  • Hypertension caused by high-fat and high-salt diets is is a well-known significant risk factor for cardiovascular and cerebrovascular diseases. In this study, to confirm the relationship between hypertension and immune cells, angiotensin (Ang) II was administered to Dahl salt-sensitive (SS) rats and Dahl salt-resistant (SR) rats. Then the expression of immune cells and the proinflammatory cytokines were compared between the SS and SR rats. It was observed that after administration of Ang II (50ng/kg/min) for three weeks, blood pressure was increased in the SS rats, but there was no significant change in the SR rats. In addition, the expression of T helper (Th) cells and Th 17 cells in the spleen and the expression of Th cell Rorγt and regulatory T regulatory (Treg) cells in the peripheral blood mononuclear cells did not show a significant difference between the two experimental groups even after the administration of Ang II.IL-1β expression was significantly increased in the kidney tissue of the SS rats, while there was no significant difference in the IL-6 expression in all the experimental groups. The results of this study suggest that Ang II induces hypertension by stimulating IL-1β secretion from renal macrophage in SS rats.

  • Objective: The aim of present study was to assess the anti-oxidant potential of water-soluble peptides (WSPs) extract derived from buffalo and cow milk Cheddar cheeses at different stages of ripening. Methods: The antioxidant potential of WSPs extract was assessed through 2,2'-azinobis-3-ethylbenzothiazoline-6sulfonic acid (ABTS)-radical scavenging activity. In addition, impact of WSPs extract on cell viability and production of reactive oxygen species (ROS) in human colon adenocarcinoma Caco-2 (tert-butylhydroperoxide-induced) cell lines was also evaluated. Results: The ABTS-radical scavenging activity increased progressively with ripening period and dose-dependently in both cheeses. However, peptide extract from buffalo milk Cheddar cheese demonstrated relatively higher activity due to higher contents of water-soluble nitrogen. Intracellular ROS production in Caco-2 cells decreased significantly (p<0.05) till 150th day of cheese ripening and remained constant thereafter. Additionally, dose-dependent response of WSPs extract on antioxidant activity was noticed in the Caco-2 cell line. Conclusion: On the basis of current in vitro study, the Cheddar cheese WSPs extract can protect intestinal epithelium against oxidative stress due to their antioxidant activity.

  • 8-10 week old ICR mice were infected intracerebrally and intraperitoneally with different encephalomyocarditis virus(K$_3$, $K_{11}$, ATT-VR 129) to observe histopathological and immunohistochemical change. Results obtained throuh the experiments were summarized as follows : 1. No differences in clinical signs by the virus strains and the inoculation routes were found. Mice infected with EMCV showed clinical signs after 3 days of inoculation. Main clinical signs were tremors, convulsions, circling movement, and uni or bilateral hindleg paralysis followed by death on the 3-8 days. In general, most of the infected animals died or recovered closely on the 8th day of postinoculation. 2. At necropsy, petechial and ecchymotic hemorrhages in lung were observed and no specific findings in other were observed. 3. In histopathological observation, neuroal cell degeneration perivascular mononucear cell in-filtration gliosis were appeared in central nervous system. Myocarditis with myocardial degeneration and necrosis, calcification were observed along with acinar cell necrosis of exocrine glands in pancreas, severe glomerulonephritis in kidney. Also, focal necrosis of hepatocytes and interstitial pneymonia hyperemia, hemorrhages in lungs were observed. 4. By immunohistochemical staining using ABCIT method, the positive cells were recognized in intracytoplasm of acinar cell in pancreas and intracytoplasm of neuronal cells in cerebrum.

  • The purpose of this study was to evaluate pancreatic ${\beta}$-cell function of Korean adult and to examine the associations between ${\beta}$-cell function and nutrient intakes. Data were analyzed for 1,917 male and 2,885 female subjects older than 30 years using 'The Forth Korean National Health and Nutrition Survey in 2009'. We calculated HOMA ${\beta}$-cell (The homeostasis model assessment of ${\beta}$-cell function) using fasting glucose and fasting insulin for assessing ${\beta}$-cell function. Subjects were divided into HHG (High HOMA ${\beta}$-cell Group) or LHG (Low HOMA ${\beta}$-cell Group) according to median of HOMA ${\beta}$-cell, and then nutrient intakes were compared between two groups. In the entire study population, HHG showed lower percent of carbohydrate intakes (p < 0.05), and higher fat (p < 0.01), percent of fat (p < 0.05), vitamin A (p < 0.05), carotene (p < 0.05) and riboflavin (p < 0.05) intakes than LHG. In addition, levels of HOMA ${\beta}$-cell were negatively correlated with percent of carbohydrate (${\beta}$ = -0.040, p < 0.05), and positively correlated with percent of fat (${\beta}$ = 0.046, p < 0.01). The subjects were then divided into two subgroups according to body mass index values, either $23kg/m^2$ (under- and normal-weight) or ${\geq}23kg/m^2$ (over-weight and obese). Significant differences of some nutrients intakes and correlations with HOMA ${\beta}$-cell were observed only in under- and normal weight subjects, but not in over-weight and obese subjects. In conclusion, high carbohydrate, lower fat and lower vitamin intakes may be related with pancreatic ${\beta}$-cell dysfunction in under- and normal-weight Korean.

