This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

Objectives : The present study was conducted to determine whether administration of heat extracts of Sasunchungtyangeum has an inhibitory effect of neutrophil-derived oxidative injury following dermal scald burn in rats. Methods: Acute lung injury was induced by scald burn (15% of TBSA) in rats. To identify acute lung edematous lung injury, 5 hrs after skin burn, protein concentrations and numbers of polymorphonuclear leukocytes in bronchoalveolar lavage (BAL) were measured. In addition, levels of lung KC (neutrophil chemoattractant cytokine) and activities of lung myeloperoxidas (MPO) were measured, and morphological changes were observed. Results : Lung weight and concentration of BAL protein, the index of lung injury were clearly increased at 5 hrs postburn compared to them of sham. Administration of heat extracts of Sasunchunryangeum after scald burn inhibited the production of KC in lung tissue and decreased the activity of lung MPO related to influx of neutrophils. In histological changes, edematous lung injury with infiltration of inflammatory cells induced by skin burn were decreased by administration of heat extracts of Sasunchunryangeum after scald burn. Conclusions : These results suggest that Sasunchunryangeum may be a successful medical stuff in acute lung injury by skin burn.

외상성 교합으로 인한 어린이의 치주질환

최병재,고동현,김성오,이제호,손흥규 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.3

외상성 교합은 교합력의 결과로서 치주조직에 가해지는 손상이다. 주된 증상은 치아의 동요도이고, 통증, 타진에 민감, 열에 민감한 증상이 동반될 수 있으며 교합력에 의해 치아가 이동을 할 수도 있다. 만성으로 진행시 치아의 과도한 교모가 나타나며 방사선학적으로 치근막 공간의 비후, 치조백선의 비후, 치조골의 방사선 투과성, 치근흡수 등이 나타날 수 있다.외상성 교합은 치주질환의 원인과 관련되어 있다. 증가된 치아동요도를 야기하며 외상성 교합 자체는 치은염과 치주낭을 발생시키지 않으나 국소적 치태와 염증이 존재하고 있는 하에서 골소실, 치주낭이 발생할 수 있다. 치은퇴축은 외상성 반월, 맥콜스 팽윤, 스틸만 균열의 형태로 나타난다. 본 증례는 하악 유견치 부위의 치주질환을 주소로 내원한 5세 남아로서 상하악 유견치의 조기 접촉에 의해 하악 좌우측 유견치의 중증도의 동요도, 교합마모, 치은 퇴축, 치조골 파괴의 증상이 나타났기에 보고하는 바이다. Trauma from occlusion(TFO) is injury to the periodontal tissue as a result of occlusal forces. Mobility is a common clinical sign of occlusal trauma. In acute occlusal trauma, this may be accomanied by pain, tenderness to percussion, thermal sensitivity, and pathologic tooth migration. Chronic occlusal trauma may be marked by excessive wear and gingival recession. Radiographic finding include a widened periodontal ligament space, radiolucence and condensation of the alveolar bone, and root resorption. TFO is related to the pathogenesis of periodontal disease. It can cause increased tooth mobility. TFO itself does not initate or aggravate marginal gingivitis or initiate periodontal pockets. Active trauma can accelerate bone loss, pocket formation and gingival recession depending on the presence of local irritants and inflammation. Gingival recession associated with occlusal forces includes traumatic crescent, McCall's festoon and Stillman's cleft. TFO plays a minor role in the pathogenesis of early to moderate periodontitis. A 5-year-old male visited Yonsei University Pedodontics clinic with a chief complaint about gingival recession. Mobility, excessive wear, gingival recession were detected by clinical exam on the both mandibular deciduous canine. On the radiographic view, vertical alveolar bone loss was observed on both mandibular deciduous canine.

