Purpose: This study was performed to evaluate the anti-inflammatory effect of Eungapbang extract (EGB). Methods: To evaluate the anti-inflammatory effects of EGB, we nourished RAW 264.7 cell lines in the laboratory dish. Next, inflammatory cytokine concentrations were analyzed. Then, sera were prepared from blood after lipopolysaccharide (LPS) injection in chemically induced mouse models of intestinal inflammation, and Interleukin-1${\beta}$ (IL-1${\beta}$), interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-${\alpha}$) were measured using ELISA kits. Results: 1. EGB significantly suppressed the expression levels of IL-1${\beta}$ and NOS-II genes at 100, 50 and 10 ${\mu}g/m{\ell}$ concentrations, and IL-6, TNF-${\alpha}$ and COX-2 mRNAs at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 2. EGB significantly reduced the production level of IL-1${\beta}$ and TNF-${\alpha}$ at 100${\mu}g/m{\ell}$ concentrations, and IL-6 at 100 and 50 ${\mu}g/m{\ell}$ concentrations. 3. EGB significantly decreased the production level of IL-1${\beta}$ and IL-6 in sera of acute inflammation induced mice. 4. EGB could suppress the expression level of IL-1${\beta}$ and IL-6 mRNA in spleen tissues in acute inflammation induced mice. Conclusion: On the basis of the above results, it is confirmed that the anti-inflammatory effects of EGB were recognized. Therefore, EGB is recommended as promising therapy for treatment of such ailments as pelvic inflammatory disease.

This study was conducted to observe the influences of Crataegus pinnatifida BUNGE extract on lipid concentration in hypercholesterolemic rats (Sprague Dawley, male) fed the experimental diets for 5 weeks. Body weight gain was remarkably lower in the Crataegus pinnatifida BUNGE extract intake group than in the hypercholesterolemic rats. Total cholesterol concentration was remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Whereas, concentrations of HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol were remarkably higher in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Atherosclerotic index (AI), cardiac risk factor (CRF) were remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. From the above research, Crataegus pinnatifida BUNGE extract was effective on the lipid concentrations in sera of dietary hypercholesterolemic rats.

Collagen-induced arthritis (CIA) is a model for some types of human autoimmune rheumatoid arthritis (RA). In this study, we examined whether ethanol extract of potato (Solanum tuberosum) is efficacious against CIA in mice. Potato extracts (100 and 200 mg/kg) were orally administered to DBA/1J mice once daily for 49 day after initial immunization with type II collagen. Clinical assessment of disease and measurement of paw edema were conducted throughout the study. The production of CIA-related rheumatoid factor, anti-type II collagen antibody, and cytokines were examined in DBA/1J mice. Serum levels of AST, ALT, creatinine, and lipids were measured, and antioxidant enzyme activity in the spleen was also determined. The arthritis score and paw edema were markedly suppressed in the groups treated with potato extract. Levels of rheumatoid factor, anti-type II collagen antibody, interleukin (IL)-1, IL-6, LDL-cholesterol, and malondialdehyde in sera were also reduced by potato extract treatment. The activities of glutathione peroxidase and glutathione reductase were increased in the spleens of CIA mice treated with potato extract. These findings suggest that potato extract has suppressive effects on type II collagen-induced arthritis, an animal model for human RA.

Alterations in the amino acid structure or sequence can generate neo-epitopes from self-proteins causing autoaggressive immune attack. Reactive nitrogen species are an important factor that induces post-translational modification of proteins by cellular reduction and oxidation mechanism; cysteinyl-nitrosylation or tyrosine nitration leading to potentially pathogenic pathways. It was thought of interest to investigate the immunogenicity of nitrated poly L-tyrosine vis-$\`{a}$-vis its possible role in the induction of antibodies in systemic lupus erythematosus (SLE). Commercially available poly L-tyrosine was exposed to nitrating species and the damage was monitored by UV spectroscopy and alkaline gel electrophoresis. The results indicated the formation of 3-nitrotyrosine. Nitrated poly L-tyrosine induced higher titre antibodies as compared to the native form. Nitrated poly L-tyrosine was recognized by the autoantibodies present in the sera of patients suffering from SLE by enzyme immunoassays and band shift assay. The possible role of nitrated self-proteins has been discussed in the production of circulating anti-DNA antibodies in SLE.

