This study was conducted in order to compare the biological activities of leaf and root water extracts of Smilax china L. (SC) by measuring the total polyphenol and flavonoid contents, anti-oxidant activity, inhibitory effect on ${\alpha}$-glucosidase, and anti-inflammatory gene expression. The total polyphenol and flavonoid contents of SC leaf (SCLE) and root (SCRE) water extracts were 127.93 mg GAE/g and 39.50 mg GAE/g and 41.99 mg QE/g and 1.25 mg QE/g, respectively. The anti-oxidative activities of SCLE and SCRE were measured using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) radical scavenging activity assay and reducing power assay. Both SCLE and SCRE scavenged radicals in a concentration-dependent manner, and SCLE showed stronger radical scavenging activity and reducing power than SCRE; however, both SCLE and SCRE exhibited lower activities than ascorbic acid. Compared to the anti-diabetic drug acarbose, which was used as a positive control, SCLE and SCRE exhibited low ${\alpha}$-glucosidase inhibition activities; nevertheless, the activity of SCLE was 3.7 fold higher than that of SCRE. Finally, SCLE caused significantly decreased expression of the LPS-induced cytokines, iNOS, and COX-2 mRNA in RAW264.7 cells, indicating anti-inflammatory activity. These results indicate that SCLE might be a potential candidate as an anti-oxidant, anti-diabetic, and anti-inflammatory agent.

It confirmed the applicability as an anti-inflammatory material from Rubus occidentalis seed (RSE) extract. In HaCaT cells to evaluate the anti-inflammatory potential as a material RSE extract on the activity of the inflammatory factors caused by UVB and $IFN-{\gamma}/TNF-{\alpha}$. We measured the activity of ROS, interleukin-$1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6) and interleukin-8 (IL-8) by ROS-Glo $H_2O_2$ assay and ELISA kit. Our results showed that the RSE extracts inhibit the UVB and $IFN-{\gamma}/TNF-{\alpha}$-induced ROS activities and expression of $IL-1{\beta}$, IL-6 and IL-8 in a dose-dependent manner. Also it was found that inflammatory mediators of the expression of cyclooxygenase-2 (COX-2) inhibition were also brought, the expression of which is increased $PGE_2$ by COX-2 also inhibited. Finally RSE extracts measure the seed expression of filaggrin in the skin barrier, the main factor of the extract could be confirmed to increase the expression of the filaggrin damaged as a result of this concentration-dependent manner. Through this, it was able to confirm that the efficacy RSE extract to protect the inflammation by restoring the damaged layers of the epidermis. Results from more than RSE extract was able to confirm that the extract that has anti-inflammatory effects by improving the inflammation being produced from UVB.

Objective : The effect of water extract of Chungjogupae-tang (CJGPT) was investigated on the growth of human lung carcinoma A549 cells. Methods : MTT assay and fluorescent microscope performed to compare and examine the efficacy of CJGPT treatment on the cytostaticity of lung cancer cells in proportion to time and doses, and DAPI staining and Western blot analysis were used to examine their effect on apoptosis. In addition the quantitative RT-PCR was used to examine to lung cancer cells growth and Progtaglandin E2 and Telomerase activity were measured Results : Exposure of A549 cells to CJGPT resulted in the growth inhibition and apoptosis in a dose-dependent manner as measured by MTT assay and fluorescent microscope. The antiuoliferative effect by CJGPT treatment in A549 cells was associated with morphological changes such as membrane shrinking and cell rounding up. CJGPT treatment resulted in an up-regulation of cyclin-dependent kinase inhibitor p21(WAF1/CIPl) in a p53-independent fashion. We found that CJGPT treatment decreased the levels of cyclooxygenase (COX)-2 and inducible nitric oxide synthease (iNOS) expression without significant changes in the expression of COX-1, which was correlated with a decrease in protaglandin E2 (PGE2) synthesis. CJGPT treatment also inhibited the levels of human telomerase reverse transcriptase (hTERT) and telomerase-associated protein (TEP)-1 mRNA expression, however the activity of telomerase was slightly increased by CJGPT treatment. Conclusion : These findings suggested that CJGPT-induced inhibition of human lung carcinoma A549 cell growth was connected with the induction of apoptotic cell death and the results provided important new insights into the possible molecular mechanisms of the anti-cancer activity of CJGPT.

