목적 : 국내에서 발열을 동반한 호중구감소증이 있는 악성 종양환자에게 경험적 항생제로 베타락탐계 항생제와 아미노배당체의 병합요법의 사용이 일반적이다. Cefepime은 광범위 항균 작용을 가지고 있어, 그람 음성균 뿐만 아니라 그람 양성균에 대해서도 우수한 효과를 나타낸다. 재료 및 방법: 발열을 동반한 호중구감소증이 있는 악성 종양환자를 대상으로 무작위, 공개, 비교 연구를 시행하였다. 대상 환자를 무작위로 cefepime 단독요법군과 ceftazidime 및 tobramycin 병합요법군으로 나누어 투여하고 각각의 임상적 효능과 안전성을 비교하였다. 구강및 인후 점막염이 있는 환자에서 분리된 녹색 연쇄알 구균에 대한 항생제 내성 정도를 조사하였다. 결과 : 대상환자 89명 중 CA 투여군이 48예(53.9%), CT 투여군이 41예(46.1%)이었다. 발열의 유형별로 MDI는 18예(20.2%), CDI는 9예(10.1%), UF는 62예(69.7%)로 두 군 간에 차이가 없었다. CA 투여군과 CT 투여군의 임상적 호전률은 시험약 투여 후 2-4일째 각각 91.7%, 85.4% (P=0.31), 치료 종료 시 각각 91.7%, 100% (P=0.15)로 두 군간에 유의한 차이가 없었다. 치료 종료 시 CA 투여군과 CT 투여군의 세균학적 소실률은 모두 100%로 두 군간의 유의한 차이가 없었다(P=0.78). 점막염이 있는 환자로부터 녹색 연쇄알 구균이 분리된 경우는 25예(28.1%)이었으며, 분리된 녹색 연쇄알 구균은 penicillin, ceftriaxone, cefepime, vancomycin에 모두 감수성을 보였다. 약제 관련 이상 반응의 발생 빈도도 두 군간에 유의한 차이가 없었다. 결론 : 발열을 동반한 호중구감소증이 있는 악성 종양환자의 경험적 항생제로서 cefepime 단독요법은 ceftazidime 및 아미노배당체의 병합요법만큼 효과적이고 안전하였다. Background : Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. Materials and Methods : To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. Results : A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC_(90) 0.12 ㎍/mL), cefepime (1 ㎍/mL), and vancomycin (0.12 ㎍/mL). Conclusion : Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.

많은 연구에서, 유치와 그 계승 영구치의 선천적 결손 간에는 상당한 연관관계가 있는 것을 보고하였다. 그러나 하악 전치부에서, 유치의 선천적 결손에도 불구하고, 그 계승 영구치는 정상적으로 존재하는 증례가 임상적으로 종종 관찰되기도 한다. 본 연구의 목적은 한국 어린이에서 하악 유절치와 그 계승 영구치의 선천적 결손 간의 상호 연관관계를 평가하는 데에 있다. 2005년 1월 1일부터 2008년 9월 5일까지 서울대학교치과병원에 내원하여 파노라마 방사선사진을 촬영한 6세 이하의 남녀 어린이 총 14,307명을 대상으로 하악 전치부의 치아양상을 관찰하여 유치와 영구치의 선천적 결손 관계를 평가하여 다음과 같은 결과를 얻었다. 1. 하악 유절치의 결손률은 0.24%였으며, 하악 유절치가 존재 시 후속 영구치가 존재할 승산(odds)은 7163.5였으며, 유절치의 결손 시 후속 영구절치가 존재할 승산(odds) 0.79였다. 2. 하악 유절치 결손의 증례 중 후속 영구치가 모두 존재하는 경우는 44.12%였다. 유절치의 양측 결손 시 후속 영구치가 하나라도 존재할 승산(odds)은 유절치 편측 결손 시에 비하여 1.57 배였다. 3. 유절치 결손이 있을 때 유절치의 편측 결손일 승산(odds)은 여자가 남자에 비해 2.2 배였다. 또한, 유절치 결손이 있을 때 후속 영구절치가 존재할 승산(odds)은 남자가 여자의 경우에 비하여 2.22 배였다. Many studies have shown that there is a strong relationship between the congenitally missing primary teeth and their succedaneous permanent teeth. However, especially in case of lower anterior region, we can observe the existence of permanent teeth even though their precedent primary teeth were missed at times. The purpose of this study was to reveal the relationship between the congenitally missing primary lower anterior teeth and their succedaneous permanent teeth in Korean children. Total of 14,307 children, under 6 years of age, who attended the department of pediatric dentistry, Seoul National University Dental Hospital, Seoul, Korea from January 1st 2005 to September 5th 2008 were radiologically examined using the panoramic x-ray in order to analyze the relationship between the congenitally missing primary lower anterior teeth and their succedaneous permanent teeth. The results were as follows : 1. The prevalence of congenitally missing lower anterior teeth in primary dentition was 0.24%. The odds ratio of both the primary and permanent anterior teeth being present was 7163.5 and only the permanent anterior teeth being present was 0.79. 2. The percentage of all succedaneous permanent teeth being present was 44.12% in cases of missing lower primary anteriors. The odds ratio of at least one succedaneous permanent teeth being present in cases of bilateral primary anterior teeth missing was 1.57 times more common than in cases of unilateral primary teeth missing. 3. The odds ratio of primary missing teeth being unilateral was 2.2 times higher in females. Moreover, the odds ratio of succedaneous permanent teeth being present in cases of primary teeth missing was 2.22 times higher in males.

