Background: Both Helicobacter pylori (H. pylori) cagA, vacA, iceA genotype and host IL-1B/IL-1RN polymorphisms play a role in determining the clinical consequences of H. pylori infection. This study aimed to investigate whether there might be any combinations of H. pylori cagA, vacA, iceA genotype and host IL-1B/IL-1RN polymorphisms that are particularly associated with the occurrence of gastric carcinoma in Korean patients. Methods: This study population was comprised of 239 patients with H. pylori infection: 122 with gastric carcinoma and 117 with gastritis only. DNA was isolated from gastric biopsy sample and H. pylori cagA, vacA and iceA genotype were determined by PCR. IL-1B-511 polymorphisms were genotyped by PCR-RFLP and IL-1RN polymorphisms were analyzed with variable number of tandom repeat after PCR. Results: H. pylori cagA, vacA, and iceA genotype were not associated with an increased risk for gastric carcinoma. IL-1B-511*T carriers and IL-1RN*2 carriers did not show increased risk for gastric carcinoma. On combination of bacterial/host genotypes, cagA+/IL-1B-511*T carriers and cagA+/IL-1RN*2 carriers, vacA s1/IL-1B-511*T carriers, vacA s1/IL-1RN*2 carriers, vacA m1/IL-1B-511*T carriers, vacA m1/IL-1RN*2 carriers, iceA1/IL-1B-511*T carriers, iceA1/IL-1RN*2 carriers showed no increased risk of gastric carcinoma. Conclusions: Combined H. pylori cagA, vacA, iceA genotype and host IL-1B/IL-1RN polymorphisms shows no increased risk of gastric carcinoma. Therefore, it seems other endogenous or exogenous factors may play more important role in the development of gastric carcinoma in Korean.(Korean J Med 71:24-37, 2006)

Park, Hun Hee,Kim, Myungshin,Lee, Bong-Hee,Lim, Jihyang,Kim, Yonggoo,Lee, Eun Jung,Min, Woo Sung,Kang, Chang Suk,Kim, Won Il,Shim, Sang In,Han, Kyungja Institute for Clinical Science] 2006 Annals of clinical and laboratory science Vol.36 No.1

<P>The quantitative levels of intracellular cytokines IL-4, IL-10, and IFN-gamma (ie, the number of bound PE-conjugated antibody molecules/cell) of leukemic cells and bone marrow T cells (bmT cells) of acute leukemia patients were analyzed by flow cytometry. One hundred, thirty-one (95 AML, 25 ALL, 11 ABL) patients were studied. The leukemic cell IL-4 level was highest in the monocytic AML group (1735 +/- 1056) and lowest in the dysplastic AML group (960 +/- 545). The IFN-gamma level was highest in the acute promyelocytic leukemia (APL) group (495 +/- 159), and lowest in the ALL group (252 +/- 119). The IL-10 level was not significantly different among the diagnosis groups. In bmT cells, the IL-10 level was highest in the dysplastic AML group (972 +/- 1049) and lowest in the APL group (397 +/- 352). The leukemic cell cytokine levels were lowest and bmT cell cytokine levels were highest in the dysplastic AML group. There were no significant correlations of these cytokine levels with 2-yr survival rate, complete remission (CR) rate, or relapse rate. The cytokine levels of bmT cells at the time of CR became normal and were not different among the diagnosis groups. In summary, leukemic cell and bmT cell cytoplasmic expression profiles of IL-4, IL-10, and IFN-gamma are characteristic for each diagnostic group of acute leukemia patients and the profiles of bmT cells are normal at the time of CR.</P>

