정용희,류미숙,김영식,이우인,이희주,서환조 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.1

Eikenella corrodens is a slowly growing, facultative anaerobic gram-negative bacillus. It is a normal inhabitant of the human upper respiratory tract, and it is recognized as an infrequent cause of invasive disease. To date, a few cases of E. corrodens infection were noted from all other organ. We report herein two cases of E. corrodens infection. In one case E. corrodens was isolated in the lung abscess and in the other case it was in the appendiceal abscess. The patients were treated empirically with penicillin G. The results of the bacterial culture and sensitivity test were available with it. The patients were discharged 15 days later with marked improvement after treatment. Our report clearly demonstrates that E. corrodens can be the pathogen of lung abscess and intraabdominal abscess. We reviewed descriptions from the literature of infections caused by E. corrodens.

Transarterial Chemoembilization (TACE) has been shown to be effective in patients with unresectable hepatocellular carcinoma (HCC) and can be applicable to patients with resectable HCC who reject operation. There have been studies concerning prognostic factors in patients with (HCC) undergoing TACE but they reported diffenrent prognostic factors from each other. The aim of this study is to estimate the survival rates and to determine which prognostic factors contribute to long-term survival after TACE of HCC. Thirty eight patients with HCC who had been treated by TACE were analized retrospectively. TACE was accomplished by hepatic arterial infusion of a suspension of lipiodol and anticancer drugs (Adriamycin), either alone or followed by gelfoam embolization. Male to female ratio was 4.4:l. Mean survival time was 463 days. Maximum survival time was 1,683 days. The overall cumulative survival rates at the end of the first and second years were, respectively, 54% and 38%. According to univariate analysis (log-rand scale test), variables significantly associated with survival were: tumor type, hepatic vein thrombosis, portal vein thrombosis, lipiodol uptake pattern, remained enhancement after TACE, AST, ALT, height and tumor size. Multivariate analysis (Cox proportional hazard model) for the significant variables in a univariate analysis revealed that the AST level, hepatic vein thrombosis, remained enhancement after TACE were statistically significant independent prognostic factors. The criteria of known contraindication may still be applied for TACE treatment of HCC. Additionally we should select the good prognostic patients without hepatic vein thrombosis and try to normalize the AST level if abnormal level before undergoing TACE. Thereafter, intensive chemoembilization to minimize the remained tumor is required to improve survival rates.

This study was conducted to investigate dietary patterns and assimilation of dietary culture of Korean descendants in Yanbian, China compared to Korean. A dietary survey was conducted using one 24-hour recall method from 730 adults over 30 years of age in Yanbian, China and 695 adults over 25 years of age in Kuri, Korea. The average number of food items consumed per day was 14 in Yanbian and 20 in Kuri and there was a significant difference between the two regions(p<0.001). The foods consumed most frequently were rice, salt, the M.S.G. in Yanbian and rice, green onion and garlic in Kuri. The foods consumed most by amount were rice, cucumber, Soju in Yanbian and rice, Kimchi and grape in Kuri. The average number of dishes consumed per day was 6.4 in Yanbian, 9.4 in Kuri and the difference between the two regions was significant(p<0.001). Total number of dishes appeared in the survey was 253 in Yanbian and 494 in Kuri. The dishes consumed most frequently were cooked-rice, beverages, Kimchi, stir-fried eggplant in Yanbian and cooked-rice, Kimchi, coffee, soybean paste stew, in Kuri. The dish groups appeared most frequently were rice, stir-fried foods, vegetables and Kimchi in Yanbian and rice, Kimchi, beverages and fruits in Kuri. Male subjects in Yanbian Consumed alcohol frequently while adults in Kuri consumed coffee more frequently than Yanbian. The major meal patterns were rice+side dish, rice+soup, rice+side dish+Kimchi in Yanbian and rice+soup+side dish+Kimchi, rice+side dish+Kimchi, rice+soup+Kimchi in Kuri. Stir-fried foods, which were consumed 46.6% of all the meals, were dominant side dish in Yanbian, but stir-fried food, seasoned vegetables and grilled food appeared aver 10% in Kuri. There results show that variety of diet of Korean-Chinese in Yanbian was lower than Kuri. Korean-Chinese tend to keep traditional Korean dietary patterns of consuming rice as staple but were adapted to Chinese dietary patterns of consuming stir-fried side dishes. Efforts should be directed toward preserving Korean traditional patterns of dietary culture among Korean-Chinese population.

