출혈성 위궤양이 병발한 식도열공 허니아의 치험례

정원상 대한흉부심장혈관외과학회 1983 Journal of Chest Surgery (J Chest Surg) Vol.16 No.3

One case of surgically treated sliding esophageal hiatal hernia associated with bleeding gastric ulcer is presented. The patient was 73 years-old woman who had suffered from epigastric heartburn, indigestion, and melena since 3 months prior to admission. Esophageal hiatal hernia was suspected on the simple chest film and the diagnosis was confirmed by tetralogic barium study of the gastrointestinal tract. Hematemesis and melena were persisted so emergent thoracotomy and abdominal exploration were undertaken. Repair of hiatal hernia by constricting suture around relaxed esophageal hiatus was made and plication sutures were Inserted between esophagogastric junction and median arcuate ligament of diaphragm. Concomittently, subtotal gastrectomy with Billroth II procedure was performed to removal of large bleeding ulcer on the lesser curvature of the stomach antrum. Postoperative course was uneventful.

A clinical analysis was performed on 97 cases of chest injuries experienced at Department of Thoracic and cardiovascular Surgery, Armed Forces Capital Hospital during 2 years period from 1986 to 1988. Of 97 patients of chest trauma, 39 cases were result from penetrating injuries whereas 58 cases were from non-penetrating injuries, and there were 77 cases of hemothorax and / or pneumothorax, 47 of rib fracture, 8 of foreign body, 6 scapular and clavicle fracture, 5 of diaphragmatic injuries, 4 of paraplegia. The majority of chest injuries were encounted in the age group between 21 and 30 years-old, mean age was 25.9 years-old and all cases were male except one. Gun-shot wound was the most common cause in the penetrating injuries and the majority of non-penetrating chest injury patients were traffic accident and fist or kick accounted for next. The principles of therapy for chest trauma were rapid expansion of the lung by closed thoracostomy[45 cases] and thoracentesis only[3 cases] but thoracotomy done at 27 cases because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic injury and bronchial rupture. The over-all mortality was 2.07 percent[2 cases among all], a case was from penetrating injuries and another was from non-penetrating injuries.

폐이식의 실험적 쥐모델

정원상 한양대학교 의과대학 1998 한양의대 학술지 Vol.18 No.2

In studies concerning lung transplantation, the dog has been used as the main experimental animals, chiefly historical reasons, but also because lung transplantation in smaller animals is technically more difficult. But as above mention, organ transplantation in the rats was made possible by development of microsurgery and anesthesia in the last two decade, pioneered by Dr Lee. And also was due to the availability of very thin suture materials(8-0, 9-0, 10-0 ethicon or nylon suture etc). But, the intensive training needed for microsurgical training is illustrated by steadily improving perioperative survival in the course of our experiment.

