In this study Anti-inflammatory activity was investigated for the extract of Prunus pendula for. ascendens (Makino) Ohwi by monitoring nitric oxide (NO) production in LPS-stimulated RAW 264.7 murine macrophage cells. The P. pendula ethyl acetate (EtOAc) fraction showed to decrease the NO synthesis by 76.3% at $100{\mu}g/mL$ concentration. The inhibition occurred in a dose-dependent manner without causing cell toxicity. The EtOAc fraction also inhibited the production of $PGE_2$, $IL-1{\beta}$, IL-6 and expression of iNOS, COX-2 protein in dose-dependent manner. From the phytochemical study to isolate the active constituents, five known compounds were identified, which are ursolic acid (1), prunasin (2), methyl p-coumarate (3), kaempferol (4), astragalin (5). All of the compounds 1 - 5 were isolated for the first time from the P. pendula. Among the isolates, the flavonoids 4 and 5 were verified to inhibit NO production with high efficiency. These results suggested that extract of P. pendula leaves could be useful as anti-inflammatory agents in pharmaceutical or cosmetic applications.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.

Heavy metals resulted from the increase of human industrial activity are introduced into the environment through rainfall and wastewater, and have harmful effects on inhabitants. In this study, we investigated biological responses such as survival rate, growth rate, emergence rate and sex ratio, and morphological effects of mentum deformity in Chironomus plumosus, an indicator organism to evaluate pollutions on aquatic ecosystem. The survival rate of C. plumosus showed time- and dose-dependent decrease after chromium and copper exposures. Growth rate decreased at $4^{th}$ day after chromium exposure and significantly reduced at exposure to relatively high concentration (copper $1000mg\;L^{-1}$) for all exposure times. In addition, we observed that the emergence rate by exposure to copper $1000mg\;L^{-1}$ was significantly lower than that of the control group. The imbalance of sex ratios showed at relatively low concentrations (chromium 10 and $50mg\;L^{-1}$) with the high proportion of female and at the relative high concentration (copper $1000mg\;L^{-1}$) with the high proportion of male. Furthermore, the morphological mentum deformities of C. plumosus observed in the exposed group according to chromium and copper exposure. These results suggest that the heavy metal exposure in environment may influence biosynthetic and morphological stresses of benthic invertebrate C. plumosus, and aquatic midge C. plumosus are potential indicators for toxicity assessment of heavy metals such as chromium and copper.

In this study, we investigated the possibility of Kaempferia Galanga(KG) hot water extract on the antioxidant, cytotoxic and anti-inflammatory efficacy as a cosmetic ingredient. Antioxidant effects were evaluated based on DPPH and ABTS radical scavenging activity, FRAP assay, and total polyphenol contents. The MTT assay was used to confirm the cell toxicity in mouse macrophage RAW264.7 cells. Anti-inflammatory effects were also investigated in LPS-induced RAW264.7 cells by measuring secretion of NO, $TNF-{\alpha}$ and iNOS, $TNF-{\alpha}$ mRNA expression level. As a result, DPPH and ABTS radical scavenging activities were increased in a concentration-dependent manner. The ferric reducing antioxidant power(FRAP) was the highest at 5 mg/mL as 24.5 uM. The measurements of total polyphenol content was $1.28{\pm}0.064mg\;GAE/g$. The cytotoxicity of the KG extract results showed no cytotoxicity at concentration of 0.625 to 2.5 mg/mL. In addition, the extract of KG significantly suppressed the LPS-induced nitrite, $TNF-{\alpha}$ secretion and the mRNA expression of iNOS, $TNF-{\alpha}$ in RAW264.7 cells. Taken together, these data suggest that the KG hot water extracts can be used as a safe and functional cosmetic raw material.

