  • Objectives The purpose of this study was to evaluate the effect of Jeopgolsan (JGS) extract on anti-oxidant, anti-inflammatory activities in RAW 264.7 cells and on factors related with fracture healing in skull fractured rat. Methods Experimental animals were divided into four groups: normal group without any treatment (Normal), contral group were treated orally with distilled water (Control), Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 200) and Experimental group were treated orally with JGS at a concentration of 200 mg/kg/day (JGS 400). Rats in each group except the normal group were induced fractures in the skull. The 1,1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activity were measured to evaluate antioxidant activity. The production of nitric oxide (NO), $interleukin-1{\beta}$ ($IL-1{\beta}$), interleukin-6 (IL-6) and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) in the RAW 264.7 cells were measured to evaluate anti-inflammatory activity. The production of osteocalcin calcitonin, carboxy-terminal telepeptides of type II collagen (CTX II), transforming growth $factor-{\beta}$ ($TGF-{\beta}$), bone morphogenetic protein-2 (BMP-2), Insulin and alkaline phosphatase (ALP) in serum of rats were measured to evaluate the effects of fracture healing at 0, 2, 4, and 6th week. X-rays were taken every 3 week from 0 to 6th week to evaluate fracture healing effect. Results 1. No cytotoxicity was observed. 2. DPPH and ABTS radical scavenging activity were increased in a concentration dependent manner, indicating anti-oxidant effect. 3. NO, $IL-1{\beta}$, IL-6, and $TNF-{\alpha}$ were not significantly changed, indicating no anti-inflammatory effect. 4. Osteocalcin, Calcitonin, $TGF-{\beta}$ and ALP were significantly increased in the experimental groups. 5. CTX II, insulin were significantly decreased in the expermental groups. 6. Radiologic examination showed that union of fracture was promoted. Conclusions From above results, JGS showed significant results in factors related with fracture healing and radiologic examination. Threfore, JGS is expected to be effective in the treatment of fracture.

  • Background: Atractylodes radix is a well-known medicinal crop having many physiological effects. This study was conducted to select useful Atractylodes japonica ${\times}$ Atractylodes macrocephala (AJM) cultivars by comparing anti-oxidative and anti-inflammatory efficacies. Methods and Results: Seven extracts from AJM cultivars were used to treat lipopolysacchride (LPS)-treated BV2 cells, and the effects on cell viability and inhibition on reactive oxygen species (ROS) and nitric oxide (NO) production were analyzed. In vitro scavenging activities of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and peroxynitrite ($NOO^-$) radicals were also investigated. Contents of total phenol, atractylenolide I, and atractylenolide III in the AJM extracts were measured using high performance liquid chromatography (HPLC) or spectrophotometry. The experiments show that none of the seven extracts was cytotoxic above 89.2% at $20-250{\mu}g/m{\ell}$. Extracts of Gowon, Dawon, Sangchul, and Huchul inhibited ROS generation in a dose-dependent manner, and Sangchul extract showed the highest inhibition on ROS production. All the AJM extracts showed effective inhibitory activity after on NO release in the LPS-treated BV2 cells, and Sangchul extract showed the highest activity. Sangchul extract had the most potent scavenging activities for $NOO^-$ and had some DPPH radical scavenging effect. Sangchul extract also had the highest content at total phenol and atractylenolide I content. Atractylenolide III was not detected in the AJM extracts. Conclusions: The results suggested that Sangchul was the most useful anti-oxidative and anti-inflammatory resource among the AJM cultivars.

  • This study investigated the biological activities and chemical characteristics of Monascus-fermented Korean red ginseng (MFRG). The comparative activities of water, ethanol, and methanol extracts from MFRGE and Korean red ginseng (RG) were tested in vitro of anti-oxidative models of linoleic acid peroxidation by thiocyanate and thiobarbituric acid (TBA) methods and DPPH ($\alpha,\alpha'$-diphenyl-$\beta$-picrylhydrazyl)radical scavenging activities. In addition, measurements of their bioactive total phenolic compounds and minerals, and extract yield, were obtained. The extract yield of each solvent extracted from MFRG and RG was aqueous by 6.58% and 5.83%, ethanol by 0.62% and 0.98%, and methanol by 1.27% and 3.04%, respectively. Total phenolic compounds were higher in all solvents extracted from MFRG than those from RG. Major mineral contents (ppm) of MFRG and RG were K by 16,936 and 22,386, Ca by 2,310 and 3,693, Mg by 2,703 and 2,647, respectively. The DPPH radical scavenging activities were higher in all solvents extracted from MFRG than those from RG, however, all these extracts exhibited a relatively low level of radical-scavenging activity compared to the butylated hydroxytoluene (BHT). In antioxidative activities determined by TBA method using linoleic acid peroxidation, 70% methanol extract from MFRG and RG showed the highest antioxidative activity at a concentration of 0.1%. These results may provide the basic data to understand the biological activities of bio-active materials derived from MFRG.

