Background: The dysfunction of multiple organs is found to be caused by reactive oxygen species as a major modulator of microvascular injury after hemorrhagic shock. Hemorrhagic shock, one of many causes inducing acute lung injury, is associated with increase in alveolocapillary permeability and characterized by edema, neutrophil infiltration, and hemorrhage in the interstitial and alveolar space. Aggressive and rapid fluid resuscitation potentially might increased the risk of pulmonary dysfunction by the interstitial edema. Therefore, in order to improve the pulmonary dysfunction induced by hemorrhagic shock, the present study was attempted to investigate how to reduce the inflammatory responses and edema in lung. Material and Method: Male Sprague-Dawley rats, weight 300 to 350 gm were anesthetized with ketamine(7 mg/kg) intramuscular Hemorrhagic Shock(HS) was induced by withdrawal of 3 mL/100 g over 10 min. through right jugular vein. Mean arterial pressure was then maintained at $35{\sim}40$ mmHg by further blood withdrawal. At 60 min. after HS, the shed blood and Ringer's solution or 5% albumin was infused to restore mean carotid arterial pressure over 80 mmHg. Rats were divided into three groups according to rectal temperature level($37^{\circ}C$[normothermia] vs $33^{\circ}C$[mild hypothermia]) and resuscitation fluid(lactate Ringer's solution vs 5% albumin solution). Group I consisted of rats with the normothermia and lactate Ringer's solution infusion. Group II consisted of rats with the systemic hypothermia and lactate Ringer's solution infusion. Group III consisted of rats with the systemic hypothermia and 5% albumin solution infusion. Hemodynamic parameters(heart rate, mean carotid arterial pressure), metabolism, and pulmonary tissue damage were observed for 4 hours. Result: In all experimental groups including 6 rats in group I, totally 26 rats were alive in 3rd stage. However, bleeding volume of group I in first stage was $3.2{\pm}0.5$ mL/100 g less than those of group II($3.9{\pm}0.8$ mL/100 g) and group III($4.1{\pm}0.7$ mL/100 g). Fluid volume infused in 2nd stage was $28.6{\pm}6.0$ mL(group I), $20.6{\pm}4.0$ mL(group II) and $14.7{\pm}2.7$ mL(group III), retrospectively in which there was statistically a significance between all groups(p<0.05). Plasma potassium level was markedly elevated in comparison with other groups(II and III), whereas glucose level was obviously reduced in 2nd stage of group I. Level of interleukine-8 in group I was obviously higher than that of group II or III(p<0.05). They were $1.834{\pm}437$ pg/mL(group I), $1,006{\pm}532$ pg/mL(group II), and $764{\pm}302$ pg/mL(group III), retrospectively. In histologic score, the score of group III($1.6{\pm}0.6$) was significantly lower than that of group I($2.8{\pm}1.2$)(p<0.05). Conclusion: In pressure-controlled hemorrhagic shock model, it is suggested that hypothermia might inhibit the direct damage of ischemic tissue through reduction of basic metabolic rate in shock state compared to normothermia. It seems that hypothermia should be benefit to recovery pulmonary function by reducing replaced fluid volume, inhibiting anti-inflammatory agent(IL-8) and leukocyte infiltration in state of ischemia-reperfusion injury. However, if is considered that other changes in pulmonary damage and inflammatory responses might induce by not only kinds of fluid solutions but also hypothermia, and that the detailed evaluation should be study.
