腫瘍으로 인한 死亡率은 多樣한 名種 治療에도 不拘하고 循環器疾患 다음으로 2위를 차지하고 있다. 이에 著者는 韓醫學과 西醫學의 結合治療를 通해서 抗腫瘍藥物의 效果를 增進시키고 副作用을 줄이는 藥物의 開發을 爲하여 健脾 益氣 祛痰 補腎 杭癌效能을 갖고 잇는 扶正杭癌湯抽出液을 使用하여 Colony 形成抑制實驗, Sulforhoda-mine B(SRB) assay를 觀察하였고, 扶正抗癌湯抽出液과 抗癌化學療法劑인 Mitomycin C(MMC)를 Ehrlich carcinoma의 solid tumor와 ascites tumor에 各各 單獨 및 倂用 投與하여 抗腫瘍效果 및 Iysosomal enzymes의 活性에 대한 效果를 觀察하였다. 먼저 扶正抗癌湯抽出液을 Caki-1 cell, Hep 3B 및 A549에 투여한 후 增殖抑制作用을 colony 形成抑制實驗과 SRB assay를 통하여 觀察한 결과 濃度依存的으로 腫瘍細胞의 成長을 抑制하였다. Ascites form of Ehrlich carcinoma에 대한 抗腫瘍效果 實驗에서 扶正抗癌湯抽出液과 MMC를 병용투여한 결과, 扶正抗癌湯抽出液에 의하여 MMC의 抗腫瘍效果가 增加하였다. Solid form of Ehrlich carcinoma에 대한 抗腫瘍效果 實驗에서 扶正抗癌湯抽出液과 MMC를 병용 투여하였을 경우, MMC를 단독 투여하였을 경우보다 腫瘍의 크기가 현저하게 減少하는 결과를 보였다. Ehrlich ascites carcinoma cell에 扶正抗癌湯抽出液과 MMC를 병용 투여하였을 경우, MMC를 단독 투여하였을 경우보다 lysosomal enzymes의 活性이 强하게 나타났다. 本 實驗을 통하여 扶正抗癌湯抽出液은 MMC의 抗腫瘍效果를 증가시키는 效果를 보였다. 또한 扶正抗癌湯抽出液은 마우스에서 solid form of Ehrlich ascites carcinoma의 크기를 감소시키는 效果를 나타냈으며, 생존기간 實驗에서는 扶正抗癌湯抽出液과 MMC를 병용투여시 ascites tumor에 MMC를 단독으로 투여하였을 때와 비교하여 유의하게 생존기간을 증가시키는 결과를 보였다. 이상의 결과를 종합하여 볼 때 扶正抗癌湯抽出液은 用量에 依存的으로 直接的인 抗腫瘍效果가 있으며, 抗癌療法劑인 MMC의 效果를 亢進시키는 것으로 보아 間接的인 抗腫瘍效果도 있을 것으로 思科되나 正確한 效果를 究明하기 위해서는 보다 正確한 抗腫瘍機轉에 대한 硏究와 藥物學的 硏究 및 臨床的 硏究가 追加되어야 할 것이다. In order to investigate the effects of Bujeonghangamtang Extract(扶正抗癌湯抽出液) on antitumor effects after human cell lines(A549, Hep3B, Caki-1, Ehrlich) transplantation into the peritoneal cavity or right groin in mice induced by RPMI 1640 and DMEM etc, the extracts of its herbal medicines were orally administered for 10 or 12 days. Experimental studies were performed for measurement of antitumor effect of Mitomycin C(MMC) and lysosomal enzyme's activities using colony forming efficiency, SRB assay which were regarded as a valuable method for the measurement of antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows: 1. The change of colony-forming efficiency and SRB assay of Caki-1 cells, Hep3B and A549 Cells after exposure to the extract of Bujeonghangamtang extract depressed the growth of tumor cells by concentration of Bujeonghangamtang. 2. Antitumor activity of the ethanol extract of Bujeonghangamtang extract and MMC on ascites form of Ehrlich carcinoma in mice is slightly improved. Especially the mean of survival times in the group of 200㎎/㎏ and MMC 0.1㎎/㎏ is improved over 30.9%. 3. When Bujeonghangamtang extract and MMC are administered together, the weight of tumor is more decreased than MMC alone. 4. The lysosomal enzyme's activities of the Bujeonghangamtang extract and MMC are more significantly improved than MMC alone. According to the above result, it could be suggested that Bujeonghangamtang extract has indirect antitumor effect by the increase of MMC uptake.

