The rsmA gene was cloned from soft-rot bacterium Pectobacterium carotovorum subsp. carotovorum LY34 (Pcc LY34), and its role in pathogenicity was investigated by marker exchange mutagenesis. From a cosmid library of Pcc LY34 genomic DNA, a positive clone carrying the rsmA gene was selected, and the gene was cloned by polymerase chain reaction (PCR) amplification. The gene is 186 bp in size and encodes a protein of 62 amino acids with a predicted molecular mass of 6,839 Da. The calculated pI of the RsmA is 8.16. The phylogenetic tree showed that the RsmA of Pcc LY34 appeared genetically identical to the CsrA of Pectobacterium atrosepticum SCRI1043 (100% identity) and similar to the CsrA of Yersinia pestis KIM10+(98.3%). The gene was disrupted by the $Km^r$ gene, and the cells became mutated (i.e., $RsmA^-$ mutant). The pathogenicity test revealed that the disease rating of the $RsmA^-$ mutant only differed slightly from that of the wild type on a slice of potato tuber and a Chinese cabbage stalk. These results suggest that RsmA is not an essential factor for the pathogenicity of Pcc LY34 and that the rsmA gene of Pcc LY34 is not completely derepressed in the $RsmA^-$ mutant for virulence-related genes, contrary to the results of Erwinia carotovora subsp. carotovora $RsmA^-$ mutant, which proved hypervirulent for celery petioles. These results showed that the microenvironmental conditions of the host and/or strain of pathogen are important for the coordination of virulence gene expression.

연구목적: 팀티칭에 근거한 통합강의는 최근 대부분의 의과대학에서 시행되는 강의형태이다. 그러나 기 존에 사용되고 있는 온라인 강의평가 방식은 이러한 강의 특성에서 나타나는 문제점을 파악하기 힘든 점이 있다. 본 대학에서는 팀티칭에 의한 통합강의에서 문제강의를 직접적으로 파악하는 ‘문제강의 직 접평가지’를 개발하였다. 본 연구의 목적은 새로이 개발된 문제강의 직접평가지가 강의개선에 끼친 영 향력을 알아보고자 하는 것이었다. 연구방법: 2007년 2학기부터 2009년 2학기까지 충북대학교 의과대학 1, 2학년을 대상으로 문제강의 직접평가지에 의한 강의평가를 실시하였다. 평가지 질문 중에서 두 가지 객관식 질문에 대한 답변을 분 석대상으로 선택하였다. 질문은 첫째, ‘가장 유익하고 도움이 많이 되었던 강의들은 무엇입니까?’와 둘 째, ‘가장 어렵거나 이해하기 힘들었던 강의들은 무엇입니까?’였다. 강의평가를 실시한 강좌들 중에서 2 년 이상 연속적으로 강좌구조와 평가지의 객관식 질문 형식이 변하지 않은 14개의 강좌를 분석대상으로 하였다. 각각 연도의 평균 긍정비율을 다른 연도의 것과 카이제곱 검정 방법을 사용하여 비교하였다. 결과: 14개의 강좌 중에서 시작연도와 마침 연도 간에 긍정비율이 증가된 경우는 13개 강좌였다. 그 러나 통계적으로 의미가 있는 경우는 5개 강좌에서 나타났다. 결론: 문제강의 직접평가지에 의한 문제강의를 판별해 내는 방법은 단기간에 통합강좌의 개선에 효과 적이다.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

In this study, we investigated the anti-oxidative effects, antimicrobial, and anti-inflammatory activities of the extracts from broccoli to evaluate its use as a functional ingredient in cosmetics. The extracts are WE (water extract at RT), MWE (mineral water extract at RT), EE (70% ethanol extract at RT), and USEE (heat process for 12 hours at 60℃ after ultrasonification for six hours with 70% ethanol). The measurements of the total polyphenol content from broccoli extracts were highest in EE at 425.24±13.9 mg/g dry. The result of electron donating ability of EE was the highest at 10,000 ㎍/㎖ as 97.81% and increased in a concentration-dependent manner. The ferric reducing antioxidant powder (FRAP) of EE was the highest at 10,000 ㎍/㎖ as 1235.6 μM. In an antimicrobial activity test, the EE showed significant antimicrobial activity against S. epidermidis, S. aureus, E. coli, P. acnes, and P. ovale. Furthermore, broccoli extract exhibited no cytotoxicity in RAW 264.7 cells. Also anti- inflammatory activity by NO assay showed LPS-induced NO was significantly inhibited following treatment with EE of 1,000 ㎍/㎖. Therefore, the broccoli ethanol extract can be used as a resource of natural cosmetic material for functional cosmetics.

