti-apoptotic effects of organic cultivated soybean extracts were prominent than conventional cultivated soybean extracts. However, discrepancy between organic and conventional cultivated soybean extracts was not observed in anti-allergic effects determined by releasing histamine from rat mast cell line, RBL-2H3. Conclusively, organic cultivated soybeans have stronger effects than conventional cultivated soybeans in suppression of inflammation. In addition, organic soybeans could be applied as a functional food ingredient for treatment of chronic inflammation, asthma, and atopic dermatitis with enhanced anti-inflammatory activities.

Coriandrum sativum L., an annual herbaceous plant of Apiaceae family. The present study evaluated the anti-oxidant activities and anti-inflammatory effects of ethanol extracts of C. sativum. The anti-oxidant activities of C. sativum were measured by total contents of polyphenol, flavonoid, DPPH and ABTS radical scavenging and reducing power activity. And anti-inflammatory effects of C. sativum were measured by LPS-induced RAW 264.7 cells. The results showed that the contents of total polyphenol and flavonoid were 76.03 ± 1.36 mg of gallic acid equivalents/g and 182.23 ± 4.32 mg of rutin equivalents/g at concentration 1 mg/mL of C. sativum. The DPPH radical scavenging activity was found to be 52.8% at 500 ㎍/mL. The ABTS radical scavenging activity was shown in 58.3% after exposure to 1,000 ㎍/mL. Reducing power activity was found to be 66.8% at 2,000 ㎍/mL. The inhibitory effect of NO production was found to be 65% concentration 500 ㎍/mL. In the generation quantity of inflammatory cytokines such as TNF-α and IL-1β in cell culture medium, the expression levels of inflammatory proteins in cells were showed decrease with the increase of concentration. Therefore, we suggest that the C. sativum should be a potential source of alternative anti-inflammatory drug with good anti-inflammatory effects.

This study was conducted to investigate the physiological activities and nutrition contents of Gonji No.10 and Solhyang, the strains of Neolentinus lepideus. In nutritional contents of two strains of N. lepideus, the content of free sugars and sugar alcohols and total polyphenol were more in Gonji No.10 than Solhyang. The total contents of amino acids and ${\beta}$-glucan in Solhyang are more than those in Gonji No.10. Solhyang also showed higher DPPH radical scavenging activity than Gonji No.10. In particular, hot water extract of Solhyang has higher inhibitory activity of ${\alpha}$-amylase and ${\alpha}$-amyloglucosidase while Gonji No.10 has higher anti-inflammatiory effect than Solhyang. But, they have similar effects on nitrite scavenging activity.

An one percent sodium carbonate extract prepared from sclerotia of Poria cocos activated the proliferation of the T lymphocytes as measured by mixed lymphocyte responses(MLR). The active fraction, PCSC22, was isolated from an one percent sodium carbonate extract by a combination of fractionation procedures, including ethanol precipitation and chromatographies on column of DEAE-cellulose and Sephadex G50. Carbohydrate and peptide contained in PCSC22 were 78 : 22% in ratio. On employing gel filtration high performance liquid chromatography, PCSC22 exhitited a homogeneous peak with an average molecular weight of 8 kDa. The sugar moiety of PCSC22 was composed with mannose (92%), galactose (6.2%) and arabinose (1.3%), which might be indicated as heteromannan. Fifteen amino acids were found in peptide moiety of the polysaccharide and aspartic acid, serine, and valine were major components. PCSC22 activated the primary proliferation of T lymphocytes measured by mixed lymphocyte responses, the antibody production of the B lymphocytes and the secretion of nitric oxide from macrophage cell line, RAW264.7.

This study was designed to examine the in vitro antioxidant, antimicrobial and anti-inflammation effects of essential oils of Erigeron annuus L. Flower. Erigeron annuus L. essential oils were obtained by solvent extraction. Antioxidative ability was evaluated by bioassays using ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid diammonium salt) radical scavenging effect and 2, 2-diphenyl-1-1-picrydrazyl (DPPH) free radical scavenging activity. Erigeron annuus L. essential oil exhibited free radical scavenging activity on ABTS and DPPH 98.6%, 48.3% respectively, at a concentration of $500{\mu}g/ml$. Antimicrobial activity of essential oils of Erigeron annuus L. were tested against Staphylococcus aureus (S. aureus), Propionibacterium acnes (P. acne) and Escherichia coli (E. coli) by paper disc method, MIC and MBC. Erigeron annuus L. essential oil showed excellent antibacterial activities against S. aureus with MIC and MBC values of 0.31 mg/mL. The clear zone, indicating antimicrobial activity against P. acnes, was 14 mm, MIC and MBC values 0.31 mg/mL, 0.63 mg/mL, respectively. For the anti-inflammatory activity in RAW 264.7 cell, the Erigeron annuus L. essential oils inhibited not only NO production but also the expression of pro-inflammatory cytokines such as, TNF-${\alpha}$, IL-6 in a dose-dependent manner. These results suggested that Erigeron annuus L. essential oils has considerable potential as a cosmetic ingredient with antioxidative, antimicrobial and anti-inflammation effects.