Purpose: Cold air is a major environmental factor that exacerbates asthma. Transient receptor potential melastatin family member 8 (TRPM8) is a cold-sensing channel expressed in the airway epithelium. However, its role in airway inflammation remains unknown. We investigated the role of TRPM8 in innate immune responses in bronchial epithelial cells and asthmatic subjects. Methods: The TRPM8 mRNA and protein expression on BEAS2B human bronchial epithelial cells was examined by real-time polymerase chain reaction (PCR), immunofluorescence staining and western blotting. Additionally, interleukin (IL)-4, IL-6, IL-8, IL-13, IL-25 and thymic stromal lymphopoietin (TSLP) levels before and after menthol, dexamethasone and N-(4-tert-butylphenyl)-4-(3-chloropyridin-2-yl) piperazine-1-carboxamide (BCTC) treatments were measured via real-time PCR. TRPM8 protein levels in the supernatants of induced sputum from asthmatic subjects and normal control subjects were measured using enzyme-linked immunosorbent assay, and mRNA levels in sputum cell lysates were measured using real-time PCR. Results: Treatment with up to 2 mM menthol dose-dependently increased TRPM8 mRNA and protein in BEAS2B cells compared to untreated cells (P < 0.001) and concomitantly increased IL-25 and TSLP mRNA (P < 0.05), but not IL-33 mRNA. BCTC (10 μM) significantly abolished menthol-induced up-regulation of TRPM8 mRNA and protein and IL-25 and TSLP mRNA (P < 0.01). TRPM8 protein levels were higher in the supernatants of induced sputum from asthmatic subjects (n = 107) than in those from healthy controls (n = 19) (P < 0.001), and IL-25, TSLP and IL-33 mRNA levels were concomitantly increased (P < 0.001). Additionally, TRPM8 mRNA levels correlated strongly with those of IL-25 and TSLP (P < 0.001), and TRPM8 protein levels were significantly higher in bronchodilator-responsive asthmatic subjects than in nonresponders. Conclusions: TRPM8 may be involved in the airway epithelial cell innate immune response and a molecular target for the treatment of asthma.

Epigallocatechin-3-gallate protects toluene diisocyanate-induced airway inflammation in a murine model of asthma

Kim, Seung-Hun,Park, Hee-Ju,Lee, Chang-Min,Choi, Il-Whan,Moon, Dong-Oh,Roh, Hwan-Jung,Lee, Hern-Ku,Park, Yeong-Min Elsevier 2006 FEBS letters Vol.580 No.7

<P><B>Abstract</B></P><P>Epigallocatechin-3-gallate (EGCG), a major form of tea catechin, has anti-allergic properties. To elucidate the anti-allergic mechanisms of EGCG, we investigated its regulation of matrix metalloproteinase (MMP-9) expression in toluene diisocyanate (TDI)-inhalation lung tissues as well as TNF-α and Th2 cytokine (IL-5) production in BAL fluid. Compared with untreated asthmatic mice those administrated with EGCG had significantly reduced asthmatic reaction. Also, increased reactive oxygen species (ROS) generation by TDI inhalation was diminished by administration of EGCG in BAL fluid. These results suggest that EGCG regulates inflammatory cell migration possibly by suppressing MMP-9 production and ROS generation, and indicate that EGCG may be useful as an adjuvant therapy for bronchial asthma.</P>

We observed the 57Fe Mo¨ssbauer spectra and Fourier transformation infrared spectra & X-ray fluorescence spectra of lithium nitrosylpentacyanoferrates(Ⅱ) (Li₂[Fe(CN)5NO]·4H₂O, Li₂NP) and cesium nitrosylpentacyanoferrates(Ⅱ) (Cs₂[Fe(CN)5NO]·H₂O, Cs₂NP) samples which comprise nitrosylpentacyanoferrates(Ⅱ) anions with a Fe atom center. The Mo¨ssbauer parameters, values of isomer shift and quadrupole splitting have been measured at room temperature and liquid nitrogen temperature. Also the Mo¨ssbauer Lamb factors of all samples have been measured at room temperature. We have drawn the experimental line width of the Mo¨ssbauer lines normalized to natural line width Γn versus effective thickness of 57Fe.