  • Objectives : Diabetes is a disease in which the body does not produce or properly use insulin. Etiological studies of diabetes and its complications showed that oxidative stress might play a major role. Therefore, many efforts have been tried to regulate free oxygen radicals for treating diabetes and its complications. Iksujisundan has been known to be effective for the treatment of diabetes. The present study was carried out to investigate the effect of Iksujisundan on renal function, peroxynitrite(ONOO-) scavenging activity and polyol pathway in streptozotocin-induced diabetic rats. Methods : The crushed Iksujisundan was extracted 3 times, each time with 3 volumes of methyl alcohol at 60$^{\circ}C$ for 24 h. The extract was filtered and evaporated under a reduced pressure using a rotary evaporator to yield 87.8g. Iksujisundan extract was orally administreted at 100 mg per 1 kg of body weight for 20 days to the diabetic rats induced by streptozotocin(60mg/kg). The effects of Iksujisundan extract on the streptozotocin-induced diabetic rats were observed by measuring the serum level of glucose, insulin, lipid components, creatinine and BUN, and also the kidney levels of superoxide anion radical(${\cdot}$O2-), nitric oxide(NO) and ONOO-, and also the enzyme activities involved in the polyol pathway. Results : The effects of Iksujisundan on the streptozotocin-induced diabetic rats with regards to body weight, blood glucose and indulin levels, creatinine and BUN levels, total cholesterol and triglyceride lavels, and HDL-cholesterol levels were all shown to be good enough to prevent and cure the diabetes and its complications. Iksujisundan inhibited the generation of ${\cdot}$O2-,NO and ONOO- in the kidney of streptozotocin-induced diabetic rats. Renal aldose reductase and sorbitol dehydrogenase activities were increased in the streptozotocin-induced diabetic rats were reversed toward natural activities. Conclusions : Iksujisundan might inhibit the development of diabetes and its complications by scavenging reactive oxygen and nitrogen species, thereby by reducing oxidative stresses and also by regulating the activities of polyol pathway enzymes, all of which could help to recover kidney function.

  • The aim of this study was to develop the new processing method for ginseng. To investigate the efficacy of the new product (the traditional rice wine steamed-red ginseng: RWS-RGS), antioxidant and anticancer effects of RWS-RGS were examined. The DPPH radical scavenging effect of RWS-RGS extracted with ethanol was increased in dose-dependent manner Especially, A3 ($3^{rd}$ traditional rice wine steamed-red ginsengs) exhibited effective DPPH radical scavenging activity. Nitrite scavenging effect of white ginseng (W.G), red ginseng (R.G) and RWS-RGS ($A1\~A9:\;1^{st}$ traditional rice wine steamed-red $ginseng\~9^{th}$ traditional rice wine steamed-red ginseng) were $25.9{\pm}4.4\%,\;12.9{\pm}1.1\%\;and\;26.2{\pm}0.1\~56.1{\pm}0.6\%$ at pH 1.2, respectively. The antitumor effects of W.G, R.G and RWS-RGS (A9) were examined in Hep3B cancer cells. Their growth inhibition against Hep3B cancer cells showed $19.6{\pm}4.5\%,\;54.5{\pm}6.1\%,\;96.3{\pm}2.4\%$ at 5,000 ppm, respectively. These result suggest that the traditional rice wine steamed ginseng will be useful product with antioxidant and antitumor effect.

  • The objective of this study was to compare antioxidant activities of green tea, rosemary, lemon and bamboo leaves extracts using three different extraction methods (80% ethanol sonication extraction, distilled water autoclave extraction, distilled water extraction at room temperature). As a result, green tea and rosemary extracts showed relatively high antioxidant activities compared with those of lemon and bamboo leaves. These green tea and rosemary extracts were subsequently added to soymilk and their mixtures were examined for antioxidant activities. Soymilk added with 10% green tea distilled water autoclave extracts and distilled water at room temperature extracts showed relatively high DPPH, $85.09{\pm}2.26%$, $84.38{\pm}1.97%$, and ABTS radical scavenging activities, $73.43{\pm}2.78%$, $81.34{\pm}4.78%$, respectively. On the other hand, soymilk added with 10% rosemary distilled water autoclave extracts showed remarkably higher DPPH radical scavenging activity while their ABTS radical scavenging ability was similar to that of non-added soymilk. In conclusion, our results suggest that the addition of green tea distilled water autoclave extracts, distilled water at room temperature extracts and rosemary distilled water autoclave extracts to soymilk could contribute to the development of added value soymilk products with increased antioxidant activities.

