ABSTRACT
Background@#The study was planned to show the status of indoor microorganisms and the status of the reduction device in the military dog clinic. @*Methods@#Airborne microbes were analyzed according to the number of daily patient canines. For identification of bacteria, sampled bacteria was identified using VITEK®2 and molecular method. The status of indoor microorganisms according to the operation of the ventilation system was analyzed. @*Results@#Airborne bacteria and fungi concentrations were 1000.6 ± 800.7 CFU/m3 and 324.7 ± 245.8 CFU/m3. In the analysis using automated identification system, based on fluorescence biochemical test, VITEK®2, mainly human pathogenic bacteria were identified. The three most frequently isolated genera were Kocuria (26.6%), Staphylococcus (24.48%), and Granulicatella (12.7%). The results analyzed by molecular method were detected in the order of Kocuria (22.6%), followed by Macrococcus (18.1%), Glutamicibacter (11.1%), and so on. When the ventilation system was operated appropriately, the airborne bacteria and fungi level were significantly decreased. @*Conclusion@#Airborne bacteria in the clinic tend to increase with the number of canines. Human pathogenic bacteria were mainly detected in VITEK®2, and relatively various bacteria were detected in molecular analysis. A decrease in the level of bacteria and fungi was observed with proper operation of the ventilation system.

ABSTRACT
PURPOSE: The purpose of the study was to evaluate the accuracy of two different fluid intake measurement methods (fluid only vs. all dietary intake) in measuring fluid balance compared to body weight change among patients with cancers. METHODS: A total of 60 cancer patients in an urban cancer center in South Korea participated in the study. Adult patients who were over 18 years old; having 24-hr I&O order; and taking either normal regular diet or soft blend diet were included. Demographic information and disease related information were also gathered. The data were analyzed using SPSS 18.0 program. RESULTS: Measuring 'fluid only' for oral intake was a more accurate measure than measuring 'all dietary intake' (p=.026 vs. p=.094). Both methods had positive correlations with the amount of weight change (r=.329, p=.010; r=.303, p=.019). Measuring body weight was a more accurate and efficient way of evaluating the fluid balance than 24 hr cumulative I&O. CONCLUSION: Developing clinical manual for selecting proper patients who needs fluid balance monitoring is imperative. Administering weight check and/or 24 hr cumulative I&O should be considered thoroughly based on solid nursing evidence in future.

Our previous works have shown that human thyroid follicular cells from Graves' disease and FRTL-5 rat thyroid cells express the intercellular adhesion molecule-1 (ICAM-1) molecule and its expression is upregulated by several cytokines, interferon-gamma, tumor necrosis factor-alpha, interleukin-1 beta and interleukin-6. We used FRTL-5 cells which show hormonal dependence of growth and function for the study of hormonal regulation of ICAM-1 gene, We studied ICAM-1 mRNA expression and promoter regulation after cloning of rat ICAM-1 promoter. We found very interesting findings that thyroid stimulating hormone (TSH) and forskolin downregulates steady state MHC class land ICAM-1 mRNA levels in FRTL-5 cells; furthermore, TSH/cAMP inhibit cytokines (interferon-gamma,tumor necrosis factor-alpha)-mediated maximal ICAM-1 mRNA expression, In addition, hydrocortisone and insulin differentially regulate the ICAM-1 mRNA levels; hydrocortisone markedly suppresses the mRNA level but insulin partially recovers hydrocortisone mediated ICAM-1 suppression, The interferon-gamma and tumor necrosis factor-alpha increases full ICAM-1 promoter (pCAM-1822) activity and this cytokine mediated increase of the promoter activity is also inhibited by TSH and forskolin, Thus TSH/cAMP pathways play roles as a antagonistic action for maximal expression of ICAM-1 gene by these cytokines. We propose this TSH action is one of physiologic mechanisms to preserve self tolerance in face of abnormal cytokine challenges in systemic inflammatory condition or acute phase response.

Background: TSH binding inhibiting imunoglobulins(TBII) are autoimmune antibody causing autoimmune thyroid diseases such as Graves disease or Hashimoto's thyroiditis, while intercellular adhesion molecule-1(ICAM-1) is known as a substance expressed at the site of autoimmune reaction in relation with lymphocyte infiltration. The serum TBII activity is used as an index of the disease course and prognosis of Graves disease treated with antithyroid drugs, propylthiouracil or methimazole. The aim of this study is to understand the change of serum ICAM-1 level according to the change of the degree of autoimmunity and clinical course of Graves disease. Methods: In order to study the change of soluble ICAM-1 and relationship to the immune mechanism of Graves' disease, we measured serum levels of TBII and ICAM-1 in patients(n 35) with Graves disease before and after treatment with antithyroid drugs and in relapsed patients using a highly sensitive ELISA method. Results: The serum levels of TBII and ICAM-1 were markedly elevated in patients with Graves disease before treatment than normal controls and there were good correlation between TBII and ICAM-1 level. In patients with normalized TBII levels after 22 months antithyroid drug treatment, the ICAM-1 levels became normal but in the patients with high serum TBII level showed high serum level of ICAM-1 even with clinical remission with same treatment. The serum levels of TBII and ICAM-1 in relapsed patients were elevated as those of patients before treatment. Conclusion: With the above results, we can conclude that not only the TBII level but seru ICAM-1 level also reflect the degree of autoimmune activity of Graves disease and may be used as an index of the disease course and prognosis of Graves disease treated with antithyroid drugs.

Intercellular Adhesion Molecule-1(ICAM-1) plays an important role in a variety of inflammatory and immune-mediated mechanisms, including lymphocyte recruitment and targeting, antigen presentation and recognition, and lymphocyte cytotoxicity.In order to study the changes of soluble ICAM-1 and relationship to the immune mechanism of Graves' disease, we performed the measurement of a soluble form of ICAM-1 in sera from patients with Graves' disease before and after treatment with antithyroid drugs using a highly sensitive ELISA method.Our results were as followed.1) The serum levels of soluble ICAM-1 in patients with Graves' disease before treatment were significantly elevated than normal controls(p0.2).4) The serum levels of soluble ICAM-1 showed no significant correlation with serum titers of anti-thyroperoxidase antibody and anti-thyroglobulin antibody, serum T_3, T_4, TSH and goiter size in patients with Graves' disease.In conclusion, the soluble ICAM-1 levels reflect the activity of autoimmune reaction and might be used as a index of efficacy of antithyroid drug treatment of Graves' disease.

The purpose of the present study was to define the normal range of plasma concentration of angiotensin I-converting enzyme(ACE), N-acetyl-b-D-glucosaminidase(NAG), inactive and active renin, and atrial natriuretic peptide(ANP) in normal Korean adult male in terms of aging. Both plasma ACE activity and NAG concentration were measured by spectrofluorometry, and the plasma renin activity and ANP concentration were measured using radioimmunoassay. The ACE was 67.7+-3.6 nM His-Leu/min/ml and did not change in terms of age. The plasma NAG activity tended to decrease. Both plasma active and inactive renin activities were 2.1+-0.2 and 3.0+-0.3 ngAI/ml/h and tended to decrease in terms of aging. The percentage of inactive renin to total renin was 57.2+-2.9% at age 21-30 and also tended to decrease in terms of aging. Plasma ANP concentration at age 22 was 59.6+-2.9 pg/ml.
