The purposes of this study were to compare and quantify the expression of IL-6, e1stase and ${\alpha}_1-PI$ in the gingival tissues of patients with type 2 diabetes mellitus and healthy adults with chronic periodontitis. Gingival tissue samples were obtained during periodontal surgery or tooth extraction. According to the patient's systemic condition & clinical criteria of gingiva, each gingival sample was devided into three groups. Group 1 (n=8) is clinically healthy gingiva without bleeding and no evidence of bone resorption or periodontal pockets, obtained from systemically healthy 8 patients. Group 2 (n=8) is inflammed gingiva from patients with chronic periodontitis. Group 3 (n=8) is inflammed gingiva from patients with chronic periodontitis associated with type 2 diabetes. Tissue samples were prepared and analyzed by Western blotting. The quantification of IL-6, elastase and ${\alpha}_1-PI$ were performed using a densitometer and statistically analyzed by one-way ANOVA followed by Tukey test. 1. The expression levels of IL-6 showed increasing tendency in group 2 and 3, and It was highest in group 3. 2. The expression of elastase showed increasing tendency in group 2 and 3, and It was highest in group 3. 3. The expression of ${\alpha}_1-PI$ showed increasing tendency in group 3 compared to group 1. 4. The ${\alpha}_1-PI$/elastase ratio was decreased in group 2 and 3 compared to group 1, especially most decreased in group 3. 5. As IL-6 levels were increasing, elastase showed increasing tendency in group 3, and although IL-6 and elastase levels were increasing, ${\alpha}_1-PI$ level in group 3 showed slightly increasing pattern comparing to group 1. In conclusion, this study demonstrated that the expression levels of IL-6 and elastase will be inflammatory markers of periodontal inflammed tissue and DM. The ${\alpha}_1-PI$/elastase ratio also may be important measuring inflmmatory factors in the progression of periodontal inflammation associated to type 2DM.

Background: There are many evidences that inflammation is an important determinant of the development of atherosclerosis and one of the systemic markers of inflammation, C-reactive protein(CRP), is associated with extent of coronary artery disease and risk of coronary events. We assessed the time response of CRP response after coronary angioplasty and it's influence on the clinical restenosis in angina patients. Materials and Methods: Patients included 36 angina patients undergoing single vessel angioplasty. Levels of CRP were measured before and 12, 24, 48, and 72 hours after angioplasty. Clinical restenosis was assessed at 6 months after procedure. Results: Baseline CRP level was $0.30{\pm}0.01$ mg/dL in stable and $0.46{\pm}0.28$ mg/dL in unstable angina patients(p<0.05). After angioplasty, CRP level was increased with peak at 24 hour and persisted to 72 hours after angioplasty. At 24 hour after angioplasty, the magnitude of CRP change was $0.32{\pm}0.31$ mg/dL in stable and $0.79{\pm}0.73$ mg/dL in unstable angina patient(p<0.05). The change of CRP level was not associated with troponin-T after angioplasty. In unstable angina patients, clinical restenosis was developed in 8% of patients with low baseline CRP levels and in 50% of those with high baseline CRP levels more than 0.6 mg/dL(p<0.05). Conclusion: In unstable angina patients, inflammatory response is more increased than stable angina patients, and increased inflammatory response effects on the restenosis after coronary angioplasty.
We have recently discovered that mycelium of Phellinus linteus, popular medical mushrooms in Korea, possess alcohol dehydrogenase and produce alcohol. In the present study, it was examined that the effect of fermented rice wine made by using mycelium of P. linteus (FLMP) on the expression of in-flammation-related proteins in both $HepG_2$ cells and rats. To examine the effect of FLMP on the morphology and expression of inflammatory proteins in $HepG_2$ cells, the cells were incubated with ethanol, and FLMP for 24 hours, and then analyzed by microscopic observation and Western blot and reverse transcription polymerase chain reaction (RT-PCR). While ethanol induced the morphological change accompanied with cell debris formation and scattering on $HepG_2$ cells, FLMP had no effect. The results of Western blot and RT-PCR analyses showed that the level of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-1 and COX-2 was induced by ethanol, however, FLMP inhibited the expression of these proteins and its mRNAs. In the animal model, the value of flutamate oxaloacetate transaminase and glutamate pyruvate transaminase was significantly increased by administration with ethanol. But the group administrated with FLMP showed lower levels on the changes of these markers compared with ethanol-administrated group. Besides, the results of Western blot and RT-PCR analyses showed that the expression of inflammatory proteins such as iNOS, COX-1 and COX-2 was not affected by FLMP administration in rat liver. About histopathological and immunohistochemical observations, inflammatory loci were markedly decreased in the FLMP-administrated rat compared to ethanol-administrated rats and showed weaker COX-2 and iNOS jmmunoreactions. These results suggested that FLMP showed slight changes on the inflammatory proteins expression compared to ethanol and FLMP may be used as a functional alcoholic beverage.

