The purpose of this study is to examine quantitatively the relations between the girdle pressures operated on the abdomen and buttock of body according to the increase of time and the displacement or the deformation of thorax, diaphragm, heart and stomark caused. In an erect position, the roentgen photographs of thorax and abdomen were taken on three female subjects (20~21 years old) with eutonic stomach under four different time sequence (0, 3, 6, 9 hours) of the girdle pressure. The displacement and deformation of each viscera were examined by X-ray films thus obtained. The results are as follows: 1. Thorax was not statistically significant according to the increase of time in the girdle pressure. 2. Diaphrame greatly ascended under the increase of time in the girdle pressure after 9 hours, put pressure upon the lung and heart. 3. Heart increased in the height of maximum transverse-diameter, of the left side because of ascending of diaphragm.

Traumatic asphyxia is a distinctive clinical syndrome characterized by cervicofacial cyanosis and edema, bilateral subconjuctival hemorrhage, and multiple petechiae of the face, neck, and upper part of the chest after a severe compressive crush injury of the thorax or of the upper part of the abdomen.The pathophysiologic mechanism of traumatic asphyxia is reflux of blood from the heart retrograde through the valveless superior vena cava and the great veins of the head and neck by severe compression of the thorax or the abdomen.We experienced one case of the traumatic asphyxia, and its clinical features are discussed.

New USNCAP has been carried out by NHTSA including front and side crash from MY2011. In this paper, test results for USNCAP Side crash were reviewed by statistical analysis. This review focused on side crash test results to investigate the effect of changes from new USNCAP side crash test protocol among 30 passenger cars. These results were summarized as followings. Total number of 5 star vehicles on the front seat dummy (16 vehicles, 53.3%) was slightly smaller than the rear seat's (17 vehicles, 56.7%) in MDB test. For the ES-2re dummy, chest injury, ie maximum rib deflection contributed to 66% in the mean value of $P_{joint}$. Pelvis injury was highly dependent upon performance up to 87% in the SID-IIs dummy cited on the rear seat in average $P_{joint}$. For Pole test, pelvis injury made contribution to the average performance to 83%. For standard deviation, it showed the largest value in the same body region as the mean value for each dummy. Overall front seat performance showed 14 vehicles, 44.6% with 5 star vehicles less than each MDB or Pole test result. This result showed that performances in MDB test were different pattern to Pole test on driver position. Number of 5star vehicles for overall side NCAP performance are 18 passenger cars (60%). Curtain airbag and driver thorax airbag were equipped in all test vehicles. One vehicle is equipped with thorax airbag in the rear seat. Results from two side tests considered as reliability problem, ie the cause for large standard deviation in side crash test. Consequently, the countermeasure for new USNCAP side crash test is essential to design the effective side structures for side collision and to control well dummy kinematics with curtain and thorax airbag in order to reduce chest and pelvis injuries.

Most clinicians have taken a lot of interest in tumors arising from the bony thorax because not only of their rarity and predictable diagnosis which could be reflected as a unique radiologic shadow but also variable surgical modes for maintenance of chest wall stability encountered after en-bloc resection. By the retrospective review, we have analyzed 24 cases of primary bony thorax tumors which were experienced and surgically treated at the St. Mary`s hospital of Catholic Medical College from Jan. 1969 to Sept. 1984. The results are as follows: 1. Age incidence was evenly distributed through all decades and the male-female ratio is 15:9. 2. 16 cases out of 24 were benign tumors and the commonest one of which was fibrous dysplasia. 3. Remaining 8 cases were malignant tumors and among which osteogenic sarcoma was the commonest one. 4. The majority of tumors [22/24] were developed from the rib and the remains were from the sternum. 5. Common manifestation were palpable mass or swelling and localized tenderness. 6. Various kinds of operative procedure were underwent: single resection of rib including tumor,14 cases; multiple resection of ribs with chemotherapy or myoplasty, 2 cases; en-bloc resection of the chest wall and reconstructive procedure, 5 cases; partial resection of sternum, 1 case; bone biopsy and chemotherapy, 2 cases.