The purpose of this study was to investigate the improvement effect of 5% mung bean (phaseolus aureus L.) on the blood glucose and lipid metabolism function of streptozotocin (STZ, 45 mg/kg body weight)-induced diabetic rats. Seven-week-old male rats were divided into four groups (n=6), and fed experimental diets containing mung bean meal [basal diet+5% mung bean (BM), basal diet+STZ+5% mung bean (SM)], and control (BD), BS groups (basal diet+STZ). The results of this study, mung bean diet groups (BM, SM) in lipid composition evidenced the significantly reduction of serum total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), atherosclerotic index (AI), cardiac risk factor (CRF), triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester, uric acid, blood glucose, non esterified fatty acid (NEFA), and elevation of high density lipoprotein-cholesterol (HDL-cholesterol). The serum albumin/globulin ratio (A/G ratio) was increased in mung bean supplementation diet than STZ-induced diabetic rats (p<0.05). Concentrations of sodium (Na) and chlorine (Cl) in sera were lower in the mung bean diet than diabetic group. Total calcium (T-Ca), phosphorus (Pi) and potassium (K) concentrations in sera were higher in the BM, SM and BD groups than BS group. In vivo experiments with Sprague-Dawley rats showed that ingestion of mung bean (phaseolus aureus L.) were effective in blood glucose and lipid composition.

This study aimed to investigate the improvement effect of turmeric (Curcuma longa L.) on the lipid component, protein and electrolyte concentration in dyslipidemic rats. Sprague-Dawley rats (24 male) were divided into four groups, namely the ND (normal-nondyslipidemic diet), NT (normal-nondyslipidemic diet+5% turmeric), DD (control-dyslipidemic diet), and DT groups (dyslipidemic diet+5% turmeric). Rats were sacrificed at the end of 5 weeks after experiment diet. In this study, turmeric diet (NT, DT) groups in lipid composition as evidenced from the significantly reduction of serum total cholesterol, low density lipoprotein-cholesterol (LDL-cholesterol), atherosclerotic index (AI), cardiac risk factor (CRF), triglyceride (TG), phospholipid (PL), free cholesterol, cholesteryl ester, blood glucose and non esterified fatty acid (NEFA), and elevation of high density lipoprotein-cholesterol (HDL-cholesterol) (p<0.05). The serum globulin concentration was significantly decreased (p<0.05), and the albumin concentrations were increased in turmeric diet than dyslipidemic rats. Concentrations of sodium (Na) and chlorine (Cl) in sera were lower in the DT group than DD group. Concentrations of total calcium (T-Ca), phosphorus (Pi) and potassium (K) in sera were higher in the ND, NT and DT groups than DD group. Therefore, it was concluded that the 5% turmeric diet used in the condition of this study had a beneficial effect on dyslipidemia.

Purpose: Renal involvement is the most important prognostic factor of HSP. Therefore, the pathogenesis and prognostic factors in renal involvement have been studied by many researchers. The aim of this study was to evaluate the clinical risk factors and the role of TNF-$\alpha$ in renal involvement of HS purpura. Methods: The subjects of this study were 12 patients of HS purpura, 7 patients of HS nephritis, and 5 age-matched controls. We have analysed the rist factors for renal involvement in clinical symptoms and collected the sera and urines of all subjects in acute and convalescent stage. The concentration of TNF-$\alpha$ in the collected sera and urines were measured by sandwich ELISA and compared with that of age-matched controls. Results: Statistical analysis showed that persistent purpura increased the risk of developing renal involvement (P=0.0018). and serum TNF-$\alpha$ levels in the acute stage of patients with renal involvement($11.45{\pm}7.01$ pg/ml) were significantly higher than those of without renal involvement($6.32{\pm}1.31$pg/m1) and of age-matched controls($5.99{\pm}1.34$pg/m1)(P=0.012, 0.027, respectively). However, urine TNF-$\alpha$ levels have no correlation with renal involvement. On investigation of serum TNF-$\alpha$ levels in acute stage of HS purpura, persistent purpura had a significantly higher increase(P=0.038). Conclusion: Serum concentration of TNF-$\alpha$ is a risk factor and has a predictable value along with clinical risk factors, such as, persistent purpura for renal involvement in HS purpura. Also, the effectiveness of the specific treatment fur antagonizing TNF-$\alpha$ in HS nephritis may need further study.