Tracheobronchopathia osteochondroplastica (TPO) is a rare benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. Although some disorders were reported combined with TPO, these seemed to be considered casual. We report a case of TPO that combined with adenocarcinoma of lung. She was 50-year-old non smoking woman presented with chronic cough with right chest pain. Lung mass on right lower lobe was found on chest x-ray, so lung cancer was suspected. Multiple scattered whitish small elevations from trachea to bronchial trees were found on bronchoscopic exam. We mistook these lesions for metastases from lung cancer and biopsies of these lesions were done. Transbronchial biopsy for right lower lobe mass lesion was also done. But biopsies from trachea and bronchus revealed TPO rather than lung cancer. Transbronchial lung biopsy of right lower lobe mass was diagnosed adenocarcinoma of lung. So TPO combined with adenocarcinoma of lung was diagnosed.

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.

고능력 젖소 축군의 집단번식관리프로그램 적용에 의한 번식효율의 개선

노경수,김의형,남현욱,서국현,강현구,김일화 충남대학교 형질전환복제돼지연구센터 2004 논문집 Vol. No.8

We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group). Intervals from calving to first service (99.6 vs. 81.8 days) and to conception (160.3 vs. 131.8 days) were shorter in the RHHP group than in the pre-RHHP group. Secondly, we determined the effect of milk yield (305 days) on the occurrence of postpartum diseases, BCS changes, and reproductive performance in cows under RHHP, The occurrence of metritis and metabolic diseases were greater in the over-10,000 kg group than in the under-l0,000 kg group. The over-10,000 kg group lost more body condition than the under-10,000 kg group from calving to month 3 postpartum. Nevertheless, reproductive performance did not differ between the two groups. These results indicate that reproductive performance can be improved by the application of RHHP in high yielding dairy herds and that reproductive performance in the cows under RHHP are not affected by high milk yielding.

