      • Two new records of the genus Nola Leach, 1815 (Lepidoptera: Nolidae, Nolinae) from Laos

        Yeong–Bin Cha,Ulziijargal Bayarsaikhan,Sol–Moon Na,Dong–June Lee,Jae–Ho Ko,Tak–Gi Lee,Hyeong–Kyu Kim,Chang–Moon Jang,Han–Ul Kim,Yang–Seop Bae 한국응용곤충학회 2019 한국응용곤충학회 학술대회논문집 Vol.2019 No.04

        The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

      • 대호 간척기 토양의 염농도별 밭작물의 염해 평가

        이승헌,류순호,설수일,안열,정영상,이상모 江原大學校 附設 環境硏究所 2001 環境硏究 Vol.18 No.-

        This study was carried out to obtain the basic data for selecting the applicable crops in reclaimed land during desalinization period. A pot experiment was conducted with 5 different electrical conductivities of the saturated extracts (ECe 1, 3, 9, 14, and 16 dS·m^(-1)) of soils taken from the Dae-Ho reclaimed tidal lands. Eight crops (Chinese cabbage, radish, tomato, red pepper, buckwheat, soybean, sesame, and green perilla) were grown for 37days. Plant height and number of leaves were surveyed on 2 and 4 weeks after seeding, and on harvest time (5 weeks). After harvest, dry weights of harvested crops were measured and soil chemical properties were analyzed. Emergence rates of crops were comparatively high except sesame. For sesame, there was no emergence at ECe over 3 dS·m^(-1). Growth and dry weight decreased significantly as increasing ECe. The ECe which decreased 50% of dry weight index were 14.2 dS·m^(-1) for radish, 11.4 dS·m^(-1) for Chinese cabbage, 10.2 dS·m^(-1) for tomato for red pepper, 8.9 dS·m^(-1) for buckwheat and green perilla, 8.6 dS·m^(-1) for soybean, and 8.9 dS·m^(-1) for tomato. At higher ECe that start the growth inhibition, increasing 1 dS·m^(-1) in ECe, 7.7, 6.5, 5.9, 5.6, 5.2, and 4.9% of dry weight decreased for buckwheat, green perilla, Chinese cabbage, radish, soybean, and tomato (red pepper), respectively. The critical value of ECe for crop survival except sesame was 15.4~23.1 dS·m^(-1).

      • Antioxidant activity in vitro and mucosal protective effect of Rhei Rhizoma on reflux esophagitis induced in rats

        Ah Reum Lee,Yu Ock Shin,Joo Young Lee,Min Yeong Kim,Sung Ho Shin,Bu-Il Seo,Young-Bae Seo,Man Hee Rhee,TakakoYokozawa,Chan Hum Park,Seong-SooRoh 한국약용작물학회 2015 한국약용작물학술대회 발표집 Vol.2015 No.05

        Purpose Rhei Rhizoma (RR) is one of the herbal medicines traditionally used to treat diverse inflammatory diseases. The present study was undertaken to elucidate the antioxidant and anti-inflammatory activities of Rhei Rhizoma on experimental reflux esophagitis (RE) in rats. Methods The antioxidant activity of RR in vitro was measured in terms of radical scavenging capacity such as DPPH and ABTS. RE was produced by ligating both the pylorus and the transitional junction between the forestomach and the corpus. Rhei Rhizoma (125 and 250 mg/kg) were administered every day for 7 days, and its effect was estimated on comparison with RE control and normal rats. Results RR scavenged DPPH and ABTS effectively and IC50ofDPPH and ABTS radical scavenging activity of RR were 4.8 μg/ml and 15.75 μg/ml. The administration of RR decreased the elevated serum ROS in RE control rats. The RE control rats exhibited the down-regulation of antioxidant-related proteins such as Nrf2 and HO-1expression levels in the esophagitis; however, the level in the RR-treated RE rats was significantly higher than that in the RE control rats. Moreover, RE control rats exhibited the up-regulation of the protein expression related to oxidative stress at the esophagitis, but RR administration significantly reduced the expression of inflammatory proteins through the MAPK-independent signaling pathways. The expression of inflammatory mediators and cytokines by NF-κB activation was modulated through blocking the degradation of IκBα. In addition, the oral administration of RR regulated the gastric mucosal damage in RE rats. Conclusion The administration of Rhei Rhizoma effectively ameliorates the inflammatory damage of esophageal mucosa through radical scavenging activity and the activation of the Nrf2/HO-1 pathway.