Epidemiology studies have reported a reduced incidence of colon cancer among populations that consume a large quantity of ${\omega}3-polyunsaturated$ fatty acids (${\omega}3-PUFAs$) of marine origin. Herein, we demonstrated a mechanism of anticancer action of ${\omega}3-PUFAs$, showing that they suppressed invasion and tumorigenicity in colon cancer cells. Docosahexaenoic acids (DHA) inhibited the cell growth of HT29 cells. This action likely involved apoptosis, given that the DHA treatment increased the cleaved form of PARP and sub G1 cells. Moreover, the invasiveness of HT29 cells was inhibited following DHA treatment, whereas arachidonic acid (AA) had no effect. The levels of Matrix-metalloproteinase-9 (MMP-9) and MMP-2 mRNA decreased after DHA pretreatment. DHA treatment inhibited MMP-9 and MMP-2 promoter activities and reduced VEGF promoter activity. DHA pretreatment also inhibited the activities of prostaglandin-2 (PGE2)-induced MMPs and the VEGF promoter. Cyclooxygenase-2 (COX-2) overexpression increased the activity of MMPs and that of the Vascular endotherial growth factor (VEGF) promoter in HT29 cells, and DHA inhibited NF-kB and COX-2 promoter reporter activities. As shown by in vivo experiments, when mouse colon cancer cells (MCA38) were implanted into Fat-1 and wild-type mice, both the tumoral size and volume were dramatically inhibited in Fat-1 transgenic mice. Furthermore, TUNEL-positive cells increased in tumors from Fat-1 mice compared with wild mice. In immunohistochemistry, the intensity of CD31 in Fat-1 tumors was weaker. These findings suggest that ${\omega}3-PUFAs$ may inhibit tumorigenicity and angiogenesis as well as cancer cell invasion by suppression of COX-2, MMPs and VEGF via the reduction of NF-kB in colon cancer.

This study was carried out to compare the anti-inflammation effects of various fruiting body of Ganoderma species and Cordyceps militaris, Phelinus linteus extracts. We concentrated Ganoderma species and other medicinal mushrooms by extracting with ethanol. And We made it $100{\mu}g/ml$ concentration. As a result of nitrite scavenging activity, in the contrast to the positive control; Ascorbic acid was 25%, ASI 7080 of Ganoderma species was disappeared up to around 40%. And in the contrast to Ascorbic acid was 55%, ASI 7002 was 78.5% that was the highest anti-inflammation effect in the result of "No assay test". The Cordyceps militaris showed 75% and Hericium erinaceus showed 59.7% of anti-inflammation effect. As a result of the fungus yield control test of $TNF-{\alpha}$ through ELISA method to ASI 7002 of Ganoderma species that showed the highest anti-inflammation, it was reduced as same as LPS non-treatment. We extracted RNA from ASI 7002 Ganoderma species 10, 50, $100{\mu}g/ml$ concentration and LPS $10{\mu}g/ml$ of Raw 264.7 cell. And we tested the expression of iNOS, COX-2 and TNF-a that are kinds of inflammation gene after synthesizing RNA with cDNA. Finally we could find that iNOS, COX-2 and TNF-a were all controlled expression in the result of above experiment.

${\beta}$-lapachone, a quinone of lapachol extracted from the bark of the lapacho tree, has been found to induce apoptosis in various human cancer cells. In the present study, we investigated further possible mechanisms by which ${\beta}$-lapachone exerts its pro-apoptotic action in cultured human lung cancer A549 cells. ${\beta}$-lapachone treatment resulted in inhibition of growth and induction of apoptosis in a concentration-dependent manner, as determined by MTT assay and flow cytometry analysis. The induction of apoptosis by ${\beta}$-lapachone was associated with up-regulation of the expression of p53 and p21 in both transcriptional and translational levels, and the phosphorylation of p53. In addition, ${\beta}$-lapachone activated caspase-3 and -9, and induced degradation of caspase-3 target proteins such as poly (ADP-ribose) polymerase (PARP) and ${\beta}$-catenin. Furthermore, ${\beta}$-lapachone treatment caused a progressive decrease in the expression levels of cyclooxygenase (COX)-2 without significant changes in the levels of COX-1, which was correlated with a decrease in prostaglandin E2 synthesis. Taken together, these results indicated that ${\beta}$-lapachone may have therapeutic potential in human lung cancer treatment.

