Objective: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-${\alpha}$ in the peritoneal fluid of women with and without endometriosis and infertile women. Methods: This study is prospective and case-control study in University hospital, enrolled thirty-four women with laparoscopic findings of minimal to severe endometriosis, and thirty-seven women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. IL-6 and tumor necrosis factor-${\alpha}$ levels in peritoneal fluid were determined using commercial ELISA. IL-6 and tumor necrosis factor-${\alpha}$ concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. Results: IL-6 and tumor necrosis factor-${\alpha}$ concentrations were higher than in the peritoneal fluid of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in peritoneal fluid from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. The concentrations were higher than among of infertile women than in fertile women. A significant correlation between IL-6 and tumor necrosis factor-${\alpha}$ concentrations and endometriosis stage III and IV was noted. Conclusion: Increased levels of IL-6 and tumor necrosis factor-${\alpha}$ in patients with endometriosis in the peritoneal fluid may be relate to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

Background: Cardiopulmonary bypass is an essential process to maintain circulation for saving life during the cardiac surgery, But it is a process in which systemic inflammation was evoked inevitably because of the exposure of blood to foreign surface. The injuries to distal organs during the cardiopulmonary bypass were resulted from systemic inflammation and the disturbances of micro-circulations in the organs. We designed this study to research the effects of leukocyte depletion from pump-oxygenator priming solution on the systemic inflammation, and the micro-circulation of gastric mucosa that is suggested by the gastric mucosal $CO_{2}$ partial pressure and acidity. Material and Method: The dogs were divided into three groups according to the different pump-oxygenator priming solutions; non-hemic crystalloid solution; leukocyte-depleted homologous blood; and non leukocyte-depleted homo-logous blood. Each priming solution group contained five dogs. In all three groups, 2 hours of cardiopulmonary bypass, and 4 consecutive hours of general anesthesia was maintained on the mechanical ventilation. Each dog was evaluated for the gastric mucosal pH, $CO_{2}$ partial Pressure, arterial pH, $CO_{2}$ partial pressure, the exhaled air $CO_{2}$ partial pressure and the level of IL-8 on before the cardiopulmonary bypass, 1 hour after the cardiopulmonary bypass, 2 hours after the cardiopulmonary bypass, 2 hours after the restoration of normal circulation, and 4 hours after the restoration of normal circulation after the cardiopulmonary bypass. The levels of IL-8 were measured with ELISA (enzyme linked immunosorbent assay) technique. Result: 1. There were significant differences of gastric mucosal $CO_{2}$ partial pressure between the leukocyte-depleted homologous blood group and other two groups(vs non leukocyte-depleted homologous blood group; P=0.02, vs non-hemic crystalloid solution group; P=0,01). 2. The gastric mucosal pH of leukocyte-depleted homologous blood group was significantly different from non leukocyte-depleted homologous blood group (p=0.01). 3. The levels of IL-8, which examine the systemic inflammation, showed signi- ficantly better results in leukocyte-depleted homologous blood group and non-hemic crystalloid solution group than non leukocyte-depleted homologous blood group (p=0.01, 0.01). Conclusion: Based upon these results, we concluded that the leukocyte depletion from the pump-oxygenator priming solution has a beneficial effects in reducing systemic inflammation and the preserving of gastric mucosal micro-circulation.

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.

