  • In many conventional drug delivery systems in vogue, failure to deliver efficient drug delivery at the target site/organs; is evident as a result, less efficacious pharmacological response is elicited. Microspheres can be derived a remedial measure which can improve site-specific drug delivery to a considerable extent. As an application, Lung-targeting Ofloxacin-loaded gelatin microspheres (GLOME) were prepared by water in oil emulsion method. The Central Composite Design (CCD) was used to optimize the process of preparation, the appearance and size distribution were examined by scanning electron microscopy, the aspects such as in vitro release characteristics, stability, drug loading, loading efficiency, pharmacokinetics and tissue distribution in albino mice were studied. The experimental results showed that the microspheres in the range of $0.32-22\;{\mu}m$. The drug loading and loading efficiency were 61.05 and 91.55% respectively. The in vitro release profile of the microspheres matched the korsmeyer’s peppas release pattern, and release at 1h was 42%, while for the original drug, ofloxacin under the same conditions 90.02% released in the first half an hour. After i.v. administration (15 min), the drug concentration of microspheres group in lung in albino mice was $1048\;{\mu}g/g$, while that of controlled group was $6.77\;{\mu}g/g$. GLOME found to release the drug to a maximum extent in the target tissue, lungs.

  • We report a case of delayed chest wall reconstruction after thoracotomy. A 53-yearold female, a victim of a motor vehicle accident, presented with bilateral multiple rib fractures with flail motion and multiple extrathoracic injuries. Whole-body computed tomography revealed multiple fractures of the bilateral ribs, clavicle, and scapula, and bilateral hemopneumothorax with severe lung contusions. Active hemorrhage was also found in the anterior pelvis, which was treated by angioembolization. The patient was transferred to the surgical intensive care unit for follow-up. We planned to perform surgical stabilization of rib fractures (SSRF) because her lung condition did not seem favorable for general anesthesia. Within a few hours, however, massive hemorrhage (presumably due to coagulopathy) drained through the thoracic drainage catheter. We performed an exploratory thoracotomy in the operating room. We initially planned to perform exploratory thoracotomy and "on the way out" SSRF. In the operating room, the hemorrhage was controlled; however, her condition deteriorated and SSRF could not be completed. SSRF was completed after about a month owing to other medical conditions, and the patient was weaned successfully.

  • Acute eosinophilic pneumonia is a severe and rapidly progressive lung disease that can cause fatal respiratory failure. Since this disease exhibits totally different clinical features to other eosinophilic lung diseases (ELD), it is not difficult to distinguish it among other ELDs. However, this can be similar to other diseases causing acute respiratory distress syndrome or severe community-acquired pneumonia, so the diagnosis can be delayed. The cause of this disease in the majority of patients is unknown, even though some cases may be caused by smoke, other patients inhaled dust or drugs. The diagnosis is established by bronchoalveolar lavage. Treatment with corticosteroids shows a rapid and dramatic positive response without recurrence.

  • We experienced a series of animal experimental studies of the total artificial heart in 1988. So called, "Korean Heart* was used in this study, which is developed and fabricated in the Department of Biomedical Engineering, College of Med., S.N.U.. "Korean Heart" is a Rolling-Cylinder Motor-Driven type which is a newly developed electromechanical heart over the shortcomes of the previous artificial hearts, especially pneumatic type. The advantages of the "Korean Heart" are total implantability, quiet and smooth movement, small size fittable in oriental people, etc. The animal experiments were performed two times, as an assist device in sheep and total artificial heart implant experiment in calf weighing 100 kg. After total implantation, the artificial heart was well functioned in movement and hemodynamic control. So that, the calf was recovered excellently, which was able to stand up by herself and take an oral intake. Total survival time was 100 hours and the cause of death was a sudden pumping failure [electrical connection problem]. Several postoperative laboratory results almost within normal limits and no hemolysis, but in autopsy, the multiple thromboembolic findings were seen at the lung and kidney.n at the lung and kidney.