Background : The cell-mediated immune response plays an important role in tuberculosis. After being activated by mycobacterial antigens, T lymphocytes express a high affinity receptor (IL-2R) for interleukin-2 (IL-2) on their own surface and release a soluble fraction of the IL-2 receptor (sIL-2R) from the cell membrane into the circulation. Neopterin is a metabolite of guanosine-triphosphate, which is produced by stimulated macrophages under the influence of IFN-$\gamma$ with a T lymphocyte origin. Therefore, the utility of sIL-2R, IFN-$\gamma$ and the neopterin levels as immunologic indices of the cell-mediated immune response and severity of disease in patients with pulmonary tuberculosis was assessed. Methods : The serum sIL-2R, IFN-$\gamma$ and neopterin levels were measured in 39 patients with pulmonary tuberculosis, 6 patients with tuberculous lymphadenitis prior to treatment and 10 healthy subjects. The serum and pleural sIL-2R, neopterin and ADA levels were measured in 22 patients with tuberculous pleurisy. The patients with pulmonary tuberculosis were divided into a mild, moderate and severe group according to the severity by ATS guidelines. To compare the results from these patients with those of the pretreatment levels, the sIL-2R, IFN-$\gamma$ and neopterin levels were measured in 36 of the 39 patients(1 patient, expired; 2 patients were referred to a sanitarium) with pulmonary tuberculosis after 2 months of treatment. Results : 1) the serum sIL-2R and IFN-$\gamma$ levels were elevated in patients with tuberculosis when compared to those of healthy subjects (p>0.05). The neopterin concentration in the serum was significantly lower in patients with pulmonary tuberculosis($2967{\pm}2132.8$ pg/ml) than in healthy controls($4949{\pm}1242.1$ pg/ml)(p<0.05). 2) In the pulmonary tuberculosis group, the serum sIL-2R and IFN-$\gamma$ levels were higher in patients with severe disease than those in patients with mild and moderate disease. However, the neopterin levels declined as the pulmonary tuberculosis became more severe (p<0.01). 3) The mean serum sIL-2R and IFN-$\gamma$ levels declined from $1071{\pm}1139.4$ U/ml to $1023{\pm}1920.9$ U/ml(p>0.05), $41{\pm}52.8$ pg/ml to $22{\pm}23.9$ gm/ml(p<0.05), respectively, after 2 month of treatment. The mean serum neopterin levels increased from $3158{\pm}2272.6$ pg/ml to $3737{\pm}2307.5$ pg/ml(p>0.05) after a 2 month of treatment. These findings were remarkable in the severe group of pulmonary tuberculosis with a clinical correlation. 4) In the patients with tuberculous pleurisy, the serum sIL-2R and ADA were significantly higher than those in the pleural fluid, However, the neopterin levels in the sera and pleural effusion were similar. Conclusion : On the basis of this study, sIL-2R, IFN-$\gamma$ and neopterin measurements may not only provide an insight into the present state of the cell-mediated immune response, but also serve as parameters monitoring of the prognosis of the disease, particularly in patients with severe pulmonary tuberculosis. In addition, an assay of the pleural sIL-2R levels might signal a stimulated local immunity including T cell activation in the tuberculous pleural effusion.
Objectives : Ojeok-san, a traditional herbal formula, has been used for the treatment of cold illness and its related symptoms such as headache, nausea and indigestion. This study was performed to compare effects of water (OJSW) and 70% ethanol extracts (OJSE) of Ojeok-san on inflammation and its related diseases atopy, asthma and obesity in vitro. Methods : We performed HPLC to investigate contents of index components of OJSW and OJSE. We investigated the effects of OJSW and OJSE with an in vitro model, using 5 cell lines, specifically RAW 264. 7, HaCaT, MC/9, BEAS-2B and 3T3-L1. Results : HPLC analysis displayed that the contents of index components were higher in OJSE than OJSW. In lipopolysaccharide (LPS)-treated RAW 264.7 macrophages, OJSE significantly inhibited productions of interleukin (IL)-6, nitrite and prostaglandin $E_2$ ($PEG_2$). In TNF-${\alpha}$/IFN-${\gamma}$-treated HaCaT keratinocytes, OJSE significantly lowered levels of macrophage-derived chemokine (MDC) as well as regulated and normal T cell expressed and secreted (RANTES). OJSE also had a protective effect on inflammatory response by decreasing RANTES secretion in TNF-${\alpha}$-stimulated BEAS-2B cells. Conclusions : We conclude that OJSE could be more appropriate to enhance the biological activities against inflammation and its related diseases, and could be applied as a bioactive material for developing the potent anti-inflammatory agents.