      • Protective Effects of Hyperoside against Carbon Tetrachloride-Induced Liver Damage in Mice

        Choi, Jun-Ho,Kim, Dong-Wook,Yun, Nari,Choi, Jae-Sue,Islam, Md. Nurul,Kim, Yeong-Shik,Lee, Sun-Mee American Chemical Society and American Society of 2011 Journal of natural products Vol.74 No.5

        <P>In this study, the hepatoprotective effects of hyperoside (<B>1</B>), a flavonoid glycoside isolated from <I>Artemisia capillaris</I>, have been examined against carbon tetrachloride (CCl<SUB>4</SUB>)-induced liver injury. Mice were treated intraperitoneally with vehicle or <B>1</B> (50, 100, and 200 mg·kg<SUP>−1</SUP>) 30 min before and 2 h after CCl<SUB>4</SUB> (20 μL·kg<SUP>−1</SUP>) injection. Levels of serum aminotransferases were increased 24 h after CCl<SUB>4</SUB> injection, and these increases were attenuated by <B>1</B>. Histological analysis showed that <B>1</B> prevented portal inflammation, centrizonal necrosis, and Kupffer cell hyperplasia. Lipid peroxidation was increased and hepatic glutathione content was decreased significantly after CCl<SUB>4</SUB> treatment, and these changes were reduced by administration of <B>1</B>. Protein and mRNA expression of tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and heme oxygenase-1 (HO-1) and nuclear protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) significantly increased after CCl<SUB>4</SUB> injection. Compound <B>1</B> suppressed TNF-α, iNOS, and COX-2 protein and mRNA expression and augmented HO-1 protein and mRNA expression and Nrf2 nuclear protein expression. These results suggest that <B>1</B> has protective effects against CCl<SUB>4</SUB>-induced acute liver injury, and this protection is likely due to enhancement of the antioxidative defense system and suppression of the inflammatory response.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jnprdf/2011/jnprdf.2011.74.issue-5/np200001x/production/images/medium/np-2011-00001x_0006.gif'></P>

        Protective Effect of Baicalin Against Carbon Tetrachloride–Induced Acute Hepatic Injury in Mice

        Park, Sang-Won,Lee, Chan-Ho,Kim, Yeong Shik,Kang, Sam Sik,Jeon, Su Jin,Son, Kun Ho,Lee, Sun-Mee The Japanese Pharmacological Society 2008 JOURNAL OF PHARMACOLOGICAL SCIENCES Vol.106 No.1

        <P>This study examined the effects of baicalin, a bioactive flavonoid isolated from <I>Scutellariae Radix</I>, on carbon tetrachloride (CCl<SUB>4</SUB>)-induced liver injury. Mice were treated intraperitoneally with 0.5 ml/kg CCl<SUB>4</SUB> and different groups of animals received 25, 50, 100, and 200 mg/kg baicalin. At 24 h after the CCl<SUB>4</SUB> treatment, the level of serum aminotransferases and lipid peroxidation was significantly elevated, whereas the hepatic glutathione content was decreased. These changes were attenuated by baicalin. The histological studies showed that baicalin inhibited the portal inflammation, centrizonal necrosis, and Kupffer cell hyperplasia, which are the three most common characteristics of CCl<SUB>4</SUB>-induced liver damage. The serum level and mRNA expression of tumor necrosis factor-α were markedly increased by the CCl<SUB>4</SUB> treatment but suppressed by baicalin. The mRNA and protein expression levels of inducible nitric oxide synthase and heme oxygenase-1 increased significantly at 24 h after the CCl<SUB>4</SUB> treatment. Baicalin attenuated the increase in the protein and gene expression of inducible nitric oxide synthase but augmented the increase in those of heme oxygenase-1. These findings suggest that baicalin protects hepatocytes from the oxidative damage caused by CCl<SUB>4</SUB>, and this protection is likely due to the induction of HO-1 expression and the inhibition of the proinflammatory mediators.</P>

