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.

Background: Lung transplantation is a definitive therapy for a variety of end stage lung diseases. Since 1996, we have performed thirteen cases of lung transplantation including two retransplantations, and we analyzed the outcomes, complications, and survivals of these patients. Material and Method: We retrospectively analyzed the medical records of thirteen cases from July, 1996 to July, 2005. Result: During the period, 11 patients had undergone 43 lung and heart-lung transplantations, and two patients had retransplantation due to allograft failure. Mean age of recipients were $45.2{\pm}10.7$ years(range, $25{\sim}59$). Early complications were bleeding, reperfusion injury, and infection and late complications were mainly infection and post-transplantation lymphoproliferative disease. Excluding the operative mortality, the mean survival period was 16.5 months($2{\sim}60$ months). Two retransplantations had been performed 2 weeks and 13 months after single lung transplantations. Conclusion: In order to achieve long term survival, early detection of complications and proper treatment in addition to surgical skills are necessary, and these efforts can promote better lung transplantation programs in the near future.

A retrospective analysis was performed or 102 patients with non-small cell lung cancer who received the curative radiotherapy from August 1985 to October 1988 at the Department of Therapeutic Radiology of Chonnam University Hospital. The follow-up period was ranged from 1 to 37 months and the median follow-up time was 15 months. The acturial 1 and 2 year survival rate of all the patients was $28\%\;and\;5\%$, respectively. The median survival was 10 months for stage II, 6 months for stage IIIA, and 9 for IIIB and the actuarial 2 year survival tate was $12.5\%,\;12.1\%,\;and\;0\%$ respectively. The treatment failure was identified in 32 patients and the locoregional failure was seen in 9 patients ($28\%$) and the distant failure in 23 patients ($72\%$). The initial performance status was related to the survival with statistical significance (p<0.01), but the survival difference by the radiation dose was not statistically significant (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.

Congenital pulmonary vein stenosis is a rare anomaly and related to high mortality due to progressive pulmonary hypertension and heart failure in infancy. Aggressive anti-failure medication and surgical treatment is recommended. Surgical options are balloon dilatation, endovascular stent, pneumonectomy, lung transplantation, patch grafting, and sutureless repair. We report a case of congenital pulmonary vein stenosis with normal anatomical connection successfully treated with sutureless technique and using pulmonary vasodilators, such as Sildenafil, lloprost and iNO postoperatively.
