To investigate effects of cytokines on rheumatoid synovial cells, proliferation and expression of cytokine and metalloproteinase genes were studied with the primary culture of rheumatoid synovial cells which was treated with TNF-alpha, GM-CSF, TGF-alpha, PDGF and IL-B. By [3H] thymidine incorporation assay, TGF-beta and PDGF increased proliferation of synovial cells by 1.5 and 2.5 folds respectively. Cytokine gene expression was assessed by RT-PCR. Rheumatoid synovial cells expressed constitutively TGF-beta and IL-B at a high level and IL-1B, GM-CSF, and MIP-1a at a relatively low level. TGF-beta, GM-CSF and PDGF increased IL-B expression. Expression of pro-inflammatory cytokines and chemokines was increased by GM-CSF and PDGF. Both GM-CSF and PDGF increased the expression of IL-1B, GM-CSF MIP-la and IL-8. In addition, GM-CSF enhanced expression of TNF-alpha. Stromelysin and collagenase are the major proteinases responsible for destruction ot joints in rheumatoid arthritis (RA). These genes were expressed constitutivefy in rheumatoid synovial cells. In summary, PDGF and GM-CSF may piay an important role by inducing or increasing expression of IL-1B, TGF-beta and PDGF by increasing proliferation of rheumatoid synovial cells.

PURPOSE: The effect of PTK inhibitors (herbimycin A and genistein) on the induction of radiation-induce d apoptosis in Ph-positive K562 leukemia cell line was investigated. MATERIALS AND METHODS: K562 cells in exponential growth phase were irradiated with a linear accelerator at room temperature. For 6 MV X-ray irradiation and drug treatment, cultures were initiated at 2x10' cells/mL. The cells were irradiated with 10 Gy. Stock solutions of herbimycin A and genistein were prepared in dimethyl sulphoxide (DMSO). After incubation at 37C for 0-48 h, the extent of apoptosis was determined using agarose gel electrophoresis and TUNEL assay. The progression of cells throughth the cel l cycle after irradiation and drug treatment was also determined with flow cytometry. Western blot analysis was used to monitor bcl-2, bcl-X and bax protein levels. RESULTS: Treatment with 10 Gy X-irradiation did not result in the induction of apoptosis. The HMA alone (500 nM) also failed to induce apoptosis. By contrast, incubation of K562 cells with HMA after irradiation resulted in a substantial induction of nuclear condensation and fragmentation by agarose gel electro-phoresis and TUNEL assay. Genistein failed to enhance the ability of X-irradiation to induce DN A fragmentation. Enhancement of apoptosis by H MA was not attributable to downregulation of the bcl-2 or bcl-X anti-apoptotic proteins. When the cells were irradiated and maintained with HMA, the percentage cf cells in G2/M phase decreased to 30-40% at 48 h. On the other hand, cells exposed to 10 Gy X-irradiation alone or maintained with genistein did not show marked cell cycle redistribution. CONCLUSION: We have shown that nanomolar concentrations of the PTK inhibitor HMA synergize with X-irradiation in inducing the apoptosis in Ph (+) K562 leukemia cell line. While, genistein, a PTK inhibitor which is not selective for p2 10""'' failed to enhance the radiation induced apoptosis in K562 cells. It is unlikely that the ability of HMA to enhance apoptosis in K562 cells is attributable to bcl-2 family. It is plausible that the relationship between cell cycle delays and cell death is essential for drug development based on molecular targeting designed to modify radiation-induced apoptosis.

6.Clinical Features of Advanced Non-Small Cell Lung Cancer in Never-Smokers.
Korean Journal of Medicine 2011;80(4):427-433
BACKGROUND/AIMS: Smoking is major cause of lung cancer. However, the prevalence of lung cancer in never-smokers increasing recently. This study investigated the clinical characteristics of advanced lung cancer in never-smokers. METHODS: We anlyzed the clinical characteristics including demographics, bronchoscopic features, stage, and serum tumor markers, of never smokers with lung cancer seen at Kosin University Hospital from January 2001 to December 2008. RESULTS: There were 105 never smokers with lung cancer (mean age 61 years, 82 females), comprising 83 (79%) adenocarcinomas, 9 (8.6%) squamous carcinomas, and 13 (12.4%) undifferenciated carcinomas. The overall median survival time (MST) was 18.7 months. The MST was longer in females (21.6 vs. 13.7 months, p = 0.03), patients younger than 60 years (19.2 vs. 17.5 , p = 0.019), and those with adenocarcinoma (21.6 vs. 8.8 months, p = 0.038), and a neuron-specific enolase level of less than 15 ng/mL (22.4 vs. 13.4 months, p = 0.014). CONCLUSIONS: We analyzed the clinical characteristics of advanced lung cancer in never smokers. A more comprehensive study is need to compare never-smokers and smokers with lung cancer and to determine the appropriate treatment for non-smokers.

