  • Background : The purpose of this study was to investigate the anti-inflammatory properties of stems and leaves of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. (ES) from Gangwon-do. Methods and Results : Stems and leaves of ES were collected from two areas in Gangwon-do: Cheorwon-gun and Samcheok-si. Samples were extracted with water by using the pressurized liquid extraction method and with 70% prethanol A by using the heat reflux extraction method. The anti-inflammatory effects of ES were evaluated through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide(MTT), lactate dehydrogenase(LDH) assay, nitric oxide(NO) assay, enzyme-linked immunosorbent assay(ELISA), and Western blot analysis in RAW 264.7 macrophages stimulated with lipopolysaccharide (LPS). 1) Results showed that ES leaf extractions were not cytotoxic at a concentration of up to 30 ㎍/㎖. The leaves of 70% prethanol A extractions of ES(30 ㎍/㎖) inhibited NO, interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) production and decreased the protein level of cyclooxygenase 2(COX-2). There was no significant change in the protein level of inducible nitric oxide synthase(iNOS). The stem extractions of ES did not exhibit anti-inflammatory effects. Conclusions : In this study, the leaves of 70% prethanol A extractions of ES demonstrated anti-inflammatory effect on RAW 264.7 macrophages. The 70% prethanol A extractions have a relatively higher anti-inflammatory effect on RAW 264.7 macrophages than water extractions.

  • Purpose : Skin is the primary barrier to protect the body from various exogenous factors. Among them, UVB exposure can cause the induction of not only excessive inflammatory responses but also the degradation of extracellular matrix (ECM), including collagen and elastin. This study tried to investigate the ameliorative effect of Persicaria perfoliata ethanol extract (PPEE) on UVB-irradiated photodamage through the regulation of activator protein (AP)-1, phosphoinositide 3-kinase (PI3K)/Akt, and mitogen-activated protein kinase (MAPK) signaling molecules in HaCaT cells. Methods : The cytotoxicity of PPEE on HaCaT cells was evaluated by the WST-1 assay. The 80 mJ/cm2 of UVB (312 nm) was irradiated on HaCaT cells to induce the photodamage. Western blot analysis was conducted to investigate the protein expression levels of cyclooxygenase (COX)-2, matrix metalloproteinase (MMP)-9, and heme oxygenase (HO)-1 for ameliorative status by PPEE treatment in UVB-exposed HaCaT cells. In addition, the activated status of the inflammatory transcription factor, AP-1, as well as upstream signaling molecules, PI3K/Akt, and MAPK, were also evaluated by Western blot analysis. Results : Any cytotoxic effect was not induced at the concentration up to 200 ㎍/ml by PPEE treatment. Protein expression levels of COX-2 and MMP-9 were significantly down- and up-regulated by PPEE treatment. The inflammatory transcription factor AP-1, stimulated by UVB irradiation, was also significantly attenuated by PPEE treatment. The phosphorylated status of PI3K/Akt and MAPK were mitigated by PPEE treatment in UVB-exposed HaCaT cells. Moreover, PPEE treatment potently accelerated the expression of HO-1 and its transcription factor, nuclear factor-erythroid 2-related factor (Nrf)2, which is known for its anti-inflammatory activity. Conclusion : Consequently, PPEE treatment significantly regulated COX-2 and MMP-9 expressions in UVB-irradiated HaCaT cells. The inflammatory transcription factor AP-1, along with upstream signaling molecules PI3K/Akt and MAPKs, were also attenuated by PPEE treatment in UVB-exposed HaCaT cells. Additionally, PPEE treatment exaggerated HO-1 expression and Nrf2 activation, which might have contributed to the anti-inflammatory activity of PPEE. These results indicate that PPEE could be a candidate for attenuating UVB-induced photodamage in human skin.

  • In this study, we investigated anticarcinogenic effects of extracts from Gloiopeltis tenax (GT). GT was extracted with methanol (GTM), which was then further fractionated into four fractions by using solvent fractionation method, affording methanol (GTMM), hexane (GTMH), butanol (GTMB) and aqueous (GTMA) soluble fractions. We determined the cytotoxic effects of these fractions on cancer cells by MTT assay. Among various fractions of GT, the GTMM showed the strongest cytotoxic effect at concentration of $150{\mu}g/mL$, displaying 95.97% on HepG2 cell lines and 93.64% on HT-29 cell lines, respectively. And, the anti-proliferative effect of GT was accompanied by a marked in increase of levels of Bad, Bax, Bok and Bak protein and activation of caspase-3, caspase-7 and PARP protein. Also, we observed quinone reductase (QR) induced effects in all fraction layers of GT on HepG2 cells. The QR induced effects of the GTMM and GTMB on HepG2 cells at concentration of $60{\mu}g/mL$ showing inductive indexes of 2.86 and 2.04 compared to the control value of 1.0.

