This study aimed to investigate the beauty food activities of wild-cultivated ginseng (Panax ginseng C.A. Meyer). wild-cultivated ginseng extracts were analyzed for antioxidant, skin whitening, anti-wrinkle effect was measured in water and 70% ethanol extract. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical decolorization activities of water and 70% ethanol extracts were 16.69 and 2.18% as well as 4.04 and 3.25% at a solid content of $200{\mu}g/mL$, respectively. The antioxidant protection factors (PF) of water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$ were 1.06 PF and 1.09 PF, respectively. Thiobarbituric acid reactive substance (TBARs) were both 96% at a solid content of $200{\mu}g/mL$. As PF and TBARs showed higher activity than DPPH and ABTS, we could know that antioxidant activity in the lipophilic component of wood-cultivated ginseng were superior to water-soluble component of wood-cultivated ginseng. Tyrosinase inhibitory activity was 10.97 and 52.39% in water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$. The collagenase and elastase inhibitory activities as anti-wrinkle effect were 15.71 and 20.43% in water extracts as well as 32.26 and 86.74% in 70% ethanol extract at a solid content of $200{\mu}g/mL$. The results show that anti-wrinkle effect was the best among the other experiments. This extracts from wood-cultivated ginseng, therefore, seems to be a potent beauty food resource against wrinkles.

The skin of human is constantly being exposed to environmental irritants such as ultraviolet, smoke and chemicals. These irritants cause free radicals and reactive oxygen species which leave serious damages on the cells of skin. The water and ethanol extracts of Cambodian Phellinus linteus were investigated for the activities of anti-lipid peroxidation and anti-wrinkle effects to apply as a functional ingredient for cosmetic products. As the result of evaluation of liquid oxidation rate by add $Fe^{2+}$ and $Cu^{2+}$ to Cambodian Phellinus linteus extracts, Cambodian Phellinus linteus ethanol extracts were higher than Cambodian Phellinus linteus water extracts in the chealting ability of $Fe^{2+}$ and $Cu^{2+}$. The Cambodian Phellinus linteus ethanol extracts exhibited that anti-lipid peroxidation higher than butylated hydroxytoluene (BHT) at the concentration of 0.1 mg/ml, 0.5 mg/ml and 1 mg/ml. Cambodian Phellinus linteus water and ethanol extracts showed a higher inhibitory effect on $Fe^{2+}$-induced lipid peroxidation compared to $Cu^{2+}$-induced lipid peroxidation. In the case of anti-wrinkle effect, the elastase inhibition activity of Cambodian Phellinus linteus ethanol extracts was 50.7%, and it is higher than urosolic acid at the concentration of 0.01 mg/ml. Also, in collagenase inhibition activity, Cambodian Phellinus linteus water extract showed low effect, but Cambodian Phellinus linteus ethanol extract was about 50% at a 0.1 mg/ml. concentration. These results proved that Cambodian Phellinus linteus had anti-lipid peroxidation and anti-wrinkle effect. Therefore, Cambodian Phellinus linteus could be useful as an anti-wrinkle cosmetic ingredient.

Objectives : The present study was carried out to investigate the effect of Trichosanthis Radix extract (TRE) on the proliferation and activation of eosinophils which were prepared from lung cells of asthma-induced mice by ovalbumin (OVA) treatment. Methods : C57BL/6 mouse was exposed to OVA three times a week for 6 weeks. The mouse lung tissues were dissected out, chopped and dossiciated with collagenase (1 $\mu$g/ml). Eosinophils were activated by rmIL-3/rmIL-5 co-treatments. The lung cells were treated with TRE, incubated for 48 hr at 37$^{\circ}C$, and analyzed by flow cytometer, ELISA and RT-PCR methods Results : To measure cytotoxicity, mouse lung fibroblast cells (mLFCs) were pretreated with various concentrations of TRE. TRE at 100 $\mu$g/ml, the highest concentration, examined did not have any cytotoxic effects on mLFCs. In FACS analysis, number of granulocyte/lymphocyte, CD3e-/CCR3+, CD3e+/CD69+, CD4+/CD8+ T cells in asthma-induced lung cells were significantly decreased by TRE treatment compared to the control group. But CD4+/CD25+ T cells were not examined significant change in lung cells treated with TRE. In ELISA analysis, production levels of IL-3, IL-5, IL-13 and histamine in asthma-induced lung cells, which were induced by rIL-3 plus rmIL-5 co-treatment, were significantly decreased by TRE treatment. Conclusions : The present data suggested that Trichosanthis Radix on the inhibition of parameters associated with asthma responses in eosinpophils, and thus implicate the possibility for the clinical application of Trichosanthis Radix.

In this study, the various physiological and anti-inflammatory activities of Sanguisorba officinalis L. roots (SR) were assessed for potential use as functional cosmetic materials. As a result of measuring electron-donating abilities to determine the antioxidant ability of SR extract, activity increased as the concentration increased, showing an excellent antioxidant capacity of 93.8% at a 1,000 ㎍/ml concentration. Further, the antioxidant power of SR extract, which was determined using an ABTS⁺ assay measurement, was more than 99% at concentrations of 50 ㎍/ml or more, while the tyrosinase inhibition rate was 37.7% at the highest concentration of 1,000 ㎍/ml. Consequently, the elastase and collagenase inhibition of SR extract measured 84.9% and 90.3%, respectively, at a 1,000-㎍/ml concentration. As a result of confirming the survival rate of Raw 264.7 cells, the cell survival rate was determined to be 80% or more below a 100 ㎍/ml concentration, and subsequent cell-related experiments were conducted at concentrations below 100 ㎍/ml. Furthermore, after applying a NO assay to identify anti-inflammatory activity, it was confirmed that SR extract had an inhibitory rate of 50.8% at a concentration of 500 ㎍/ml, and it was excellent at suppressing the inflammatory expression. As a result of verifying protein expression by treating SR extract in Raw 264.7 cells, it was confirmed that expression was inhibited concentrated in all factors. Therefore, it is judged that SR can be used as a functional cosmetic material with antioxidant, whitening, and wrinkle-improving physiological effects and anti-inflammatory activities.