Purpose: To show various MR spectroscopy and correlated pathologic images of retinoblastoma in nude mouse with a new human retinoblastom cell line (SNUOT-Rbl) which innoculated into intravitreous cavity. Materials and Methods: The established cell line was innoculated into mtravitreous cavity of 14 eyeballs of 7 mice and a transplanted retinoblastoma was examed for 1 month. Tl-weighted image (T1WI), T2-weihgted image (T2WI), and MR spectroscopy were obtained with 1.5 Tesla MRI (Magnetom Vision, Siemens, Erlangen, Germany) and 4.7 Tesla MRI (Bruker, Medizintechnik GmbH, Karlsruhe-Ettlingen, Germany). After scanning, eyeballs were extracted and hematoxylin & eosin stained specimens were examined with the microscope. We compared MR spectroscopy with pathologic findings and evaluated characters of tumors. Results: Innoculated cells into eyeball of mice grew retinoblastoma (8/14, 57%). Eyeball with retinoblastoma protruded externally and showed focal hemorrhage. Tumors showed low (n=3), iso (n=4), high (n=1) signal intensity on TIWI, low (n=5), iso (n=1), high (n=2) signal intensity on T2WI, and well enhancement (n=8) with contrast, Involvement of optic nerve was suspected by MRI and confirmed by pathology (n=1). Conclusion: We could demonstrate MR spectroscopy of transplanted retinoblastoma by new tumor cell line in vivo. This imaging technique facilitate molecular imaging investigation of retinoblastoma.

Hepatocellular carcinoma(HCC)is one of common causes of cancer-related death in Korea where the majority of HCC patients were Hepaitc B virus(HBV)carriers and have cirrhosis. Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.

Scoparone from Artemisia capillaris Inhibits the Release of Inflammatory Mediators in RAW 264.7 Cells upon Stimulation Cells by Interferon-γ Plus LPS

Seon Il Jang,Young-Jun Kim,Woo-Yiel Lee,Kyung Chell Kwak,Seung Hwa Baek,Gyu Beum Kwak,Young-Gab Yun,Tae-Oh Kwon,Hun Taeg Chung,Kyu-Yun Chai 대한약학회 2005 Archives of Pharmacal Research Vol.28 No.2

Scoparone is a major component of the shoot of Artemisia capillaris (Compositae), which has been used for the treatment of hepatitis and biliary tract infection in oriental countries. In the present study we observed that, scorparone exhibited no cytotoxic effect in unstimulated macrophages, but reduced the release of nitric oxide (NO) and prostaglandin E2 (PGE2) upon stimulation by IFN-γ/LPS or LPS. The inhibitory effects were found to be in conjuction with the suppression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in IFN-γ/LPS stimulated RAW 264.7 cells. Moreover, scoparone also attenuated the production of tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6 in LPS-stimulated RAW264.7 cells. These results suggest that scoparone decreases the production of the inflammatory mediators such as NO and PGE2 in macrophages by inhibiting iNOS and COX-2 expression.

Lilium lancifolium (LL) is widely cultivated in East Asia and used to attenuate airway diseases. Our current study aimed to investigate the therapeutic effect of LL on pain level and inflammatory response in a rat model of monosodium iodoacetate (MIA)-induced osteoarthritis (OA). We first examined the effect of LL on inflammatory cytokines and inflammatory mediators in IL-1β-treated HTB-94 cells. The LL extract was found to significantly inhibit the levels of Interleukin-6 (IL-6), Interleukin-8 (IL-8), and prostaglandin-E2 (PGE-2) in Interleukin-1 β (IL-1β)-stimulated HTB-94 cells in a dose-dependent manner. Moreover, chronic oral administration of LL effectively restored the weight-bearing distribution in the rat model of MIA-induced OA. In addition, administration of LL inhibited inflammatory cytokines and inflammatory mediators, such as C-reactive protein (CRP), IL-6, leukotriene B4 (LTB-4), PGE-2, and matrix metalloproteinase-9 (MMP-9). Our findings collectively suggested LL as one of the potential therapeutic agents for OA, owing to its properties of reducing pain and inflammatory responses.