The Ameliorative Effects of Korean Bean‐Leaves on Inflammation and Liver Injury in Obese Rat Model

Byung?Moon Jin,Seok?Cheol Choi,Hye?Sook Lee,Sang?Bong Jung,Kyung?Yae Hyun 대한의생명과학회 2013 Biomedical Science Letters Vol.19 No.3

Obesity may cause metabolic syndrome and adult diseases. This study was undertaken to investigate the ameliorative or useful effects of beanleaves on inflammation and liver damage in obese rat models. Rats were divided into three groups: a control group (normal diet, n=6), a fat diet group (45%?fat diet, n=7), and a bean leaf group (45%?fat+Korean bean leaves diet, n=7). Body weights in the bean leaf group were lower than those of the fat group (P<0.05). Serum tumor necrosis factor?α (TNF?α) and prostaglandin E₂ (PGE₂) concentrations were lower in both the control and bean leaf groups than in the fat group (P<0.001). TNF?α concentrations in the bean leaf group were slightly higher than in the control group but statistically significant (P<0.05). The bean leaf group histologically exhibited lower fatty degeneration, spotty necrosis, and leukocyte infiltrations in hepatic tissues than those of the fat group. In the homogenized liver tissues, the cyclooxygenase?2 (COX?2) gene was only expressed in the fat group. The gene expression levels of hepatic TNF?α, inducible nitric?oxide synthase, peroxiome proliferator?activated receptor?α (PPAR?α), poly (ADP?ribose) polymerase (PARP), and transforming growth factor?β1 (TGF?β1) were weaker in the bean leaf group than in the fat group. These results suggest that adding bean?leaves to the diet may ameliorate obesity?induced systemic inflammation and liver damage and that bean leaves may be a useful food for preventing obesity and thereby metabolic syndrome and adult diseases

THERRESTRIAL IMPACT CRATERING CHRONOLOGY: A PRELIMINARY ANALYSIS

Moon, Hong-Kyu,Mi, Byung-Hee,Fletcher, Andre-B.,Kim, Bong-Gyu The Korean Space Science Society 2001 Journal of Astronomy and Space Sciences Vol.18 No.3

We have recently compiled a database of the properties of 192 impact craters, which supercedes previous compilations. Using our database, the impact structures found in North America, Europe and Australia have been examined; these cratonic areas have been relatively stable for considerably long geological periods, and thus have been best preserved. It is confirmed that there is a close correlation between the geological epoch boundaries, the epochs of mass extinctions, antral the "timing" of impacts. In addition, the terrestrial cumulative flux of objects >20km is found to be $1.77{\times}10^{-15}km^{-2}yr^{-1}$, over the last 120 Myr, which is much smaller than the published values in McEwen et al. (1997) and Shoemaker (1998) ($5.6{\pm}2.8{\times}10^{-15}km^{-2}yr^{-1}$. For terrestrial impact structures with D> 50 km, the apparent cumulative flux over the last 2450 Myr is ~50 times smaller than the corresponding value for the Moon. If we assume that the Earth and the Moon suffered the same level of bombardment over this time, this would mean that the actual flux of impacting bodies, capable of making craters with D)50 km, was ~ 50 times larger than the apparent flux estimated from the currently known terrestrial records.

Moon, Sung-Hwan,Kim, Seong-Oh,Yu, Hyung-Seong,Choi, Byung-Jai,Choi, Hyung-Jun,Lee, Jae-Ho 大韓小兒齒科學會 2006 大韓小兒齒科學會誌 Vol.33 No.2