Objectives: The object of this study was to observe the protective effect of Gamijipaesan aqueous extracts(GJS), which has been traditionally used in Korean medicine in obstetrics & gynecological fields as anti-infectious and anti-inflammatory agents, against mastitis induced by Staphylococcus aureus infection in a rat model through antibacterial, antiinflammatory, immunomodulatory, and anti-oxidant effects. Methods: Antibacterial activities of GJS against S. aureus were detected using standard agar microdilution methods, with the effects on the bacterial invasion and intracellular killing of individual test materials in human mammary gland carcinoma cell(MCF-7) and murine macrophages(Raw 264.7) at MIC1/2, MIC and MIC2 concentration levels. In addition, the effects on the cell viability, nitric oxide(NO), tumor necrosis factor(TNF)-${\alpha}$ and interleukin (IL)-6 productions of LPS activated Raw 264.7 cells. The changes on the mammary tissue viable bacterial numbers, myeloperoxidae(MPO), inducible nitric oxide synthetase(iNOS), TNF-${\alpha}$ and IL-6 contents were observed in the S. aureus in vivo intramammary infectious rat model. The anti-bacterial and anti-inflammatory effects were compared with ciprofloxacin and piroxicam, respectively in the present study. Results: MIC of GJS and ciprofloxacin against S. aureus were detected as $0.860{\pm}0.428$ (0.391-1.563) mg/ml and $0.371{\pm}0.262$(0.098-0.782) ${\mu}g/ml$, respectively. In addition, GJS and ciprofloxacin were also showed marked dosage-dependent inhibition of the both bacterial invasion and intracellular killing assays using MCF-7 and Raw 264.7 cells at MIC1/2, MIC and $MIC{\times}2$ concentrations, respectively. $ED_{50}$ against LPS-induced cell viabilities and NO, TNF-${\alpha}$ and IL-6 releases of GJS were detected as 0.72, 0.04, 0.08 and 0.11 mg/ml, and as 19.04, 4.18, 5.37 and 4.27 ${\mu}g/ml$ in piroxicam, respectively. 250 and 500 mg/kg of GJS also inhibit the intramammary bacterial growth, MPO, iNOS, TNF-${\alpha}$ and IL-6 contents in S. aureus in vivo intramammary infected rats, respectively. GJS 500 mg/kg showed quite similar antibacterial and anti-infectious effects as compared with ciprofloxacin 40 mg/kg and also showed similar anti-inflammatory effects as piroxicam 10 mg/kg, in S. aureus in vivo intramammary infectious models. Conclusions: The results obtained in this study suggest that over 250 mg/kg of GJS showed favorable anti-infectious effects against S. aureus infection in a rat model through their antibacterial, anti-inflammatory, immunomodulatory and anti-oxidant effects and therefore expected that GJS can be used as alternative therapies, having both anti-inflammatory and anti-infectious activities. However, more detail mechanism studies should be conducted in future with the efficacy tests of individual herbal composition of GJS and the screening of the biological active compounds in individual herbs. In the present study, GJS 500 mg/kg showed quite similar anti-infectious effects were detected as compared with ciprofloxacin 40 mg/kg treated rats, and also GJS shows quite similar anti-inflammatory effects as compared with piroxicam 10 mg/kg in S. aureus in vivo intramammary infectious rats, but ciprofloxacin did not showed any anti-inflammatory effects, and piroxicam did not showed anti-infectious effects in this study.

Purpose : Abnormal activation patterns of Th1/Th2-cells have been suggested to increase the prevalence of allergic diseases. Prevention is regarded as an important corner stone in the management of allergic diseases. In this study, we have investigated the relationship between cord blood levels of IL-4, IL-10, and IL-12 in preterm newborns and the development of allergic respiratory diseases in infancy Methods : Forty-six preterm newborns born at the Ewha Womans University Mokdong Hospital between January 2003 and July 2005, were enrolled for this study, and consent was obtained to test their cord blood samples. Clinical history was obtained from the hospital records. Cord blood was obtained at birth and kept frozen until it was tested. The levels of IL-4, IL-10, and IL-12 were determined by enzyme-linked immunosorbent assay (ELISA). Results : All infants were followed-up for a median of $16.0months{\pm}13.2d$ (range, 12.0 to 36.0 months). Eighteen infants who developed wheezing showed lower cord blood levels of IL-12 ($366.60{\pm}140.40$ vs $435.09{\pm}91.20pg/mL$, P=0.009). Cord blood levels of IL-4 and IL-10 showed no significant difference between the two groups. Four newborns who later developed asthma, and infants with asthma showed lower IL-12 level in the cord blood than other groups. Conclusion : Lower concentration of cord blood levels of IL-12 in newborns who later developed wheezing and asthma suggested that they had abnormal activation patterns of Th1/Th2-cells at the time of birth, and cord blood IL-12 level can be used as a predictor of allergic respiratory diseases.

This study was conducted to investigate the hormonal changes in cultured medium during in vitro culture of bovine oviduct epithelial cells (BOEC) supplemented with interleukin (IL)-4 of 0.001, 0.01, 0.1 or 1 ng/ml. BOEC were collected from the oviduct and washed 3 times with 1% antibiotic-mycotic-DMEM medium and cultured at $39^{\circ}C$, 5% $CO_2$, 95% air for 24$\sim$120 hrs. The cultured media were analyzed hormonal changes with hormonal analyzing kit (progesterone (P4), estradiol (E2) : Perkin Elmer, USA) and Transforming growth factor (TGF)-$\beta$ with Eliza kit (Promega, USA). The production of P4 in 0.001 IL-4 was increased as the culture time increased. P4 production was significantly higher in the medium cultured for 120 hrs than 24 hrs (P<0.05). P4 production in 0.01 ng/ml group was similar to that of 0.001 ng/ml. The production of E2 in 0.001 and 0.01 ng/ml groups were increased to 72 hrs like P4 production and showed significantly different between the culture periods (P<0.05). After the culture for 96 hrs, P4 and E2 production were increased to 96 hrs, but decreased at 120 hrs. The production of TGF-$\beta$ showed no changes according to culture period or supplementation of IL-4. In conclusion, the supplementation of IL-4 can increase the production of P4 and E2 and might have important role for the successful pregnancy in bovine.