英語敎師 現職敎育에 關한 硏究

崔錄郁 釜山大學校 師範大學 1977 교사교육연구 Vol.4 No.1

The purpose of this study is to do two things: first, to elucidate the significance of in-service training for teachers of English; second, to find an answer to the programme of in-service training that senior teachers of English propose to meet their needs in their profession. The former was done through the study of the literature dealing with in-service education, particulary for teachers of English, and the latter through a questionnaire to be answered by the teachers of English in mid-career. At the present time, it is to some extent true that in Korea the main stage of English teaching is the secondary sohool, whose teachers of English must be the basis for English education. In addition, educational social change has brought a new attitude to teaching and learning of English, and technological change electro-mechanical equipment and its associated techniques into the classroom. To be brief, teachers of English must remain abreast with recent developments in English education. As for the specific programme for the in-service training, its contents above all things must be connected with the new mechanical aids and the things that teachers of English need in their profession and in which they are unlikely to have had any training during their initial training. In order to do this, it is a sine qua non that we should make use of the opinions and ideas about the in-service training that its participants suggest. The reason is that most of them have not only a lot of teaching experience but also sound knowledge of fundamental academic disciplines of linguistics, psychology, English teaching, and so on; moreover, they can usually judge what is and what is not relevant to them in their profession. Summing up, the materials gained from them have come to the following result. The courses they took in the past in-service training were under a bias toward theoretical speculative ones. Therefore, the courses they want to take are practical, descriptive, and theoretical ones in that order. From what has been mentioned above, the courses of in-service training for teachers of English can be seen to have three interrelated aspects: the practical aspect, the descriptive aspect, and the theoretical aspect. What I wish to suggest finally here is that any in-service training cannot be effective without the participants' strong willingness to learn, a desire to promote their professional growth.