The purpose of this study was to examine the growth plate, femoral bone length, bone mineral density, and blood composition in various experimental animals fed with oriental medicinal herbs containing growth factors. First, the lengths of the bone growth plates of the positive control (PC) group (fed with Astragalus membranaceus) and the Gh-199 and Sh-188 groups were increased when compared to group N. The Gh-199 group showed a greater increase in bone growth when compared with the PC group. In terms of the femoral bone length and bone mineral density, the effect of both Gh-199 and Sh-188 powders were as good as those of the PC group, and the Gh-199 powder showed a positive effect. Conversely, in the PC group, unlike the Gh-199 and Sh-188 groups, the aspartate aminotransferase(AST) and alanine aminotransferase(ALT) activities in the blood were increased, indicating that A. membranaceus is toxic to the body. Both the PC and Sh-188 groups also showed higher insulin-like growth factor-1(IGF-1) activity when compared with the Gh-199 group. Overall, the bone growth plate, femoral bone length, and bone mineral density measurements, and the blood analysis showed positive results in the group treated with Gh-199, and no specific toxicity of the herbal medicine in the body was evident.

Objectives : This study was conducted to evaluate the efficacy of a complex mixture of natural substances of ginseng and baeknyeoncho on the arthritic rats. Methods : In vitro experiments were conducted to ensure the stability of the complex. After setting toxicity and concentration by MTT assay, the antioxidant effect was measured through DPPH and ABTS radical scavenging activity. To confirm the anti-inflammatory effects of the complex, levels of nitric oxide (NO) and pro-inflammatory cytokines (IL-1β, TNF-α) were measured in LPS-treated macrophage cell lines (RAW264.7). We injected monosodium iodoacetate (MIA) 50 μl (60 mg/ml) into knee joints of rats to induce osteoarthritis. The rats were divided into three groups (normal (n=5), control (n=5), and OR (n=5) group). The control group consumed 2 mg/kg of physiological saline once a day for 4 weeks, and the OR group was mixed at a concentration of 416.5 mg/kg of Baengnyeoncho (O) and 208.25 mg/kg of red ginseng (R) and ingested 1 mL each 5 days a week. Results : This complex increased the DPPH and ABTS radical scavenging rate. The complex decreased NO production and pro-inflammatory cytokine production of macrophages. In the OR group, the secretion of cytokine in serum was decreased. In histopathological examination, the joint tissue of the composite showed less damage to the synovial membrane, cartilage, and fibrous tissue than the control group. Conclusions : As a result of this study, natural complexes have antioxidant, anti-inflammatory and cartilage protection effects. Therefore, we expect the complex to be effective in treating osteoarthritis.

Objectives : Daesiho-tang (DSHT) has been widely used in the treatment of cerebral infarct in traditional medicine. However, there was not report on the anti-obesity-related diseases efficacy of DSHT. In this study, we investigated the effects for the new formulation of DSHT, on the adipocyte differentiation cycle in 3T3-L1 cells. Methods : 3T3-L1 cells were treated with DSHT (50, 100, $200{\mu}g/m{\ell}$) during differentiation for 6 days. Also, the inhibitory effect of DSHT against 3T3-L1 adipogenesis was evaluated in various stage of adipogenesis such as early (0-2day), intermediate (2-4day), and terminal stage (4-6day). The accumulation of lipid droplets was determined by Oil Red O staining. and, the expressions of genes related to adipogenesis were measured by RT-PCR and Western blot analyses. Results : DSHT showed inhibitory activity on adipocyte differentiation at 3T3-L1 preadipocytes without affect cell toxicity as assessed by measuring fat accumulation and adipogenesis. In addition, DSHT significantly reduced the expression levels of several adipocyte marker genes including proliferator activated $receptor-{\gamma}$ ($PPAR-{\gamma}$) and CCAAT/ enhancer-binding $protein-{\alpha}$ ($C/EBP-{\alpha}$). Also, the anti-adipogenic effect of DSHT was strongly limited in the intermediate (2-4 day), terminal stage (4-6 day) of 3T3-L1 adipogenesis. In addition, the DSHT treatment down- regulated mRNA expression levels of $PPAR-{\gamma}$,, $C/EBP-{\alpha}$ in mature 3T3-L1 adipocytes. Conclusions : These results suggest that, the ability of DSHT has inhibited overall adipogenesis and lipid accumulation in the 3T3-L1 cells. The new formulation of DSHT may be a promising medicine for the treatment of obesity and related metabolic disorders.
