국내 사망률 가장 높은 비율을 차지하고 있는 惡性腫瘍에 대하여 국내외적으로 다양하게 연구되고 있다. 그러나 아직까지도 腫瘍을 치료하기 위하여 手術治療·放射線治療·免疫治療·化學治療등의 많은 치료법을 개발하고, 또한 실험실 및 임상에서 많은 연구보고가 이루어지고 있지만 腫瘍의 치료원칙 및 치료약물에 대해서 미흡한 것이 국내의 현실이다. 일반적으로 抗癌劑를 이용한 化學治療등이 사용되고 있지만 이에 따른 副作用이 많아 본 연구자들은 抗癌劑와 韓藥材를 倂用投與하여 副作用을 최소화하고, 이에 따라 韓藥材가 正常細胞에 어떠한 영향을 미치고 , 癌腫細胞에는 어떠한 영향을 미치는가에 대하여 관찰한 결과 有意性이 있어 보고하게 되었다. 淸熱作用이 金銀花와 魚腥草를 인체의 皮膚癌細胞인 A431 細胞, 子宮癌細胞인 HeLa 細胞, 急性白血病細胞인 MOLT-4 細胞, 慢性骨髓性白血病細胞인 K562 細胞에 대한 細胞毒性과 抗癌劑인 mitomycin C와 倂用처리결과를 MTT assay를 통하여 관찰하였다. 또한 正常細胞에 대한 細胞毒性을 검색하기 위하여 마우스 섬유아세포(Balb/c3T3), 마우스 胸線 및 腥臟細胞, human lymphocyte에 미치는 細胞毒性을 검토하였다. 魚腥草는 慢性骨髓性白血病細胞柱에 직접적인 細胞毒性을 나타냈고, mitomycin C와 倂用 處理時 細胞毒性을 증가시켰으며, 마우스 섬유아細胞인 Balb/c 3T3 細胞의 增殖을 억제시켰다. 또한 金銀花는 마우스 胸線細胞의 增殖을 촉진시켰고, human lymphocyte의 增殖을 촉진시켰으며, 金銀花 및 魚腥草 모두는 마우스 腥臟細胞의 增殖을 촉진시켰다. The purpose of this research was to investigate effect of water extract of Flos Lonicerae and Herba Houttuyniae on the proliferation of human cancer cell-lines. The effects of Flos Lonicerae and Herba Houttyniae on the proliferation of A431, HeLa, MOLT-4, K562 cells, Balb/c 3T3 cells, mouse thymocytes, splenocytes and human lymphocytes were estimated by MTT colorimetric assay. 1. Flos Lonicerae and Herba Houttuyniae inhibited the proliferation of K562 cells. 2. The cytotoxicity of mitomycin C on K562 cells was decreased by the combination of Herba Houttuyniae. 3. Herba Houttuyniae inhibited the proliferation of Balb/c 3T3 cells. 4. Flos Lonicerae stimulated the proliferation of thymocytes. 5. Flos Lonicerae and Herba Houttuyniae stimulated the proliferation of splenocytes. 6. Flos Lonicerae stimulated the proliferation of human lymphocytes.

The purpose of this study is to determine the effect of Semen Cuscutae on phenylephrine(PE) and KCI induced contraction of isolated rat thoracic aorta. Contractile force was measured with force displacement transducer under 1.5 g loading tension. Contraction evoked by PE (ED_(50)) was relaxed significantly by Semen Cuscutae. The mean percent relaxing of PE induced contraction was 60.6% (p<0.01) after 300 ㎕/㎖ Semen Cuscutae, but the mean percent contraction of KCI induced contraction was 10.4% (p<0.05) after 300 ㎕/㎖ Semen Cuscutae. Vasorelaxation by Semen Cuscutae was significantly reduced after with and without endothelial cells. Pretreatment of aortic rings with L-NAME (100 μM), a nitric oxide synthase inhibitor, indomethacin (3 μM), an inhibitor of cyclooxygenase, methylene blue (10 μM), guanylyl cyclase inhibitor, propranolol (1 μM), a β-adrenoceptor antagonist, atropine (1 μM), a muscarinic receptor antagonist and diltiazem (10 μM), a Ca^(2+)-channel blocker was recovered the effect aorta. These results indicate that Semen Cuscutae can relax EP induced contraction of isolated rat thoracic aorta and that this increasing contraction related to epithelium and various effect.