Purpose : It is not clear that the development of glomerular injury and aggravation by tumor necrosis factor alpha($TNF-{\alpha}$) is related to intrarenal or serum concentration of $TNF-{\alpha}$. So, we studied the relationship between the concentration of $TNF-{\alpha}$ and aggravation of glomerular damage in the Henoch-$Sch{\ddot{o}}nlein$ nephritis(HSN) and idiopathic nephrotic syndrome(INS). Methods : We collected the sera and urines of 21 patients with Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) and 22 patients with INS visited Chungbuk National University hospital from March 1998 to March 2001. The concentration of $TNF-{\alpha}$ in the sera and urines were measured by sandwich ELISA. Results : Serum $TNF-{\alpha}$ levels in the HSP patients with renal involvement were significantly higher than those without renal involvement(P=0.009). But urine $TNF-{\alpha}$ levels have no correlation with renal involvement(P=0.088). In the HSN patients, proteinuria have a significant correlation with serum $TNF-{\alpha}$ levels(P=0.004) but less correlation with urine $TNF-{\alpha}$ levels(P=0.053). Otherwise, proteinuria have no correlation with serum $TNF-{\alpha}$ levels(P=0.763) but have a significant correlation with urine $TNF-{\alpha}$ levels(P=0.007) in INS. Conclusion : These result suggest that the serum concentration of $TNF-{\alpha}$ would be important to glomerular involvement in HSP. And, it is interesting that proteinuria shows a significant relation with serum $TNF-{\alpha}$ levels in the HSN, but with urine $TNF-{\alpha}$ levels in the INS. This means the major production of $TNF-{\alpha}$ may be originated by extrarenal inflammation in the HSN and by intrarenal tubulo-interstitial damage due to proteinuria in the INS.

Background: Interleukin-33 (IL-33) has recently been implicated in tumor immunity. The aim of this study was to explore the clinical role of serum IL-33 in patients with non-small-cell lung cancer (NSCLC). Methods: Sera collected from 250 healthy volunteers (HV), 256 patients with benign lung diseases (BLD) and 262 NSCLC cases were subjected to IL-33 ELISA and relationships between serum IL-33 and clinical characteristics were evaluated. Results: Circulating IL-33 levels were higher in the NSCLC group in comparison with the HV and BLD groups (p<0.001). Using a cut-off level 68 pg/ml (95% specificity in the HV group), IL-33 showed a good diagnostic performance for NSCLC. Multivariate survival analysis indicated that serum IL-33 was an independent prognostic factor in the entire NSCLC group [hazards ratio (HR) = 0.64 for low versus high IL-33 levels, 95% confidence interval (CI) 0.50-0.82; p<0.001] and in 165 selected patients with locally advanced or metastatic disease receiving chemoradiotherapy or chemotherapy (HR 0.70, 95% CI 0.52-0.94; p=0.013). Conclusions: IL-33 is a promising potential diagnostic and prognostic marker in NSCLC, independent of the therapeutic intervention.

Although it is well known that rain plays an important role in capturing air pollutants, its quantitative evaluation has not been done enough. In this study, the effect of raindrop size on pollutant scavenging was investigated by clarifying the chemical nature of individual size-resolved raindrops and their residual particles. Raindrops as a function of their size were collected using the raindrop collector devised by our oneself in previous study (Ma et al., 2000) during high atmospheric loading for $PM_{2.5}$. Elemental analyses of solid residues and individual residual particles in raindrops were subsequently analyzed by Particle Induced X-ray Emission (PIXE) and Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDX), respectively. The raindrop number concentration ($m^{-2}h^{-1}$) tended to drastically decrease as the drop size goes up. Particle scavenging rate, $R_{sca.}$ (%), based on the actual measurement values were 38.7, 69.5, and 80.8% for the particles with 0.3-0.5, 0.5-1.0, and $1.0-2.0{\mu}m$ diameter, respectively. S, Ca, Si, and Al ranked relatively high concentration in raindrops, especially small ones. Most of the element showed a continuous decrease in concentration with increasing raindrop diameter. The source profile by factor analysis for the components of residual particles indicated that the rainfall plays a valuable role in scavenging natural as well as artificial particles from the dirty atmosphere.
