BACKGROUND: It goes without saying for the importance of pre-hospital care in EMS system. At present 119 rescuers take charge of the majority for the pre-hospital care in Korea. But the present activity and job satisfaction of 119 rescuers is not studied. METHOD: The authors analyzed the questionnaire from the 98 rescuers had taken the lessons on emergency medical technician training program at the Central Fire Fighting School, Cheonan city. We used a Likert's five stage barometer for the analysis of job satisfaction. RESULTS: On regional distribution of rescuers 29.6% was in metropolitan city and 70.4% was from each province. On sexual distribution male was 93%, average age was about 30 years old. The academic background was commonly below the high school graduation. Sixty-one of 98 rescuers (62.2%) was married. The monthly mean income is 1.07 million Won. There was a statistical difference of the monthly mean income between the age, sex, and the period of work (p<0.05). The average duration of job was 27 months. In most cases. the patients or relatives decided the evacuation hospital (89.8%). 67.0% of rescuers answered the necessity of emergency communication system during transport. The serious problems during transport were the lack of manpower, the knowledge of emergency care, the deficit of emergency equipment and telecommunication system. The priority of decision for evacuation hospital is the presence of special medical team, the severity of patients, the presence of modern hospital. The emergency equipment of ambulance was satisfactory in general. Almost all the rescuers (99.0%) want continuous education and 92.7% of them want at the emergency center or general hospital twice a year. The degree of job satisfaction was the job of special knowledge and skills, the professional work and self-assurance in order. CONCLUSION: 119 rescuers were gratified generally at the job satisfaction. But it was poor at work condition. The authors think that a government office and the korean society of Emergency Medicine must hard work for the improvement of work condition and the administration of continuous education.

We present a case of mucous gland adenoma arising from the main bronchus of the lower lobe of the left lung in terms of clinicopathologic, immunohistochemical, and ultrastructural aspects as well as review of related literatures. The patient, a 31-year-old female, was admitted to Catholic University Medical College Hospital with complaints of coughing and purulent sputum for about seven years. The chest CT showed a severely calcified tumor in the left lower lobe of the lung. Grossly, the calcified tumor arising from the main bronchus protruded into the lumen and showed bronchiectasis of the lower lobe and atelectasis of the upper lobe of the lung. The tumor was pale brown-gray and sharply circumscribed and showed some small cystic spaces filled with mucoid material. Microscopically, most of the tumor showed dystrophic calcification. The growth pattern of the tumor is composed of cysts, tubules, and glands lined by cytologically bland columnar, cuboidal, or flattened mucus secreting cells. Electron micrograph of tumor cells showed some round or oval mucous granules measuring 0.5-1.8 micrometer.

CONCLUSION: The Taping therapy intervention proved effect pain relief and depression decrease as well as promote of range of motion.

Sarcomatoid carcinomas are malignant epithelial neoplasms in which the tumor cells assume a partial or complete spindle cell pattern of growth, leading to the erroneous classification of some true carcinomas as sarcomas. These spindle cells are malignant and manifest various amount of both vimentin and cytokeratin. Positive reaction of some of the spindle cells for cytokeratin antibodies is confirmatory. Clinical features do not differ significantly from those of patients with high-grade transitional cell carcinoma. So far, 13 cases of sarcomatoid transitional cell carcinoma of the renal pelvis have been reported in English and Korean literature. In this report, we describe clinicopathologic features of recently observed two cases of sarcomatoid transitional cell carcinoma of the renal pelvis and summarize the pathologic findings of previously reported cases with review of the literature.

OBJECTIVE: Recently, the incidence of elderly primipara is increasing. Thus, impact of old age on pregnancy outcomes became important. Our purpose was to assess the effect of maternal age on pregnancy outcomes. METHODS: 73 cases of the elderly primipara over 35 years at the department of obstetrics and gynecology, Chon-ju presbyterian medical center, from Jan. 1, 1995 to Dec. 31, 1998, were compared with 73 cases randomly chosen young primiparas during same period. RESULTS: Elderly primipara had higher rate of infertility and spontaneous abortion history, antenatal complications, cesarean section, poorer neonatal outcome than young primipara. CONCLUSION: The pregnancy outcome of elderly primipara is considered to be less favorable than those of young primipara. Careful antenatal and intrapartal care should be performed for the elderly primipara. We think that many clinical study of congenital anomaly in elderly primipara will be necessary.

Primary pulmonary Hodgkin's lymphoma is a rare but distinct entity to be distinguished from nodal Hodgkin's lymphoma and from lymphomas involving lung secondarily. This lymphoma affects women more frequently than men, and typically involves superior portions of the lung. This case is reported to illustrate the clinical, radiographic and anatomic characteristics of the primary pulmonary Hodgkin's lymphoma. A 34-year-old woman presented for the evaluation of hemoptysis. A chest CT revealed a large poorly defined mass in the medial aspect of the right upper lobe, extending to the right mediastinum and trachea. The microscopic examination of the biopsied lesion revealed fibroblastic stroma infiltrated by a mixture of lymphocytes, histiocytes, and eosinophils. The clinical impression was inflammatory pseudotumor, presumably due to slightly favorable response to corticosteroid therapy. Two months later the patient's symptoms worsened despite the steroid therapy and a lobectomy was done. The specimen showed a soft to firm, pale yellow, ill defined mass, 10.0 8.0 cm, involving the visceral pleura. A few satellite nodules around the main mass were noted. The histologic findings were consistent with Hodgkin's lymphoma, nodular sclerosis type.