Ellagic acid (EA) is a phenolic compound in fruits and nuts including raspberries, strawberries, grapes and walnuts. Previous studies have indicated that EA possesses antioxidant activity, growth-inhibition and apoptosis-promoting activity in cancer cells. However, macrophage mediated cytotoxicity and immunomodulating effects on cancer cells have not been clarified. In the present study, we show that EA increased effects on macrophage mediated tumoricidal activity and NO production without direct tumor cell cytotoxicity. To further determine whether TLR4 (toll like receptor 4) is involved in anti-tumor activity, cells were treated TLR4 signaling inhibitor, CLI-095 in the presence of EA. CLI-095 treatment partially reduced macrophage-mediated tumoridial activity. EA also has inhibitory effects of NO production induced by LPS, whereas phagocytic activity was not changed. These results suggest that EA induces macrophage mediated tumoricidal activity which is partially related to TLR4 signaling and has a potential adjuvant in cancer therapy.

Aripiprazole (ARI) is a commonly prescribed medication used to treat schizophrenia and bipolar disorder. To date, there have been no studies regarding the molecular pathological and immunotoxicological profiling of aripiprazole. Thus, in the present study, we prepared two different formulas of aripiprazole [Free base crystal of aripiprazole (ARPGCB) and cocrystal of aripiprazole (GCB3004)], and explored their effects on the patterns of survival and apoptosis-regulatory proteins under acute toxicity and cytotoxicity test conditions. Furthermore, we also evaluated the modulatory activity of the different formulations on the immunological responses in macrophages primed by various stimulators such as lipopolysaccharide (LPS), pam3CSK, and poly(I:C) via toll-like receptor 4 (TLR4), TLR2, and TLR3 pathways, respectively. In liver, both ARPGCB and GCB3004 produced similar toxicity profiles. In particular, these two formulas exhibited similar phospho-protein profiling of p65/nuclear factor $(NF)-{\kappa}B$, c-Jun/activator protein (AP)-1, ERK, JNK, p38, caspase 3, and bcl-2 in brain. In contrast, the patterns of these phospho-proteins were variable in other tissues. Moreover, these two formulas did not exhibit any cytotoxicity in C6 glioma cells. Finally, the two formulations at available in vivo concentrations did not block nitric oxide (NO) production from activated macrophage-like RAW264.7 cells stimulated with LPS, pam3CSK, or poly(I:C), nor did they alter the morphological changes of the activated macrophages. Taken together, our present work, as a comparative study of two different formulas of aripiprazole, suggests that these two formulas can be used to achieve similar functional activation of brain proteins related to cell survival and apoptosis and immunotoxicological activities of macrophages.

Objective: This study aimed to evaluate anti-inflammatory and antitussive expectoration effects of Friltillariae Thunbergii Bulbus (FTB) in a mouse model. Materials and Methods: To evaluate the anti-inflammatory effects of the FTB, we conducted in vitro experiments using RAW264.7 cells. An MTT assay and enzyme-linked immunosorbent assay (ELISA) were carried out to examine the anti-inflammatory effects of FTB. The expectorant effect on phenol red secretion, the antitussive effect on cough induced by ammonia solution, and leukocyte increased inhibition effects in acute airway inflammation in the animal model were confirmed. Results: FTB did not show cytotoxicity in the experimental group at 10, 30, 50, 100, 300, or 500 ㎍/ml and significantly inhibited the increase of NO, TNF-α and IL-6 in the experimental groups at 30, 50, 100, 300, and 500 ㎍/ml concentrations. In sputum, cough, and acute airway inflammation animal models, FTB significantly increased phenol red secretion in the 400 mg/kg administration group. FTB significantly reduced the number of coughs and significantly increased cough delay time in both 200 and 400 mg/kg dose groups. FTB decreased the white blood cell count in BALF (bronchoalveolar lavage fluid) in the 400 mg/kg administration group. Conclusion: Our study revealed that FTB elicits antitussive and expectorant effects by inhibiting inflammatory cytokines, increasing sputum secretion, suppressing cough, and reducing inflammatory cells. We concluded that FTB is a highly promising agent for respiratory tract infection with therapeutic opportunities.

This study was perfomed to investigate the effects of Chunghyul-plus(CHP) on oxidative damage and hyperlipidemia in db/db mouse. After treatment with CHP, safety in cytotoxicity, heavy metal toxicity, production of reactive oxygen species(ROS), nitric oxide (N0) and proinflammatory cytokine IL-Ib, TNF-a, IL-6 in RAW 264.7 cells. Serum total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, insulin, GLP-1, glucose, food intake, body weight, organ weight, AST, ALT, ALP, BUN, creatine and histologic change of liver and aorta were measured in db/db mouse after oral administration of CHP. CHP showed safety in cytotoxicity and toxicity of liver and kidney for logn time administration. CHP increased the DPPH and ABTS radical scavenging activity. CHP showed significant inhibitory effect on reactive oxygen species (ROS), and showed inhibitory effect on nitiric oxide(NO) compared to control group. CHP decreased cytokine IL-6 production significantly, and decreased IL-1β and TNF-α compared to control group. CHP decreased body and organ weitht, intake food, and glucose levels compared to control group. CHP decreased total cholesterol and triglyceride significantly, and decreased LDL-cholesterol levels and increased HDL-cholesterol levels compared to control group. CHP decreased atherogenic index and cardiac risk factor significantly. CHP increased serum insulin and GLP-1 compared to control group. In histologic examination, lipophagy in the liver and aorta decreased in CHP treated mice and the cell was regular and boundary of vessel wall was clear compared to control group. These results suggest that CHP is effective in antioxidation activity and treatment and prevention of hyperlipidemia, atherosclerosis, diabetes, ischemic heart disease, stroke and other cardiocerebrovascular disease.
