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.

A-59-year old man was admitted to the hospital with a 2-month history of the right pleuritic chest discomfort and mild dyspnea. Seven years earlier, he was operated on left pneumonectomy for squamous cell carcinoma of left upper lobe (Stage IIb, $T_2N_1M_0$). The computed tomographic scan revealed an anterior herniation of the right lung in the left hemithorax. A single thorax after receiving pneumonectomy is called a "buffalo chest" because the absence of an anatomical separation of the two hemithoraxes resembles that of the North American buffalo or bison. A possible pneumothorax should be catastrophic for the patient, so he should be closely monitored regarding any invasive procedure or trauma. He improved after symptomatic treatment.

Chronic expanding hematoma of the thorax is a specific subtype of the chronic empyema. It presents as a slowly expanding intrathoracic mass which result in dyspnea or recurrent hemoptysis. The symptoms develop months or years after tuberculous pleurisy, trauma or surgery. Usually, it shows three common findings: a giant mass lesion in the thorax, some surrounding calcifications, the absence of signs or symptoms of infection. We report a case of chronic expanding hematoma of the thorax, initially presenting as massive hemoptysis through bronchopleural fistula which resulted in radiologic findings of new air-fluid level within the previous pleural lesion filled with unknown materials.

A chronic expanding hematoma (CEH) in the thorax is a rare and specific condition of chronic empyema. CEHs in the thorax are often associated with tuberculosis and/or previous surgical procedures. While the incidental detection of a pleural mass and dyspnea are common clinical manifestations, a few cases present with hemoptysis. We encountered a case of CEH in the thorax. This case is unique in that it developed without a prior history of tuberculosis or surgery and presented with massive hemoptysis accompanied by bronchopleural fistula. We report the third case of CEH in the thorax in Korea with a summary of the clinical characteristics of previous cases.