To elucidate the role of p53 and nm23 in the development, progression, and metastasis of non-small cell lung cancer, we studied 91 paraffin sections of the primary non-small-cell lung cancers and the 34 paraffin sections of their metastatic lymph nodes using the immunohistochemical method. The results are as follows: 1) The incidence of p53 protein expression was positively correlated with the staging of lung cancers (p<0.025). 2) The incidence of p53 protein expression was higher in the lung cancers with lymph node metastasis than in those without lymph node metastasis (p=0.009). 3) The incidence of nm23 protein expression was lower in the adenocacinomas than in the squamous cell carcinomas (p=0.032). 4) The incidence of nm23 protein expression was lower in the lung cancers with lymph node metastasis than in those without lymph node metastasis (p=0.026). The expression of nm23 protein between the primary lung cancers and corresponding metastatic lymph nodes showed positive correlation (Kendall's Tau-b correlation coefficient=0.47140, p=0.0068). 5) The expression of p53 was not correlated with the expression of nm23 protein (Kendall's Tau-b correlation coefficient=0.11387, p=0.2800). The above results suggest that an overexpression of p53 protein and a downregulation of nm23 protein are associated with tumor progression and metastasis in non-small-cell lung cancer.

A smooth muscle hamartoma is a benign proliferation of smooth muscle bundles within the dermis. It arises from smooth muscle cells that are located in arrector pili muscles, dartos muscles, vascular smooth muscles, muscularis mammillae and the areolae. Acquired smooth muscle hamartoma (ASMH) is rare, with only 10 such cases having been reported in the English medical literature to date. Most of these cases of ASMH were shown to have originated from arrector pili and dartos muscles. Only one case was reported to have originated from vascular smooth muscle cells. A 21 year-old woman presented with a tender pigmented nodule, with numbness, on the sole of her foot, and this lesion had developed over the previous 18 months. The lesion showed no hyperpigmentation or hypertrichosis, and the biopsies demonstrated increased smooth muscle bundles in the dermis, and especially around the blood vessels. Moreover, the specimens stained positive with Masson trichrome stain and alpha-smooth-muscle actin antibodies, thus supporting our diagnosis of ASMH of the foot sole. Herein, we report on a rare case of ASMH on the foot sole, and this lesion originated from vascular smooth muscle cells. This type of case has not been previously described in the English medical literature.

urpose: Misonidazole is a radiosensitizer that binds in hypoxic cells. The purpose of this study was to find out the feasibility of I-131-Iodomisonidazole (IMISO) for imaging of tumor hypoxia. MATERIALS AND METHODS: Tosyl precursor was dissolved in acetonitrile and I-131-NaI was added to synthesize IMISO. Balb/c mice inoculated with CT-26 adenocarcinoma were injected with IMISO. Mice were sacrificed at 1,2,4,24 hr and % of injected dose per gram of tissue (%ID/g) was determined. For scintigraphy and MRI, mouse bearing CT-26 adenocarcinoma was administered with IMISO and imaging was performed 4 hr after. Then, mouse body was fixed and microtomized slice was placed on radiographic film for autoradiography. RESULTS: %ID/g of tumor was 1.64 (1h), 0.98 (2h), 0.85 (4h) and 0.20 (24h), respectively. At 24h, %ID/g of tumor was higher than that of all other tissues except thyroid. Tumor to muscle ratio increased with time and tumor to blood ratio also increased with time and reached 1.53 at 24 hr. On autoradiogram, tumor was well visualized as an increased activity in central hypoxic area of the tumor which corresponds to the area of high signal intensity on T2-weighted MR image. On scintigraphy, tumor uptake was visualized. CONCLUSION:: This RESULTS suggest that IMISO may have a potential for tumor hypoxia imaging in mouse model. However, further study is needed to improve it's localization in tumor tissue and to achieve acceptable images of tumor hypoxia.

BACKGROUND: Extracellular nucleotides act as agonists to regulate a broad range of physiological processes by interacting with P2 receptors in various tissues including the kidney tubules. This study was undertaken to evaluate the effect of P2 receptor activation on PTH-dependent regulation of phosphate transport in the renal proximal tubular cells. METHODS: Proximal tubular cells were isolated from the rabbit kidney and grown as monolayers on 24 well culture plates. Phosphate uptake was determined by measuring the uptake of radiolabeled phosphate into cell monolayers. Cyclic AMP content was determined by radioimmunoassay using [3H]cAMP assay kit. RESULTS: Activation of P2 receptors with ATP exerted differential effects on phosphate uptake and cAMP generation. In the absence of PTH, it inhibited phosphate uptake and stimulated cAMP generation. In contrast, in the presence of PTH, it attenuated PTH-induced stimulation of cAMP generation and inhibition of phosphate uptake. The profile of the effects of different P2 agonists suggested that P2Y1- and P2Y2-like receptors are involved in the effects of ATP. The effect of ATP to interfere with the PTH-induced regulation was significantly blocked by calphostin C, pertussis toxin or PKC-depletion, whereas, the effects of ATP in the absence of PTH were abolished by indomethacin. CONCLUSION: Our results suggest that PKC-dependent modification of Gi proteins and, subsequently, reduced responsiveness of adenylate cyclases is responsible for the attenuating effect of ATP on the PTH-dependent regulation of phosphate transport in rabbit proximal tubule cells.
