  • Pulmonary systemic arterialization to normal basal lung without sequestration is a rare congenital anomaly. In this rare abnormality, arterialization of the left lower lobe is the most common type. In general, surgical treatments have been performed. Recently, for reducing the complications and risks of surgery, embolization is mainly attempted by using coils. We report a case of 22-year-old male patient with a 10 mm anomalous arterial supply to his normal lung, which is being successfully treated by transcatheter embolization when using the Amplatzer Vascular Plug that has been adapted for the treatment of high-flows and large artery occlusions.

  • A 7-year-old intact female Maltese dog presented with a history of bite wounds. Physical examination revealed labored breathing, four puncture wounds with subcutaneous emphysema of the thorax, and paradoxical respiratory movement of the right thoracic wall. On radiography, a segmental fracture of the right 7th rib and a single fracture of the 8th rib were evident on the dorsal thorax. An inward displacement of the fractured segment and contusion of the right caudal lung lobe were identified with computed tomography. A diagnosis of pseudo-flail chest was made. Exploratory thoracotomy revealed a full-thickness muscular defect, a marked discoloration of the right caudal lung lobe, a segmental fracture of the right 7th rib, and a single fracture of the right 8th rib. Necrotic tissues were removed using surgical debridement. The fractured 7th and 8th ribs were corrected using a single interfragmentary wiring technique. The thoracic wall was reconstructed using the latissimus dorsi muscle flap. Additional thoracic stabilization using a thermoplastic splint was applied to correct paradoxical respiratory movement. The external splint was removed 4 weeks postoperatively. There was no evidence of respiratory abnormalities 18 months postoperatively.

  • Pneumoconiosis is one of the major problem in the field of occupational health at Korea. Therefore, the efficient diagnosis of pneumoconiosis is a hot issue on the occupational health program. The author executed this study to estimate the diagnostic value of high resolution computed tomography(HRCT) compared with chest radiography for screening of welder's lung. HRCT was introduced very recently for the diagnosis of pneumoconiosis, however, the diagnostic value for screening of welder's lung - principally nonfibrogenic and reversible - has not been evaluated. The subjects were fifty cases of welder's lung or suspected cases who had been collected between 1989 and 1994 from one shipyard and continuously followed-up on the basis of in-plant periodic health check program. We applied both chest radiography and HRCT on the same subjects from May 1 to 30, 1996. The images were evaluated by two careered radiologists independently. The findings of chest radiography were classified into four category by ILO classification, and the findings of HRCT according to the criteria of Bergin et al. The concordance between two radiologists expressed with Kendall's tau-b was 0.72 by chest radiography and 0.44 by HRCT- that is, interobserver variation of HRCT was bigger than that of chest radiography. The concordance between the two different methods was highly variable as 0.44 by radiologist A and 0.06 by radiologist B - that is, interobserver variation was very big. However, HRCT looked more detectable for the minor parenchymal change. These findings suggested that it is not appropriate to use HRCT routinely for screening of welder's lung due to lack of diagnostic criteria, and feasibility, acceptability and economic aspects. Nevertheless, HRCT might be recommendable in the case of equivocal parenchymal features on the chest radiography, unexplained respiratory symptoms, and/or lung function abnormalities suggestive of interstitial fibrosis.

  • An experimental comparative study was done to determine the protective effects of three preservation solutions on isolated rabbit heart-lung bloc during acute ischemia and reperfusion of the lung during lung transplantation. Thirty Isolated rabbit heart-lung blocs were divided into 3 groups , group I(n:9) was preserved with Hartmann's solution, group II(n: 10) with modified University of Wisconsin solution, and group III(n: 1 1) with Kosin solution. The isolated heart-lung blocs were washed with Hartmann's so ution. Aftar infusion of each preservation solution into pulmonary artery, the heart-lung bloc was stored at 4'c cold preservation solution for each group for 4 hours and .then the heart-lung blocs were reventilated and reperfused. The changes of weight of heart-lung blocs, airway pressure, percent change of PCO2, level of lactate and adenosine deaminase(ADA) and microscopic structure of the lung parenchyme were evaluated. Results were as follows 1. A change of weight of the heart lung bloc after reperfusion was lowest in group 111(p< .05) 2. The airway pressure increased after reperfusion in group I but decreased in group II, and II. Especially in group II, post-reperfusion airway pressure returned to level lower than that of en-bloc resection. 3. Pulmonary artery pressure during reperfusion after 4 hour preservation was lowest in group III, and pulmonary artery pressure in group II was higher than in group I(P> 0.1). 4. The level of lactate and ADA in the lung tissue were higher in group III than in group I and II(P< .05) 5. The percent change of PCO2 in perfusate was slightly higher in group III than group I and II. 6. Microscopic changes in lung tissue after reperfusion were diffuse pulmonary edema, expansion of inter- stitial tissue, focal aggregation of erythrocytes, and basement membrane abnormalities, but no differences were found among the three groups. In conclusion, the protective effects of modified University of Wisconsin solution and Kosin solution were slightly superior to Hartmann's solution.

