A mediastinal mass was aspirated by fluoroscope-guided fine needle aspiration biopsy in a 47 years old female patient. The first aspiration smears were not diagnostic, because of hemorrhagic background and cell paucity. On the second aspiration, the smears were composed of some clusters of benign epithelial cells in hemorrhagic background. Cells were arranged in mostly solid sheets and tended to form glandular lumina in part. Their nuclei were round and vesicular. Nucleoli were not prominent. These findings were suggestive of benign glandular tissue, which was finally confirmed as mediastinal thyroid gland by open thoracotomy specimen.

Nicotinic acetylcholine receptors, a ligand-gated ion c hannels,mediates many important physiological processes. Chronic nicotine admini stration could desensitize nicotinic receptors. Many factors which modulate dese nsitization have been described, including different subunits, agonist, signal t ransduction and cellular microenivornment. The important physiological functions of desensitized receptors still remain controversial, may be modulate synaptic transmission,synapse plasticity and mediate self-protection.

PURPOSE: The purpose of this study was to develop and evaluate a tool to measure job stress related to occupational characteristics of infection control nurses. METHODS: The tool was developed through the steps of literature reviews, preparatory questions, and a test of validity and confidence. The participants were 212 infection control nurses from 145 Korean hospitals. Data were analyzed using descriptive statistics, Cronbach's alpha coefficients, item analysis, factor analysis. RESULTS: Through factor analysis, 38 items in four domains and nine factors were derived. The Cronbach's alpha coefficient of the final instrument was .95. CONCLUSION: The results of this study indicate that the measurement tool is reliable and valid to measure the job stress of infection control nurses.

This experiment was performed to elucidate the cytologic origin of chemically induced MFH in Wistar rats. The tumor was produced by injections of DMBA(9,10-dimethyl-1,2-benzanthracene). With the produced MFH, cell culture and cloning were performed, followed by establishment of a cell strain, which was investigated by immunohistochemical and electron microscopic studies. The results were as follows. A) By immunohistochemistry of the tumor tissue, fibroblastic cells were positive for MEP-1(specific antibody for fibroblastlike cell of MFH, Takeya, 1993) and Anti-hPH(beta)(Anti-prolyl 4-hydroxylase beta), but negative for TRPM-3 and F4/80. Histiocytelike cells were positive for TRPM-3 and F4/80, but negative for MEP-1 and Anti-hPH(beta). In immunoelectron microscopy, normal spleen macrophage showed linear reactivity in cell membrane for TRPM-3, whereas histiocytelike cells of the tumor disclosed negative reaction. B) At 5 weeks of the primary tumor cell culture, the cells exhibited typical storiform pattern of MFH. C) The established cell strain revealed immunoreactivity for MEP-1 and Anti-hPH(beta), but negative for TRPM-3. The cloned tumor cells showed morphologic characteristics of undifferentiated fibroblastic cell. Latex particle (0.80 micrometer size) phagocytosis was negative in the cloned cell strain. The results of the current study support the concept that principal component cells of MFH is of fibroblastic cell origin.