This paper shows the efficiency of fuzzy integral variable structure controller(FIVSC) with sliding mode which outperforms a traditional variable structure controller(VSC). This approach of the FIVSC solves the chattering problem which has been occurred in VSC and is applied to brushless D.C. motor. The simulation results verify the efficiency of the FIVSC.

벼葯培養에 있어서 低溫處理가 植物體分化에 미치는 影響

This experiment was studied to determine the effects of low temperature treatment on culturability in anther culture of Tongil type(Indica/Japonica) rice varieties. Three Japonica varieties have better reaction to callus induction and plant regeneration than those of Indica and Indica/Japonica varieties. The mean frequency of plant regeneration of three Indica/Japonica varieties was less than 1%. But the frequency of callus induction and plant regeneration of Milyang 23(Indica/Japonica) was showed the best result in the anthers pretreated at 12℃ for 20 days, the frequency of callus induction and plant regeneration was 31.6% and 13.6%, respectively. Most of calli derived from pretreated-anthers, above 90%, were induced from 20 to 35 days after anther inoculation. Combination of NAA, Kinetin and ABA showed the best result on the growth of callus induced from pretreated-anthers.

매복된 상악 중절치의 교정적 견인을 이용한 치험례 : CASE REPORT

김종식,김은정,김현정,남순현,김영진 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.1

치아 매복이란 여러 가지 이유로 구강 점막이나 악골내에서 치아가 맹출하지 못하고 있는 상태를 의미한다. 상악 중절치 매복의 원인은 치아종, 과잉치, 공간의 상실, 선행유치의 만기잔존 또는 조기상실, 선행유치의 외상으로 인한 치관이나 치근의 기형, 치배의 이소위치 등이 있다. 매복된 상악 중절치의 경우, 측절치가 빠르게 근심으로 이동하여 공간을 상실하고, 정중선의 변이가 발생하며, 낭종을 형성할 가능성도 있다. 따라서, 매복치의 조기 진단과 그에 따른 적절한 처치가 즉각적으로 이루어져야 한다. 일반적으로 매복의 정도가 심하지 않거나, 각화조직에 의해 매복이 초래된 경우 외과적인 노출만으로도 맹출을 유도할 수 있지만, 외과적인 노출후에 일정기간의 관찰에도 맹출이 되지 않는다거나, 치아의 맹출 방향이 자가 교정될수 없을 정도로 심하게 변위되어 있는 경우, 매복의 위치가 너무 심부에 있는 경우에는 교정적 견인을 시도하는 것이 바람직하다. 본 증례는 매복된 상악 중절치 중 일정기간의 주기적 관찰후 맹출이 기대되지 않았기에, 교정적으로 견인하여 치료하였으며, 치료후 다소의 지견을 얻었기에 보고하는 바이다. A tooth impaction means a state that a tooth does not erupt out of oral mucosa or alveolar bone for many reasons. The reasons for an impaction of the Maxillary central incisor are an odontoma, supernumerary tooth, space loss, prolonged remaining or early loss of a preceding deciduous tooth, abnormalities of crown or root caused by trauma of a deciduous tooth and an ectopic position of a tooth germ. In the case of the impacted maxillary incisor, a rapid mesial movement of a lateral incisor leads a space loss and a midline deviation can be happened. Furthermore, it can cause a cyst. When we treated a patient with an impacted central incisor early, we could see a better prognosis. It means an early diagnosis and an exact treatment are very important. Generally if the impaction is not severe or it is caused by a keratinized covering tissue, a surgical exposure can induce an eruption easily but an orthodontic force is recommended when an eruption does not happen after a surgical method, when the eruption path is too transpositioned to be corrected spontaneously and when an impacted tooth is located so deeply. In the treatment using an orthodontic force, careful considerations about a root length, pulp, and a periodontal tissue can improve the periodontal and esthetic prognosis for the long follow-up results. This case is using an orthodontic traction following a periodic observation and in no expectation of spontaneous eruption. After treatment of this case, I have got some knowledges, so I report this case.

A 2.6GHz low noise amplifier (LNA) having 0.8dB of noise figure (NF), 13dB of gain and 10% of bandwidth is designed and measured using low noise HEMT (high election mobility transistor). The parasitic source inductance sue to the via-hole and its series feedback effects on performances and stability are considered. The measurement shows that fabricated LNA has 1.25dB of NF, 17.dB of gain, -6.46dB of input reflection coefficientm, and –19.65dB of output matching performances at 2,6GHz