We have compared(using the same series of experimental tissue samples) the levels of proteolytic enzyme activities and free radical-induced protein damage in synovial fluid from RA and CPH cases. Many protease types showed significantly increased (typically by a factor of approximately 2-3-fold) activity in RA, compared to normal rats. However, CPH significantly reduced the cytoplasmic enzyme activities of arginyl aminopeptidase, leucyl aminopeptidase, pyroglutamyl aminopeptidase, tripeptidyl aminopeptidase, and proline endopeptidase to almost about 1/10 each. For the Iysosomal proteases, synovial fluid samples from RA rats, CPH significantly reduced the enzyme activities of cathepsin B, dipeptidyl aminopeptidase I and dipeptidyl aminopeptidase II. In extracellular matrix degrading(collagenase, tissue elastase) and leukocyte as sociated proteases (leukocyte elastase, cathepsin G), CPH decreased these enzyme activities of collagenase, tissue elastase and leukocyte associated elastase in RA. In cytoplasmic and lysosomal protease activities in plasma from RA. CPH and normal plasma samples were not significantly different, suggesting that altered activity of plasma proteases (particularly those enzymes putatively involved in the immune response) is not a contributory factor in the pathogenesis of RA. In addition, the level of free radical induced damage to synovial fluid proteins was approximately twice that in RA, compared with CPH. CPH significantly decreased the level of ROS induced oxidative damage to synovial fluid proteins (quantified as protein carbonyl derivative). Therefore we conclude that both proteolytic enzymes and free radicals are likely to be of equal potential importance as damaging agents in the pathogenesis of inflammatory joint disease, and that the design of novel therapeutic strategies for patients with the latter disorder should include both protease inhibitory and free radical scavenging elements. In addition, the protease inhibitory element should be designed to inhibit the action of a broad range of protease mechanistic types (i.e. cysteine-, metallo- and serine- proteinases and peptidases). However, increased protein damage induced by ROS could not be rationalised in terms of compromised antioxidant total capacity, since the latter was not significantly altered in RA synovial fluid or plasma compared with CPH.

The human skin is constantly exposed to environmental irritants such as ultraviolet, smoke, chemicals. Free radicals and reactive oxygen species (ROS) caused by these environmental facts play critical roles in cellular damage. These irritants are in themselves damaging to the skin structure but they also participate the immensely complex inflammatory reaction. The purpose of this study was to investigate the skin cell protective effect of Juniperus chinensis xylem extract on the UV and SLS-induced skin cell damages. We tested free radical and superoxide scavenging effect in vitro. We found that Juniperus chinensis xylem extracts had potent radical scavenging effect by 98％ at 100 $\mu\textrm{g}$/mL. Fluorometric assays of the proteolytic activities of matrix metalloproteinase-l(MMP-1, collagenase) were performed using fluorescent collagen substrates. UV A induced MMP-1 synthesis and activity were analyzed by enzyme-linked immunosorbent assay (ELISA) and gelatin-based zymography in skin fibroblasts. The extract of Juniperus chinensis showed strong inhibitory effect on MMP-1 activities by 97％ at 100 $\mu\textrm{g}$/mL and suppressed the UVA induced expression of MMP-1 by 79％ at 25 $\mu\textrm{g}$/mL. This extract also showed strong inhibition on MMP-2 activity in UVA irradiated fibroblast by zymography. We also examined anti-inflammatory effects by the determination test of proinflammatory cytokine, interleukin 6 in HaCaT keratinocytes. In this test Juniperus chinensis decreased expression of interleukin 6 about 30％. Expression of prostaglandin E$_2$, (PGE$_2$) after UVB irradiation was measured by competitive enzyme immunoassay (EIA) using PGE$_2$ monoclonal antibody. At the concentrations of 5-50 $\mu\textrm{g}$/mL of the extracts, the production of PGE$_2$ by HaCaT keratinocytes (24 hours after 10 mJ/$\textrm{cm}^2$ UVB irradiation) was significantly inhibited in culture supernatants (p〈0.05). The viability of cultured HaCaT keratinocytes was significantly reduced at the doses of above 10 mJ/$\textrm{cm}^2$ of UVB irradiation, but the presence of these extracts improved cell viability comparing to control after UVB irradiation. We also investigated the protective effect of this extract in sodium lauryl sulfate (SLS)-induced irritant skin reactions from 24 hour exposure. Twice a day application of the extract for reducing local inflammation in human skin was done. Irritant reactions were assessed by various aspects of skin condition, that is, erythema (skin color reflectance) and transepidermal water loss (TEWL). After 5 days the extract was found to reduce SLS-induced skin erythema and improve barrier regeneration when compared to untreated symmetrical test site. In conclusion, our results suggest that Juniperus chinensis can be effectively used for the prevention of UV and SLS-induced adverse skin reactions such as radical production, inflammation and skin cell damage.
