  • Lonicera caerulea (Honey berry, HB) has been used in medical treatment in Russia, Japan, China and Korea. It has high level of vitamin C and polyphenolics. Polyphenolics can improve anti-inflammatory effect and prevent cancer, diabetes mellitus type 2. Also, Vitamin C is a representative anti-oxidant. however, it is still unknown what effect it will have on the oxidation stress of the reproductive system. In previous studies, ROS can be produced when it is exposed to heat stress and has negative effect on sperm's maturation, capacitation, hyperactivation, acrosome reaction and fusion of egg and sperm. Therefore, the purpose of this study is to investigate the antioxidant effects of L. Caerulea on the sperm and mice. At first, it conducted using ICR mouse (n = 20) for 4 weeks. There are four groups of mice (n = 5 per group). Also, L. Caerulea was taken by oral gavage. Group I (control) kept at 23℃-27℃ and administer D.W (0.5 mL/day), Likewise, Group II (HB) kept at room temperature but gave HB (250 mg/kg, 0.5 mL/day), Group III (HB + HS) received heat stress (40℃) using hyperthermia induction chamber and gave HB at same dose. and Group IV (HS) exposed heat stress only. Mainly, we showed degree of gene expression using Western blot in SOD, HSP 70, 17β-HSD and Real-time PCR. It can find correlation between intracellular activity like steroid hormone, apoptosis under ROS and antioxidant activity of L. Caerulea.

  • BACKGROUND/OBJECTIVES: Yacon (Samallanthus sonchifolius), a common edible plant grown throughout the world, is well known for its antidiabetic properties. It is also known to have several other pharmacological properties including anti-inflammatory, anti-oxidant, anti-allergic, and anti-cancer effects. To date, the effect of yacon on gliomas has not been studied. In this study, we investigated the effects of yacon on the migration and proliferation of C6 glioma cells stimulated by fetal bovine serum (FBS). MATERIALS/METHODS: Cell growth and proliferation were determined by evaluating cell viability using an EZ-Cytox Cell Viability Assay Kit. FBS-induced migration of C6 glioma cells was evaluated by performing the scratch wound healing assay and the Boyden chamber assay. We also used western blot analysis to determine the expression levels of extracellular signal-regulated kinase 1/2 (ERK1/2), a major regulator of migration and proliferation of glioma cells. Matrix metallopeptidase (MMP) 9 and TIMP-1 levels were measured by performing reverse transcription PCR. RESULTS: Yacon ($300{\mu}g/mL$) reduced both the FBS-induced proliferation of C6 glioma cells and the dose-dependent migration of the FBS-stimulated C6 cells. FBS-stimulated C6 glioma cells treated with yacon (200 and $300{\mu}g/mL$) showed reduced phosphorylation of ERK1/2 and inhibition of MMP 9 expression compared to those shown by the untreated FBS-stimulated C6 cells. In contrast, yacon (200 and $300{\mu}g/mL$) induced TIMP-1 expression. CONCLUSIONS: On the basis of these results, we suggest that yacon may exert an anti-cancer effect on FBS-stimulated C6 glioma cells by inhibiting their proliferation and migration. The most likely mechanism for this is down-regulation of ERK1/2 and MMP9 and up-regulation of TIMP-1 expression levels.

  • Obesity is a major risk factor for various metabolic diseases such as cardiovascular disease, hypertension, and type 2 diabetes mellitus. In this study, we prepared ethanol extracts from Agastache rugosa (ARE), Chrysanthemum zawadskii (CZE), Mentha arvensis (MAE), Perilla frutescens (PFE), Leonurus sibiricus (LSE), Gardenia jasminoides (GJE), and Lycopus coreanus (LCE). The anti-oxidant and anti-adipogenic effects were evaluated. The $IC_{50}$ values for ascorbic acid and LCE against 2,2-diphenyl-1-picrylhydrazyl radicals were $246.2{\mu}g/mL$ and $166.2{\mu}g/mL$, respectively, followed by ARE ($186.6{\mu}g/mL$), CZE ($198.6{\mu}g/mL$), MAE ($337.1{\mu}g/mL$), PFE ($415.3{\mu}g/mL$), LSE ($548.2{\mu}g/mL$), and GJE ($626.3{\mu}g/mL$). In non-toxic concentration ranges, CZE had a strong inhibitory effect against 3T3-L1 adipogenes (84.5%) than those of the other extracts. Furthermore, the anti-adipogenic effect of CZE is largely limited in the early stage of adipogenesis, and we revealed that the inhibitory role of CZE in adipogenesis is required for the activation of Wnt signaling. Our results provide scientific evidence that the anti-adipogenic effect of CZE can be applied as an ingredient for the development of functional foods and nutri-cosmetics for obesity prevention.

