A case of optic nerve glioma is presented. This 11 years old Korean boy was seen because of proto nasion of the risht eye ball of 2 months duration. Vision of the right eye was reduced to 20/30 and optic disc showed blurring of the margin with some venous engorgement. Visual field showed enlarged blind spot of Mariotte and contraction of temporal field of vision in the right eye. Radiograpic study of the optic foramina was normal. There was no cafe-au-lait spot. On April 19. 1967. the orbit was exposed through anterior approach because of the tumor possibly invading the intraocular pertion. On operating procedure it was easy to remove the tumor and optic nerve by aspiration of 3 cc. of vitreous using 19 gauge needle. We confirmed a diagnosis of astrocytoma of the optic nerve in pathologic study. A year later the removal of the tumor, the patient was in good health and there had been no recurrence. A review of the literature of recent years related to glioma of the optic nerve, particularly its signs, symptoms, diagnosis and treatment was added.

The purpose of this study is to identify the effects of the supportive nursing care for arthritis patients enrolled in a rheumatoid clinic. To achieve this purpose, this study adopted a quasi-experimental, pre- and post-test research design, categorized subjects into experimental and control groups. Outpatient clinic nurse alloted the subjects by experimental and control groups and nurse researcher meets the experimental subject with in-depth, direct personal interview and advices via telephone for 8 weeks. During this pre and after the treatment period, the level of pain, uncertainty, self-efficacy, family support, and perception for health were measured. Analyses for the measured results for pre- and post-test showed that the supportive program conducted during this study decreased the level of uncertainty and increased the perception of family support in experimental group. So, the supportive healing interpersonal communication service proved to be effective and this result justifies the argument that the role of the nursing professionals at out-patient clinic should be extended for the more qualified care for the patient.

Phase-partitioning with Triton X-114 (TX114) was applied to the TSP antigen, which may be preferentially associated with the cell wall of M. tuberculosis. The hydrophilic protein components of the TSP antigen were successfully separated from integral hydrophobic macromolecules. To further characterize and examine the cellular immune response of the aqueous fraction of the TSP antigen (TSPa), the in vitro properties of the antigen were measured by lymphoproliferation; surface expression of IL-2 Ra on T lymphocytes was analyzed by flow cytometry; and the cytokine mRNA expression pattern was determined by RT-PCR. Significant lymphoproliferative responses to the TSPa antigen were observed in healthy tuberculin reactive donors after a 5 day in vitro stimulation. TSPa treatment of PBMCs from healthy tuberculin positive subjects for 5 days resulted in progressive augmentation of IFN-r, II 2, and IL-2Ra mRNA expression, as measured by RT-PCR, but considerably reduced IL-4 mRNA expression. In addition, the TSPa antigen stimulated more IL-12 p40 mRNA production than did the PPD antigen, and graduaBy suppressed IL- 10 mRNA expression. Moreover, the CD3' T cells of tuberculin positive subjects displayed a profound increase in their expression of the II 2Ru protein (39.0%) in response to the TSPa antigen. Proliferation was correlated with IL-2 and IL-2Ra mRNAs, but not correlated with distinct IFN-r or IL-12 p40 mRNA production. These findings strongly suggest that the TSPa antigen preferentially evokes the generation of a Thl-like immune response in healthy tuberculin reactors.

Tumor-draining lymph node mononuclear (TDLMN) cells are specifically sensitized to the growing tumor but such cells are deficient for mediating an antitumor response. In this study, we examined the feasibility of using mycobacterial 30 kDa or Triton X-100 solubilized protein (TSP) antigen to stimulate mononuclear cells of colon cancer-draining lymph node for the generation of cell mediated immune effector cells. The proliferative response of TDLMN cells stimulated with mycobacterial 30 kDa or TSP antigen was determined by H-thymidine incorporation assay. The proliferation of TDLMN cells to mycobacterial 30 kDa or TSP antigen was significantly increased in PPD (+) patients, but a poor response to the 30 kDa or TSP antigen was observed in PPD (-). The expression on ro T cells to mycobacterial 30 kDa or TSP antigen was assessed by flow cytometry. The ro T cells from PPD (+) patient responded only to 30 kDa antigen but to TSP antigen. An investigation of cytokine mRNA expression was undertaken using reverse transcription- polymerase chain reaction (RT-PCR) to follow TDLMN cells stimulated with the 30 kDa or TSP antigens for 5 days. The IFN-r and TNF-a mRNA expression was only induced in TDLMN cells of PPD (+) patient in response to the 30 kDa or TSP antigen. The IL-2 mRNA expression was induced in both PPD (+) and PPD (-) in response to the 30 kDa or TSP antigen. But the IL-4 mRNA expression was not induced in response to the 30 kDa or TSP antigen. These results suggest that the 30 kDa and TSP antigens may serve as biologic response modifier for the generation of cell mediated immune effector cells.