In Korea, 500,000M/T of fish soluble and 9,910,000M/T of briquette-ash are yearly produced and discarded as waste materials. A series of experiments was performed to develop fish soluble-absorbed briquette ash feed(FBF) in order to utilize the protein, UGF, Ca contained in the abandoned fish soluble and Fe, Zn, and other microminerals in the discarded briquette-ash. From the year 1981 to 1984 the chemical composition of briquette-ash was analyzed and its feeding effects on sucking, growing and fattening pigs were studied. Also the effects of briquette-ash addition for substituting Fe injection in pigs at sucking were examined. After the potential of briquette-ash feed was proved, from the year 1985 to 1989 fish soluble-absorbed briquette ash feed(FBF) was made and previously fed from 5 to 10%, subsequently, 3, 5, and 10% of pig ration was substituted by FBF and its effects on sucking pig as substitution for Fe injection, its feeding effects on growing, fattening and growing-fattening pigs, changes during storage, digestibility, economics, backfat thickness and hematological values were examined and gave results as follows. 1. Analysis of proximate composition and mineral contents of briquette and briquette-ash. Briquette-ash contained moisture(0.15%), C·protein (0.52%), C·fat (0%), C·fiber (4.13%), NFE (0%), C·ash (95.35%), Ca (0.807%), P (0.074%), K (0.138%), Na (0.025%), Mg (0.025%), Mg (0.183%), Fe (3,769mg/kg), Mn (98mg/kg), Zn (139mg/kg), Cu (21.0mg/kg). And in the briquette contained NFE (10.96%), C·ash (71.35%), Ca (0.224%), P (0.043%), K (0.158%), Na (0.039%), Mg (0.19%), Fe (7,385mg/kg), Mn (116mg/kg), Zn (306mg/kg), Cu (17.5mg/kg). 2. Analysis of Fish soluble-absorbed Briquette ash Feed (FBF). To study the effects of feeding Fish soluble-absorbed Briquette ash Feed (FBF) in pigs, firstly the chemical composition, mineral contents and amino acids contents of briquette ash absorbed concentrated fish solubles were analyzed. Increasing absorbed rate of concentrated fish soluble to briquette ash, chemical composition, mineral contents and amino acids contents resulted higher. 3. When the briquette-ash was fed ad libitum to sucking and growing-fattening pigs as micromineral supplements; (1) Body weight gain was little higher in the briquette-ash supplied group than control(p>0.05). (2) In the growing-fattening pig, feed efficiency was better in the control group (4.71) than the briquette-ash supplied group (4.84). (3) In the weaning pig the feed efficiency was 3.0 and suplemental effects of briquette-ash were outstanding in atrophic pigs. (4) Making economical analysis by term of feed cost per kg weight gain, in the briquette-ash supplemented group, the feed cost was increased to 852 won where it was 829 won in the control group. (5) In the weaning pig group, 528 won was used per kg weight gain. (6) The palatability of briquette-ash was good and healty conditions were normal, too. 4. When the briquette-ash was supplemented in 3%(T1), 5%(T2) and 10%(T3) to the sucking, weaning and growing pigs; (1) When the briquette-ash was fed as substitution for Fe injection for sucking pigs, the growing state and health conditions were good enough. (2) Body weight gain was best when 3% of briquette-ash was supplemented(p>0.05). (3) There was no significant difference in feed efficiency(p>0.05). (4) Feed costs required per kg weight gain for T1, T2 and T3 were 636.40, 672.52 and 684.56 won respectively. (5) Hematological values of treatment group were in normal range. 5. Effects of briquette-ash addition as substitution for Fe injection when breeding and sucking pigs are fed with briquette-ash. (1) The pig of this college (5.27kg) had slightly heavier average weight at the age fo 3 wks. than the purebred of National Livestock Breeding Station(5.00kg). (2) The purebred (8.3pigs. 88.3%) had higher litter size and survival rate at weaning than the pig of this college. (3) The pig of this college (17.8kg) had slightly heavier average weight at weaning than the purebred of National Livestock Breeding Station (17.4kg). (4) In the group equal to farrowing season and litter size at sucking, there were nonsignificant defferences for the reproductive traits between briquette-ash addition and Fe injection group. (5) When fed liberally, briquette-ash as the substitute for Fe injection in sucking pig, there is relatively superior tendency to the growth and health conditions in pigs. 6. When the Fe injection was reduced to once and briquette-ash was supplied liberally; (1) Pig weight at 21 days was heavier in the pigs feeding briquette-ash after injected Fe once than in those injected Fe twice. (2) Pig weight at weaning(16.8kg) was lower in the pigs feeding briquette-ash after injected Fe once than in those injected Fe twice (17.4kg). (3) Pig weight at 15 wks. was heavier in the pigs feeding briquette-ash after injecte Fe once (48.85kg) than in those injected Fe twice (46.0kg). (4) Final body weight was heavier in the pigs feeding briquette-ash after injected Fe once (78.3kg) than in those injected Fe twice (71.6kg). (5) Feed efficiency was better in the pigs feeding briquette-ash after injected Fe once (2.32) than in those injected Fe twice (2.34) (6) The health conditions of the pigs feeding briquette-ash injected Fe once were normal. (7) The results obtainced in this study suggest that briquette-ash feeding can substitute Fe injection effectively supplementing sufficient microminerals from growing to fattening. 