이번 연구의 목적은 혼합치열기 아동에서 미맹출된 견치와 소구치의 크기를 예측하는데 있어서 한국인에 맞는 방정식을 만들기 위함이다. 미맹출 치아의 크기를 예측하는 것은 혼합치열기 교정 진단과 치료계획 수립에 있어서 매우 중요하다. 미맹출된 견치와 소구치 크기를 예측하는 방법은 몇가지가 있지만 그중에서도 가장 흔하게 쓰이는 것이 모이어의 예측표와 다나카와 존스턴의 방정식이 있다. 하지만 그것들은 백인을 위해서 제작된 것이고 치아 크기는 인종에 따라서 다르다고 알려져 있다. 이번 연구에서는 치아크기를 측정하여 하악 영구 절치의 크기 합과 견치 및 소구치의 크기 합 사이의 상관관계를 구하고 회귀방정식을 이용해서 한국인에 맞는 예측표를 만들었다. 연세대학교 치과대학에 재학중인 178명의 한국 학생(남 108명, 여 70명, 평균연령 21.63)을 대상으로 실험하였다. 영구치의 근원심 폭경을 석고모형상에서 calipers를 이용해서 측정하였다. 성별간의 치아 크기는 차이가 있었다(p<0.05). Correlation coefficient는 0.57에서 0.64의 범위였고, standard errors of the estimates 는 여성에서 0.6으로써 남성보다 우수하였다. r^(2)값은 0.27에서 0.41의 범위를 나타내었다. Estimating the size of unerupted teeth is an essential aspect of orthodontic diagnosis and treatment planning in the mixed dentition. Several methods were introduced and used for the prediction. The most common methods among these would be Moyers probability chart and Tanaka and Johnston equations. These are currently used widely, but they were developed for Caucasians. Because there are clear racial differences in teeth size, the objectives of this study were to produce correlation coefficients between the combined mesiodistal widths of the permanent mandibular incisors and those of the canines and premolars for each quadrant, and prediction tables with regression equations, specifically for Korean. 178 young adults (70 women, 108 men, mean age 21.63 years) were selected from the College of Dentistry, Yonsei University, Seoul, Korea. The mesiodistal crown diameters of the permanent teeth were measured with calipers. Significant sexual dimorphism was found in tooth sizes. The correlation coefficients between the total mesiodistal width of the mandibular permanent incisors and those of the maxillary and mandibular canines and premolars were found to be between 0.52 and 0.64. The standard error of the estimatation was better (0.60) for women and the r^(2) values ranged from 0.27 to 0.41 for both sexes, Prediction tables were prepared for Korean. This study showed larger canine and premolar diameters than Tanaka and Johnston's and Moyers' studies which might be due to the racial differences. Further investigations with a larger sample size will be needed for more representative data on the Korean population.

문병현,이재홍 大邱大學校 科學技術硏究所 1995 科學技術硏究 Vol.2 No.2

직접 스펙트럼 확산 통신 시스템에서는 의사 잡음 시퀀스(PN Sequence)가 일반적으로 사용된다. 그러나 의사 잡음 시퀀스 혹은 m 시퀀스의 갯수는 한정되어 있다. 또한 주기가 2ⁿ-1로서 항상 홀수로 주어지므로 시스템 동기에 부적합한 경우가 있다. 이를 해결하기 위해 확장 m 시퀀스(Extended m sequence)는 의사 잡음 시퀀스의 길이를 하나 더 증가시켜 2ⁿ으로 만들어진다. 임의의 길이를 가지는 무한히 많은 시퀀스를 생성할 수 있는 캐이오틱(Chaotic) 시퀀스 또한 스펙트럼 확산 통신 시스템에서 사용 가능성을 제시하였다. 본 논문에서는 일반적으로 사용되는 의사 잡음 시퀀스를 확산 m-시퀀스, 가자미(Kasami) 시퀀스, 골드(Gold) 시퀀스 및 캐이오틱 시퀀스의 상관 특성과 비교 분석하였다.

가우스 잡음과 CO-CHANNEL 간섭이 존재하는 채널에서의 최대추정 프레임 동기

문병현 대구대학교 (한사대학) 산업기술연구소 1993 産業技術硏究 Vol.12 No.-

The problem of locating a periodically inserted frame synchronization pattern in random data for a binary pulse amplitude modulated (PAM) digital communication system over an additive white Gaussian noise (AWGN) channel with co-channel interference is considered. The performance degradation of frame synchronization for the correlation rule due to the presence of co-channel interference is shown. The maximum likelihood (ML) decision rule for the frame synchronization over an AWGN channel with co-channel interference is derived. The ML frame synchronization rule obtains about 1dB signal energy gain over the correlation rule. Specially, the ML rule obtains as much as 2 dB gain over the correlation rule when the SNR is greater than 0 dB.