  • This research was performed to investigate the protective effect of Chungpesagan-tang (CST) from hypoxia/reperfusion induced-PC12 cell damage. To elucidate the mechanism of the protective effect of CST, cell viability, changes in activities of superoxide dismutase, glutathione peroxidase, catalase, caspase 3 and the production of malondialdehyde were observed after treating PC12 cells with CST which was metabolized by rat liver homogenate. Pretreatment of CST with liver homogenate appeared to increase its protective effect against hypoxia/reperfusion insult. The result showed that CST exhibited the highest protective effect against hypoxia/reperfusion at the dose of $1\;{\mu}g/ml$ in PC12 cells, probably by recovering the redox enzyme activities and MDA to control level.

  • Purpose : This study examined the non-toxic and the anti-oxidative effect of Dioscoreae Rhizoma on PC12 cells. Sanyak(Dioscoreae Rhizoma; chinese yam, shan yao) is well-known for its curing power for kidney, lung, spleen. Tonifies and augments the spleen and stomach. Tonifies the lung gi and augments the kidney yin. Tonifies the kidneys and also stabilizes and binds. it also binds the essence and treats spermatorrhea, frequent urination, and vaginal discharge. We are therefore interested in whether Dioscoreae Rhizoma is capable of causing abnormal apoptosis processes, and whether this condition can be rectified through Dioscoreae Rhizoma herb treatment. Methods : We used aqueous extract to treat PC12 cells with different concentrations treated with a water or a MeOH extract of Dioscoreae Rhizoma (0, x10, x20, x40, x80). The MTT (3, (4, 5-dimethyl-thiazol) 2, 5-diphenyl-tetraxolium bromide) reduction assay was employed to quantify the differences in cell activity and viability. The Bax expression level was monitored using western-blotting techniques. The patterns of the changes in expression were scanned and analyzed. Results : Bax and GSK-3${\beta}$ promotes cell death and down-regulated during the development of the PC12 cells. This is indicated that Dioscoreae Rhizoma is capable of inducing apoptosis in PC12 cells. The induced cell death and significantly inhibited by Dioscoreae Rhizoma, which can be explained by the increase in the inhibition of Bax and GSK-3${\beta}$ expression. It was also shown that Dioscoreae Rhizoma inhibits the release of $H_2O_2$ and prevents lipid peroxidation. Furthermore, the accumulation of wild type Bax protein significantly downregulated in a dose-dependent manner upon treatment with Dioscoreae Rhizoma. Conclusion : In conclusion, Dioscoreae Rhizoma can induce apoptosis via a Bax-dependent pathway or GSK-3${\beta}$ dependent pathway in PC12 cells into anti-oxidant and protective effect.