7. The results of feeding briquette-ash to pigs during 4 years from 1981 to 1984 in substitution for Fe injection and as micromineral supplements are reviewed. Generally, when sows are fed briquette-ash ad libitum, there were no significant differences in birth weight, weight at 21 days and weight at 56 days. The survival rate was better in the briquette-ash supplemented group. However when the briquette-ash was supplied continuously after weaning, there were significant differences in weight at 15 days, weight gain and feed efficiency. In conclusion, it might be suggested that the pigs farrowed from sows fed ad libitum briquette-ash could grow without Fe injection and when fed briquette-ash ad libitum, it can prevent micromineral deficiency and gain body weight more rapidly. 8. When FBF was added by 5% in the growing pig ration and 10% in the fattening pig ration; (1) Daily body weight gain was higher in the treatment group (784.52g) than the control group (645.24g). (2) Feed intake was higher in the treatment group (185.53kg) than the control group (165.46kg). (3) Feed efficiency was significantly higher in the treatment group (2.82) than the control group (3.05). (4) Adding FBF in ration, 49.45 won was saved per kg body weight gain. (5) Ages at 90kg were shortened by 14 days in the treatment group (155d) than the control group (169d). 9. Effects of levels 0%(C), 3%(T1), 5%(T2), and 10%(T3) of substitution of FBF (1) Growing period 1) Daily body weight gain was higher in the treatment group (T1:658g, T2:686g, T3:683g) than the control group (618g). 2) Daily feed intake was in order of T3:1.61kg>T2:1.59kg>T1:1.55kg>C:1.54kg. it increased according to the level of fish soluble. 3) Body weight gain was in order of T2:38.47kg>T3:38.20kg>T1:36.83kg>C:34.59kg. Feed efficiency was in order of T2:2.32>T3:2.37>T1:2.36>C:2.49. Generally the treatment group was better than the control group. 4) Feed cost per kg weight gain was lowest in T2(291.24won) and it saved 24.62won per kg weight gain compared to the control group. 5) There was no significant difference in the digestibility of growing diets and it was stable during the storage period. (2) Fattening period 1) Daily weight gain was higher in T3 (779.33g) and T2 (752.0g) than control (674.0g) significantly (p<0.01). Feed efficiency and ages at 90kg were also better in the treatment group. 2) Digestibility was improved in the treatment group by not signivicantly. 3) Until the 7th day of storaging period, the chemical composition of FBF added ration decreased but it did not show any change until the 27th day. 4) Backfat thickness was significantly (p>0.01) thinner in T3 (1.51cm) than control (1.56cm). 5) Dressing percentage was significantly (p>0.01) higher in the treatment group (63.67∼64.65%) than in the control group (61.99%). 6) Feed costs required per 1kg weight gain were 386.81 won in control, 374.91won in T1, 347.79 in T2 and 336.99won in T3. As result feed costs were saved adding FBF in the ration. (3) Growing-fattening period 1) Weight gain, feed efficiency and ages at 9kg were significantly higher in FBF added T2(5%) and T3(10%) group. 2) Digestibility of growing and fattening diet was improved in the treatment group but not significantly. 3) The chemical composition of FBF added ration decreassed slightly till the day 7 of storaging period. But after 7th day it did not show and change untill the dat 27. 4) Backfat thickness was significantly (p<0.01) thinner in T3 (1.51cm) than control (1.56cm). 5) Dressing percentage was significantly (p<0.01) higher in the treatment group (63.67∼64.65%) than in the control group (61.99%). 6) Feed costs required per 1kg weight gain were 350.71won in control, 336.32 won in T1, 320.89won in T2 and 316.11won in T3. As result feed costs were saved when FBF was added in the ration. 10. When the ration was substituted by FBF and fish soluble by 10% respectively; (1) Final weight and daily weight gain were 94.05kg, 678g in control group whereas 98.65kg, 752g in FBF substituted ration and 95.40kg, 709g in fish soluble substituted ration. (2) Feed efficiency was 3.65 in control group whereas 3.24 in FBF substituted ration and 3.40 in fish soluble substituted ration giving better resuluts. (3) Feed cost required per kg weight gain was in order of FBF substituted ration (369.33 won), fish soluble substituted ration(388.15 won) and control group (413.56 won). (4) Ages at 90kg were in order of FBF substituted ration (162.1), fish soluble substituted ration (163.7) and control group (166.9). 11. Hematological values of FBF fed pigs RBC, hemoglobin, hematocrit and WBC were higher in the non-treated group, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were a little higher in the treated group. And all the above hematological values including differential count were within the normal range. 12. Effects of FBF addition as substitution for Fe injection for sucking pigs. (1) Daily feed consumption was larger by 10g in the treatment group (418g) than in the control group(408g). (2) Average daily weight gain was larger by 73.95g in the treatment group (296.98g) than in the control group (222.94g). (3) Feed efficiency was higher in the treatment group (1.41) than in the control group (1.83). (4) When the sucking pigs were fed liberally FBF as the substitute for Fe injection, there was relatively superior tendency to their growth and health conditions. 13. Production cost of FBF per kg (when the production cost of 1kg of FBF is fixed as 100 won) (1) Growing 0% ; 125.34 won, 3% ; 125.56 won, 5% ; 126.03 won and 10% ; 125.43 won (2) Fattening 0% ; 113.31 won, 3% ; 113.52 won, 5% ; 113.68 won and 10% ; 114.10 won As conclusion, making FBF with the abandoned briquette-ash and fish soluble results in lowering feed cost, increasing feed efficiency, increasing nutrient availability, decreasing pollution, saving the foreign currency used to import feed ingredients and increasing farmers income.
