  • There are relatively many reports have been issued on he active movement of cuticle of larva. which tend to protect their body, however, only a few reports have been disclosed on the cuticle of pupal body except the small portion of rectangle which shown tortoise-shell shape. In this connection, many portion of the external structure of pupal cuticle has been studied and the following. results were found: 1) No. spot of rectangle which is sculptured in the surface of cuticle that born by branching. out of the development of cell in imaginal bud of antenna and head were found. However, in the compound eye of net shaped sculpture was found in the (equation omitted) shaped parts which holding. the diameter of about 8u and the surrounding area has the small bump and the one is dark brown coloured comparing with shape. 2) The sculpture shape of thorax is a little different than in the head. However, (equation omitted) portion is varies from the segment to segment. In general, it is not very clear than the compound eye in the head, the dark brown bump shape is slowly fade a from the prothorax, mesothorax to metathorax. 3) The surface of intersegment membrane is colourless or slightly yellow, and the entire surface has stripped marking with thine lines. 4) In the abdominal segment, there are many and small sculptures in net shape around the (equation omitted) shape portions. 5) The size of sculpture in (equation omitted) portion of abdomen is smaller than one in thorax, and in the same segment, the dorsal is smaller than abdomen and the rear portion of the segment is larger than the front of segment. 6) After the 7th abdominal segment, no intersegmental membrane is found and the cuticle of the external structure is the same as external structure of the segment. 7) The seta is not found in head, compound eye, antenna and wing which portions were subdivided by development of imagined bud of the cell, no seta is found in cuticle of the segment in the general cell of the larva stage and also in the dorsal and intersegmental membrane.

  • Backgroun : The long-term survival after operation of patients with lung cancer invading the chest wall is known to be related to regional nodal involvement, completeness of resection and depth of chest wall involvement. In this study results of complete resection are reviewed to determine survival charateristics. Material and Method: Of 680 consecutive patients who were operated on for primary non-small cell carcinoma between 1988 and 1998, we retrospectively reviewed 55 patients(8.0%) who had complete resection for lung cancer invading the chest wall or parietal pleura. Result: Resection of the chest wall was on bloc in 29 patients(47.3%), and extrapleural in 26(52.7%). In the patients undergoing extrapleural resection, the depth of chest wall invasion was confined to the parietal pleura in all patients(100%). In the patients underging en bloc resection, the pathologic depth of invasion was into the parietal pleura alone in 9(31.0%) and into the chest wall in 20(69.0%). The follow-up rate of these patients was 100%. Hospital mortality was 5.4%(n=3). The actuarial 5-year survival rate was 26% for all hospital survivors(n=52). The actuarial 5-year survival rate of patients with T3N0M0 disease(29%) was better than that of T3N2M0 disease(18%), however, there was no significant(p=0.30) difference. The depth of chest wall invasion had no statistically significant effect on survival in our series, neither for patients with involved lymphatic metastasis nor for those without(p=0.99). Conclusion: These observations indicate that the good five year survival in patients with T3 NSCLC invading the chest wall resulted from complete resection. Survival of patients with lung cancer invading the chest wall after complete resection is dependent on the extent of nodal involvement and much less so on the depth of chest wall invasion.

  • The records of 10 patients with traumatic diaphragmatic hernia seen from November 1977 through July 1987 were reviewed. All the patients had a transdiaphragmatic evisceration of abdominal contents into the thorax. We treated 7 male and 3 female patients ranging in age from 3 to 62 years. In 8 patients, diaphragmatic hernia followed blunt trauma and in 2 patients, stab wounds to the chest. The herniation occurred on the right side in 3 patients and on the left side in 7. All the patients sustained additional injuries: rib fractures [7 patients], additional limb, pelvic and vertebral fractures [6], closed head injury [2], lung laceration [1], liver laceration [1], renal contusion [1], ureteral rupture [1], and splenic rupture [1]. Organs herniated through the diaphragmatic rent included the omentum [6 patients], stomach [4], liver [4], colon [3], small intestine [1], and spleen [1]. For right-sided injuries, the liver was herniated in all 3 patients and the colon, in 1. in the initial or latent phase, dyspnea, diminished breath sounds, bowel sounds in the chest were noted in 4 patients, and in the obstructive phase, nausea, vomiting, and abdominal pain were found in all 3 patients. Two patients had a diagnostic chest radiograph with findings of bowel gas patterns, and an additional 8 had abnormal but nondiagnostic studies. Hemothorax, pleural effusion or abnormal diaphragmatic contour were common abnormal findings. Three patients were operated on during the initial or acute phase [immediately after injury], 4 patients were operated on during the latent or intermediate phase [3 to 210 days], and 3 patients were operated on during the obstructive phase [10 to 290 days]. Six patients underwent thoracotomy, 2 required thoracoabdominal incision, and 2 had combined thoracotomy and laparotomy. Primary suture was used to repair the diaphragmatic hernia in 9 cases. One patient required plastic repair by a Teflon felt. Empyema was the main complication in 2 patients. In 1 patient, the empyema was treated by closed thoracostomy and in 1, by decortication and open drainage. There were no deaths.