Background: Primary squamous cell carcinoma (SCC) of the salivary gland is a rare disease, and distinguishing primary SCC from metastatic SCC is difficult. This study investigated the histological and immunohistochemical differences between primary and metastatic salivary gland SCC to improve the accuracy of diagnosis and to explore the pathogenesis of this disease. Methods: Data of 16 patients who underwent surgery for SCC of salivary glands between 2000 and 2018 at Asan Medical Center were retrieved. Eight patients had a history of SCC at other sites, and eight patients had only salivary gland SCC. Immunostaining for p16, p53, androgen receptor (AR), gross cystic disease fluid protein 15 (GCDFP-15), and c-erbB2, as well as mucicarmine staining, were compared between the two groups. Results: Most tumors were located in the center of the salivary glands with extraparenchymal extension. The histology of primary SCC of the salivary gland was consistent with moderately differentiated SCC with extensive desmoplastic reaction and peritumoral inflammation. Involvement of the salivary gland ducts and transition into the ductal epithelium were observed in two cases. Metastatic SCC resembled the primary tumor histologically and was associated with central necrosis. Both groups exhibited negative mucin staining. Two, one, and one primary SCC case exhibited AR, GCDFP-15, and c-erbB2 positivity, respectively. Conclusions A subset of primary SCCs originated in salivary ducts or was related to salivary duct carcinoma. Distinguishing primary from metastatic SCC of the salivary gland is difficult using histologic features and immunoprofiles. A comprehensive review of the medical history is essential.

BACKGROUND: We have recently shown that lipopolysaccharide (LPS), a major biologically active component of Gram-negative bacteria, mediate the activation of human keratinocytes by CD14 and Toll-like receptor (TLR 4). However, the mechanism of activation of keratinocytes by Gram-positive bacterial toxins remains unclear. OBJECTIVE: We investigated the mechanism of activation of human keratinocytes by lipoteichoic acid (LTA), a main stimulatory component of Gram-positive bacteria. METHODS: The effects of LTA on CD14, TLR2 and TLR4 mRNA expression were measured by quantitative RT-PCR in cultured human keratinocytes. To determine whether the effects of LTA on CD14, TLR2 and TLR4 expressions of the human keratinocytes were biologically functional, NF-kappaB nuclear translocation and IL-1alpha secretion were measured by immunofluorescence staining and ELISA, respectively. Furthermore, to determine whether these effects by LTA were specific for CD14, TLR2 and TLR4, some cells were pretreated with anti-CD14, anti-TLR2, or anti-TLR2 monoclonal antibodies prior to the addition of LTA. RESULTS: TLR4 mRNA expression on keratinocytes was augmented by exposure to LTA. LTA binding to keratinocytes resulted in NF-kappaB nuclear translocation and secretion of interleukin-1alpha. These responses by LTA were effectively abrogated by preincubating cells with anti-TLR4 monoclonal antibody, but not with anti-CD14 or anti- TLR2 monoclonal antibodies. CONCLUSION: These results indicate that, similar to LPS, LTA induces activation of human keratinocytes mainly through TLR4, however, in contrast to LPS signaling, LTA-induced keratinocyte activation is CD14-independent.