  • Objectives : To clarify the possible effects of Sinapis Semen and Raphani Semen on the development of pulmonary eosinophilic inflammation in a asthmatic mouse model. Methods : BALBav/c mice were sensitized to OVA followed intratracheally and by aerosol allergene challenges. We investigated the effect of Sinapis Semen and Raphani Semen on airway hyperresponsiveness, eosinophiic infitratio, immune cell phenotype, The2 cytokine product, and OVA-spedific IgE production. Results : Total lung cells, eosinophils, and lung leukocytes, OVA specific IgE levels, and Th 2cytokine levels such as IL-5, IL-13, IL-17, TNF-alpha, and eotaxin in BALF were reduced compared with those of OVA sensitized asthma mice (control). The absolute numbers of $CD3^+$, $CD3^+/CD69^+$, $CD3^-/CCR3^+$, $CD4^+$, $CD8^+$, $Gr-1^+/CD11b^+$, $B220^+/CD22^+$, $B220^+/IgE^+$ cells in lung tissiues significantly reduced compared to those of control. Specially total lung cells in BALF and the absolute number of $CD3^+/CD69^+$ and, $B220^+/IgE^+$ cells in lung tissiue effectively reduced in Sinapis Semen plus Raphani Semen compared to those of Sinapis Semen and Raphani Semen. Conclusions : These results indicate that Sinapis Semen plus Raphani Semen has deep inhibitory effects on airway inflammation and hyperresponsiveness in asmatic mouse model and also has effect of suppression of IL-5, IL-13, IL-17, OVA specific IgE production in BALF. The results verified that Sinapis Semen, Raphani Semen, and Sinapis Semen plus Raphani Semen could act as a immunomodulator which possess anti-inflammatory and anti-asthmatic property by modulating the relationship of Th1/Th2 cytokine imbalance.

  • Objectives: To retrospectively review the safety and clinical efficacy of bevacizumab concomitant with chemotherapy in Chinese patients with advanced non-squamous non-small cell lung cancer (NSNSCLC). Methods: Clinical data for 79 patients with NSNSCLC who received bevacizumab concomitant with chemotherapy in Chinese PLA General Hospital from April 28th 2009 to May 5th 2013 were retrospectively reviewed to analyze the clinical efficacy including disease control rate (DCR), overall response rate (ORR), progression-free survival (PFS), overall survival (OS), the Eastern Cooperative Oncology Group (ECOG) score and the safety. Results: The Eastern Cooperative Oncology Group (ECOG) score was 0-2. By the final cutoff date (June 9, 2013), 54 (68.4%) patients had disease progression and 37 (46.8%) died. The ORR was 32.9% and the DCR was 83.5%. The ORR of the first-, second-, and third- or later-line treatments were 51.4%, 25.0% and 12.5%, while the DCR were 94.3%, 80.0% and 70.8%, respectively. The median OS (mOS) and PFS (mPFS) were 13.5 and 5.83 months, respectively. The mOS of patients with the first-, second-, and third- or later- line treatments were 16.2, 10.9 and 8.30 months, while the mPFS were 7.27, 5.90 and 5.17 months, respectively. Chemotherapy-related adverse events included myelosuppression, vomiting, hepatic dysfunction and renal dysfunction, while the common serious bevacizumab-related adverse events were thromboembolic problems, gastrointestinal perforation and reversible posterior leukoencephalopathy syndrome, which could be well managed. Conclusions: Bevacizumab concomitant with chemotherapy is effective and the related toxicity can be well tolerated in Chinese patients with NSNSCLC.

  • Background: The purposes of this study were to evaluate the appropriateness of the stage migration of stage IIA non-small cell lung cancer (NSCLC) in the seventh edition of the tumor, node, and metastasis classification for lung cancer to stage IIB lung cancer in the eighth edition, and to identify prognostic factors in patients with eighth-edition stage IIB disease. Methods: Patients with eighth-edition stage IIB disease were subclassified into those with seventh-edition stage IIA disease and those with seventh-edition stage IIB disease, and their recurrence-free survival and disease-specific survival rates were compared. Risk factors for recurrence after curative resection were identified in all included patients. Results: Of 122 patients with eighth-edition stage IIB NSCLC, 101 (82.8%) had seventh-edition stage IIA disease and 21 (17.2%) had seventh-edition stage IIB disease. Nonsignificant differences were observed in the 5-year recurrence-free survival rate and the 5-year disease-specific survival rate between the patients with seventh-edition stage IIA disease and those with seventh-edition stage IIB disease. Visceral pleural invasion was a significant risk factor for recurrence in patients with eighth-edition stage IIB NSCLC. Conclusion: The stage migration from seventh-edition stage IIA NSCLC to eighth-edition stage IIB NSCLC was appropriate in terms of oncological outcomes. Visceral pleural invasion was the only prognostic factor in patients with eighth-edition stage IIB NSCLC.
