이미향,김미숙,장창수,김철환 大韓顎顔面成形再建外科學會 1996 Maxillofacial Plastic Reconstructive Surgery Vol.18 No.2

Osteochondroma is a common benign tumor of the axial skeleton, especially the distal metaphysis of the femur and the proximal metaphysis of the tibia, however, is occurred rarely in the facial skeleton. Development of the tumor is most frequently seen in the second or third decades of life. Typically, it arises directly from the cortex of the underlying bone, without any intervening zone of abnormal osseous tissue, and is covered by a cap composed of cartilage undergoing calcification. In case of osteochondroma of the mandibular condyle, its clinical features are occulusal change, facial asymmetry, headache, pain and click on temporomandibular joint, mouth opening limitation, and jaw deviation to involved site. This is a case report of a 13-year old woman who had mouth opening limitation and severe temporomandibular joint pain. We obtained successful results with surgical removal of the osteochondroma on the mandibular condyle.

The polymerase chain reaction (PCR) was used for detection of human papillomavirus (HPV) in paraffin-embedded tissue. Tissues stored as paraffin blocks were a potential source of DNA for retrospective clinicogenetic analysis. Sections in 6 ㎛ (three or five) thick cut from paraffin blocks of 29 uterine cervix dysplasia, 34 uterine cervix carcinoma in situ, 42 uterine cervix squamous cell carcinoma and 10 uterine cervix metaplasia samples were deparaffinized and incubated at 37℃ for 48hrs. in the lysis solution. Following organic extraction and alcohol precipitation, and extracted DNAs were identified by gel electrophoresis. These DNAs carried out PCR. After repeated cycles of specific oligonucleotideprimed extension of viral DNA with thermophilic DNA polymerase. the type of HPV present was then determined on the basis of the size of the ethidium-bromide stained band visible after agarose gel electrophoresis : for HPV 6 is 263 bp. for HPV 11 is 144 bp, for HPV 16 is 601 bp. and for HPV 18 is 360 bp. This study detected HPV DNA in four cases. which broke down to HPV 16 in two case of uterine cervix carcinoma in situ and two case of uterine cervix squamous cell carcinoma, no HPV type in the remainder. Histologically, HPV types 6, 11 are mainly detected in benign genital warts and lowgrade cervical dysplasias, squamous cell carcinoma frequently contained HPV 16, whereas, HPV 18 was present in adenocarcinoma, adenosquamous cell carcinoma and small cell carcinoma of the cervix. These results indicate that cervical cancers might be clinically influenced by the differences in sutible of the infecting HPV.

황옥철,장미향 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.4

This research is for contemplating what Athleticism and Amateurism devote the meaning to the cultural development of England Sports. For this study, I have been researching the formation of England Sports, the concept of Athleticism, the education of England and the idea of Amateurism, Elite Education and the Spirit of Olympic as well as taken lead in what Amateurism gives the significance to England Sports. By doing this, the result of the study contents through the method of literature consideration produces the following conclusions. Firstly, Athleticism of England society is an ideology related to the characteristic educational system of England. It has been developing the circular cause and effect of Elite Group on a basis, and existing the heart of England Sports Systematization. Secondly, Athleticism which has promoted the systematization and spread of England Sports is established as a sports Ideology that is shrine connected with moral, religious, political purposes, a solemn Christian and pursuing cultivation of imperialistic loyalty. Thirdly, Amateurism which cannot be paid in a material way through the Sports in the middle and high classes is an Ideology that adopted by Coubertin, Pierre de as a general spirit of Olympic and contributes to the spread of England Sports and even significantly the change of educational ideology of Sports. Fourthly, Athleticism and Amateurism which is an central ideology systematization and spread of England Sports Culture have enormously influence on the formation of Sports improvement and modern Sports in England, have offered the significant points of world athletics and sport culture development.

