Kidney stones occur in approximately 1% of the population during their lifetime. Although the development of extracorporeal shock wave lithotripsy (SWL) has revolutionized the theraphy of urolithiasis, the rate of recurrence of urothiasis, the rate of recurrenece of stones after SWL is about 50% within 10 years, which still represents serious problems for patienes. So to clarify the mechanism of Urocalum, and QS (Quercus salicina Blume) extract in the treatment of urolithiasis. Rat calcium oxalate urolithiasis was induced by oral administration of ethylene glycol and the vitamin D3 analog alfacalcidol for 14 days and QS extract was given to rats. After the last administration, we measured in urine, serum and renal oxidative stress marker. Ethylene glycol and alfacalcidol treatment increased BUN, creatinine, uric acid and XO. This increase was significantly suppressed by the administration of QS extract. These finding suggest that the QS extract plays a role in the prevention of stone formation and recureence in urolithiasis.

DOI : 10.7732/kjpr.2012.25.5.517
This study was conducted to investigate the morphological and anatomical characteristics of needle and the genetic diversity of Pinus pumila Regel which is a unique and the southern peripheral population in South Korea. ANOVA test showed that there were significant differences among individuals within population in all 8 needle characteristics. Average characteristics of 66 individuals were 53.59 mm in needle length, 0.78 mm in needle width, 68.98 in needle index, 0.65 mm in needle thickness, 4.56 ea. in maximum stomata row, 3.80 ea. in minimum stomata row, 8.36 ea. in total stomata row and 1.71 ea. in resin canals, respectively. Resin canal per needle of this species ranged from one to three, depending on external type. Especially, arrangement types were 69.47% in two resin canals and 30.45% in a single resin canal. A total of 78 bands was generated from 9 selected I-SSR primers. The estimates of genetic variation were 61.5% in proportion of polymorphic bands (P), 1.698 in effective number of alleles (
), 0.388 in expected heterozygosity (
) and 0.567 in Shannon's information index (S.I.), respectively.

This study was carried out to clarify the regional folk plants in the southern inland area of Gyeonggi-do Province. According to the survey results, derived from 1,229 sheets of 90 residents at 35 places from 9 counties and cities between October 2009 and December 2010, the folk plants in the inland southern area of Gyeonggi-do consisted of a total of 259 taxa; 82 families, 200 genera, 221 species, 4 subspecies, 32 varieties, and 2 forma. The classification of the plants by its usage was; 214 as edible, 119 as medicinal, 34 as ornamental, 18 as timber, 12 as dye, 5 as oil, 3 as spice, 2 as fiber, 2 as aroma, and 22 as others uses. So, the edible and medicinal uses are higher than other uses. The most useful part was the leaf, followed by fruit, stem, root, and flower. The collection season was focused on spring and summer, because the leaf was mainly collected in an edible condition during those seasons. Traditional knowledge of folk plants was mostly passed down orally. The consistency comparison between the standard common name and the local name was the highest in the people in 50s and the lowest in those in 80s.

To gather the basic data for increasing the utilization of Isatis tinctoria, we examined the effects of both antioxidative enzyme activity and antimicrobial activity from the extract of Isatis tinctoria. Ascorbate Peroxidase activities reveal that there is an decrease in order; ethanol extract from its stem (1601.7 Unit/mg protein), methanol extract from its leaf (1133.7 Unit/mg protein) and distilled water extract from its leaf (524.3 Unit/mg protein). Catalase activities reveal that there is an decrease in order; ethanol extract from its flower petal (177.1 Unit/mg protein), methanol extract from its leaf (120.8 Unit/mg protein) and distilled water extract from its flower petal (55.4 Unit/mg protein). Peroxidase activities reveal that there is an decrease in order; ethanol extract from its flower petal (27.1 Unit/mg protein), methanol extract from its flower petal (14.6 Unit/mg protein) and distilled water extract from its stem (10.4 Unit/mg protein). Superoxide dismutase activities reveal that there is an increase in order; distilled water extract from its root (90.8%), methanol extract from its flower petal (80.1%) and ethanol extract from its root (75.5%). Its flower extract showed a antimicrobial activity only against Vibrio parahaemolyticus, its root extract had only against Staphylococcus aureus, and its stem extract had against Bacillus subtilis, Escherichia coli and Staphylococcus aureus, regardless of solvents. Especially, distilled water extract from its leaf showed a high antimicrobial activity against both Bacillus subtilis and Escherichia coli and inhibition diameters against those were 30.0 and 24.0 mm, respectively.