  • This study was peformed to determine the antioxidative, antimutagenic and cytotoxic effects of the natural seasoning using Lentinus edodes powder (NSLP) by DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical donating method, Ames test, and cytotoxicity, respectively. The scavenging effect on DPPH radical in ethyl acetate fraction of NSLP showed $155{\mu}g\;of\;RC_{50}$. The direct antimutagenic effects of ethanol extract and its solvent fractions of NSLP were examined by Ames test using Salmonella Typhimurium TA98 and TA100. In the Ames test, ethanol extract of NSLP alone did not exhibit any mutagenicity and most of the samples showed high antimutagenic effects against mutation induced by N-methyl-N'-nitro-N-nitroso guanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). Ethyl acetate fraction of NSLP ($200{\mu}g/plate$) showed approximately 82% inhibitory effect on the mutagenesis induced by 4NQO against TA98 strain, whereas 84% and 80% inhibitions were observed on the mutagenesis induced by 4NQO and MNNG against TA100 strain. In anticancer effects of ethanol extract and its solvent fractions of NSLP against cancer cell lines including human lung carcinoma (A549), human breast adenocarcinoma (MCF-7), human hepatocellular carcinoma (Hep3B), human cervical adenocarcinoma (HeLa) and human gastric carcinoma (AGS) were investigated. The treatment of 1 mg/mL ethyl acetate fraction of NSLP showed strong cytotoxicity of 56.7%, 84.9%, 64.6%, 85.1% and 71.5% against A549, MCF-7, Hep3B, HeLa and AGS, respectively. In contrast 1 mg/mL treatment of NSLP extract and its solvent fractions had only $4{\sim}40%$ cytotoxicity on human transfomed primary embryonal kidney cell (293). From this result, it is suggested that NSLP is believed to have possible antioxidative, antimutagenic and anticancer capacities.

  • Purpose: This study was performed to investigate the effects of immune cell activation and the antitumor effect for the combination of treatment with X-irradiation and E/eutherococcus senticosus Maxim Root (ESMR) on mouse tumor cells. Materials and Methods: ESMR (250g) was extracted with 80% methanol, concentrated under decompression and lyophilized. To determine whether ESMR is able to activate the immune cells or not, the proliferation of splenocytes in vitro and the number of B cells and T cells in splenic lymphocytes in ESMR-pretreated mice were evaluated. X-irradiation was given to the mouse fibrosarcoma tumor cells (FSa II) by 250 kv X-irradiation machine. The cytotoxicity of ESMR was evaluated from its ability to reduce the clonogenecity of FSa II cells. In X-irradiation alone group, each 2, 4, 6 and 8 Gy was given to FSa II cells. In X-irradiation with ESMR group, 0.2 mg/ml of ESMR was exposed to FSa II cells for 1 hour before X-irradiation. Results: The proliferation of cultured mouse splenocytes and thymocytes were enhanced by the addition of ESMR in vitro. The number of B cells and T cells in mouse splenic lymphocytes was significantly increased in ESMR pretreated mice in vivo. In FSa II cells that received a combination of 0.2 mg/ml of ESMR with X-irradiation exposure, the survival fraction with a dose of 2, 4 and 6 Gy was $0.39{\pm}0.005$, $0.22{\pm}0.005$ and $0.06{\pm}0.007$, respectively. For FSa II cells treated with X-irradiation alone, the survival fraction with a dose of 2, 4 and 6 Gy was $0.76{\pm}0.02$, $0.47{\pm}0.008$ and $0.37{\pm}0.01$. The difference in the survival fraction of the mouse FSa II cells treated with and without ESMR was statistically significant (p<0.05). Conclusion: Treatment with ESMR increased cell viability of mouse splenocytes in vitro and especially the subpopulation of B cells and T cells in splenocytes in ESMR-pretreated mice. However, treatment with ESMR did not increase the level of Th and Tc subpopulations in the thymocytes. Treatment with the combination of ESMR and X-irradiation was more cytotoxic to mouse tumor cells than treatment with X-irradiation alone; this finding was statistically significant.

  • Platycodin D is a major constituent of triterpene saponins, which is found in the root of Platycodon grandiflorum, Platycodi Radix, which is widely used in traditional Oriental medicine for the treatment of many chronic inflammatory diseases. Several pharmacological effects of this compound have been reported recently, such as anti-inflammation, immunogenicity, anti-adipogenesis, lowered cholesterol, and anti-cancer activity. However, the mechanism by which this action occurs is poorly understood. In this study, we found that platycodin D greatly increased the potential of the anti-proliferative effect in various cancer cell lines. Our data revealed that platycodin D treatment resulted in a time- and concentration-response growth inhibition of U937 cells by inducing apoptosis, as evidenced by the formation of apoptotic bodies, chromatin condensation, and the accumulation of cells in the sub-G1 phase. Apoptosis induction of U937 cells by platycodin D correlated with an increase in the Bax/Bcl-2 ratio and caused the down-regulation of IAP family members. In addition, platycodin D treatment resulted in proteolytic activation of caspase-3, the concomitant degradation of poly(ADP-ribose) polymerases, and the collapse of the mitochondria membrane potential (${\Delta}{\Psi}_m$). However, the cytotoxic effects induced by platycodin D treatment were significantly inhibited by z-DEVD-fmk, a caspase-3 inhibitor, which demonstrated the important role that caspase-3 played in the observed cytotoxic effect. These findings suggest that platycodin D may be a potential chemotherapeutic agent for use in the control of human leukemia U937 cells. These findings also provided important new insights into possible molecular mechanisms of the anti-cancer activity of platycodin D.