Competitive ELISA methods were used to measure the level of aflatoxin M1 (AFM1) from urine in 1008 Korean adults. Subjects were selected by random sampling in all areas of Korea, except Cheju-do. The recovery rate of AFM1 using this method was 105% (73-124%). The geometric mean of urinary AFM1 in all subjects was 3.43 pg/mL (3.67 ng/g creatinine). The level of AFM1 in males was statistically higher, compared with female subjects. However, the levels of AFM1 did not differ according to age. Subjects in Chungbuk-do showed the highest urinary AFM1 concentration, whereas subjects in Kyeongnam-do showed the lowest concentration. Assuming an excretion rate of 5%, this AFM1 excretion corresponds to approximately 0.1 microgram/day in Korean adults.

Objectives : The purposes of this study are to evaluate the effect of treatment in obesity clinic in Dae-Gu Hanny University and to improve the oriental medical methods of treatment in obesity patients. Methods : 62 patients were classified into four groups by Body Mass Index(BMI) : normal, overweight, 1st obesity and 2nd obesity groups. Weight, BMI, body fat rate and abdominal fat rate were compared in each group by t-test. Results : In distribution of sex, male were 10(16.1%), female were 52(83.9%). Mean age was $31.0{\pm}2.59$ and the patients in twenties and thirties were the most. Mean weight was $71.80{\pm}4.08kg$ and 1st obesity group(23) was the most. Mean BMI was $27.11{\pm}1.20(kg/m^2)$. BMI Changes in obesity groups treated by obesity clinic were $0.95{\pm}0.68kg/m^2$ in normal group, $1.45{\pm}0.38kg/m^2$ in overweight group, $2.67{\pm}0.48kg/m^2$ in 1st obesity group and $4.01{\pm}1.10kg/m^2$ in 2nd obesity group. The changes in all groups were significant. The more the obesity degree was. the more weight loss was. Conclusions : The weight and BMI in patients were almost decreased significantly when they treated. It resulted that the effect of oriental medical treatment in obesity was positive. This study is the effect of treatment in obesity by several medical methods and it is thought that the study of the effects of treatment in obesity by each medical methods that were used in this study is necessary.

This study was designed to evaluate the effects of the oriental medicine(Sojeockjeongwonsan) on a Jeock-Jeung patient. The clinical data was analyzed on a patient with Jeock-Jeung, deemed due to Gangiulgyul(肝氣鬱結) and Junggiheoyak(正氣虛弱). The patient’s main symptoms were abdominal pain and abdominal mass. The patient was admitted to Dae-Gu Hanny University Dae-Gu Oriental Medicine Hospital. Clinical symptoms, including abdominal pain, abdominal mass and general condition, improved after treatment. This study suggests that Sojeockjeongwonsan is significantly effective in treatment of a Jeock-Jeung.

Septoplasty with turbinate surgery is common surgical treatment In patients with septal deviation and chronic hypertrophic rhinitis. The aim of this study was to evaluation objective outcomes of septoplasty with turbinate surgery by analysis of subjective symptom score with objective acoustic rhinometric test before and after surgery, prospectively. Materials and Methods: We reviewed 45 adult patients which were done septoplasty with bilateral turbinectomy or turbinoplasty and followed up at least 3 months by one rhinologist from November 1999 to April 2000, prospectively. We analyzed subjective symptom score. minimal cross-sectional area (MCA) , C-notch cross-sectional area, and total volume of both nasal cavity before and after surgery. Correlation test was studied between symptom improvement and acoustic rhinometric results. Results: Twenty nine cases were male and sixteen cases female. The average age was 26.9 year-old (range: 17 to 57 years). There was significantly improvement of symptom score in postoperative 3 months (p<0.05). There was significantly increased C-notch cross-sectional area and total volume in postoperative 3 months. Symptoms improvement were associated with acoustic rhinometric profiles, but, there was not significantly correlation. Conclusion: Septoplasty with turbinate surgery is considered to be effective for nasal obstruction in patients with septal deviation and turbinate hypertrophy. Acoustic rhinometric test is favorable objective test for evaluation of symptom improvement after septal surgery.