상처치유시 Antisense TGF-β1 Oligodeoxynucleotides가 Inducible Nitric Oxide Synthase발현 조절에 미치는 영향

최병민,곽현정,전창덕,임정식,박석돈,정헌택 大韓免疫學會 1996 大韓免疫學會誌 Vol.18 No.4

Wound healing in the skin may be complicated by both microbial invasion and inflammation. Following injury, platelet degranulation releases a number of chemotactic factors including transforming growth factor (TGF-fl) and platelet derived growth factor (PDGF). TGF-19 is a cytokines that modulates many cellular function and gene expression. However, it is not known whether TGF-P could regulate inducible nitric oxide synthase (iNOS) gene expression during wound healing. Here we report that down regulation of TGF-Q gene expression by antisense oligodeoxynucleotides increase iNOS during wound healing. Our reverse transcription- polymerase chain reaction (RT-PCR) result has shown that antisense TGF-fil oligodeoxynucleotides (ODN) targeting the TGF-J11 translation initiation region markedly reduced TGF-(il mRNA levels in wounded skin. Also, marked reduction in TGF-fl1 mRNA after antisense treatment invited that the increment of iNOS mRNA in wounded skin. Therefore, our irnmunohistochemical studies revealed a "pattern of iNOS product in wounded skin treated antisense TGF-fl1 ODN that was similar to the pattern of RNA synthesis detected by RT-PCR. In conclusion, our results indicated that the regulatory actions of TGF fl1 on iNOS. might be involved in the initiation and faciliates the resolution of inflammation following wounding.

문제: 조직병리검사의 처방이 복잡하고 전문화됨에 따라 오류처방이 빈번하게 발생되고 이를 해결하기위한 프로세스가 복잡하여 부서간의 갈등과 업무의 가중, 또한 병원 수입 감소가 초래되었다. 목적: 발생된 오류처방의 유형과 발생율, 오류처방을 해결하기 위한 프로세스를 파악하여 이에 대한 문제점을 개선하여 업무의 효율성과 관련부서간의 부가업무 감소와 갈등해소, 더불어 병원수익을 향상시키는 것에 목표를 두고 활동하였다. 의료기관: 서울시에 소재한 종합병원 질 향상 활동: 조직병리검사 처방의 오류처방 발생 원인과 유형, 발생율을 조사하여 원인을 파악하고 개선을 위한 프로세스를 구축하여 질 향상을 도모하였다. 개선효과: 수술실에서 의뢰한 외과 입원환자의 일반조직병리검사 오류율은 개선 전 7.8%에서 개선 후 3.5%, 동결절편조직검사 오류율은 개선 전 28.6%에서 개선 후 0%로 이전보다 모두 개선되었다. 또한 수술실 간호사의 업무 만족도는 일반조직병리검사의 처방시 95%, 동결절편조직검사 처방시 90%로 높은 만족도를 보였다. 단 병리과의 경우 업무가 증가됨에 따라 초과근무시간이 증가하였다.

DCT를 이용한 영상의 윤곽선 추출을 위한 양자화 테이블 비교분석

최현주,성병우,최흥국,서재현 인제대학교기초과학연구소 1998 자연과학 Vol.2 No.-

본 논문에서는 DCT(discrete consine transform)를 이용하여 영상 데이터를 공간 영역에서 주파수 영역으로 변환하여 주파수 영역별로 분해한 뒤, 윤곽선 추출과 압축을 동시에 하기 위한 여러 양자화 테이블을 적용하고, IDCT(Inverse DCT)를 이용하여 복원한 결과를 비교 분석함으로써, 보다 정확한 윤곽선을 가진 영상을 추출할 수 있는 양자화 테이블을 구했다. 이 양자화 테이블을 DCT 처리된 영상에 적용했을 때 윤곽선과 압축 효과를 가진 영상을 얻을 수 있었다. In this paper, we transform image data from spatial domain to frequency domain using DCT, decompose it into each frequency band. We apply various quantization table for edge detection and compression simultaneously. We researched a quantization table for extracting image with exact edge, as compare and analyze restored images using IDCT. When we applied this quantization table to the DCT transformed image, acquired the image with edge and compression effect.