  • In this study, the canadian peat moss extract was purified by a supercritical 2 using three different conditions and assessed its biological activities. Peat moss was extracted by acid-alkaline extraction method (sample 1) and purified by a supercritical $CO_2$ at $40^{\circ}C$ under pressure of 100 bar (sample 2), 120 bar (sample 3) or 150 bar (sample 4). We evaluated the antioxidant activities of the samples by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging, $Fe^{2+}$/ascorbate (FTC) and 2-thiobarbituric acid (TBA) methods. The antioxidant activities were examined by comparing the results with that of ascorbic acid as a positive control. Sample 3 showed relatively higher DPPH radical-scavenging activities than other samples. The antioxidant activity by FIC method exhibited similar results as the DPPH radical-scavenging activities. On the other hand, sample 2 showed higher antioxidant activity measured by TBA method of all. The whitening effects of the samples were examined using mushroom tyrosinase and B16F10 melanoma cells. Sample 3 exhibited overall significant whitening effects, however, other samples showed relatively lower effects. These results suggest that the peat moss extract purified by a supercritical 2 could be used as a cosmetic ingredient for the anti-aging and whitening effects.

  • Purpose: Fruit and vegetable juices are known to be rich sources of antioxidants, which have beneficial effects on diseases caused by oxidative stress. The purpose of this study was to directly compare the antioxidant activities of fruit and vegetable juices marketed in Korea. Methods: We analyzed four fruit juices, two vegetable juices, two yellow-green juices, and six mixed vegetable juices. Antioxidant activities were analyzed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) test, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonate) (ABTS) test, and oxygen radical absorbance capacity (ORAC) assay. Protective effects against DNA damage were determined using an ex vivo comet assay with human lymphocytes. Results: DPPH radical scavenging activities were in the following order: blueberry juice > mixed vegetable C juice > kale juice > mixed vegetable P juice > grape juice. ABTS radical scavenging activities were in the following order: blueberry juice > mixed vegetable C juice > grape juice > mixed vegetable P juice > kale juice. Peroxyl radical scavenging activities as assessed by ORAC assay were in the following order: blueberry juice > kale juice > mixed vegetable C juice > grape juice. Grape or blueberry juice showed strong abilities to prevent DNA damage in lymphocytes, and the difference between them was not significant according to the GSTM1/GSTT1 genotype. Conclusion: Antioxidant activities of fruit and vegetable juices and ex vivo DNA protective activity increased in the order of blueberry juice, grape juice, and kale juice, although the rankings were slightly different. Therefore, these juices rich in polyphenols and flavonoids deserve more attention for their high antioxidant capacity.

  • Objectives: Paeonia japonica has been widely used for gynecopathy and analgesic effects in Korean Traditional Medicine. The aim of the present study is to determine the antioxidant effect of Paeonia japonica extracts(PJE) by using mouse embryonic fibroblast cells(MEF cells). Methods: We evaluated Radical Scavenging Activity of PJE by the DPPH assay. Protective effect of the PJE on the hydrogen peroxide($H_2O_2$) induced oxidative damage of MEF cells was analyzed by the MTT assay. The Morphological changes of MEF cells induced by P. japonica, $H_2O_2$ and P. japonica+$H_2O_2$ was evaluated by DAPI staining. And effect of PJE on the rate of apoptosis in MEF cells was measured using flow cytometry with Annexin V-FITC and PI double staining. Results: We observed that PJE contain significant DPPH radical scavenging activity. Cell viability of oxidative damaged cells treated with various concentrations of $H_2O_2$ was increased by treatment with PJE. Flow cytometric analysis of the cells treated with $H_2O_2$ in the absence or presence of PJE showed that the crumbled G1 peak was accumulated by the treatment with $H_2O_2$ alone, but restored by addition of PJE. Portion of cells that undergo apoptosis mediated by oxidative stress was decreased by treatment of PJE. The nuclear fragmentation occurred in the oxidative damaged MEF cells was also decreased by PJE treatment. Conclusions: Taken together, our results suggest that PJE exhibits significant antioxidant activity and functions to inhibit cell death mediated by oxidative damage induced apoptotic pathways.
