Generally, berry fruits have various pharmacological activities such as anti-inflammation, anti-oxidation and anti-cancer effects. The effects of gooseberry, a berry fruits, on atopic dermatitis (AD) have not been widely examined. The aim of this present study is to investigate whether gooseberry modulates AD. We examined the pharmacological effects of gooseberry on 2, 4-dinitrochlorobenzene (DNCB)-induced AD symptoms in mice. To determine the anti-atopic mechanism of gooseberry, we investigated its effects on the production of inflammatory cytokines and activation of nuclear factor-${\kappa}B$ in PMA + ionophore -stimulated human mast cells (HMC-1). The results demonstrated that gooseberry attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, gooseberry suppressed the expression of inflammatory cytokines and activation of nuclear factor-${\kappa}B$ in stimulated HMC-1. These findings demonstrate that gooseberry is potential agent for treating AD and allergic inflammation.

We attempted to examine anti-inflammatory and anti-oxidant effects of 4'-O-${\beta}$-D-glucosyl-5-O-methylvisamminol (GOMV), the first epigenetic inhibitor of histone phosphorylation at Ser10. While GOMV did not affect the viability of murine macrophage RAW 264.7 cells, it significantly suppressed lipopolysaccharide (LPS)-induced generation of prostaglandin $E_2$ ($PGE_2$) and nitric oxide (NO) through transcriptional inhibition of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). GOMV also scavenged free radicals in vitro, increased NF-E2-related factor 2 (NRF2), and activated antioxidant response element (ARE), thereby resulting in the induction of phase II cytoprotective enzymes in human keratinocyte HaCaT cells. Finally, GOMV significantly protected HaCaT cells against 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced oxidative intracellular damages. Together, our results illustrate that GOMV possesses anti-inflammatory and anti-oxidant activity.

Phytochemical studies were performed to identify the active principles of Phryma leptostachya var. asiatica (Phyrymaceae) for anti-inflammation. The anti-inflammatory activity was assessed by measuring the inhibition rate on nitric oxide (NO) formation in lipopolysaccharide (LPS)-activated macrophage 264.7 cells. Of the five compounds including ursolic acid, phrymarolin I, harpagide, haedoxancoside A, and acteoside isolated from this plant, ursolic acid showed the most prominent inhibition of NO formation. Therefore, ursolic acid may be the anti-inflammatory principle of Phryma leptostachya var. asiatica.

Protulaca oleracea, a widely distributed weed, has been reported to exhibit different health promoting effects. The objective of this study was to evaluate the anti-oxidative and anti-inflammatory effects of P. oleracea on LPS-stimulated AGS cells. The cytotoxicity of P. oleracea in AGS cells was examined by MTT assay. The anti-oxidative effects of P. oleracea were examined by DPPH assay. RT-PCR was carried out to examine the effect of P. oleracea in the mRNA expression of different inflammatory mediators. MTT assay revealed that P. oleracea have almost no cytotoxity in AGS cells. DPPH radical scavenging activities were better than butylated hydroxyl toluene (BHT). The mRNA expression of different endogenous anti-oxidative enzymes (SOD2, GPx3 and catalase) were preserved by P. oleracea in AGS cells. The nitric oxide production and expression of iNOS in LPS stimulated RAW264.7 were suppressed in P. oleracea treated groups. Based on these findings, P. oleracea has protective anti-oxidant and anti-inflammatory effects.

Acne vulgaris, the most common skin disease. can be formed as only a few comedons or severe inflammatory lesions. The pathogenesis of acne involves various factors; excessive androgen, excessive sebum production, abnormal alteration of follicular epithelium, proliferation of Propionibacterium acnes, and inflammation. We investigated acne therapy using oriental herbs described in the Korean traditional medical book(Dong-ui-bo-gam). Oriental herbs(Angelica daurica, Arctium lappa, Coptidis rhizoma, and Glycyrrhiza glabra) were chosen based on their respective property of sebum control, anti-inflammatory activity, and anti-bacterial activity. We examined the effect of acne treatment, in terms of chemotactic inhibition, lipogenesis inhibition, and anti-bacterial activity for P. acnes. 1. Neutrophil chemotaxis assay; P. acnes secrete chemotactic factors and other pro-inflammatory extracellular products. Neutrophil chemotactic activity of P. acnes was measured by 48-well chemotaxis method. Angelica daurica clearly suppressed chemotactic activity of P. acnes. 2. Using sebaceous gland of hamster ear lipogenesis assay; Sebaceous lipogenesis was measured using ear biopsies by incubation or $C^{14}$-acetate in culture media. The $C^{14}$-labeled lipids were extracted and determined by liquid scintilation counting. Coptidis rhizoma markedly inhibited sebum production. 3. Anti-bacterial assay for P. acnes(MIC test); Glycyrrhiza glabra showed anti-bacterial activity. P. acnes did not develop resistance against Glycyrrhiza glabra. Retinoids are effectively to inhibit sebum production and regulate follicular keratinization process, with little anti-inflammatory activity. Angelica daurica suppressed neutrophil chemotaxis, Coptidis rhizoma inhibited sebum production, and Glycyrrhiza glabra showed anti-bacterial activity against P. acnes. A combined formulation of Angelica daurica, Coptidis rhizoma. and Glycyrrhiza glabra is expected to provide effective acne treatment.