PURPOSE: This study was conducted for the purpose of a structural model analysis of family health of women who came to Korea for being married to Korean men. METHODS: The data were collected from 260 immigrant women at multicultural centers located in C and B cities from May 10th to 30th, 2012. The variance analysis on the samples was conducted by using the maximum likelihood minimization function with AMOS 7.0. The fitness was evaluated by means of the SRMR, RMSEA, CFI, and TLI with a 90% confidence interval. RESULTS: First, immigrant women's self-esteem and acculturative stress were found to have significant direct effects on their family health. Second, their self-esteem and acculturative stress have direct effects on their marital adjustment. Third, their marital adjustment was found to have significant direct effects on their family health. Forth, immigrant women's Korean language ability was found not to have significant direct effects on their marital adjustment and family health. CONCLUSION: In order to enhance the family health of immigrant women, it is necessary to develop and apply nursing programs in consideration of immigrant women's self-esteem, marital adjustment and acculturative stress.

The characteristics of radionuclide brain scan imaging of intracranial lesion are determined, in part, by the rate and quantity of radioactive material in the region of involvement, which is associated with alterations in the blood brain barrier. Findings, noted on the blood flow studies, often serve to direct attention to forthcoming imaging of specific pathological change on the status studies, e.g, carotid artery occlusion and cerebral infarction. We have seen that the 62 year old woman with left side hemiparesis shows typical "Flip-Flap" pattern in brain scan imaging, thought to be due to carotid artery occlusion.

The mineral contents of the cultivation substrates, fruiting bodies of the mushrooms, and the postharvest cultivation substrates were determined in cultivated edible mushrooms Pleurotus eryngii, Flammulina velutipes, and Hypsizigus marmoreus. The major mineral elements both in the cultivation substrates and in the fruiting bodies were K, Mg, Ca, and Na. Potassium was particularly abundant ranging 10~13 g/kg in the cultivation substrates and 26~30 g/kg in the fruiting bodies. On the contrary, the calcium content in the fruiting bodies was very low despite high concentrations in the cultivation substrates, indicating Ca in the cultivation substrates is in a less bio-available form or the mushrooms do not have efficient Ca uptake channels. Among the minor mineral elements determined in this experiment, Cu, Zn, and Ni showed high percentage of transfer from the cultivation substrates to the fruiting bodies. It is noteworthy that the mineral contents in the postharvest cultivation substrates were not changed significantly which implies that the spent cultivation substrates are nutritionally intact in terms of mineral contents and thus can be recycled as mineral sources and animal feeds.

Journal of Pathology and Translational Medicine 2016;50(1):26-36
Tubulointerstitial nephritis (TIN) is the most common form of renal involvement in IgG4-related disease. It is characterized by a dominant infiltrate of IgG4-positive plasma cells in the interstitium and storiform fibrosis. Demonstration of IgG4-positive plasma cells is essential for diagnosis, but the number of IgG4-positive cells and the ratio of IgG4-positive/IgG-positive plasma cells may vary from case to case and depending on the methods of tissue sampling even in the same case. IgG4-positive plasma cells can be seen in TIN associated with systemic lupus erythematosus, Sjogren syndrome, or anti-neutrophil cytoplasmic antibody-associated vasculitis, which further add diagnostic confusion and difficulties. To have a more clear view of IgG4-TIN and to delineate differential points from other TIN with IgG4-positive plasma cell infiltrates, clinical and histological features of IgG4-TIN and its mimickers were reviewed. In the rear part, cases suggesting overlap of IgG4-TIN and its mimickers and glomerulonephritis associated with IgG4-TIN were briefly described.
