Antioxidant activity of Cinchona officinalis stem bark extracts

MN, Ravishankara,Padh, Harish,M., Rajani Kyung Hee Oriental Medicine Research Center 2003 Oriental pharmacy and experimental medicine Vol.3 No.4

Stem bark of Cinchona sp. (Rubiaceae) is one of the well known drugs for its therapeutic values in traditional as well as modern medicine. Even though a lot of work has been carried out on quinoline alkaloids of Cinchona, its phenolic constituents received very little attention. In the present study, we evaluated antioxidant properties of C. officinalis stem bark methanolic extract and water extract containing phenolic compounds (total phenolics 21.37, 5.18% w/w respectively in the two extracts) in different in vitro and ex vivo models viz., antiradical activity by DPPH reduction, superoxide radical scavenging activity in riboflavin/light/NBT system, nitric oxide radical scavenging activity in sodium nitroprusside/Greiss reagent system and inhibition of lipid peroxidation induced by iron-ADP-ascorbate in liver homogenate and haemolysis of erythrocytes induced by phenylhydrazine in erythrocyte membrane stabilization study. Both the extracts exhibited very good antioxidant activity in all the models tested. The phenolic compounds including tannins present in the stem bark seem to offer protection from the oxidative damage.

Nuryasman MN 대한산업공학회 2021 Industrial Engineeering & Management Systems Vol.20 No.3

This study aims to determine the effect of inflation, the Dollar index, world oil prices, the Dow Jones index, and the economic crisis on the price of gold in the derivatives market. The study period is from January 2003 to December 2020. The research finds that the best model used in predicting gold price is Threshold Autoregressive Conditional Heteroscedasticity (TARCH)(1,2,2) with the lowest Akaike Information Criterion (AIC) value compared to other models and the value of Goodness of Fit highest from 3 other selected models. All independent variables are found to affect the price of gold. The study also found a variant of the gold price determined by the variant as well as the residual price of gold in the previous period. Another interesting finding is that volatility in gold prices has an asymmetric effect on the market. Inflation is statistically significant in weakening the effect of world oil prices on gold prices.

Thermal tolerance mechanism of invasive cotton mealybug parasitoid, Aenasius arizonensis Girault (Hemiptera: Encyrtidae)

Thimmegowda MN.,Suresh Suroshe Sachin,Sagar D. 한국응용곤충학회 2024 Journal of Asia-Pacific Entomology Vol.27 No.1

The sustainability and fitness of biocontrol agents depends on the abiotic factors of which temperature is the most critical factor. Thermal stress affects parasitoid behavior owing to change in physiological activities. So, an experiment was conducted to know the effect of thermal stress on the antioxidant enzymes in Aenasius arizonensis (Girault), a specific parasitoid of cotton mealybug, Phenacoccus solenopsis (Tinsley). Enzyme activity in P. solenopsis and A. arizonensis at each thermal stress treatment was noticed. At 3 h of thermal stress, the tem perature dependent increase in the SOD activity was observed. The maximum activity was noticed at 41 ◦ C in both P. solenopsis and A. arizonensis compared to the 27 ◦ C. The SOD activity was found more in four hours exposure compared to the three hours exposure at all the temperature treatments. Catalase activity was also found to increase with the increase in temperature, the effect of thermal stress was found to be significant in A. arizonensis and P. solenopsis for the activity of catalase. The maximum GST activity was found at 41 ◦ C for both P. solenopsis nymphs and A. arizonensis adults exposed to different temperature treatments for 3 h of duration. However, all the temperature treatments for P. solenopsis nymphs were non-significant, whereas, for A. arizonensis, it was found significant for the GST activity. We observed that thermal stress had no effect on the concentration of MDA in both P. solenopsis and A. arizonensis subjected to different durations of temperature regimes. Elevated levels of SOD, CAT and GST might be providing possible protection against reactive oxygen species generated under elevated thermal stress.