        치수 절단술 약제의 치수 섬유모세포에 대한 세포독성 연구

        이영희,이긍호 大韓小兒齒科學會 2000 大韓小兒齒科學會誌 Vol.27 No.1

        유치의 치수 절단술에 이용되는 약제들 (formaldehyde, formocresol, paraformaldehyde, ferric sulfate)이 농도 변화에 따라 치수 섬유모세포의 활성, 단백질 기질의 합성 및 무기질 침착에 미치는 영향을 규명하고자, 각각 0.01, 0.05, 0.10, 0.25, 0.50, 1.00㎕/㎖의 농도로 사람의 치수 섬유모세포에 24시간 적용시킨 후 세포활성검사와 함께, 조직의 재생과정 중 유기질이 되는 단백질의 합성능과 무기질 침착에 관여하는 알칼리성 인산효소의 활성에 미치는 영향을 완충액만을 투여한 대조군과 비교 평가한 결과 다음과 같은 결론을 얻었다. 치수 절단술 약제를 첨가한 후 24시간 배양하였을 때, formaldehyde, formocresol, paraformaldehyde 등의 경우 약제 농도가 증가함에 따라 대조군에 비하여 치수 섬유모세포의 세포활성이 크게 저하되었으며, ferric sulfate를 이용한 경우에는 세포활성이 유지되거나 약간 촉진되었다. formaldehyde, formocresol, paraformaldehyde 사이의 세포활성간에는 유의성 있는 차이가 보여지지 않았다. 치수 절단술 약제 첨가 후 배양액내의 총단백질양에는 큰 변화가 없었으나, paraformaldehyde에 의해 총단백질양이 약간 감소하였다. 약제 첨가 후 세포내의 단백질양을 측정하였을 때 ferric sulfate의 경우, 약제의 농도가 증가하였을 때도 지속적으로 단백질 합성이 저해됨을 알 수 있었다. formaldehyde, formocresol, paraformaldehyde, ferric sulfate는 치수 섬유모세포의 알칼리성 인산효소 활성을 약간 저해하였다. The effect of concentration as factor in cytotoxicity, protein synthesis and alkaline phosphatase activity was compared for pulpotomy medicaments (formaldehyde, formocresol. paraformaldehyde, ferric sulfate). Human pulp fibroblasts were exposed to a range of concentrations(0.01, 0.05,0.10, 0.25,0.50, 1.00㎕/㎖) of each agents, for period of 24hrs. The cell activities were evaluated by MTT assay, protein assay and alkaline phosphatase activity examination. The results as follows: 1. After 24hrs culture, pulp fibroblasts adding formaldehyde, formocresol and paraformaldehyde were suppressed cell activities with concentration increasing, but, no depression of cell activities by sulfate. No significant difference was in formaldehyde, formocresol and paraformaledhyde. 2. Protein synthesis by pulpotomy agents were not significant difference in pulp fibreblasts but protein synthesis were a little decreased by paraformaldehyde. 3. Alkaline phosphatase activity was a little decreased by pulpotomy medicaments.

        교정용 광중합형 및 화학중합형 레진접착제의 전단결합강도와 파절양상에 대한 연구

        이민화,박영준,양규호 大韓小兒齒科學會 1996 大韓小兒齒科學會誌 Vol.23 No.2

        Light-cured orthodotic composite resin has been widely advertised recently for use in bonding brackets.However,the curability of light-cured resin waves are diffused through metal brackets in questionable. The purposes of this study were to evaluate shear bond strenght and failure patterns of visible light-cured resin(Lightbond) and chemically cured-resin(Mono-Lok 2),and to determine the relative value of light-cured resin as an alternative to conventional chemically cured resin.Each of the two resins was tested on twently extracted human first premolars.Standard edgewise mental brackets were bonded to the teeth in accordance with the manufacturers' recommendation.After bonding,the teeth were stored for 24 hours at 37℃,100% huminity.The shear bond strenght was tested with a universal testing machine(Instron 4302),at 0.5mm/min crosshead speed.After debonding,brackets and enamel surfaces were examines with a scanning electron microscope and a stereoscopic microscope. The results were as follows: 1.Mental brackets bonded with Lightbond showed statistically highershear bond strenght than mental brackets bonded with Mono-Lok 2. 2.The predominant failure site in Lightbond was the enamel-resin interface,and in Mono-Lok 2 it was the resin itself. 3.Enamel cracks were not found in any specimen. The above results suggest that direct bonding of metal brackets enamel with light-cured resin bonding agent can be used effectively in clinics.

        다발성 무치근 치아에 대한 치과적 처치

        이미숙,이긍호,최영철 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.2

        감각신경아세포종으로 생후 1년 6개월부터 약 1년간 6주기의 화학요법과 생후 1년 6개월에 29회에 걸친 방사선 조사(AP 4540 R+LAT 1080 R : total 5620 R)를 받은 후 후유증으로 상악치아 및 상악골의 발육장애를 보이는 10세 남아의 임상적, 방사선학적 관찰 및 치료 후 다음과 같은 지견을 얻었기에 보고하는 바이다. 1. 성장중인 어린이에서 악성종양의 치료를 위한 방사선 조사는 연조직 및 경조직(골, 연골, 치아)등의 성장장애를 유발할 수 있으므로 시술 전 충분한 고려가 필요하다. 2. 치배의 손상은 치관 및 치근의 형성장애를 유발하고 이에 따라 치조골의 성장장애가 나타나므로 치근이 없는 치아일지라도 치조골의 흡수를 억제하기 위하여 hawley type의 부분의치 등을 이용하여 잔존시켜야 한다. 3. 향후 성장이 완료된 이후(만 18세 이상)에 무치근 치아 및 무치악 부위에 틀니(denture)나 임플란트 등의 보철수복이 필요할 것으로 여겨진다. Chemotherapy and radiotherapy used on pediatric oncology patients often causes dentofacial anomalies. Defects noted include tooth and root agenesis, root thinning, root shortening, localized enamel defect and maxillofacial underdevelopment. The effect of radiotherapy usually is confined to the radiation site but the effect of chemotherapy may be more wide spread becuase of its systemic distribution. Many pediatric cancers are treated with a combination of radiation and multiagent chemotherapy. Dental treatment affected by chemotherapy and radiation therapy damate to developing teeth and maxilloface includes retention of teeth, space maintenance, prosthetic considerations, requirements for oral hygiene. The following case related to multiple rootless teeth.