The functions of anti-oxidation and anti-inflammation were investigated with the crude 80% methanol extract, subfractions and henryin isolated from Isodon inflexus (Thunb.) Kudo (I. inflexus (Thunb.) Kudo). Antioxidative ability was evaluated by bioassays using 2, 2-diphenyl-1-1-picrydrazyl (DPPH) free radical scavenging activity, xanthine oxidase inhibition, and superoxide radical scavenging effects. Ethyl acetate and butanol fractions exhibited free radical scavenging activity on superoxide with $IC_{50}$ values of $0.9{\mu}g/mL$, $0.2{\mu}g/mL$, respectively, which were stronger activity than that of allopurinol ($2.2{\mu}g/mL$) as reference. For the inhibition of anti-inflammatory activity in RAW 264.7 cell, the ethyl acetate fraction showed strong inhibition activity NO production, and henryin isolated from its subfraction reduced the activity in a dose-dependent manner. Ethyl acetate fraction and henryin suppressed not only mRNA expression of iNOS and COX-2, but also the mRNA expression of pre-inflammatory cytokines such as, TNF-${\alpha}$, 1L-$1{\beta}$, IL-6, in a dose-dependent manner. These results suggested that ethyl acetate fraction of I. inflexus (Thunb.) Kudo has considerable potential as a cosmetics ingredient with an antioxidant and anti-inflammatory effects and henryin can be applied as an functional reference.

This study was performed to evaluate the effect of Carthami tinctorius(HH) on osteoblast function and gene expression. The osteoblasts separated from the rat calvariae were cultivated to evaluate the cell function, and MG-63 cell was also cultivated for the test of mRNA synthesis. In this experiments, cell proliferation of rat calvarial cells was increased by HH. PKC activity, intracellular free calcium level and collgen synthesis from calvarial cells were increased by HH, but not PKA activity. And the mRNA of $PLA_2$, COX-2, and $PGE_2$ synthase from MG-63 were decreased by HH, but the mRNA of prostacyclin synthase was increased. It is concluded that HH might increase the proliferation of calvarial cell resulted from augumentation of osteoblast activity and its mRNA synthesis.

Objective : Lonicera japonica (Caprifoliaceae) has long been used for treatment of infectious diseases in oriental countries. The aim of this study was to investigative the effect by which the aqueous extract from flower of L. japonica (LJFAE) inhibited the lipopolysaccharide (LPS)-induced inflammatory mediators in murine macrophages, RAW 264.7 cells Methods : The dried flowers of L. japonica were extracted with distilled water at $100^{\circ}C$ for 7 h. The extract was filtered through 0.45 ${\mu}m$ filter, freeze-dried. The dried extract was dissolved in Hank's balanced salt solution (HBSS) and filtered through 0.22 ${\mu}m$ filter before use. Accumulated nitrite, an oxidative product of nitric oxide (NO), was measured in the culture medium by the Griess reaction. The levels of prostaglandin E2 (PGE2), tumor necrosis factor-$\alpha$ (TNF-$\alpha$), interleukin-1$\beta$ (IL-1$\beta$), and IL-6 production, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression were measured by enzyme-linked immunosorbent assay and Western blot analysis. Results: LJFAE (10-400 ${\mu}g$/ml) per se had no cytotoxic effect in unstimulated macrophages, but LJFAE concentration-dependently reduced NO, PGE2, TNF-, IL-l, and IL-6 production and COX-2 activity caused by stimulation of LPS. The levels of iNOS and COX-2 protein expressions were markedly suppressed by the treatment with LJFAE in a concentration dependent manner. Conclusions : These results suggest that LJFAE suppress the NO and PGE2production in macrophages by inhibiting iNOS and COX-2 expression and these properties may contribute to the anti-inflammatory activity of Lonicera japonica.