국내에서 심장, 폐이식이 각 대학병원에서 점차 확산 시행되고는 있으나, 이에 따른 기초실험이 뒷받침되지 않고, 큰 동물에서는 많은 실험비용이 들어 보다 적은 동물을 이용하게 되었으나 이 방법은 현미경하의 미세수술기법의 발달과 더불어 발전하게 되었다. 본 연구는 현미경하의 미세수술기법으로 쥐모델에서 복부의 대동맥과 하공정맥에 다른 쥐의 공여심장의 대동맥과 폐동맥을 각각 문합술로 연결하는 방법으로 이식하여 동종이형의 장기이식에 따른 거부반응과 면역억제제를 투여하여 그에 따른 생존율을 비교하고자 하였다. 체중 150∼250 gm의 흰쥐의 심장을 공여 및 이식하는 바, 이소성의 심장이식후 면역억제제를 투여하지 않은 군과 면역억제제를 투여한 군으로 나누고, 각 군에서 복부에 이식된 심장의 박동을 매일 만져보고서 만져지지 않을 경우는 이식된 심장이 거부반응에 따른 것으로 판단하여 이의 생존율을 비교 검토하여본 바, 면역억제제를 투여하지 않은 군에서보다 투여한 군에서 오래 생존하여 동종이형의 이식에서 면역억제제를 투여하므로써 장기이식에 따른 장기성적을 향상시킴을 알 수 있었다. In 1964, Abbott and Colleagues published the world's first heterotopic heart transplantation technique in the rat. Their method established circulation by end-to-end anastomoses of the graft's aorta and pulmonary artery to the recipient's abdominal aorta and Inferior Vena Cava(IVC), respectively. In 1966, Tomita et al altered Abbott's technique by employing end-to-side rather than end-to-end anastomoses, thus eliminating the hind leg paralysis that sometimes resulted from Abbott's technique. In order to prevent postsuture hemorrhage (since 7-0 silk suture was the finest available at that time), Tomita's aortic anastomosis was done with double up-and-down continuous suture technique. A single layer continuous anstomosis effected the pulmonary artery-IVC anastomosis. The availability of Nylon monofilament suture made it possible for Ono and Lindsey to use a single layer suture technique for the aortic end-to-side anastomosis in their modified rat heart transplantation. We observed survival time between control group and Immunosuppression(Cyclosporine administration, 10mg/Kg${\times}$4 times postoperatively) group after heterotopic heart transplantation in the rat model. The cyclosporine adminstration group survived longer than the control group, thus we concluded that cyclosporine was based on Immunosuppressive drugs.

The study was designed to investigate the effects of a 12-week combined exercise training on physical fitness, isokinetic function, and IGF-1 in elderly women with sarcopenic obesity. Twenty elderly women with sarcopenic obesity were randomly assigned to one of following two groups, i.e., combined exercise group (EG: n=10) and control group (CG: n=10). The subjects in the EG completed 60~80 min of exercise training for three times a week during 12 weeks, whereas the subjects in the CG group were asked to maintain their normal lifestyle during the same period of the intervention. Main results of the present study were as follows: First, Regarding body composition, body weight, BMI, % fat mass, and free fat mas improved significantly in the EG. Second, Regarding physical fitness, grip strength, upper arm flexion, chair sit to stand and VO2max increased significantly at the EG. Third, Regarding isokinetic function, peak torque, total work and average power at extension and flexion increased significantly at the EG. Fourth, IGF-1 increased significantly at the EG. Based on the results, it was concluded that the 12-week combined exercise training would contribute on improving body composition, physical fitness, isokinetic function, and IGF-1 in elderly women with sarcopenic obesity. 본 연구의 목적은 12주간의 복합운동이 근감소성 비만 노인 여성의 체력, 등속성 근기능 및 IGF-1에 미치는 영향을 규명하는 것이다. 본 연구의 대상자는 근감소성 비만을 가지고 있는 노인 여성 20명으로 운동 집단과 통제 집단으로각 10명씩 무선할당 하였다. 운동 집단 대상자는 12주간 주 3회, 회당 60~80분씩 운동 트레이닝을 실시하였고, 통제집단 대상자는 동일한 처치 기간에 평소의 생활습관을 그대로 유지하도록 하였다. 처치 전과 후에 체력, 등속성 근기능과IGF-1을 측정하였고, 이후 두 집단 간, 그리고 두 시기 간을 비교하여 다음과 같은 결과를 얻었다. 첫째, 체격과 신체구성과 관련하여, 체중, BMI, 체지방률그리고 제지방량이 운동 집단에서 유의하게 개선되었다. 둘째, 체력과 관련하여, 악력, 상완굴신력, 의자에앉았다일어서기, 그리고 VO2max가 운동 집단에서 유의하게 증가되었다. 셋째, 등속성 근기능과 관련하여, 신전과 굴곡의 최대힘효율, 총일량, 그리고 평균파워가 운동 집단에서 유의하게 증가되었다. 넷째, IGF-1이 운동집단에서 유의하게 증가되었다. 본 연구결과를 종합해 보면, 12주간 실시한 복합운동 프로그램이 근감소성 비만 노인여성의 신체구성, 체력, 등속성 근기능, 그리고 IGF-1의 개선에 긍정적인 영향을 미치는 것으로 결론지을 수 있다.