CDMA 시스템에서는 이동국이 Open-loop 전력제어 및 Close-Loop 전력제어를 할 때 비 선형적인 AGC의 특성으로 인해 수신기의 감도가 현저히 낮아진다. 본 논문에서는 AGC의 비선형적인 특성 곡선값을 S/W로 선형화 시켜 RAS RAMDATA를 생성하고 이를 RAS RAM에 넣어 선형적으로 보상된 AGC특성을 얻는 알고리즘을 제안하였다. 그리고 실험을 통하여 그 유효성을 증명한다. In CDMA system, the sensitivity of receivers is lowered significantly due to characteristics of non-linear AGC when the mobile station implements open-loop power control and closed-loop power control. In this paper, We propose a algorithm that obtains linearly conpensated AGC characteristic by inserting the RAS RAM DATA in RAS RAM, which linearizes the value of non-linear characteristic graph in AGC by S/W, and the experimental results shows the validity.

Trichoderma koningii의 영양요구성 돌연변이주인 CUT 121로부터 얻은 원형질체를 야생형인 ATCC 26113의 핵과 혼합하여 PEG 용액을 처리한 결과, 독립영양형의 형질전화체가 30% 이상의 빈도로 생성되었다. 이 독립영양형 군체로부터 얻은 분리체 중의 하나는 xylanase의 활성이 야생형보다 3배 가량 증진되었으며, 다른 세포외 다당류 분해효소능도 야생형과 유사한 수준을 나타내었다. 분리체의 DNA 함량, 인위적인 분리양상 및 동위효소 양상 등을 조사 분석한 결과, 독립영양형의 형질전환체는 실험에 사용된 두 핵간의 유전물질교환에 의하여 생성된 형질전환체로 판명되었다. 이상의 결과로부터 Trichoderma속 균류의 균주개량법으로, 핵전이법이 통상의 원형질체 융합법보다 효율적인 것으로 판명되었다. When protoplasts from auxotrophic mutant of Trichoderma koningii CUT121(Lys^-, Met^-) were mixed with isolated nuclei of wild type T. koningii ATCC 26113 and treated with PEG solution, protrophic colonies were produced with frequency of more than 30 percent. One of segregants from prototrophic colonies showed increased xylanase activity and other polysaccharide-hydrolyzing activities comparable to those of wild type strain. Through measurement of DNA contents, induced segregation, and analysis of isozyme patterns, it was revealed that the prototrophic colonies were transformants resulted from exchange of genetic materials between the two kinds of nuclei used. These results suggest that nuclei transfer technique is more efficient than conventional protoplast fusion technique for strain improvement of Trichoderma species.

Tolclofosmethyl (TCFM) is heavily and annually applied to the turf soils of most golf courses in Gyeongju to control the fungi known to cause the disease brown patch. The soil samples used for the experiment was collected three weeks after the annual application at the end of May in the year 2002. The preliminary results obtained from this study demonstrated that the repeated field annual applications of TCFM to the turf soils of a golf course located in Gyeongju city in the southern area of Korea showed the enhanced degradation of the parent compound TCFM, especially in the surface (0~15 cm) soil rather than the shallow subsurface (15~30 cm) and deep subsurface (30~45 cm) soils, compared to the corresponding surface (0~15 cm) and shallow and deep subsurface (15~30 cm and 30~45 cm) soils of the untreated plot. It appears that microorganisms in the soil may be involved in the enhanced degradation of TCFM.