Different proliferation of neuroblast 6-4 (NB6-4) in the thorax and abdomen produces segmental specific expression pattern of several neuroblast marker genes. NB6-4 is divided to form four medialmost cell body glia (MM-CBG) per segment in thorax and two MM-CBG per segment in abdomen. As homeotic genes determine the identities of embryonic segments along the A/P axis, we investigated if temporal and specific expression of homeotic genes affects MM-CBG patterns in thorax and abdomen. A Ubx loss-of-function mutation was found to hardly affect MM-CBG formation, whereas abd-A and Abd-B caused the transformation of abdominal MM-CBG to their thoracic counterparts. On the other hand, gain-of-function mutants of Ubx, abd-A and Abd-B genes reduced the number of thoracic MM-CBG, indicating that thoracic MM-CBG resembled abdominal MM-CBG. However, mutations in Polycomb group (PcG) genes, which are negative transregulators of homeotic genes, did not cause the thoracic to abdominal MM-CBG pattern transformation although the number of MM-CBG in a few percent of embryos were partially reduced or abnormally patterned. Our results indicate that temporal and spatial expression of the homeotic genes is important to determine segmental-specificity of NB6-4 daughter cells along the anterior-posterior (A/P) axis.

전폐절제술후 주변 해부학적 구조물들에 의하여 전폐절제술후 증후군 증상이 드물게 나타난다. 전폐절제술후에는 경미한 호흡 곤란을 보이거나 전폐절제술후 증후군처럼 중증의 증상을 나타낸다. 전폐절제술쪽 흉곽으로 폐가 탈출되어 단일 흉곽소견(Buffalo chest)이 보이는 경우, 외상 또는 침습적 시술에 있어 각별한 주의가 요구된다.

흉강 내에 발생하는 만성 팽창성 혈종은 매우 드문 질환이다. 저자들은 20년 전 결핵성 늑막염을 앓고 난 뒤 반복적인 객혈로 3개월 전부터 외래 추적 관찰하던 노인에서 갑작스런 대량 객혈과 함께 이전 방사선 소견에서 병변을 가득 채웠던 물질이 새롭게 발생한 기관지 흉막루를 통해 소실되어 공기 액체층이 새롭게 형성된 일련의 변화를 통해, 내부 성분이 혈액임을 확인하여, 병변이 만성 팽창성 혈종임을 진단하였기에 문헌 고찰과 함께 보고 하는 바이다.

저자들은 대량 객혈로 발현한 흉곽 내 만성 팽창성 혈종 1예를 보고한다. 이 증례는 이전의 증례와 달리 결핵성늑막염이나 흉부 수술, 외상의 과거력 없이 자연 발생한 증례라는 점에서 의의가 있다. 또한 무증상, 호흡곤란 등으로 발현했던 대부분의 증례와는 달리 드물게 대량객혈로 발현하였으며, 이러한 대량객혈이 기관지흉막루를 동반하여 발생하여 기관지동맥 색전술과 수술로 치료되었다는 점에서 특징적이다. 증례보고와 함께 문헌고찰을 통해 과거 보고된 흉곽 내 만성 팽창성 혈종의 임상양상에 대해 표로 정리하였다.

목 적 : 다양한 치료 부위에 따라 MVCT(Megavoltage computed tomography)를 이용하여 치료 중(Intrafraction), 치료 간(Interfraction)의 장기 위치 변화를 측정하여 평가하고자 한다. 대상 및 방법 : 본 연구에서 두 경부(Head & neck), 흉부(Thorax), 간(Liver), 전립선(Prostate) 종양을 가진 48명 환자들은 전체 치료 과정동안 다양한 MVCT scan을 시행하였다. 평균 환자 당 60개의 MVCT 영상을 획득하여 분석하였다. 결 과 : 치료 간(Interfraction)오차는 흉부와 복부 그리고 골반이 종 방향(Longitudinal, Y)에서 3 mm 이상의 차이를 보였다. 치료 중(Intrafraction) 변화를 알아보기 위해 치료가 끝난 후에 MVCT를 찍어 확인한 후 치료 중(Intrafraction) 움직임 차이는 종 방향에서 2 mm 내외로 나타났다. 또한 치료 전과 후의 움직임의 변화로 인해 치료 간 그리고 치료 중의 차이를 확인하였다. 결 론 : 본 연구에서도 두 경부(Head & neck), 흉부(Thorax), 간(Liver), 전립선암(Prostate cancer) 환자들의 치료 간(Interfraction) 변화와 치료 중(Intrafraction)변화를 통해 적절한 고정 기구와 표적 여백의 윤곽을 완성하는데 도움이 될 거라 사료된다.