In this study, we established a radiodermatitis animal model and investigated the change in immune cell proportions in the secondary lymphoid organs. The cells responsible for the increased transforming growth factor-${\beta}1$ (TGF-${\beta}1$) and interleukin-10 (IL-10) production in the lesions following irradiation were also investigated. The radiodermatitis model was constructed by locally exposing the posterior dorsal region of hairless-1 (HR-1) mice to 10 Gy electron (E)-ray/day for six consecutive days. The change in immune cell proportions was analyzed by FACS. Immunohistochemistry was carried out to detect the expression of cytokines and cell-specific markers in the skin. The proportions of antigen-presenting cells, T cells, and B cells in the lymph nodes and spleen were affected by E-irradiation. After irradiation, TGF-${\beta}1$ and IL-17 were co-localized in the papillary region of the dermis with keratin-14 (K-14)-positive cells rather than with regulatory T cells (Treg). IL-10 was not co-stained with Treg, T helper 17 (Th17) cells, dendritic cells, or macrophages. Our data indicate that TGF-${\beta}1$ is over-expressed mainly by proliferated keratinocytes in the lesions of a radiodermatitis animal model.

An experiment was conducted to investigate the effect of fermented garlic solution (FGS) on the performance, egg quality and blood profiles of laying hens in the finishing period. In total, 432 Lohmann Brown hens aged 79 weeks were equally distributed into four dietary treatments with six replicate. Hens were fed the basal diet containing 2,750 kcal/kg of ME and 16% of CP, which was supplemented with either 0% (control), 0.05%, 0.10% and 0.20% FGS from 79 to 83 weeks old. Laying performance, egg quality, yolk fatty acids and serum characteristics were analyzed at the end of experiment. Egg production and feed conversion was numerically improved in FGS supplementation treatments compared to those in the control, but were not statistically different. The albumen height and Haugh unit showed significant increase (P<0.05) in the FGS supplementation groups. The concentration of saturated fatty acid decreased in the yolks of birds fed FGS (P<0.01), whereas the unsaturated fatty acid (UFA) and mono-UFA contents were significantly higher (P<0.01) in those treatments than in the control. Significantly lower natural fat and cholesterol in serum were observed in birds fed the 0.20% FGS supplementation diet (P<0.01). However, the high-density lipoprotein (HDL) cholesterol increased in both the 0.10% and 0.20% FGS supplementation groups. In addition, interleukin-2 mRNA and CD4+/CD8+ level in serum which were cellular immunity indicators showed statistical differences (P<0.01) among treatments and a higher concentration in the 0.10% and 0.20% FGS groups than in the control. Thus, it can be concluded that dietary supplementation of FGS improved egg quality and stimulated immune response in mature laying hens.

Natural killer cell activity was insignificant for S-180 cell treated with Triglii semen Herbal acupuncture.(p<0.05) 10. lnterieukin-2 productivity was decreased for S-180 cell treated with Triglii semen Herbal acupuncture compared to the normal and control group.(p<0.05) Conclusion: According to the results, we can conclude Herbal-acupuncture with Triglii semen caused toxicity, and caused no effects in S-180 cancer cell.
Purpose: The aim of this study was to clarify the serum cytokine pattern in patients with chronic HBV infection in terms of their clinical state. Methods: Intravenous blood samples were taken from 35 patients who were seropositive for HBsAg for at least 6 months and 7 healthy controls. Samples were initially tested for serum aminotransferases and serologic markers for hepatitis B virus by EIA. Serum levels of interleukin(IL)-2, tumor necrosis factor-alpha (TNF-${\alpha}$), interferon-gamma (IFN-${\gamma}$), IL-4, and IL-10 were measured by ELISA. Results: Among 35 patients, seropositive for HBeAg was 20 and for anti-HBe was 15. The histologic diagnosis of 19 patients underwent liver biopsy were chronic persistent hepatitis (CPH) in 10 and chronic active hepatitis (CAH) in 9. Serum IL-10 level in patients seropositive for HBeAg was significantly higher than that in patients seropositive for anti-HBe (p<0.05). All measured cytokine levels in patients with CAH were higher than those of patients with CPH. High values of all measured cytokines except IL-4 were seen in patients with AST and ALT > 100 U/L. High level of IL-4 was seen in patients with normal aminotransferase levels. Conclusion: These results were thought to indicate that anti-inflammatory Th2-like cytokine (IL-10) production in chronic HBV infection is related to circulating HBeAg rather than activity of hepatitis and that Th1 cytokines seem to be associated with the increasing activity of hepatitis.

