  • Purpose: The dried body of Scolopendra subspinipes mutilans has long been used as a traditional Korean medicinal food, but little is known about its mechanisms of action. In this study, we investigated the anti-inflammatory activities of Scolopendra subspinipes mutilans and possible mechanisms in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Methods: Cytotoxicity of Scolopendra subspinipes mutilans extract (SSME) was measured by MTT assay, anti-inflammatory activities were analyzed by nitric oxide (NO) production, the expression of inducible NO synthase (iNOS) and the mRNA level of pro-inflammatory cytokines such as $interleukin-1{\beta}$ ($IL-1{\beta}$) and interleukin-6 (IL-6). Nuclear translocation of nuclear factor-kappa B ($NF-{\kappa}B$) p65 subunit and degradation of inhibitory kappa B ($I{\kappa}B$) were examined by western blot. Results: SSME inhibited LPS-induced NO production and iNOS expression without cytotoxicity. Up-regulation of LPS-induced pro-inflammatory cytokines, $IL-1{\beta}$ and IL-6 was dose dependently attenuated by SSME. Exposure of pyrrolidine dithiocarbamate, an $NF-{\kappa}B$ specific inhibitor, accelerated the inhibitory effects of SSME on NO production and iNOS expression in LPS-stimulated cells. Moreover, translocation of $NF-{\kappa}B$ from the cytosol to the nucleus and degradation of $I{\kappa}B$ were decreased by treatment with SSME in LPS-induced cells. Conclusion: These results suggest that the SSME might have the inhibitory effects on inflammation, partly through inhibition of the $NF-{\kappa}B$ signaling pathway.

  • This study was conducted to identify the characteristics of immune function and inflammatory changes for elderly women, by having them to participate in line dance program. For this purpose, 18 elderly women in their 60s to 70s, living in Y city were selected, and 9 of the participants were randomly assigned to participate in the line dance program for 12-weeks (line dance exercise group), while the other 9 participants were assigned to carry out their daily lives without participating in certain physical activity (control group) for the same period. The subjects' immune function and inflammation were measured using SPSS 24.0 for datafication, and the average and two-way ANOVA analysis were conducted. The result indicates the immunoglobulin, IgA, has increased, but not dramatically. The level of IgG(p<.05), and IgM(p<.05) increase were detected from the line dance exercise group, but not so much from the control group. Inflammation indicator, the CRP(p<.05), were significantly reduced from the line dance exercise group, but not much for the control group. According to the collected data, line dance for the elderly women can be considered as an effective exercise program, and the result shows that inflammation is reduced and immune function is improved. It also implies the needs of active physical activity arbitration to keep the elderly women's health and to prevent the chronic disease in the future.

  • Objectives: The aim of this study is to determine arterial stiffness levels as measured by brachial-ankle pulse wave velocity (baPWV) and to identify the association between arterial stiffness and inflammatory markers, in healthy adults over 50 years old. Methods: The study population consisted of 4617 persons over the age of 50 years who participated in the baseline survey of the Dong-gu Study, which was conducted in 2007 and 2008. Arterial stiffness was measured using baPWV. A multiple regression analysis was performed to assess the relationship between conventional cardiovascular risk factors and inflammatory markers, including white blood cell (WBC) counts, high-sensitive C-reactive protein (hs-CRP), and gamma glutamyltransferase (GGT). Results: After adjustment for conventional cardiovascular risk factors including sex, age, smoking status, body mass index, systolic blood pressure, fasting glucose, hypertension or diabetic medication, total cholesterol, triglycerides, uric acid, and alanine aminotransferase, baPWV was significantly associated with WBC counts (${\beta}$=0.158, p<0.0001), hs-CRP (${\beta}$=0.244, p=0.026), and GGT (${\beta}$=0.003, p<0.0001). Conclusion: This study shows that arterial stiffness correlates with inflammatory markers. Arterial stiffness may be used as a composite risk factor to identify persons with higher risk for cardiovascular disease. Additionally, arterial stiffness may be a marker for future cardiovascular disease and a target for prevention.