This study was designed to elucidate the anti-inflammatory, cardiovascular, anti-thrombotic, and analgesic effect of Whalrakdan. The anti-inflammatory effects was measured by the method of carrageenin induced edema, protein leakage test using CMC-pouch, and the effect of Whalrakdan on the cardiovascular system was observed by the change of flow rate of Ringer solution in the vascular system in the ear of rabbit. and the contraction and dilatation of rat tail artery. Death rate, platelet aggregation, plasma coagulation activity, antithrombin activity was observed for the measurement of the anti-thrombotic effect of Whalrakdan, and the analgesic effect was measured by the acetic acid method and hot plate method. The result was as follows: 1. After 2 or 3hour of Whalrakdan administration, carrageenin induced edema and CMC-pouch protein leakage was significantly decreased. 2. The slight anagesic effect of Whalrakdan extract was confirmed by the observation of writhing syndrome, paw licking time, and escape time. 3. The droplet of Ringer solution increased according to the increase of concentration of Whalrakdan extract, and the vasoconstriction decreased dependantly to the concentration of Whalrakdan extract. 4. The anti-thrombotic effect of Whalrakdan was observed by the decrease of death rate, the inhibition of platelet aggregation, and the increase of anti-thrombin activity.

This study was performed to investigate the effects of treatment for dermatitis using the herbal gel preparations. Scutellariae Radix(SR) and Zingiberis Rhizoma(ZR) were used for the purpose of herbal preparations. Baicalin, baicalein are the ingredients of SR, having biological effects like anti-inflammatory, anti-oxidative, anti-bacterial and antiallergic action. 6-Gingerol is one of the ingredients of ZR having biologicai effects like anti-inflammatory and analgesic action. The three types of hydrogels(SRE, SRH, SZH) were formulated with Carbopol 940, Labrasol, Triethanolamine etc. Baicalin was hydrolysed to baicalein by $\beta$-glucuronidase for the purpose to increase rate of skin permeation. Content of ingredients by HPLC determination, rate of skin permeation using Franz type diffusion cell, anti-oxidative activity for the free radical, hydroxyl radical, superoxide, anti-inflammatory by using carrageenan injection, efficacy on the dermatitis induced by 2,4-dinitro-chlorobenzene(DNCB) were experimented. Baicalein showed higher permeability than baicalin, so it is considered that baicalein was more suitable form than baicalin for transdermal absorption by its lipophilic property. In the anti-oxidative experiments, SZH gel was the most effective scavenging activity than the other gels in all experiments. In anti-inflammatory test, SRM and SZH gel more decreased edma rapidly than SRE gel. In case of using SZH gel, treatment period for the dermatitis was more declined than that of other gel groups. These results suggests that the SZH hydrogel could be suitable preparations for the treatment of dermatitis.

We recently demonstrated that bee venom (BV) injection into acupoint (i.e. Zusanli) produced more potent anti-inflammatory and antinociciptive effect in Freunds adjuvant induced rheumatoid arthritis (RA) model as compared with that of non-acupoint injection(i.e back). However, the precise components underlying BV-induced antinociceptive and/or anti-inflammatory effects have not been fully understood. Therefore, we further investigated the anti-arthritic effect of BV after extracting the whole BV according to solubility (water soluble: BVA, ethylacetate soluble: BVE). Subcutaneous BVA treatment (0.9 mg/kg/day) into Zusanli acupoint was found to dramatically inhibit paw edema and radiological change (i.e. new bone proliferation and soft tissue swelling) caused by Freunds adjuvant injection. In addition, the increase of serum interleukin-6 by RA induction was normalized by the BVA treatment as similar with that of non-arthritic animals. On the other hand, BVA therapy significantly reduced arthritis induced nociceptive behaviors (i.e., nociceptive score for mechanical hyperalgesia and thermal hyperalgesia). Furthermore, BVA treatment significantly suppressed adjuvant induced Fos expression in the lumbar spinal cord at 3 weeks post-adjuvant injection. However, BVE treatment (0.05 mg/kg/day) has not any anti-inflammatory and anti-nociceptive effect on RA. Based on the present results, we demonstrated that BVA might be a effective fraction in whole BV for long-term treatment of RA-induced pain and inflammation. However, it is clear necessary that further fraction study about BVA was required for elucidating an effective component of BVA.

To investigate the natural cosmetic ingredients of Benincasa hispida seed extract on skin care, we measured anti-oxidant and anti-inflammatory, and whitening effect. DPPH free radical scavenging activity was increased in a dose-dependent manner. The total phenolic content was higher in methanol extract (22.42±0.002 mgGAE/g) than water extract (9.77±0.002 mgGAE/g). MTT assay was demonstrated that the seed extract did not have a cytotoxic effect in RAW264.7 and B16F10 cell lines. We also examined to find out the inhibitory activity on NO production and secretion of TNF-α cytokine in LPS-induced RAW264.7 cells. In B16F10 melanoma cells, the seed extract significantly suppressed α-MSH induced melanin synthesis. Furthermore, westernblot analysis revealed that methanol extract dramatically downregulated the expression level of MITF, TRP-1 and TRP-2. Taken together, the B. hispida seed extract posses anti-oxidant, anti-inflammatory and skin whitening activities, which might provided its functional efficacy in cosmetic materials.