DOI : 10.7732/kjpr.2012.25.5.550
The aim of this study is to research spatial diffusion, a condition for spread of Ailanthus altissima, and conduct flora analysis to provide useful information for management of it. Three research spots where the community dominance value was found to be high and habitat was homogeneous according to a 2010 in-depth species study were selected, and census was conducted using a line-transect method. The diffusion area included 1,435
in Yangpyeong, 1,118
in Gimcheon and 760
in Sancheong, in order of increasing size, and a total of 510 trees were found to be randomly diffused in space. An average of 83.2% of Ailanthus altissima were found to be included in DBH classes I (1.0-3.4 cm) and II (3.5-6.4 cm), showing that young trees were dominant in Ailanthus altissima communities and there was an age diffusion pattern according to degree of disturbance in habitats. A total of 41 families 75 genera and 91 species of flora made up the list, and Therophytes were most widely found in all of the three areas. This shows that habitats in these areas have recently been disturbed. It was evaluated that elimination of roadside population and mountainous area population was necessary to prevent diffusion of Ailanthus altissima.
Study on the Immunomodulatory Effects of Ellagic Acid and their Mechanisms Related to Toll-like Receptor 4 in Macrophages
NamKoong, Seung ; Kim, Ye-Jin ; Kim, Taeseong ; Sohn, Eun-Hwa ;

Ellagic acid (EA) is a phenolic compound in fruits and nuts including raspberries, strawberries, grapes and walnuts. Previous studies have indicated that EA possesses antioxidant activity, growth-inhibition and apoptosis-promoting activity in cancer cells. However, macrophage mediated cytotoxicity and immunomodulating effects on cancer cells have not been clarified. In the present study, we show that EA increased effects on macrophage mediated tumoricidal activity and NO production without direct tumor cell cytotoxicity. To further determine whether TLR4 (toll like receptor 4) is involved in anti-tumor activity, cells were treated TLR4 signaling inhibitor, CLI-095 in the presence of EA. CLI-095 treatment partially reduced macrophage-mediated tumoridial activity. EA also has inhibitory effects of NO production induced by LPS, whereas phagocytic activity was not changed. These results suggest that EA induces macrophage mediated tumoricidal activity which is partially related to TLR4 signaling and has a potential adjuvant in cancer therapy.

DOI : 10.7732/kjpr.2012.25.5.568
The objective of this study was to investigate the antioxidative capacity of ethanol extracts from Rumex crispus L. The concentration of R. crispus L. extract at which DPPH radical scavenging activity was inhibited by 50% was 2.15 mg/mL, which was lower than that of
-tocopherol (0.43 mg/mL), as compared to 100% by pyrogallol as a reference. Total antioxidant status was examined by total antioxidant capacity against ABTS radical reactions. Total antioxidant capacities of R. crispus L. extract at concentrations of 0.1 and 1 mg/mL were 0.47 and 2.33 mM Trolox equivalents, respectively, which were higher than those of
-tocopherol. Superoxide scavenging activities of R. crispus L. extract at concentrations of 0.1 and 1 mg/mL were 21.5 and 78.9%, respectively, which were not significantly (p>0.05) different from those of catechin. Oxygen radical absorbance capacities of R. crispus L. extract at concentrations of 20 and 100
were 62.5 and 156.4
Trolox equivalents, respectively, which were lower than those of ascorbic acid. Cupric reducing antioxidant capacities of R. crispus L. extract at concentrations of 0.1 and 1 mg/mL were 0.28 and 1.88 mM Trolox equivalents, which were similar or significantly (p<0.05) higher than those of
-tocopherol, respectively. R. crispus L. extract prevented supercoiled DNA strand breakage induced by hydroxyl radical and peroxyl radical. Total phenolic contents of R. crispus L. extract at concentrations of 0.5 and 5 mg/mL were 0.58 and 3.85 mM gallic acid equivalents, respectively. R. crispus L. extract at concentration of 0.1 and 0.5 mg/mL inhibited 0.2 mM tert-butyl hydroperoxide-induced cytotoxicity by 38.5 and 63.5%, respectively, in HepG2 cell culture system. Thus, strong antioxidant and cytotoxicity-inhibiting effects of R. crispus L. extract seem to be due to, at least in part, the prevention from free radicals-induced oxidation as well as high levels in total phenolic contents.

Cytokines released from innate immune cells play key roles in the regulation of the immune response. Red Ginseng (RG, steamed and dried root of Panax ginseng C.A. Meyer) is known to show different pharmacological effects by changed composition of saponins compared with Panax Ginseng. In this study, we examined the immunomodulatory effects of RG on the regulation of cytokine release in mice. RG was injected i.p at doses of 0.5, 5 and 50 mg/kg for 6 weeks. We assessed that the weight index of immune organs such as thymus, and spleen, and the mitogen blastogenesis of splenocytes. We also determined the levels of circulating cytokines in serum from RG-treated mice using ELISA assay. The weight index of thymus and spleen, and proliferation of mitogen response of splenocytes have increased in the RG-injected groups. In addition, the levels of IFN-
, IL-6, IL-12 and IL-2 concentrations have significantly increased in the serum of RG-treated mice, but that of IL-10 has not. These results suggest that RG has immune stimulating effects and could be useful as a immunoregulator of circulating cytokine release in vivo.