  • Allergic contact dermatitis (ACD) is an inflammatory skin disease and regarded as a prototype of T-cell mediated delayed-type hypersensitivity reactions. Poly-${\gamma}$-glutamic acid (PGA) is a biodegradable polymer that is produced by Bacillus subtilis. This study was performed to assess the effects of PGA in a canine model of ACD. ACD was induced on the back of dogs induced by sensitization and repeated application by 2,4-dinitro-1-chlorobenzene (DNCB). Topical treatment of PGA was applied once a day for 12 days and skin biophysical parameters including transepidermal water loss (TEWL), skin hydration, skin pH, skin thickness and erythema index, were measured every two days during experimental periods. Histopathology and immunohistochemistry were performed to evaluate the antiinflammatory effect. In skin biophysical parameters, TEWL, skin hydration, skin thickness and erythema index were significantly increased, with a maximum increase appeared on day 2 (p < 0.05). On the other hand, skin pH was significantly decreased, with a maximum decrease appeared on day 2 (p < 0.01). After the completion of PGA treatment, skin biophysical parameters were significantly reached those of baseline in a time-dependent manner (p < 0.05). In histopathology, marked increases of epidermal thicknesses were induced after DNCB challenge with numerous inflammatory cell infiltrations and edematous changes, decreases of connective tissue occupied regions in dermis. In addition, marked increases of cytokine - tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$)-immunoreactivities in the dermis and of apoptotic markers - caspase-3 and PARP-immunoreactivities in the epidermis were observed in DNCB-PBS control as compared with intact control, respectively (p < 0.01). It means, the ACD and related apoptotic changes were induced by DNCB in the present study. However, these ACD induced by DNCB and related apoptosis in epidermis were significantly inhibited by treatment of PGA treated skin, the decreases of infiltrated inflammatory cells and related decreases of pro-inflammatory cytokine immunoreactivities were also observed (p < 0.01). Based on these findings, PGA may have anti-inflammatory and alleviatory effects in the allergic contact dermatitis.

  • Purpose : We wanted to determine the characteristics of patients with Kawasaki disease (KD) who were unresponsive to intravenous immunoglobulin (IVIG). Methods : The patients with KD were divided into two groups: the IVIG responsive group (25 cases) and the IVIG unresponsive group (14 cases). We analyzed various parameters before and after the administration of IVIG, including the complete blood cell count with the differential count (%), the erythrocyte segmentation rate (ESR), the C-reactive protein (CRP) level and the protein and lipid profiles. Results : The IVIG unresponsive group had a prolonged duration of fever and a higher incidence of CAL compared to the IVIG responsive group (P<0.001, respectively). Before IVIG infusion, the neutrophil differential, the ESR and the CRP values were higher (P<0.001), and the total protein and albumin values were lower in the IVIG unresponsive group (P=0.01) compared to the IVIG responsive group. After IVIG infusion, there were no significant changes in the WBC count and CRP levels in the IVIG unresponsive group. The reduction of the HDL-cholesterol levels by IVIG was more significant in the unresponsive group (P=0.02). Conclusion : A more severe and prolonged inflammatory response occurred in the IVIG unresponsive group at an early stage, and this finding can be detected by such inflammatory parameters as the neutrophil count and the CRP and HDL-cholesterol levels after IVIG infusion.