This study investigated the effect of mulberry fruit extract(MFE) on antioxidant and anti-inflammatory activities of middle aged women with rheumatoid factor (RF). Thirty two middle-aged subjects were divided into two groups which were normal middle-aged group (NMG) and abnormal middle-aged group whose serum RF level were > 10 u/mL (AMG). All groups had consumed MFE (100 mL/day) for 4 weeks. Anthropometric measurements, serum inflammatory factors, serum oxidative stress markers analyses were performed at baseline and then at 4 weeks following the study. There were no significant differences in anthropometric measurements, including BMI, WHR and body fat composition between two groups. But after 4 weeks MFE consumption, serum levels of C-reactive protein (CRP), ferric-reducing ability of plasma (FRAP), serum TNF-${\alpha}$, IL-2, IL-4 had significantly decreased (p<0.05) in AMG. These findings suggested that the MFE consumption as food may be protective against oxidation and inflammation like RA.

Background: The main factors associated with weight loss in patients with COPD are not well known. Since chronic inflammation and oxidative stress play a major pathogenic role in COPD, these factors may be responsible for the patients' weight loss. Therefore, this study measured the body mass index (BMI) in COPD patients and evaluated the variables, such as systemic inflammatory marker, oxidative stress and lung function, that correlate with the BMI. Method: The stable COPD patients (M:F=49:4, mean age=$68.25{\pm}6.32$) were divided into the lower (<18.5), normal (18.5-25) and higher (>25) BMI group. The severity of the airway obstruction was evaluated by measuring the $FEV_1$. The serum IL-6 and TNF-$\alpha$ levels were measured to determine the degree of systemic inflammation, and the carbonyl protein and 8-iso-prostaglandin $F_2{\alpha}$ level was measured to determine the level of oxidative stress. Each value in the COPD patients and normal control was compared with the BMI. Results: 1) Serum 8-iso-prostaglandin $F_2{\alpha}$ in COPD patients was significantly higher ($456.08{\pm}574.12pg/ml$) than that in normal control ($264.74{\pm}143.15pg/ml$) (p<0.05). However, there were no significant differences in the serum IL-6, TNF-$\alpha$, carbonyl protein between the COPD patients and normal controls. 2). In the COPD patients, the $FEV_1$ of the lower BMI group was significantly lower ($0.93{\pm}0.25L$) than that of the normal BMI ($1.34{\pm}0.52L$) and higher BMI groups ($1.72{\pm}0.41L$) (p<0.05). The lower $FEV_1$ was significantly associated with a lower BMI in COPD patients (p=0.002, r=0.42). The BMI of very severe COPD patients was significantly lower ($19.8{\pm}2.57$) than that of the patients with moderate COPD ($22.6{\pm}3.14$) (p<0.05). 3). There were no significant differences in the serum IL-6, TNF-$\alpha$, carbonyl protein and 8-iso-prostaglandin $F_2{\alpha}$ according to the BMI in the COPD patients. Conclusion: The severity of the airway obstruction, not the systemic inflammatory markers and oxidative stress, might be associated with the BMI in stable COPD patients. Further study will be needed to determine the factors associated with the decrease in the BMI of COPD patients.
Background : It is known that airway inflammation is present in most patients with asthma, but the relationship between symptoms and the severity and nature of airway inflammation has not been established. Cough variant asthma is defined as an asthma in which the dominant symptom is cough, and the condition can be successfully treated with inhaled steroids. This study was performed to evaluate the time course of bronchial responsiveness according to an inhaled anti-inflammatory therapy and the factors which affect the resolution of bronchial responsiveness, and an efficacy of nedocromil to cough asthma. Method: A prospective study for the investigation of bronchial responsiveness according to an inhaled anti-inflammatory treatment in sixty-one cough asthmatics was performed. Twenty-three entered budesonide ($400{\mu}g{\times}2/day$), twenty-two entered nedocromil ($4mg{\times}2/day$) and sixteen patients entered combined group. The bronchial hyperresponsiveness (BHR) was estimated by methacholine challenge test using counted breath method. The symptom was estimated by 'symptom score'. Reevaluation of BHR and symptom was performed at 2 month after treatment, and if BHR was not resoluted at this time, regarded as a non-responder, and then follow-up of BHR and symptom was performed at 4- and/or 6 month after treatment. Results: The improvement of BHR and symptom was significant in 2 month (p<0.05), but there was no change of them during follow-up period of 4- and/or 6 month in non-responders. In comparison of allergic markers such as serum total IgE, peripheral eosinophil count and skin test reactivity between responders and non-responders, there was no difference in each other. However, in comparison of other factors such as cumulative pack-years, symptom duration, age, gender, and the initial degree of PC20, there was a significant difference in each other(p<0.05). The percent of patients with the resolution of BHR in 2 month was not different in each group(p=0.95). There was no significant difference in the degree of improvement of BHR and symptom in each group. Conclusion: Bronchial responsiveness and symptom was not significantly improved in non-responders during follow-up period of 4- and/or 6 month. The effect of inhaled nedocromil was equivalent to that of inhaled steroid in cough asthmatics, and the response to combined treatment is not superior to that achieved by either of these agents used alone.
Background : As the pleural inflammation progresses, exudative pleural fluid becomes loculated rapidly with pleural thickening. Complete drainage is important to prevent pleural fibrosis, entrapment and depression of lung function. Intrapleural urokinase instillation therapy has been advocated as a method to facilitate drainage of gelatinous pleural fluid and to allow enzymatic debriment of pleural surface. This study was designed to investigate the predictors of effectiveness of intrapleural urokinase in the treatment of loculated pleural effusion. Method : Thirty-five patients received a single radiographically guided pig-tail catheter ranging in size from 10 to 12 French. Twenty-two patients had tuberculous pleural effusions, and 13 had non-tuberculous postpneumonic empyemas. A total of 240,000 units of urokinase was dissolved in 240 ml of normal saline and the aliquots of 80mL was instilled into the pleural cavity via pig-tail catheter per every 8hr. Effectiveness of intrapleural urokinase instillation therapy was assessed by biochemical markers, ultrasonography, and technical details. A greater than 50% improvement on follow-up chest radiographs was defined as success group. Result : Twenty-seven of 35 (77.1%) patients had successful outcome to urokinase instillation therapy. Duration of symptoms before admission was shorter in success group ($11.8{\pm}6.9day$) than in failure group ($26.62{\pm}16.5day$) (P<0.05). Amount of drained fluid during urokinase therapy was larger in success group ($917.1{\pm}392.7ml$) than in failure group ($613.8{\pm}259.7ml$) (P<0.05). Pleural fluid glucose was higher in success group ($89.7{\pm}35.9mg/dl$) than in failure group ($41.2{\pm}47.1mg/dl$) (P<0.05). Pleural fluid LDH was lower in success group ($878.4{\pm}654.3IU/L$) than in failure group ($2711.1{\pm}973.1IU/L$) (P<0.05). Honeycomb septated pattern on chest ultrasonography was observed in six of eight failure group, but none of success group (P<0.05). Conclusion : Longer duration of symptoms before admission, smaller amount of drained fluid during urokinase therapy, lower glucose value, higher LDH value in pleural fluid examination, and honeycomb septation pattern on chest ultrasonograph were predictors for failure group of intrapleural urokinase instillation therapy.