This study was conducted to investigate the seedling cultivation methods of Ostericum praeteritum Kitag. The results are as follows ; Ostericum praeteritum transplanted from wild seedlings and seedling cultured in the open field grew quite well, but their bolting rate was higher than other seedlings resulting in low root production. Seedling cultured in tray pot of green house produced good quality root as 426 kg/10a indicating the most adequate seedling method for Ostericum praeteritum production. Main compounds of Ostericum praeteritum roots were found as oxypeucedanin and bisabolangelone, and contents of wild seedlings were lower than theirs of the other seedlings methods.

DOI : 10.7732/kjpr.2012.25.5.591
This study was conducted to investigate the possibility of changes in onion (cv. 'Turbo' and 'Changnyongdaego') bulb quality during storage at room and cold temperature. Increased weight loss was found in the onion bulb stored at both cold and room temperature conditions. 4% weight loss was found in bulbs stored at room temperature and 2% at cold storage as compared to fresh cultivated onion bulb; after three months. Initially, there was no significant difference in the firmness of bulbs between cultivars and storage conditions. Hunter a value of bulb stored at room temperature was higher than the value of bulb stored at cold temperature. 27% and 7.9% decay was found after three months in 'Changnyongdaego' and 'Turbo' cultivars stored under room temperature condition respectively. In contrast, only 2% decay was noticed in both cultivars stored at cold storage condition. Hunter L value of onion bulb gradually decreased in both room and cold temperature storage conditions. In conclusion, quality of onion bulb can be maintained until three months. For long term storage and quality maintenance, under room temperature conditions a resistance cultivar should be selected.

As there have been lately many worldwide resource challenges such as potential exhaustion of fossil fuels, sudden rise of oil price and ever-rising grain pricing due to global food crisis, there have been more interests focused on recycling vegetable oils and fats into clean natural fuel and producing new resources based on waste cooking oil as a part of reusing waste resources. An Experiment was performed by using ratio of 50:50, 75:25 (w/w) mixture of based rapeseed oil, camellia oil, and olive oil. 50:50, 25:75 (w/w) mixture of based palm oil. The result was that the oleic acid (
) got the lowest percentage of 42.8%, when we combined the mixture of rapeseed oil and soybean oil. While the highest percentage of 72.1% was when the mixture of camellia oil and rapeseed oil were combined at 50:50 ratio. In 75:25 (w/w) case, mixture of rapeseed oil and soybean oil got the lowest. The highest ratio was the mixture of camellia oil and olive oil. Based on the component of palm oil, the total saturated fatty acid was decreased. It is expected that stabilizing oxidation through controlling of fatty acid after mixture and that liquidity at a low temperature. The acid value indicated that stabilizing oxidation got a range of highest to lowest. Camellia oil ranked as the highest, followed by olive oil, and the oil seeds as the lowest in rank. Controlling iodine value through mixture and improvement of stabilizing oxidation will provide a good quality. The quality of color has no significant change about mixture in ratio and maintenance. The reduction of the cost of refining process is expected by controling of mixture ratio at biodiesel production in the future.

This study was performed to evaluate the effect of ethanolic extract from the fruit of Empetrum nigrum var. japonicum (EN) on
-induced hepatotoxicity. Orally provided daily for 7 days were 250-mg/kg or 500-mg/kg EN or vehicle, while
(40 mg/kg) was intraperitoneally injected the day after the last treatment of EN. Twenty-four hours after injection of
, we measured serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, malondialdehyde (MDA) contents, superoxide dismutase (SOD), and catalase (CAT) activity of the liver. The antioxidant activities were measured with the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and inhibitory effect on lipid peroxidation. The EN showed a strong DPPH radical scavenging activity and inhibitory effect of lipid peroxidation. The ALT and AST levels in serum were greatly enhanced by the
injection. However, in the EN treatment group, the levels of ALT and AST in serum were significantly reduced. Moreover,
significantly increased the MDA contents and decreased the SOD and CAT activity in liver homogenates. The EN recovered MDA contents, close to that in the normal group, while the EN increased the SOD and CAT activity. These results suggest that ethanolic extract from the fruit of Empetrum nigrum var. japonicum has significant antioxidant activity and hepatic protection potential.

DOI : 10.7732/kjpr.2012.25.5.652
'Blue Edge' (Hosta minor) was induced by ethyle methane sulfonate (EMS) to obtain mutants. Among induced leaf variegated hosta plants, some with deep-green color pattern on the edge of the leaves was selected. They were cultivated via vegetative propagation. Assessment of botanical characteristics was conducted for three years since 2003. The major characteristic of these cultivars is that they maintain their deep-green color on the edge of the leaves all year round. These cultivars are useful as materials for pot plant or as ground cover plant.