  • A hexapod walking robot had been developed for gathering information in the field. The developed robot was $260{\times}260{\times}130$ ($W{\times}L{\times}H$, mm) in size and 14.7 N in weight. The legs had nineteen degrees of freedom. A leg has three rotational joints actuated by small servomotors. Two servomotors placed at ankle and knee played the roles of vertical joint for up and down motions of the leg and the other one placed at coxa played the role of horizontal joint for forward and backward motions. In addition, a servomotor placed at thorax between the front legs and the middle legs played the role of vertical joint for pumping the two front legs to climb stair or inclination. Walking motion of the robot was executed by tripod gait. The robot was controlled by manual remote-controller communicated by an infrared ray. Two controllers were equipped to control the walking of the robot. The sub-controller using PIC microcomputer (Microchips, PIC16F84A) received the 16 bit command signal from the manual remote controller, decoded it to 8bit and transmitted it to the main microcomputer (RENESAS, SH2/7045), which controlled the 19 servomotors using the PWM command signals. Walking speeds were controlled by adjusting the period of command cycle and the stride. Forward walking speed were within 100 cm/min to 300 cm/min. However, experimental walking speed had the error of 4-40 cm/min to compare with the theoretical one, because of slippage of the leg and the circular arc motion of servomotor of coxa.

  • Background: Ewing sarcoma is a small round cell tumor arising from soft tissue and bone that predominantly affects children and adolescents. The most unfavorable prognostic factor is the presence of distant metastasis at the time of diagnosis. Materials and Methods: The records of 26 Ewing sarcoma patients (14 male, 12 female) were re-evaluated retrospectively. Results: The median age was 26.5 (19-42) years. Eight patients (31%) showed a primary tumor in their extremities, 8 (31%) in the thorax, 4 (15%) at the vertebra, 4 (15%) in the head and neck, and 2 (8%) in the abdomen. Five patients (19%) had distant metastasis at diagnosis. The median progression-free survival was 72 months and 10 months in localized and metastatic disease, respectively (p=0.005). The overall survival rate was 19 months in metastatic disease, and the 5-year overall survival rate was 64% in localized disease (p=0.006). Patients who had localized disease in the extremities and were under age 30 had a favorable prognosis. Conclusions: Although Ewing sarcoma is a tumor affecting children and adolescents, it may be seen in adults, where the prognosis is generally worse. Although it is a highly malignant tumor, it is possible to achieve improved survival with combined modality treatments.

  • The aim of the present research was to establish primary characteristics of electron beams for a Varian 2100C/D linear accelerator with recently developed PRIMO Monte Carlo software and to verify relations between electron energy and dose distribution. To maintain conformity of simulated and measured dose curves within 1%/1mm, mean energy, Full Width at Half Maximum (FWHM) of energy and focal spot FWHM of initial beam were changed iteratively. Mean and most probable energies were extracted from validated phase spaces and compared with related empirical equation results. To explain the importance of correct estimation of primary energy on a clinical case, computed tomography images of a thorax phantom were imported in PRIMO. Dose distributions and dose volume histogram (DVH) curves were compared between validated and artificial cases with overestimated energy. Initial mean energies were obtained of 6.68, 9.73, 13.2 and 16.4 MeV for 6, 9, 12 and 15 nominal energies, respectively. Energy FWHM reduced with increase in energy. Three mm focal spot FWHM for 9 MeV and 4 mm for other energies made proper matches of simulated and measured profiles. In addition, the maximum difference of calculated mean electrons energy at the phantom surface with empirical equation was 2.2 percent. Finally, clear differences in DVH curves of validated and artificial energy were observed as heterogeneity indexes were 0.15 for 7.21 MeV and 0.25 for 6.68 MeV. The Monte Carlo model presented in PRIMO for Varian 2100 CD was precisely validated. IAEA polynomial equations estimated mean energy more accurately than a known linear one. Small displacement of R50 changed DVH curves and homogeneity indexes. PRIMO is a user-friendly software which has suitable capabilities to calculate dose distribution in water phantoms or computerized tomographic volumes accurately.

  • Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and acounts for 6% to 15% of all cases of childhood cancer, Rhabdomyosarcoma in seventh most common form of childhood neoplasms, following acute leukemia, tumors of the central nervous system, lymphoma neuroblastoma, Wilm`s tumor, bone tumor. Rhabdomyosarcoma can arise anywhere in the body, but primary site in the thorax is relatively rare. We experienced a case of aveolar rhabdomyosarcoma arising from intercostal muscle, A 12 year-old woman was suffered from the intermittent left chest pain radiating to the scapular area and dyspnea, On physical examination, pulmonary friction rub was heard on the left upper lobe area. Qn adimission, the chest simple radiography revealed a 7 x 6, 5cm sized radio-opaque mass with pleural effusion in the superior mediastinum and the CT showed a well difined radio-opaque mass including the destructed 2nd rib and pleural effusion. The percutaneous tra-nsthoracic needle aspiration biopsy was likely to show blastoma. After the chemotherapy[vincristine, actinomycin-D, cyclophosphamde] was done to treat blastoma, the pleural effussion was subsided and the mass was slightly decreased by 4.5x 4. 5cm. For treatment and diagnosis, we performed en-bloc resection and the defected chest was reconstucted with Gortex patch. Grossly, the specimen was colored graysh-white and arised in between two ribs The microscopic findings showed that the tumor cells were small round with scant pinkish cytoplasm on the H-E stain and the tumor cell nests were grouped by reticulum fibers and showed alveolar pattern on the silver stain The electromicroscopic finding presented that the cytoplasm contained tangled fibrillar and flocculent materials. The histopathologic findings were compatable with laveolar rhabdomyosarcoma. She was discharged without any complication. After discharge, she has been treated with radiation theraphy and chemotheraphy, and not recurred untill last follow-up We report a case of alveolar rhabdomyosarcoma arising to intercostal muscle, developed in 12 year-old waman, with brief review of literatures.

  • Malignant fibrous histiocytoma(MFH) is a deep-seated pleomorphic sarcoma, which occurs principally as a mass of the extremities, abdominal cavity, or retroperitoneum in adults. However, it only rarely occurs in the chest wall. An 85-year-old man had undeergone excision of a small mass on the right posterior chest wall under local anesthesia 14 months age. However, the lesion did not heal and the mass recurred. He was referred to our hospital after the mass had grown to a size of 10.5$\times$8$\times$4cm with a 3$\times$3cm skin defect. Intraoperative frozen biopsy revealed MFH. An en-bloc wide resection and thin-thickness skin graft from his thigh were performed. Although distant metastasis to the lund developed 14 months later and the patient died 2 months later, there was no local recurrence. Thin-thickness skin graft is a simple method for a wide range skin defect, especially in the old age. He recovered in good condition without any physical disabilities.

  • Metatropic dysplasia is a rare spondylo epi metaphyseal dysplasia characterized by progressive kyphoscoliosis, short limbs with relatively large hands and feet and limited of motion and enlargement of the large joints. It is diagnosed based on the characteristic clinical and radiological features. Even though benign cases of this disease are frequently reported, metatropic dysplasia can often have a fatal outcome. We describe a sporadic case of the well-delineated lethal metatropic dysplasia.

  • The medical records of 69 dogs with history of bite wounds, between 1998 and 2006, were reviewed. Information obtained from these files included the general statistics of the patients (sex, age, breed, weight), season on occurrence of injuries, body areas wounded, therapeutic regime used and mortality rates. Intact male dogs were more frequently bitten. The weight distribution of the bitten population was varied 41% for small, 16% for medium and 17% for large dogs. The highest incidence was in young animals. The distribution of bite wound injuries over the year was recorded with peaks in April (13%), March (12%), August (12%) and September (10%). The common regions of injury were the head (22), fore-limbs (17), hind-limbs (15), abdomen (15), thorax (15) and neck (14). Mortality tends to be increased in cases of thoracic or abdominal injury. The results about the prevalence of bite wounds in Daejeon and Chungnam area are intended to use as a reference data in veterinary practice.