Objectives : The purpose of this study is to determine whether there is a significant difference in the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio according to the history of suicide attempt in patients with psychiatric diseases. Methods : A medical record review was conducted on patients who had been hospitalized in Konyang University Hospital since 2021-03-01 to 2023-02-28 to collect demographic and clinical characteristics. T-test for continuous variables and Chi-square test for categorical variables were performed to determine demographic differences according to the history of suicide attempt, and the ANCOVA test was performed to compare the average value of peripheral inflammatory marker according to the history of suicide attempt with gender and age as covariates. One-way variance analysis was performed to determine whether the number of suicide attempt causes significant difference of the peripheral inflammatory marker. Results : The final analysis target of this study was 266 patients, 101 had history of suicide attempt, and 165 had no history of suicide attempt. The neutrophil-to-lymphocyte ratio (p<0.001) and platelet-to-lymphocyte ratio (p<0.001) were higher in patients with the history of suicide attempt than patients without the history of suicide attempt, but the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were not significantly increased depending on the serial increase of number of suicide attempts. Conclusions : This study suggests that peripheral inflammatory markers are meaningful and easily accessible indicators for predicting the risk of suicide attempt in psychiatric patients. We expect that prospective follow-up study will be conducted with more subjects and controlled potential confounding variables.

It was confirmed that complex fermentation (CF) was more efficient than single-strain fermentations in inducing changes in the contents of phenolic compounds of Maclura tricuspidate and Pyrus Montana Nakai. A mixture of Maclura tricuspidata, Pyrus montana Nakai, Platycodon grandiflorum and Codonopsis lanceolata were fermented in CF using Aspergillus shirousamii (koji), yeast, and lactic acid bacteria (LAB) for 24 days, and the pH, °Brix, total acidity, anti-oxidant activity, polyphenol content, nitric oxide (NO), and Western blotting of inducible nitric oxide synthase (iNOS), cyclo-oxygenase-2 (COX-2), and tumor necrosis factor-𝛼 (TNF-𝛼) of the sample were determined. There was no significant change in pH and total acidity. °Brix significantly decreased from day 6 onwards. HPLC confirmed that the concentrations of chlorogenic acid, 4-hydrobenzoic acid, vanillic acid, and caffeic acid significantly increased from day 18 during the fermentation. Additionally, DPPH, ABTS radical scavenging activity, total phenol, and total flavonoid were confirmed to be increased until 18 days. NO was significantly inhibited from day 6, along with significant inhibition of iNOS, COX-2, and TNF-a. In conclusion, this study confirmed that CF of low-use (or underutilized) wild vegetables enhances phenolic compounds. It effectively suppresses NO, iNOS, COX-2, and TNF-𝛼, markers of inflammation-related pathogenesis. Altogether, our results suggest that CF of the above plants has a potential anti-inflammatory effect.
