  • We previously demonstrated that the methylene chloride fraction of Scutellaria barbata suppessed human leukemic U937 cell proliferation by inducing apoptosis. In the present study, we have isolated luteolin from Scutellaria barbata and evaluated its apoptotic mechanism in Lewis lung carcinoma cells. Luteolin inhibited the proliferation of Lewis lung carcinoma cells in a concentration-dependent manner. Luteolin effectively increased the portion of $sub-G_1$ DNA content (apoptotic portion) and apoptotic Annexin-V positive cells in a concentration-dependent manner by FACS analysis. Caspase 9 and caspase 3 were activated and PARP was effectively cleaved by luteolin. It also increased the ratio of Bax to Bcl-2 through the decrease of Bcl-2 expression by Western blotting and reduced mitochondrial membrane potential following TMRE staining. These results suggest that luteolin can induce apoptosis through the mitochondrial mediated pathway.

생쥐의 B 세포에서 면역글로블린 E의 분비와 사이토카인 생산에 대한 가미육군자탕의 효과 (Effects of Kamiyukgunja-tang on anti-CD40 and Recombinant Interleukin-4 induced Cytokine Production and Immunoglobulin E in Highly Purified Mouse B Cells)

  • In order to evaluate the antiallergic effects of Kamiyukgunja-tang (KYGJT), studies were done. We measured the cytotoxic activity for lung fibroblast cell, cytokines transcript expression, production of INF-γ, IL-10, IL-4, GM-CSF, IL-1 β, TNF-α. IL-5 proliferation of B cell in anti-CD40mAb plus r1L-4 stimulated murine splenic B cells. The results were obtained as follows : 1. KYGJT was not showed cytotoxicity in the fibroblast lung cell. 2. KYGJT increased the gene synthesis of INF-γ, IL-10, GM-CSF(m-RNA). 3. KYGJT decreased the gene synthesis of IL-1β, IL-4, TNF-α, IL-5(m-RNA). 4. KYGJT decreased the appearance of TNF-α significantly. 5. KYGJT decreased the appearance of IgE significantly. 6. KYGJT decreased the proliferation of B cell significantly. 7. KYGJT decreased the appearance of Histamin Release Production significantly. The facts above prove that KYGJT is effective against the allergy. Thus. I think that we should study on this continuously

  • Magnetic Resonance Imaging (MRI) is one of the most advanced imaging techniques in clinical and research medicine. However, clinical application of MRI to the lung or thorax has been limited due to various drawbacks. Low signal intensity of the lung and cardiac and respiratory movements are the most serious problems with MRI in thorax. Nevertheless, MRI is superior to CT in some selected patients with thoracic diseases. The role of clinical MRI in thoracic disease has been widened with improvement of MR equipments and development of new pulse sequences. Otherwise, functional assessment of lung by MRI has been studied for the last decade. These include perfusion MRI with or without contrast enhancement and ventilation MRI with oxygen-enhancement or hyperpolarized noble gas, $^3He$ and $^{129}Xe$.

  • Pulmonary blastoma is rare malignant neoplasm usually situated peripherally in lung and composed of epithelial and mesenchymal components that resemble the lung at about 3 months gestation. Fortysix year-old man had no symptoms and signs, but solitary pulmonary nodule was found accidentally in a routine simple chest X-ray occupying right upper lung field. Preoperative chest CT-guided aspiration cytology revealed adenocarcinoma. We had done right upper lobectomy with Iymph node dissecton therapeutically. Final postoperative pathology reported this tumor as double pulmonary blastomas(well differentiated fetal adenocarcinoma). We report a case of pulmonary blastoma with review of literature.

  • Primary pulmonary lymphoepithelioma-like carcinoma (LELC) is rare, with a more favorable prognosis compared with that of other types of non-small cell lung cancers. Herein, we describe an interesting case of primary pulmonary LELC confirmed postoperatively, which had been initially diagnosed as poorly differentiated adenocarcinoma. We suggest that despite the rarity of pulmonary LELC, it should be included as one of the differential diagnoses for lung malignancies. Physicians should consider taking a larger biopsy, especially when histologic examination shows undifferentiated nature.

  • Diagnostic procedures in pregnant wowen is limited and is usually delayed, especially so if she is on mechanical ventilation. A 28-year-old pregnant woman with severe dyspnea was referred to our hospital under the impression of miliary tuberculosis. The respiratory failure was so severe that patient had to be managed with mechanical ventilator under clinical impression of overwhelming pneumonia or pulmonary tuberculosis. But the patient's conditions deteriorated. Bronchoscopy and blind transbronchial lung biopsy performed to determine the nature of the etiology, and to our surprise, revealed squamous cell carcinoma of the lung.

  • Primitive neuroectodermal tumor (PNET) arising primarily in the lung is an extremely rare and aggressive malignancy with poor chances of patient survival. We present a case of long-term survival by a 29-year-old woman with PNET diagnosed after a hertological and immunohertochemical examination of a biopsy specimen obtained by performing video-assisted thoracic surgery. The patient underwent a left lower lung lobe lobectomy and 6 cycles of adjuvant chemotherapy. The patient has been free of any symptoms of the recurrence of the disease for 6 years after treatment completion.

  • A 71-year-old male patient visited Yeungnam University Hospital with abnormal chest computed tomography (CT) findings. Chest CT revealed multiple lung nodules and a posterior mediastinal tumor, the diagnosis of which was confirmed surgically. Magnetic resonance imaging (MRI) of the abdomen showed multiple small nodules, which were diagnosed as cavernous hemangioma in the liver based on the pathology results of the mediastinal and lung masses in combination with MRI findings. Cavernous hemangiomas are benign tumors that can occur throughout the body, mainly in the skin and subcutaneous tissue. The liver is the most common internal organ containing hemangiomas, whereas they are very rarely found in the lungs or mediastinum.