The experimental exposure of animals to sources of ultraviolet radiation (UVR) which emit their energy primarily in the UVB region (280-320nm) is known to result in a number of well-described changes in the recipient's immune competence. Two such changes include a depressed capacity to effectively respond immunologically to transplants of syngeneic UVR tumors and a markedly reduced responsiveness to known inducers of delayedtype (DTH) and contact hypersensitivity (CH) reactions. The results of experiments that were designed to elucidate the mechanisms responsible for UVR-induced immunomodulation have implicated: 1) an altered pattern of lymphocyte recirculation, 2) suppressor T cells(Ts), 3) deviations in systemic antigen presenting cell (APC) potential. 4) changes in the production of interleukin-1-like molecules, and 5) the functional inactivation of epidermal Langerhans cells in this process. The exposure of skin to UVR, therefore, causes a number of both local and systemic alterations to the normal host immune system. In spite of this seeming complexity and diversity of responses, our recent studies have established that each of the UVR-mediated changes is probably of equal importance to creating the UVR-induced immunocompromised state. Normal animals were exposed to low dose UVR radiation on their dorsal surfaces under conditions where a $3.0\;cm^2$ area of skin was physically protected from the light energy. Contact sensitization of these animals with DNFB, to either the irradiated or protected back skin, resulted in markedly reduced CH responses. This was observed in spite of a normal responsiveness following the skin sensitization to ventral surfaces of the UVR-exposed animals. Systemic treatment of the low dose UVR recipients with the drug indomethacin (1-3 micrograms/day) during the UVR exposures resulted in a complete reversal of the depressions observed following DNFB sensitization to "protected" dorsal skin while the altered responsiveness found in the group exposed to the skin reactive chemical through directly UVR-exposed sites was maintained. These studies implicate the importance of EC as effective APC in the skin and also suggest that some of the systemic influences caused by UVR exposure involve the production of prostaglandins. This concept was further supported by finding that indomethacin treatment was also capable of totally reversing the systemic depressions in CH responsiveness caused by high dose UVR exposure (30K joules/$m^2$) of mice. Attempts to analyze the cellular mechanisms responsible established that the spleens of all animals which demonstrated altered CH responses, regardless of whether sensitization was through a normal or an irradiated skin site, contained suppressor cells. Interestingly, we also found normal levels of T effector cells in the peripheral lymph nodes of the UVR-exposed mice that were contact sensitized through normal skin. No effector cells were found when skin sensitization took place through irradiated skin sites. In spite of such an apparent paradox, insight into the probable mechanisms responsible for these observations was provided by establishing that UVR exposure of skin results in a striking and dose-dependent blockade of the efferent lymphatic vessels in all peripheral lymph nodes. Therefore, the afferent phases of immune responses can apparently take place normally in UVR exposed animals when antigen is applied to normal skin. The final effector responses, however, appear to be inhibited in the UVR-exposed animals by an apparent block of effector cell mobility. This contrasts with findings in the normal animals. Following contact sensitization, normal animals were also found to simultaneously contain both antigen specific suppressor T cells and lymph node effector cells. However, these normal animals were fully capable of mobilizing their effector cells into the systemic circulation, thereby allowing a localization of these cells to peripheral sites of antigen challenge. Our results suggest that UVR is probably not a significant inducer of suppressor T-cell activity to topically applied antigens. Rather, UVR exposure appears to modify the normal relationship which exists between effector and regulatory immune responses in vivo. It does so by either causing a direct reduction in the skin's APC function, a situation which results in an absence of effector cell generation to antigens applied to UVR-exposed skin sites, inhibiting the capacity of effector cells to gain access to skin sites of antigen challenge or by sequestering the lymphocytes with effector cell potential into the draining peripheral lymph nodes. Each of these situations result in a similar effect on the UVR-exposed host, that being a reduced capacity to elicit a CH response. We hypothesize that altered DTH responses, altered alloresponses, and altered graft-versus-host responses, all of which have been observed in UVR exposed animals, may result from similar mechanisms.

