Pulmonary carcinosarcoma(Sarcomatoid carcinoma of the lung) is a rare pulmonary malignancy, which is defined as having an admixtture of both carcinomatous and sarcomatous components. Pulmonary carcinosarcoma occurs most frequentlly in males between 50 and 80 years of age. It predominantly affects the upper lobe and/or the principal bronchi, and is associated with a history of smoking. Here, we report a case of pulmonary carcinosarcoma with a left lobe atelectasis due to an endobronchial mass in a 56-year-old male. After a left pneumonectomy, the pathologic stage was IIb (T3N0M0). Four months later, an abdominal mass was observed and exploratory laparotomy revealed metastases of the pulmonary carcinosarcoma to the pelvic cavity.

A 61-year-old woman, who had been treated by acupuncture on the glabellar region due to frontal headache ten days ago, had a rapidly growing tumor on that region. Histopathologically, the tumor was shown to be a central crater filled with eosinophilic keratin & a marginal but-tress formed by invagination of the epidermis. According to clinical & histopatholpgical findings, we can easily diagnose our case as solitary keratoacanthoma. As shown in our case, we think that acupuncture should be counted as one of the causative factors in the development of solitary keratoacanthoma.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

Photodynamic therapy(PDT) is a treatment modality by highly reactive oxygen intermediates generated through the interaction of light with a photosensiziter. It has been shown to be an effective treatment for various cutaneous and noncutaneous malignancies. It is efficient for the curative and palliative treatment of epithelial skin tumor in situ or early invasive lesions. In effect, it is a useful alternative treatment for the lesions located on anatomically difficult areas or the large-sized lesions. We treated a case of Bowen's disease arising on the plantar area and 3rd and 4th toewebs of left forefoot in a 61-year-old man with PDT using the hematoporphyrin derivative, porfirmer sodium(Photofrin, Russia) as a photosensitizer and gold vapor laser as a visible light source. The outcome showed partial clinical improvement after about 2 months' follow-up.

OBJECTIVES: The purpose of this study was to evaluate the self-achievement, perception and satisfaction of group discussion and presentation in medical philosophy class. METHODS: A questionnaire was developed based on topical subject of main textbook of medical philosophy and course evaluation reported by students. The questionnaire composed of self-learning achievement for the seven subjects, perception of necessity and profitability of contents and education method of medical philosophy and satisfaction with components of education method and overall class. RESULTS: The data were collected from 250 medical students who complete the course of medical philosophy. Regardless of grade and gender, students reported high self-achievement, perception and overall satisfaction of medical philosophy course, but there were difference in satisfaction of components of each education methods. Students recognized positively as discussion and presentation in philosophy class, but had low awareness of the benefits of private small-group activities. The more students regarded it is beneficial for the contents and methods of philosophy classes, the overall satisfaction with the medical philosophy course was high. And the more students regarded it is necessary to educate and beneficial for the contents and methods of philosophy classes, the satisfaction with the education methods of medical philosophy course was high. CONCLUSION: To improve the achievement level and satisfaction with the philosophy course, it is necessary to induce active interest in small group activities, and provide detailed and various discussion materials in class.

Antibiotics were reported to be able to alter bacterial surface properties in subinhibitory concentrations (sub-MICs). The effects of sub-MICs of certain antibiotics on a bacterial surface property such as hemagglutination, as well as on the cell morphology were studied using Streptococcus gordonii and Staphylococcus aureus. The effect of sub-M1Cs of antibiotics on the binding of these bacteria to immobilized fibrinogen were also investigated. The MICs of antibiotics were determined by culturing S. gordonii and S. aureus in media supplemented with serially diluted drug solutions, and one-half the MIC was used as the sub-MIC of the drugs, unless stated otherwise. Sub-MICs of antibiotics did not affect bacterial agglutination of erythrocytes. Microscopic observation of S. gordonii grown at sub-MIC concentration of 0.02 ug/ml of amoxicillin revealed cell enlargement of 1.6 times those grown without the drug. When grown in the sub-MIC amount of 0.08 ug/ml of cefazolin, most S. gordonii cells were enlarged and elongated into rod-shape, resulting in 3 times the size of the cells grown without the antibiotic. The data from the fibrinogen-binding experiments showed that the binding of S. gordonii to immobilized fibrinogen was increased with all the B-lactam drugs tested; the binding of S. aureus to immobilized fibrinogen, on the other hand, was decreased with the same drugs. The results show that low concentrations of certain B-lactam antibiotics are able to cause alterations in cellular morphology of S. gordonii and affect the binding of S. gordonii and S. aureus to immobilized fibrinogen.