Polygoum Tinctoria와 합성 인디고 염료의 물리화학적 특성 비교

최창용,장미경,공병기,최혜영,나상권,이동병,양숙향,나재운 한국공업화학회 2002 응용화학 Vol.6 No.2

The natural dye substances appear to have a lot of benefits that enable the dyed materials to exhibit their natural colors. It may have a bit of a harmful influence on the human body itself, in comparison with the synthetic substances. It also causes hardly any environmental pollution because of the natural chemicals and costs much less to disposal. In this study was investigated physicochemical characterization of polygoum tinctoria dye substance and synthetic indigo. Calcium hydroxide was added into polygoum tinctoria leaves to precipitate dye substances and it was freezing dried into powder form. Characterizations of dye substances were investigated by UV/VIS spectrophotometer, TLC, DSC, TGA, HPLC, and MALDI-TOF Mass. Resultantly, polygoum tinctoria was confirmed that is consisted of two ingredients from these results.

Glycyrrhiza uralensis계의 원감초 뿌리에서 추출도는 감초는 여러가지 질병의 약제로 널리 이용되어 왔다. 그 주성분인 gliycyrrhizin은 항염증 활성 및 anti-allergic activity를 갖고 있으며 이러한 생리활성은 aglycone β-gliycyrrhetinic acid 의 활성에 의한 것으로 알려져 있고, β-gliycyrrhetinic acid는 steroid 구조와 유사하며, 면역조절 특성을 갖는 것으로 인식되고 있다. 이러한 β-gliycyrrhetinic acid 의 면역조절 활성에 기여하는 인자와 그 경로에 대하여 조사된 바 있다 Glycyrrhizin은 감초뿌리의 주성분중 하나이며, 그외에도 surgars(14%), starches(30%), flavonoids, saponoids, amonoacids, gums 및 essential oil 등을 포함하고 있다. Licorice, the root extract of Glycyrrhiza uralensis, is used as a medicine for various diseases. Antiinflammatory as well as anti-allergic activities have been attributed to one of its main constituents, glycyrrhizin. These activities are mainly ascribed to the action of the aglycome β-glycyrrhetinic acid. βGlyeyrrhetinic acid has a steroid-like structure and is believed to have immunomodulatory properties, To determine whether interference with complement functions may contribute to the immunomdulatory activity of β-glycyrrbetinic acid. its effect on the classical and alternative activation pathways of human complement were investigated. The main constituent found in the root is glycyrrhizin. The plant also contains various sugars(14%), starches(30%), flavonoids, saponoids, aminoacids, gums, and essential oil etc.

<P> Polymorphonuclear leukocytes (PMNs) play an important role in myocardial ischemia/reperfusion (MI/R) injury. Moreover, platelets are also important blood cells that can aggravate myocardial ischemic injury. This study was designed to test the effects of PMNs and platelets separately and together in provoking cardiac dysfunction in isolated perfused rat hearts following ischemia and reperfusion. Additional control rat hearts were perfused with 75⁓10<SUP>6</SUP> PMNs, with 75⁓10<SUP>6</SUP> platelets, or with 75⁓10<SUP>6</SUP> PMNs⁢75⁓10<SUP>6</SUP> platelets over a five minute perfusion followed by a 75 min observation period. No significant reduction in coronary flow (CF), left ventricular developed pressure (LVDP), or the first derivative of LVDP (dP/dt max) was observed at the end of the observation period in any non-ischemic group. Similarly, global ischemia (I) for 20 min followed by 45 minutes of reperfusion (R) produced no sustained effects on the final recovery of any of these parameters in any group of hearts perfused in the absence of blood cells. However, I/R hearts perfused with either PMNs or platelets alone exhibited decreases in these variables of 5∼10% (p<0.05 from control). Furthermore, I/R hearts perfused with both PMNs and platelets exhibited decreases of 50 to 60% in all measurements of cardiac function (p<0.01). These dual cell perfused I/R hearts also exhibited marked increases in cardiac myeloperoxidase (MPO) activity indicating a significant PMN infiltration, and enhanced P-selectin expression on the coronary microvascular endothelium. All cardiaodynamic effects as well as PMN accumulation and P-selectin expression were markedly attenuated by a recombinant soluble PSGL-1 which inhibits selectin mediated cell adhesion. These results provide evidence that platelets and PMNs act synergistically in provoking post-reperfusion cardiac dysfunction, and that this may be largely due to cell to cell interactions mediated by P-selectin. These results also demonstrate that a recombinant soluble PSGL-1 reduces myocardial reperfusion injury by platelet and PMNs interaction.