This study aimed to evaluate the dietary effect of organic sulfur (OS) supplementation on performance, egg quality and serum constituents in laying hens. A total of 360 Lohmann brown laying hens at the age of 31 weeks were distributed into four treatments having five replicates of 18 hens each until 54 weeks. The hens were fed four levels (0.0, 0.1, 0.2 and 0.4%) of OS with basal diet. The number of eggs was investigated daily, and egg quality was confirmed every 8 weeks. Sulfur content in eggs, interleukin 2 (IL-2), T help cells (CD4+) and cytotoxicity cells (CD8+) were measured at the termination of the experiment. The result of the study showed that egg production tended to increase with 0.4% OS in diet after 39 weeks of age and, there was a significant effect (P<0.05) from 47 to 54 weeks of age. Egg quality traits of albumen height and haugh unit increased significantly (P<0.05) owing to the addition of OS to the diet. The polyunsaturated fatty acids in yolk were gradually increased while saturated fatty acids were decreased with increasing levels in OS (P<0.05). Total sulfur concentration in the eggs increased significantly (P<0.05) in treatments fed OS. Moreover, albumin, AST and HDL cholesterol levels in serum improved significantly (P<0.05) owing to the addition of OS. The IL-2 concentration and the ratio of CD4+ and CD8+ in blood were generally higher (P<0.05) at 0.4% OS. Therefore, it can be recommended that supplementary OS diet affected the performance, egg quality and stimulated immune response in laying hens.

In order to investigate anti-inflammatory, anti-allergic and anti-obesity activities of Samchulkunbi-tang (SCT; Shen zhu jian pi-tang) water and 70% ethanol (EtOH) extracts, in vitro inhibitory activities against nitric oxide (NO), prostaglandin $E_2$ $PGE_2$), interleukin (IL)-6 and tumor necrosis factor (TNF)-${\alpha}$ production in lipopolysaccharide-stimulated RAW 264.7 cells, and macrophage-derived chemokine (MDC/CCL22) and regulated on activation of normal T-cell-expressed and -secreted (RANTES/CCL5) production in TNF-${\alpha}$/interferon-${\gamma}$-stimulated HaCaT and BEAS-2B cells as well as glycerol-3-phosphate dehydrogenase (GPDH) activity and leptin production in 3T3-L1 cells were determined. A HPLC was used for quantification of the seven marker components (albiflorin, paeoniflorin, liquiritin, naringin, hesperidin, poncirin and glycyrrhizin) of SCT water and 70% EtOH extracts. SCT showed inhibitory effects against MDC and RANTES production in HaCaT cells, as well as RANTES production in BEAS-2B cells. In addition, SCT reduced not only NO, $PGE_2$, IL-6 and TNF-${\alpha}$ production in RAW 264.7 cells, but also GPDH activity and leptin production in 3T3-L1 cells. Furthermore, the biological activities and the contents of six compounds (except paeoniflorin) were higher in 70% EtOH extract than water extract. These results suggest that SCT has anti-inflammatory, anti-allergic and anti-obesity activities. These efficacies of 70% EtOH extract are relatively higher than that of water extract.

Propolis is the generic term for the resinous substance collected by honey bees from a variety of plant sources. In this study, we have assessed the immunomodulatory properties of propolis (P) and fermented-propolis (FP) in BALB/c mice. Mice were subjected to gavage once a day (for 14 days) with 50, 100, 200 mg/kg body weight P, FP, or vehicle. Lymphocytes were isolated from the spleen and mesenteric lymph nodes (MLN) and the immune cell proportions, proliferative activities, and cytokine production were evaluated. The P- and FP-administration induced similar, but differential, alterations in the percentage of immune cell populations and their biological functions, including cytokine production and NK cell cytotoxicity. The proportion of$ CD4^+$ and $CD8^+$ T cells in the spleen was increased slightly in the P- and FP-administered mice as compared to the vehicle-treated mice. In MLN, the percentage of $CD4^+$ T cells was increased significantly in the 200 mg/kg P-treated mice. The mice which were treated with P and FP evidenced significantly increased interferon-$\gamma$ and interleukin-4 production in concanavalin A-stimulated splenocytes, whereas the production of theses cytokines was not shown to be induced by P-treatment. In addition, NK cell activity was also increased dramatically by the administration of P and FP. Collectively, these findings showed that P and FP are wide-spectrum immunomodulators, which may modulate both innate and adaptive immune responses.