  • 35 theses conducted in Korea on the topic of senescence or anti-oxidant were classified on the basis of research methods, animals used for the experiments, and research items. Evaluating these research works with respect to the Free Radical Theory, the following conclusions were reached. 1. Of the 17 theses written in the Oriental medicine aspect, three theses used a single herb, nine theses used a complex prescription, four theses concentrated on the usage of the medicinal acupuncture, and one research paper focused on using scientific components. Common objection of these papers were on the verification of the efficacy of herbs. 2. Of the 18 these written in the Western medicine aspect, five theses used a single drug, seven theses conducted a research on the changes due to senescence, and 6 papers were on variety of topics. The main focus of these works were on the mechanism and pathology related to the senescence rather than on the suppression of senescence. 3. Among the theses written in the Oriental medicine perspective, a total of 48 herbs were utilized. 26 of these herbs has a tonification function on the Kidney. Six out of nine complex prescription mentioned above has a function of tonifying the Kidney. 4. With respect to the research subjects used on the experiments, 8 theses have used Senescence-Accelerated mice, 13 theses have used Sprague-Dawley mice, and remaining 7 papers have used human or other animals. 5. These are the categorization of the research items used: the weight (11) and weight changes of the visceral organs (9), the measurement of the content of peroxide-disease (9), the measurement of enzyme vitality (21), the blood and urine test (10), the experiment concerning immune system (3), the influence on the hepatic capability of metabolizing foreign substance (3), the effect on hepatic cell protection (3), the measurement of both the suppression of Free Radical and ability to create Free Radical (2), the measurement of effect of suppresing MDA(malondialdehyde) (4), the effect of eliminating DPPH Radical (2), and experiements about the functions (2). 6. The rate of vitalization of well known anti-oxidants such as Superoxide dismutase (SOD), Protein-bound SH, Nonprotein-bound SH, Glutathione(GSH), Catalase, and etc. were tested in 17 theses. Considering the conclusions mentioned above, the theses related to the senescence published in Korea elected different animals used for experiments, research items and the methods of research, the end result seems to be a lack of objectivity. Thus, I would argue that research methods to overcome such a deficiency need to be developed systematically.

  • Multiple lines of study have shown that Acanthopanax species have anti-oxidant and chemopreventive effect. However, the suitability of Acanthopanax sessilifloru fruit (Ogaza) as a functional food source remains to be investigated. Therefore, we have investigated the effect of Ogaza as an anti-oxidant and anti-inflammatory substance. The phenolic content of Ogaza is 56.1${\pm}$5.2 mg gallic acid equivalents (GAE) per 1 g of Ogaza. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging effects of Ogaza extract at 0.25, 0.5, 1, or 2 mg/mL were 34.0, 73.0, 194.3, or 339.7 $\mu g$/mL vitamin C equivalent antioxidnat capacity (VCEAC), respectively. Ogaza extract (1 or 2 mg/mL) inhibited LPS-induced TNF-$\alpha$ production (decrease of 22${\pm}$2% or 19${\pm}$6%, respectively). It also inhibited LPS-induced IL-6 production (decrease of 18${\pm}$2% or 24${\pm}$3%, respectively). In addition, Ogaza extract (0.25, 0.5, 1, or 2 mg/mL) inhibited COX-2 luciferase activity (decrease of 80${\pm}$1%, 83.${\pm}$7%, 96${\pm}$4%, or 98${\pm}$2%, respectively). Overall, these results indicated that Ogaza is promising as a functional food source due to its antioxidant and anti-inflammatory effects.

  • In recent year, We are concerned in anti-aging, disease-protection, long-life, many method are used in solving this problem. Recently, We heard that Luffae Fructus Retinervus(LFR) has effect of anti-aging, disease-protection, long-life. So I let made a experiment for this result. The purpose of this study is to; 1) the anti-oxidant effect of Luffae Fructus Retinervus(LFR) used for 3 methods, those are DPPH radical scavenging activity, Nitric oxide(NO) radical scavenging activity, Superoxide anion radical scavenging activity, 2) cultivation 3T3-L 1 Preadipocytes and Protein chip used for ProteoPlexTM 16-Well Murine Cytokine Array Kit. We measured level of DPPH radical scavenging activity. And we experienced that the ability of DPPH radical's elimination was increased by rising concentration of LFR. When the concentration of LFR was 5 mg/ml, the ability of DPPH radical's elimination was Maximum. We measured level of Nitric oxide(NO) radical scavenging activity. And we founded that the ability of NO radical's elimination was significant when concentration of LFR was from 1.25 mg/ml to 2.5 mg/ml. We measured level of Superoxide anion radical scavenging activity. And we founded that the ability of Superoxide anion radical's elimination was maximum when concentration of LFR was 0.3125 mg. When we inspected Antioxidative Effects with BSA, we experienced that ability of defense was increased by rising concentration of LFR. We known the immunity of LFR about 3T3-L1 Preadipocytes and gained the increase of Cytokines(IL-2, IL-4, GM-CSF) without IL-12p70, $INF-{\gamma}$, $TNF-{\alpha}$ So I guess that Luffae Fructus Retinervus(LFR) has effects of anti-aging, disease-protection, long-life, etc.