  • A 68-year-old man with Guillain-Barre syndrome after the resection of right upper lobe for squamous cell lung cancer is presented. He developed a sudden, symmetric, extremity weakness, respiratory insufficiency, and sensory ataxia on postoperative day 6. He was intubated emergently and placed on a ventilator. Electrodiagnostic studies were performed on days 2, 20, and 40 following the onset of weakness. Motor nerve conduction abnormalities were the predominant findings. Prolonged motor distal latencies, temporal dispersion, and partial motor conduction blocks were present and formed the diagnostic features of Guillain-Barre syndrome. With supportive care and additive use of intravenous immunoglobulin, the illness resolved 6 weeks later after the onset of weakness.

  • Intralobar pulmonary sequestration is a rare congenital lung anomaly. It is defined as a portion of nonfunctioning lung parenchyma that receives its blood supply from an anomalous systemic artery. Patients often present with chronic or recurrent pneumonia. A chest radiograph may show a cystic lesion with air-fluid levels in the lung base. A high index of suspicion is needed for a diagnosis. Surgical removal of a symptomatic intralobar pulmonary sequestration is generally the treatment of choice. Identifying the aberrant artery is a difficult problem when resecting a pulmonary sequestration. The thoracic and abdominal aortas are the most common origins for the abnormal blood supply. However, arterial supply from the celiac artery is quite rare. We present a case of intralobar pulmonary sequestration with the blood supply originating from the celiac artery.

  • A 7-year-old female, Jindo dog was referred to the Veterinary Teaching Hospital with mild dyspnea and anorexia due to a gunshot trauma. The dog was wounded in the thoracic region 3 days ago. Plain radiographs showed the left 8th rib fracture, interstitial pattern in the left caudal lung field and pleural effusion. Abdominal radiographs showed the lead bullet. Computed tomographs(CT) showed the size of pulmonary contusion, laceration, lung parenchymal injuries, hemothorax and perforation of abdominal wall. The therapeutic plan was based on abnormalities seen on CT scans but not clearly seen in survey radiographs. Thoracic CT significantly provides even more informations compared with the corresponding radiographs in thoracic gunshot trauma. Although thoracic survey radiographs are useful as a screening tool, CT is highly sensitive in detecting thoracic injuries after thoracic trauma and is superior to routine thoracic survey radiographs in visualizing lung contusion, pneumothorax and hemothorax. Therefore, we recommend CT in the initial diagnostic work-up of patients with thoracic injuries and with suspected chest trauma because early and exact diagnosis of all thoracic injuries along with sufficient therapeutic consequences may reduce complications.

  • Objectives: Sweet bee venom (sBV) is purified from Apis mellifera, containing a high level of melittin-its main component. It has been used as a therapeutic agent for pain relief and anti-inflammation, as well as for treating neuronal abnormalities. Recently, there have been studies on the therapeutic application of sBV for anticancer treatment. In the present study, we investigated the pharmacological effect of sBV treatment in A549 human lung cancer cells. Methods: We used microscopic analysis to observe the morphological changes in A549 cells after sBV treatment. The MTT assay was used to examine the cytotoxic effect after dose-dependent sBV treatment. Molecular changes in sBV were evaluated by the expression of apoptosis marker proteins using western blot analysis. Results: Microscopic analysis suggested that the growth inhibitory effect occurred in a dose-dependent manner; however, cell lysis occurred at a concentration over 20 ㎍/mL of sBV. The MTT assay indicated that sBV treatment exhibited a growth inhibitory effect at a concentration over 5 ㎍/mL. On fluorescence activated cell sorting analysis, G0 dead cells were observed after G1 arrest at treatment concentrations up to 10 ㎍/mL. However, rapid cell rupture was observed at a concentration of 20 ㎍/mL. Western blot analysis demonstrated that sBV treatment modulated the expression of multiple cell death-related proteins, including cleaved-PARP, cleaved-caspase 9, p53, Bcl2, and Bax. Conclusion: sBV induced cell death in A549 human lung cancer cells at a pharmacological concentration, albeit causing hemolytic cell death at a high concentration.

  • Infantile lobar emphysema is a pulmonary hyperinflation state that has the clinical features of an air block syndrome characterized by bronchial cartilaginous abnormalities or unknown origin. Left upper lobe was affected in most of the reported infantile lobar emphysema. Infantile lobar emphyema is divided into two categories. e.g., congenital and acquired. We have experienced a case of left lower lobe involved infantile lobar emphysema which had undergone left pneumonectomy. She had progressive signs of tension accompanied by mediastinal displacement, ventilatory and circulatory failure in infant period. Because of the combined left upper lobe hypoplasia, left pneumonectomy was performed. And there was no cartiliginous abnormality in pathologic finding. This is the first domestic case which was affected in the lower lobe and successful surgical repaired.

  • Fourteen cases of funnel deformity, 11 were male and the others female, treated over a eleven-year period, are presented. The overall results with the methods described by the authors, Wada, Shannon, Adkins and Ravitch appear to be excellent. The symmetric depression was more common In children under the age of 12 years and asymmetric one Increased after the age of 12. Six cases of abnormal cardiac auscultatory findings revealed no consistent hemodynamic abnormalities. An 21-year-old female was associated with left lung agenesis and dextroversion of the heart, and a 6-year-old boy with congenital bronchogenic cyst who underwent right upper lobectomy. EKG changes associated with the anomaly were observed in all. Pulmonary function test showed the range from normal to moderate restriction which did not Improve in only one patient after operation, but the patient did not complain any restriction In activity. Some transient complications were developed which resulted in improvement.