대학 브랜드 아이덴티티를 고려한 강원대학교 교문 디자인에 관한 연구

김민규 ( Mn Gyu Kim ) 한국기초조형학회 2012 기초조형학연구 Vol.13 No.3

근래 들어 건물이나 조형물의 시각적 이미지가 그 집단이 추구하는 가치를 구성원끼리 공유하게 하며, 외부로 표현하는 의미로 인식되면서 그 중요성이 부각되고 있다. 대학의 교문은 영역의 구분과 출입구의 역할의 기본적 기능을 넘어서 대학의 입구성과 상징성을 표현하는 중요한 디자인 대상이다. 문은 출입을 위한 건물의 기본적 요소라는 의미이외에 건물의 성격과 입구를 상징하는 요소이다. 본 연구에서는 대학의 이미지에 가장 큰 영향을 미치는 요소 중에 대학교문의 디자인 요소 및 조형성에 대하여 조사, 분석하여 대학교문의 의미를 고찰하고, 실제 대학 캠퍼스를 대상으로 대학 교문의 디자인을 제시함으로서 교문의 디자인 프로세스와 컨셉 구성의 예를 제시하고자 하였다. 본 연구를 통해 대학교문 설계 시 다음과 같은 디자인 고려사항과 전략이 필요할 것이다. 첫째, 대학교문은 문은 출입이라는 기능적 의미 이외에 입구성, 장소성, 고유성의 특성을 표현해야 한다. 둘째, 대학교문은 유개형과 무개형으로 나눌 수 있는데, 대학교문의 대지의 제약점, 기능적 목적, 조형적 목적에 의해 형태를 결정지어야 한다. 셋째, 대학교문의 디자인 요소는 교문의 형태이외의 문주의 슬롯형태, 문주의 조형성의 변화, 문주의 재료 변화 등이 있다. 대학 교문의 조형성은 단순한 미적 기준만을 충족해서는 안될 것이며, 입구성과 대학의 이념과 지역의 고유성 등의 복합적인 의미를 창출해야한다. 이러한 통찰적인 디자인 요소가 고려된다면, 대학 교문은 대학의 이미지 상승과 시각이미지를 통해 학생들이 대학의 이념을 공유하는 대학 브랜드 아이덴티티의 역할을 수행할 수 있을 것이다. Recently expressing the image of organizations by representative object such as company identity or building skin design has become more generalized and the importance of identity design has increased considerably. A university gate of shall be considered same way. It is not just an entrance or boundary for the campus. It is an important design object that represents the symbolic image of university. That means a university gate needs to meet functional and symbolic requirement also it is a formative element as well as an architectural element. The purpose of this study is to inspect the meaning of University gate by analyzing design factors and formations which influence the campus identity most and to propose a case study of concept design process applied to an actual university gate design. According to this study three design strategy is to be considered for a university gate design. First, visual emphasis of entrance and exit, uniqueness and placeness to be expressed. Second, gate design can be categorized into opening types and column types. Those types depend on the context, function and formativeness. For instance, opening type with four pillars or "h" shape is suitable for separation of pedestrian and vehicle. Third, There are three important design elements for a university gate. patterns of slotted tiles, formativeness and material. A university gate should create multiple meanings such as placeness, locality and campus identity as well as satisfying the aesthetic value. When these design strategies were considered properly a university gate will perform a role of representing the campus that shares the principles of students and university through the visual image of it.

프랑스에서 한의학의 보급과 제도화 과정 : 침술의 경우

김민호,Kim, Mn-Ho 대한예방한의학회 2010 대한예방한의학회지 Vol.14 No.1

The aim of this study is to observe the spread and implementation of acupuncture as an official medical treatment in France. This research is based on the study of the scientific magazine produced by the Association of Acupuncturist Doctors of France from 1945 to 2008 as well as medical and sociological studies. Western medicine was introduced and spread in Korea about one hundred years ago and is the foundation of modern Korean medicine. Nowadays it is more commonly employed than traditional Oriental medicine. Oriental medicine was introduced in France in the 17th century but only acupuncture gained notoriety. The French Faculty of Medicine officially chose to legalize acupuncture after WWII but only allowed doctors to study acupuncture. It takes three years to obtain an Inter-University Degree(DIU) in acupuncture therapy. Why would the Faculty of Medicine make a holistic treatment system official that is in opposition to the systematic treatment method of the Western medicine? The second question posed is, does Western Academia still recognize acupuncture as a viable treatment method? The final question addressed is, has acupuncture any real impact on medical treatment of the French Society?