  • This study aimed to determine whether or not glycoprotein isolated from Cudrania tricuspidata Bureau fruit(CTB glycoprotein) exerts a hepatoprotective effect on liver injury induced by the administration of carbon tetrachloride($CCl_4$, 1.0mL/kg) to A/J mice. Following the administration of CTB glycoprotein(0-20mg/kg), the activities of antioxidant enzymes (superoxide dismutase(SOD), catalase(CAT), and glutathione peroxidase(GPx)), and the quantities of measured thiobarbituric acid reactive substances(TBARS), lactate dehydrogenase(LDH), and nitric oxide(NO) were evaluated from the murine liver tissues and plasma. Additionally, the activity of nuclear factor-kappa B(NF-${\kappa}B$) was assessed after pretreatment with $CCl_4$. When the mice were treated with $CCl_4$ alone, the activities of antioxidative enzymes reduced but amounts of TBARS, LDH, and NO increased. However, the results of treatment with CTB glycoprotein(10 and 20 mg/kg) revealed significantly increased activities of antioxidant enzymes(SOD, CAT, and GPx), as compared with $CCl_4$ alone. On the other hand, the result showed significant diminutions of the quantities of TBARS, LDH, and NO after treatment with CTB glycoprotein(10 and 20 mg/kg), as compared to $CCl_4$ alone. The activity of NF-${\kappa}B$ also declined after pretreatment with CTB glycoprotein, as compared with $CCl_4$ treatment alone. Thus, it is suggested that the CTB glycoprotein exerts a protective effect against $CCl_4$-induced liver injury in A/J mice.

  • Purpose: To investigate the relation of the gastric epithelial cell proliferation, apoptosis and genotypes of H. pylori in children. Methods: Histologic grading by updated Sydney system, PCNA immunostaining, TUNEL method and the genotypes (cagA, picB and iceA) by PCR were performed in H. pylori positive (N=20) and negative (N=20) gastric biopsy specimens. Results: PCNA index was significantly different between H. pylori positive children ($77.4{\pm}13.12$) and H. pylori negative children ($52.3{\pm}12.20$) (p=0.000). There were positive correlations between PCNA index and H. pylori density (r=0.624, p=0.000), polymorphonuclear neutrophil activity (r=0.460, p=0.005) and chronic inflammation (r=0.433, p=0.009). Apoptosis index of H. pylori positive children ($0.70{\pm}0.411$) was significantly higher than of H. pylori negative children ($0.14{\pm}0.201$) (p=0.000). Positive correlations between apoptosis index and H. pylori density (r=0.691, p=0.000), polymorphonuclear neutrophil activity (r=0.585, p=0.000) and chronic inflammation (r=0.535, p=0.001) were noted. As PCNA index increased, apoptosis index significantly increased (r=0.527, p=0.001). The positive rates of genotypes were cagA 90%, picB 75%, iceA1 60% and iceA2 15%, respectively. There were no significant correlations between the status of the genotypes and PCNA index, apoptosis index, the endoscopic findings and the histologic findings. Conclusion: PCNA index and apoptosis index in H. pylori positive children were higher than in H. pylori negative children but were not related to H. pylori genotypes. This study suggested that correlatively increased gastric epithelial cell proliferation and apoptosis are important to pathogenesis of H. pylori infection in children.

  • Purpose : Eosinophil is one of the important inflammatory cell involved in the airway inflammation in childhood asthma. It has been demonstrated that markers of eosinophil activation, including eosinophil cationic protein or eosinophil protein X(EPX), are increased in childhood asthma. Furthermore, they are related to disease activity and are assumed to be helpful in monitoring the treatment effect as urinary EPX(U-EPX) can be obtained easily and in a noninvasive way in children of all ages. Methods : Twenty-five children(22 male and three female) aged $11.87{\pm}3.82$ years with stable asthma were challenged with methacholine and urine was collected from each child during the following periods; before methacholine challenge test(MCT); 0-3 hr after the end of MCT; 4-7 hr after the end of MCT; and 8-24 hr after the end of MCT. Bronchial reactivity was determined by using Dosimeter( Jeager, Germany) with serially diluted methacholine from 0.05 to 25.0 mg. The $FEV_1$ less than 80% of baseline value were classified into positive MCT. U-EPX was measured with a sensitive and specific radioimmunoassay(Pharmacia & Upjohn AB, Uppsala, Sweden). Results were expressed as ${\mu}gEPX/mmol$ creatinine. Results : An early airway response after MCT was associated with an increase of U-EPX excretion for 0-3 hr after methacholine inhalation in comparison with beseline values. Most subjects showed a small increase in U-EPX excretion during late asthmatic response for 4-7 hr, which then decreased to normal level in 8-24 hr. Also, a tendency for a higher increase of U-EPX was associated with a lower threshold of methacholine challenge and a longer duration of asthma. Conclusion : Measurement of EPX in urine is a noninvasive and easy method to assess the severity of airway inflammation in asthmatic children. It may be a helpful index of the events underlying the airway inflammatory responses during nonspecific bronchial challenge, and in monitoring asthma management.