  • 배경: 폐 이식 수술은 호흡부전을 동반한 말기 폐질환 환자에서 유용한 치료방법 중의 하나로 본원에서는 1996년 국내에서 처음으로 일측 폐 이식 수술을 성공한 이래로 현재까지 재 이식 2예를 포함한 총 13예의 폐 이식 수술을 시행하였다. 저자 등은 그동안 환자들의 수술성적 및 합병증, 생존율 등을 분석하고자 하였다. 대상 및 방법: 1996년 7월부터 2005년 7월까지 영동세브란스병원 흉부외과에서 폐 이식을 시행받은 13예, 11명의 환자(2명은 재 이식환자)를 대상으로 후향적으로 임상기록지를 분석하였다. 결과: 남녀비는 9:4, 평균연령은 $45.2{\pm}10.7$세(범위 $25{\sim}59$세)였으며, 폐기종 및 만성폐쇄성 폐질환이 5예로 가장 많았고, 동맥관 개존증으로 인한 아이젠맹거 증후군 2예, 폐섬유증, 폐고혈압, 림프관 평활근종증, 기관지확장증이 각 1예였다. 조기 합병증으로는 출혈, 이식 폐 부전, 감염이며 후기 합병증으로는 감염 및 이식 후 림프증식증이었다. 조기사망 3예를 제외한 평균생존기간은 16.5개월($2{\sim}60$개월)이었다. 재 이식 2예는 이식 폐의 기능 부전에 의하여 각각 첫 이식 후에 2주, 13개월째 시행 받았다. 결론: 폐 이식 수술 후 장기성적을 향상시키기 위해서는 수술술기의 향상뿐만 아니라 수술 후 집중적인 환자관리를 통하여 합병증을 조기에 발견하고 필요한 내과적, 외과적 처치를 즉시 시행하는 것이 예후에 좋은 영향을 미칠 것으로 생각된다.

  • 1985년 8월부터 1988년 10월까지 전남대학교병원 치료방사선과에서 근치목적의 방사선치료를 받은 비소세포성 폐암환자 102명에 대하여 후향적 분석을 시행하였다. 대상환자들에 대한 추적조사기간은 1개월에서 37개월이었고 중간값은 15개월이었다. 전체환자군의 1년 및 2년 생존율은 각각 $28\%,\;5\%$였으며 임상적 병기별로 보면 II, IIIA, IIIB기 환자군의 평균생존기간은 각각 10개월, 6개월, 9개월이었고 2년 생존율은 각각 $12.5\%,\;12.5\%,\;12.1\%,\;0\%$였다. 방사선치료후 치료실패가 확인된 32명에 대하여 분석을 하여보면 국소실패군이 $28\%$(9명)였으며 원격실패군이 $72\%$ (23명)로 폐암환자의 사망의 대부분은 전신적인 원격전이에 의함을 알 수 있었다. 치료당시의 전신적 건강상태를 생존율에 유의한 영향을 주었으나(p<0.01), 방사선 치료선량에 따른 생존율의 유의한 차이는 보이지 않았다(p>0.05).

  • According to the research, the Estern and Western medical literatural records about the causes and symptoms of the heart failure, the results as follows are concluded. 1. The asthma, suceptibility to fright and severe palpitation are generally revealed from the left heart failure. The causes of it are belong to the Yang and Yeum deficiency which are mainly caused by primordial energy deficiency. 2. The symtoms of asthma which are derived from left heart failure are related to the gasping that contain dyspnea, asthma due to the accumulation of phlegm and severe palpitation and related to shortness of breath due to fluid retention (水喘) that make asthma. 3. In the right heart failure, the edema which is derived from the congestion of vein, is revealed as stoppage of main channel that is mainly caused by the Yang or the Yeum deficiency. 4. The edema which is caused by the right heart failure, is mainly related to the symptoms of Yeum type edema, also it is related to the five viscera-fluid, moreover to the heart-fluid (心水), lung-fluid (肺水) and liver-fluid (肝水). 5. In heart failure, the pathologic symptoms which are derived from the stoppage of blood circulation, are phlegm-retention disease (痰飮), diffuse fluid-retention syndrom (溢飮), fluid-retention syndrome characterized by dyspnea and edema (支飮).

  • A 3-year-old female jaguar (Panthera onca onca) died after having 1 day history of respiratory failure. At necropsy, the pericardial sac contained large amounts of cloudy fluid enriched with fibrin. Numerous yellowish nodules, which are variable in size and often confluent, are randomly scattered throughout the myocardium. Pasteurella haemolytica was isolated from the pericardial sac and myocardium. In the lung, severe pulmonary congestion, edema and vasculities with intralesional presence of heartworm were found. Therefore the cause of death in this jaguar is believed to be due to respiratory failure following concurrent heartworm infection and bacterial pericarditis and myocarditis.

  • Pulmonary thromboembolism originated most commonly from the venous thrombus, especially deep vein thrombus in the leg, which migrated to and occluded the pulmonary vasculatures. The failure of clot lysis and repeated embolic episodes resulted in the hemodynamic compromise -that is- in the increasing in the pulmonary vascular resistance, which would cause the right ventricle failure[Car Pulmonale]. Under the cardiopulmonary bypass, 20 year old male patient was treated successfully by thromboembolectomy of pulmonary thromboembolism with pulmonary hypertension, which originated from the deep vein thrombus in the leg. The results of radiologic studies and clinical evaluations were excellent in that the postoperative lung perfusion scan showed the newly increased perfusion of post-embolectomy territories and in the arterial blood gas finding of 76 from 66[mmHg] in PaO2. The patient was uneventful and discharged on postop. $ 14 days with anticoagulant continued.