  • This study was performed to determine the antimutagenic and anticytotoxic effects of soybean paste (doenjang) added deep sea water salt and see tangle in Salmonella Typhimurium TA98, TA100 and human cancer cell lines. In the Ames test, methanol extract of doenjang did not exhibit any mutagenicity but showed substantial inhibitory effects against mutation induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and 4-nitroquinoline-1-oxide (4NQO). The methanol extracts of doenjang ($200{\mu}g$/plate) added deep sea salt and see tangle (doenjang C) showed approximately 89.1% and 70% inhibitory effect on the mutagenesis induced by MNNG and 4NQO against TA100 strain, whereas 84.4% inhibitions were observed on the mutagenesis induced by 4NQO against TA98 strain. The cytotoxic effects of doenjang methanol extracts against the cell lines with human cervical adenocarcinoma (HeLa), human hepatocellular carcinoma (Hep3B), human gastric carcinoma (AGS), human lung carcinoma (A549) and human breast adenocarcinoma (MCF-7) were inhibited with the increase of the extract concentration. The treatment of 1.0 mg/mL doenjang C of methanol extracts showed strong cytotoxicities of 71%, 74.4%, 66.2%, 77.3%, and 71.2% against HeLa, Hep3B, AGS, A549, and MCF-7, respectively. In contrast 1 mg/mL treatment of doenjang C methanol extracts had only $10{\sim}40%$ cytotoxicity on normal human embryonal kidney cell (293). Doenjang methanol extract inhibited significantly the tumor growth in mice injected sarcoma-180 cells. Especially, doenjang C methanol extract showed an inhibition of tumor cell activity of 33% by the administration of 25 mg/kg methanol extracts.

  • Hibiscus cannabinus L. is a plant in the Malvaceae family, that was seeded at June 1st in 2010 and harvested at November 18th. The present study was designated to investigate the safety for host cells, antibacterial effects of Hibiscus cannabinus L. of flower (HCME-F) or leaf (HMEF-L) methanol extract for typical Gram's positive bacteria (St. aureus and Str. epidermidis) or Gram's negative bacteria (S. typhimurium and E. coli). In treatment of different concentrations of HCME-F or HMEF-L (1, 50 and $100{\mu}g/ml$), cytotoxic effects were not shown to RAW 264.7 cells until 24 h incubation. In determination of antibacterial activity of HCME-F or HMEF-L, the antibacterial activities for St. aureus and Str. epidermidis were markedly increased compared to that of untreated control group, but antibacterial activity of HCME-F or HMEF-L for S. typhimurium and E. coli were not changed. Taken together, we demonstrated that methanol extract of HCME-F or HMEF-L showed the safety for RAW 264.7 cells and antibacterial activities for Gram's positive pathogenic bacteria St. aureus and Str. epidermidis. These findings suggest that a methanol extract of Kenaf flower or leaf may be useful alternatives of conventional chemotherapies for dermatitis and mastitis causing Gram's positive pathogens such as Stapylococcus spp. and Streptococcus spp. in domestic animals and humans.

  • Litsea populifolia, a plant species of the Lauraceae family, is widely distributed in the tropical and subtropical areas of Asia. The phylogenetic relationships and botanical characteristics of L. populifolia have been reported; however, its anti-oxidative and anti-cancer activities remain unclear. In this study, we evaluated the anti-oxidative and anti-cancer effects of ethanol extracts of L. populifolia (EELP) together with the molecular mechanism of its anti-cancer activity in human lung adenocarcinoma A549 cells. EELP showed significant anti-oxidative effects with a 50% inhibitory concentration at $11.71{\mu}g/ml$, which was measured by the 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay. EELP exhibited cytotoxic activity and induced cell cycle arrest at the G1 phase in A549 cells in a dose-dependent manner, whereas EELP did not have the cytotoxic effect on the normal human lung cell line IMR90. Treatment with EELP also resulted in a decreased expression of G1/S transition-related molecules-including cyclin-dependent kinase (CDK) 2, CDK6, cyclin D1, and cyclin E-both for the transcription and translation levels. EELP-induced G1 arrest was associated with the phosphorylation of checkpoint kinase 2 (CHK2), p53, cell division cycle 25 homolog A (CDC25A), and the reduction of CDC25A expression in A549 cells. Collectively, these results suggest that EELP may exert an anti-cancer effect by cell cycle arrest at the G1 phase through both p53-dependent and p53-independent (ATM/CHK2/CDC25A/CDK2) pathways in A549 cells.