PURPOSE: The aim of this study was to examine characteristics of health-related victims identified through the Surveillance System of Heat-related Illness (SSHI) based on emergency department (ED) visits. METHODS: Between July 1 and September 3 of 2011, 443 heat-related patients were reported by 396 of the 461 EDs participating in the SSHI. Heat-related illness included heat (sun) stroke, heat cramp, heat syncope, and heat exhaustion. A hot day was defined as a day above 30degrees C of daily maximum temperature in locations of provincial and metropolitan government offices. We used chi square test for identification of risk factors associated with Heat-related illness in the workplace and heat-related illness heat (sun) stroke. RESULTS: Heatwave, defined as lasting three or more hot days, occurred three times during this period. The daily average number of heat-related patients reported during the heatwave period was 15.7 per day, more than four times the usual rate. The daily maximum temperature showed positive correlation with occurrence of heat-related illness. Heat exhaustion was the most frequent cause (46.0%), with approximately 70% of all cases occurring between noon and 6 p.m. The number of people suffering from heat-related illness while outdoors was three times greater than that of those who experienced it indoors. Work-related occurrence comprised 56.7% of all cases. All six deaths occurred during the heatwave period and were work-related. CONCLUSION: Working conditions, outdoor activities, and old age may be associated with health-related illnesses. A surveillance system that monitors emergency room visits may be useful in assessment of adverse health effects of summer heatwaves.

Present study was aimed to investigate the immunological activities of the 47 kDa glycoprotein antigen from Treponema pallidum and conducted on 24 patients with syphilis, (early, late, spontaneously healed, congenital and treated patients) and on 17 normal healthy controls. Two opposite lymphoproliferative manifestations to the 47 kDa antigen were observed in syphilis patients by H-thymidine incorporation assay. Ten responders (stimulation index [Sl] >4) showed a 3-fold-higher proliferation than the nonresponders, and four of those responders were spontaneously healed patients. Furthermore, analysis by flow cytometry indicated a preferential expansion of CD4' T lymphocytes by the 47 kDa antigen in the spontaneously healed syphilis patients. Stimulation of PBMCs of spontaneously healed syphilis patients with the 47 kDa antigen for greater than 72 hrs resulted in piogressive augmentation of IFN-r, IL-2Ra and IL-2 mRNA measured by RT-PCR, but considerably reduced IL-4 and IL-10 mRNA expression. However, patients with late latent syphilis exhibited more increased IL-4 and IL-10 mRNA expressions in response to the 47 kDa antigen than spontaneously healed syphilis group. In contrast to other groups, when cultured with the 47 kDa antigen very low IFN-#y, IL-2Ra and IL-2 mRNA expressions were shown in early syphilis group. These data suggest that the Th1-predominant cellular responses induced by the 47 kDa antigen may be involved in the clinical outcome of syphilis and provide the immunologic basis for further functional studies regarding the role of the 47 kDa in the immunopathogenesis of syphilis.

PURPOSE: The cisplatin and etoposide had been reported to be an effective anti-tumor drug for small cell lung cancer, ovarian cancer, breast cancer and so on. The aim of this study was to evaluate the stability of cisplatin and etoposide in aqueous solution. MATERIALS AND METHODS: Cisplatin 200 microgram/ml was prepared in 0.9% sodium chloride and stored in either glass bottle or polyvinyl chloride (pvc) bag and protected from light or exposed to fluorescent light. Etoposide solution was prepared in 0.9% sodium chloride, and contained in glass bottle. Precipitating concentration was achieved using 200 microgram/ml, 400microgram/ml, 600 microgram/ml, and 1000 microgram/ml of etoposide solution. Samples were stored at room temperature and visually inspected and assayed for etoposide and cisplatin content by high-performance liquid chromatography after 15 minutes, 2, 4, 8, 12, 16 and 24 hours of storage. RESULT: 1) Cisplatin concentration decreased less than 10% from initial concentration for 24 hours of storage, both in glass bottle and pvc bag. Stability of cisplatin 200 microgram/ml in both container were not different. and Condition of light exposure did not have significant effect on stability of cisplatin 200 microgram/ml in glass bottle. 2) The etoposide 200 microgram/ml was not precipitated and stable for 24 hours, but we could find the precipitates of etoposide with the concentration of 400 microgram/ml or higher for 24 hours. CONCLUSION: Cisplatin 200 microgram/ml and etoposide 200 microgram/ml in 0.9% sodium chloride were stable at room temperature under room fluorescent light for 24 hours.