This study was conducted to investigate the effect of dietary silicate based complex mineral (SCM) on the performance of broiler chicks. Four hundred fifty one day old Cobb ${\times}$ Cobb broiler chicks were fed with commercial diets at 0%, 0.05%, 0.10%, 0.15% and 0.20% SCM with five replicates for five weeks. Weight gain, feed intake and feed conversion were measured weekly, and blood composition, immunity and meat quality were evaluated at the end of experiment. During overall period weight gain in chicks fed diet containing 0.1% SCM was significantly increased as compared with that of control (p<0.05). Feed intake showed no consistency among the treatments. Feed conversion appeared to increase in the chickens fed with SCM addition diets during prestarter period. Albumin, glucose and other blood parameters related to chicken health tended to improve at the level of 0.05% SCM addition treatments. Drip loss in breast meat was significantly decreased in more than 0.05% SCM addition (p<0.05). The expression of IL-2 (Interleukin-2) in blood increased significantly in the chickens fed with SCM of 0.05% or 0.10% level than other treatments (p<0.05). The optimum SCM concentration for commercial dietary supplementation for improving broiler performance and other health-related parameters was 0.10%.

This study investigated the effect of the dichloromethane fraction form Katsuwonus pelamis heart on anti-inflammatory responses in lipopolysaccharide-stimulated RAW 264.7 cells and mouse models. Ethanol extract was partitioned with dichloromethane, ethyl acetate, butanol, and water. Among the fractions, the dichloromethane fraction showed a significant decrease in nitric oxide (NO) and pro-inflammatory cytokines [interleukin (IL)-6, $IL-1{\beta}$, and tumor necrosis $factor-{\alpha}$] production compared to ethanol extract. The dichloromethane fraction attenuated the expression of inducible nitric oxide synthase and nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) p65 proteins in a dose-dependent manner. In addition, the expression of phosphorylation of mitogen-activated protein kinases (MAPKs) was also inhibited by the dichloromethane fraction. Moreover, the administration of 10, 50, and 250 mg/kg body weight-dose dependently inhibited the formation of edema by croton-oil and the application of dichloromethane (2 mg/ear) significantly reduced epidermal and dermal thickness and the infiltrated mast cell numbers. Therefore, the dichloromethane fraction exhibited an anti-inflammation effect by inhibiting $NF-{\kappa}B$ and MAPK signaling activation in macrophages.

Background : The heat shock protein (HSP) 70 families are known to protect cells against the irreversible tissue injury induced by stress and to induce the recovery of cell function during stress. Heat pretreatment was reported to decrease the acute lung injury (ALI) of rats induced by lipopolysaccharide (LPS). However, the role of heat shock with LPS co-treatmenton ALI is unclear. The purpose of this study was to investigate the effect of heat treatment, which was given immediately after the beginning of ALI induced by LPS intratracheally administered in rats. Methods : Either saline (saline group) or LPS was intratracheally instilled without heat treatment (LPS group). In addition, heat was conducted 18 hours prior to the instillation of LPS (pre-treatment group) and conducted immediately after instillation of LPS (co-treatment group). Six hours after the LPS or saline treatment, blood, bronchoalveolar lavage (BAL) fluid and lung tissue samples were obtained. The myeloperoxidase (MPO) activity and the heat shock protein expression in the lung tissue, the differential counts of the polymorphonuclear leukocytes (PMN) in the BAL fluids, and the LDH, protein, $IL-1{\beta}$, $TNF-{\alpha}$ and IL-10 levels in BAL fluid and serum were measured. Results : 1) The MPO activity, the differential PMN counts in the BAL fluid, BAL fluid and serum cytokines were higher in the LPS, the heat pre-treatment and co-treatment group than those of the saline group (p value <0.05). 2) The MPO activity and the protein level in the BAL fluid from the heat co-treatment group were similar to those of the LPS group. 3) The serum $TNF-{\alpha}$ level of the heat co-treatment group was significantly higher than that of the LPS group (p=0.01). Conclusion : Heat shock response administered immediately after a LPS instillation did not attenuate the ALI in this model.
