The Organ Injury Scaling Committee of the American Association for the Surgery of Trauma recently published a consensus classification of hepatic and splenic injuries. The hepatic and splenic injury scales, based on parenchymal laceration and intrahepatic hematoma, include grade 1 to 6 and grade 1 to 5 respectively, representing the least to most severe injury. Forty-eight patients with hepatic and splenic injury were evaluate by abdominal CT from January 1995 to May 1996 and we compared abdominal CT grading with operative grading. Four CT grades did not correlate with operative finding. CT grading showed a sensitivity of 80%, specificity 80% in regard to operative grading. We conclude that 1) CT is an accurate technique to determine the extent of hepatic and splenic injury. 2) CT grading of hepatic and splenic trauma has a high correlation with operative grading.

기존의 방법을 일부 수정하여 뇨중 3-methylhistidine을 분석하였다. 뇨중 3-methylhistidine을 fluorescamine 유도체화하여 HPLC에 주입하고 C_18 column과 10 mM acetonitrile/sodium phosphate buffer(pH 7.5)로 분리·용출시켜 형광검출기로 측정하였다. 3-methylhistidine의 체류시간은 7분 이내이었으며, histidine과의 분리상태도 서로 간섭함이 없이 양호하였다. 뇨에 3-methylhistidine을 첨가하고 이를 분석하였을 때의 회수율은 93∼106%로 높은 수준이었다. 체육학과 남학생중 웨이트 트레이닝 단련자와 비단련자를 대상으로 조사한 단기간의 웨이트 트레이닝에 따른 뇨중 3-methylhistidine 함량의 변화는 두 집단 모두 웨이트 트레이닝후의 3-methylhistidine 분비량이 유의하게 증가하였다. A modified method is given for the precolumn derivatization and subsequent high-pressure liquid chromatographic seperation of 3-methylhistidine from urine. The elution contained isocratic solution with acetonirile and 10 mM sodium phosphate(pH 7.5) requires less than 7 min. The recoveries of 3-methylhistidine from urine control were 93% to 106%. 3-Methylhistidine determinations were performed on urine samples from volunteers who were both male trained and non-trained physical undergraduates. As the result, urinary 3-methylhistidine content of volunteers increased significantly after weight training.

Most of closed fractures of the tibial shaft can be treated successfully with medullary nails. Reamed intramedullary nailing technique has become a good alternative method in treating the close tibial fracture. Unreamed interlocking intramedullary nailing has been employed successfully in the treatment of open tibial fractures. This study was undertaken to evaluate the result of interlocking intramedullary nailing without reaming in the treatment of closed fractures of the tibial shaft. From 1995 through 1998, fifty four cases of the closed, displace tibial fractures were treated by an unreamed intramedullary nailing and the average follow-up period was 1 year and 5 months(ranged from 12 months to 27 months). The results were as follows : 1. Fifty four cases were treated with closed, unreamed nailing technique and the nail which has 1mm smaller diameter than isthmic width of unaffected tibia was choosen. 2. The average time to bony union was achieved at 17 weeks without abundant periosteal b callus formation. 3. Eight tibiae were required the additional procedure such as autogenous bone graft, skin graft or local skin flap. We also have observed the screw breakage of ten tibiae but there were no intraoperative jamming or incarceration and no significant complicaton such as bending or breakage of the nail, shortening or non-union of the fractures. In conclusion, unreamed technique is an attractive method to treat the close, displaced fractures of the tibial shaft. 경골 간부 골절의 치료에 있어서 견고한 내 고정으로 조기 관절운동 및 체중 부하를 통해 골절 유합 및 기능 회복을 도모할 수 있는 골수강내 금속정 고정술이 널리 사용되어지고 있다. 골수강내 금속정술의 장점은 술 후 조기 관절운동과 체중 부하가 가능하여 이환율(morbidity)을 감소시키며 불유합의 발생률이 낮아는 것이다. 경골 간부 골절의 치료에 있어서 비확공성 금속정 고정술은 주로 심한 연부 조직 손상을 동반한 골절 및 개방성 골절의 치료에 적용되어지고 있으며, 대부분의 폐쇄성 경골 간부 골절의 치료로는 골수강 확공 후 골수강을 충만시키는 금속정을 삽입하는 확공정 금속정 고정술이 시행되어지고 있는 경향이다. 저자들은 폐쇄성 경골 간부 골절에 대해서 비확공성 금속정 고정술의 유용성 여부를 알아보기 위해서 동국대학교 의과대학 정형외과학교실에서 치료했던 54례를 평균 1년 5개월 추시하여 골 유합 기간, 합병증의 발생에 대해서 분석하였다. 본 연구에서 비확공성 금속정 고정술시 골 유합 기간은 확공성 금속정 고정술시와 비교하여 유의한 차이가 없음을 알 수 있었으며, 확공을 하지 않음으로써 발생할 수 있는 jamming이나 가는 직경의 금속정을 선택함으로써 우려되는 금속정의 휨, 부러짐 등의 합병증은 발생하지 않았다. 결론적으로 폐쇄성 경골 간부 골절의 치료에 있어서도 비확공성 골수강내 금속정 고정술은 유용한 방법으로 사료된다.

흰쥐 편도체에서 칼슘결합단백인 calbindin-D28K함유 신경세포의 생후 발달에 관한 면역조직학적 연구

정윤영,김종중,문정석,박영란,정상봉,김현곤,박상수 조선대학교 2001 The Medical Journal of Chosun University Vol.26 No.1

Background and Objectives : The calcium-binding protein, calbindin-D28K(CB) is widely distribution of CB in rat amygdala during postnatal maturation, in order to provide an insight into the developmental role it may play in the amygdaloid neurons. Materials and Methods : The present study is based on 28 postnatal cases ranging from the day of birth, postnatal day 0 (P0) to 30 days (P5, P10, P15, P20, P30), and these cases were compared with adult rat amygdala. Cryostat sections processed free-floating with monoclonal antibody by immunohistochemistry. Results : CB-immunoreactive neurons were already found at birth in all amygdaloid nuclei except the intercalated nucleus. The intensity and number of immunoreactivity of CB-containing neurons increased during the first 10 days of postnatal life but dramatically decreased at P15. Mature patterns of CB-immunoreactive neurons were achieved at P20. In the adult amygdala, CB-immunoreactive neurons were distributed in almost all amygdaloid nuclei except the intercalated nucleus. Conclusion : The present results show early appearance of CB immunoreactivity in the amygdala. It may be related to the early appearance of CB immunoreactivity in many other brain regions, and suggests that CB may play a functional role during the development of the nervous system including amygdala.

As human become aged, he become color weak due to yellowed eye sight. The 87% of information for human behavioral decisions are visually perceived. Therefore, the color weakness will affect his behaviors in many ways. Most of previous research regarding color planning for the aged people focuses on discovering their preferred colors and reflecting the colors on facility color planning. But these research failed to identify confused range of color cognitions due to the color weakness of the aged. In this research, targeting the aged in multi-purpose senior centers, we analyze their color distinctions and confusions using computer graphic tools. Our research discovers several important points. First, there are differences in color cognitions between the young facility designers/staffs and the aged facility residents. Second, these differences lead to the differences in the abilities of spatial cognitions between the young and the aged. Third, the difference in the spatial distinctions if mainly caused not by color itself but by color adjacencies. Based upon these findings, we propose that color planning of facilities for the aged be made not from the view of the designers but from the view of the aged, considering yellowed eye sight of the aged.