본 례는 65세 남자 환자에서 전폐절제술후에 발생한 기관지 늑막루 및 농흉의 치험례로 일차적으로 만성화하게한 다음 정중흉골절개하 심낭절개로 좌 주기관지를 노출후 자동봉합기(TA 4.8-30)로 좌 주기관지를 이중 결찰 봉합하여 좌측 늑막강내의 염증을 일으키는 원인인 기관지 늑막루를 차단한 다음, 늑막강내의 농흉을 치료함에 있어 흉강경을 이용하여 변형된 Clagett술식으로 내면을 깨끗하게 세척한 후 민감한 항생제를 이용하여 늑막강을 채우고 흉강삽관을 뽑고 그 부위를 봉합하는 방법을 시행하여 잔존 농흉강을 폐쇄하였다. A patient with post-pneumonectomy empyema was treated sucessfully by modification of Clagett's operation after closure of bronchopleural fistula using a transsternal, transpericardial approach. His primary disease was pulmonary tuberculosis, and he had a past history of left upper lobe lobectomy 34 year ago. Recently recurred pulmonary tuberculosis with aspergilloma in the remaining left lung, empyema with bronchopleural fistula had developed on the post-operative 4th day after completion pneumonectomy. Closed thoracostomy was done at the lowest point of the left pleural cavity immediately. The pleural cavity was irrigated with small amount of normal saline through pigtail catheter. The 2nd operation was done by closure of bronchopleural fistula using a stapler through transsternal, transpericardial approach, and then the pleural space was irrigated with normal saline with Tobramycin which shows sensitivity to isolated organism from pleural cavity. After negative conversion of pleural fluid culture, we performed modified Clagett's operation under local anesthesia. The patient had no evidence of recurrence of empyema and discharged from hospital after 10 days of the 3rd procedure.

정원상,선예린,박훈영,김성우,정회룡,박신애,김지수,임기원 한국운동영양학회 2023 Physical Activity and Nutrition (Phys Act Nutr) Vol.27 No.1

[Purpose] We compared and analyzed energy consumption and excess post-exercise oxygen consumption (EPOC) following Taekwondo Taegeuk Poomsae performances. [Methods] Forty-two healthy men who could perform Taegeuk Poomsae 1–8 Jangs were enrolled in this study. To reduce the impact of Poomsae, a random cross-design was used. The washout time was set to at least three days. Oxygen consumption (VO2) was monitored after performing each Poomsae until a reference line was resumed. Each Taegeuk Poomsae was performed at a speed of 60 bpm. [Results] There was no significant difference in VO2, carbon dioxide excretion, and heart rate after performing the Taegeuk Poomsae once; however, all variables increased significantly in combined results of EPOC metabolism (F<45.646, p<0.001, and ɳ2<0.527). Taegeuk 8 Jang had the highest levels of all the factors. There were noticeable variations in the oxidation of fat and carbohydrates throughout the Taegeuk Poomsae (F<9.250, p<0.001, ɳ2<0.184). Taegeuk 8 Jang demonstrated the greatest rate of carbohydrate oxidation, and 4–8 Jangs demonstrated much greater rates of fatty acid oxidation. Compared to 1 Jang, the energy consumption showed significant differences in all the variables and peaked in Taegeuk 8 Jang. [Conclusion] The energy consumption during the Poomsae performances was the same. When the EPOC metabolism was coupled, it was evident that more energy was substantially used in each chapter of Poomsae. Consequently, it was determined that when performing Poomsae, not only should energy metabolism during exercise be taken into account but also EPOC metabolism, which can increase by 10-fold.