  • The aim of this study was to determine the effects of stocking density and strain on the performance and physiological adaptive responses including the plasma corticosterone content and the level of mRNA expression of pro-inflammatory cytokines and antioxidant enzymes in broiler chicks. A total of 300 birds of two strains (150 Ross strain vs. 150 Cobb strain) aged 3-d old were allotted into two stocking densities (standard stocking density,$0.046m^2/bird$ vs. high stocking density, $0.023m^2/bird$) in battery cages by $2{\times}2$ factorial designs with ten replicates until 35 d of age. There was no significant strain effect on body weight, feed intakes and feed to gain ratio and the relative organ weights. However body weight, feed intakes and relative organ weight were found to be significantly (P<0.05) affected by the effect of stocking density. Plasma corticosterone level was not affected by both stocking density and strain effects. Hepatic mRNA expression of pro-inflammatory cytokines including interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6, IL-18 and interferon-gamma (IFN-${\gamma}$) was not significantly changed by the effects of strain and stocking density. However, the mRNA expression of glutathione peroxidase (GPX) was affected by strain, showing that Ross strain decreased (P<0.05) the GPX expression. With respect to the effect of stocking density, there was a significant (P<0.05) increase in superoxide dismutase (SOD) and catalase (CAT) and GPX mRNA expression in the liver from high stocking density group. Splenic pro-inflammatory cytokine expression was not also affected by stocking density and strain, except that IL-18 mRNA significantly (P<0.05) decreased in Cobb strain under high stocking density. The mRNA expression of SOD and CAT was significantly (P<0.05) affected by the effects of stocking density and strain. In conclusion, growth performance was not affected by strain but stocking density. Although mRNA expression of major pro-inflammatory cytokines was not changed by stocking density and strain, antioxidant enzyme was significantly affected by stocking density, strain or even organ in birds under summer conditions. More detailed studies still needed to be explored to elucidate the effects of environmental conditions and genetic background on physiological responses in birds.

  • Purpose : The aim of this study was to evaluate the effect of inhaled nitric oxide(iNO) on gas exchange, hemodynamics and pulmonary inflammation in newborn piglets with E. coli induced septic lung. Methods : Twenty three instrumented and ventilated piglets were randomized into three groups : CON(n=6), PCON(n=9), and PNO(n=8). In the piglets of the PCON and PNO groups, E. coli septic lung was induced by endotracheal instillation of E. coli. Ten ppm iNO was given continuously in the PNO group after endotracheal instillation of E. coli. All animals were mechanically ventilated for six hour with a peak inspiratory pressure of 30 $cmH_2O$, frequency of 25 breaths/min, $FiO_2$ 1.0 and a positive end-expiratory pressure of 4 $cmH_2O$. All measurements were made at one hour intervals during the experiment. At the end of the experiment, lung tissue was harvested for the analysis of myeloperoxidase activity, indicative of lung inflammation. Results : All piglets with pulmonary instillation of E. coli developed E. coli sepsis. Piglets in the PCON group developed progresseve pulmonry hypertension, hypoxemia and hypercarbia compared to the CON group due to increased pulmonary vascular resistance, intrapulmonary shunt fraction and physiologic dead space fraction. iNO did not reverse pulmonary hypertension in the PNO group. However iNO significantly improved oxygenation, which was attributed to marked improvement of venous admixture and partial attenuation of increase in dead space fraction. Increased myeloperoxidase activity in PCON compared to CON was significantly attenuated in PNO. Conclusion : iNO improves oxygenation and lung inflammation in newborn piglets with E. coli induced septic lung.
