Balb/c mouse spleen cells in vitro sensitized against ICR spleen cells were cultured in conditioned media(CM). The CM was produced by ICR spleen cells stimulated with Concanavalin-A(Con-A), and sensitized lymphoid cells were grown in CM. ICR mouse spleen cells were appeared to be a good generator of IL-2. Optimal growth was seen in growth medium containing 20% fetal calf serum. and 25% CM. When cultures were initiated at 1, 5, $10{\times}10^4\;cells/ml$, the cells were increased in numbers by about 20, 13, 5-fold, respectively, every 9 days. Such growth pattern was sustained for about 4-6 weeks and thereafter the cell growth was diminished gradually. Direct immunofluorescence indicated that 93% of the lymphoid cells grown in CM(for 10 days) expressed Thyl surface antigen. And the cells grown in CM were cytotoxic to the sesitizing ICR mouse spleen cells though cytotoxicity level was not high. According to these results, the cells grown in CM were considered to be cytotoxic T lymphocytes. The lymphoid cells grown for 20 days were nearly unresponsive to Con-A and therefore dependent only IL-2 to be used for IL-2 assay.

Aim: Historically, mineral compound herbal medicines have long been used in treatments of immune-related diseases in Korea, China and other Asian countries. In this study, we investigated the anti-inflammatory effect of egg white combined with chalcanthite (IS4) on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Methods: RAW 264.7 cells cultured with LPS and various concentrations of IS4 were analyzed to determine the production of pro-inflammatory cytokines and mediators by using enzyme-linked immune sorbent assays (ELISAs). Results: IS4 concentration inhibited the production of interleukin-1beta (IL-$1{\beta}$), interleukin-6 (IL-6), and granulocyte-macrophage colony-stimulating factor (GM-CSF) induced by LPS. IS4 at high concentrations (25 and 50 ${\mu}g/ml$) inhibited, in concentration-dependent manner, the expression of tumor necrosis factor-alpha (TNF-${\alpha}$) stimulated by LPS. Conclusion: IS4 has shown an anti-inflammatory effect in RAW 264.7 cells.

The purpose of this study is to investigate effects of White Ginseng-Ejung-tang water extract (EJ) on production of various cytokines such as interleukin (IL)-2, IL-5, IL-6, IL-10, IL-12p70, macrophage inflammatory protein (MIP)-2, vascular endothelial growth factor (VEGF), keratinocyte-derived chemokine(KC), tumor necrosis factor (TNF)-${\alpha}$, and granulocyte macrophage colony-stimulating factor (GM-CSF) in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Levels of cytokines were measured by High-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. EJ significantly decreased levels of IL-2, IL-12p70, IL-5, MIP-2 for 24 h incubation at the concentrations of 25, 50, and 100 ${\mu}g/mL$ in LPS-induced RAW 264.7 (P < 0.05). EJ significantly decreased levels of IL-6 at the concentrations of 50 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of IL-10 and VEGF at the concentrations of 25 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of KC at the concentrations of 100 ${\mu}g/mL$ (P < 0.05). EJ did not show any significant effect on TNF-${\alpha}$ and GM-CSF production. These results suggest that EJ has anti-inflammtory property related with its inhibition of IL-2, IL-5, IL-6, IL-10, IL-12p70, MIP-2, VEGF, and KC production in LPS-induced macrophages.

Background: Immune responses appear to be affected by anesthetics and analgesics. We investigated the effects of caudal tramadol on the postoperative immune response and pain management in pediatric patients. Methods: Sixty ASA-I pediatric patients aged 3-10 years undergoing lower abdominal surgery. Patients were randomly assigned either to a caudal bupivacaine (0.25%) group (group B), or a group that received caudal tramadol (1 mg/kg) added to the bupivacaine (0.25%) (group T). Both were diluted in a 0.9% NaCl solution to a total volume of 1ml/ kg. The systemic immune response was measured by collecting blood samples preoperatively, at the end of anesthesia, and at 24 and 72 hours postoperatively, and studied for interleukin IL-6, C-reactive proteins (CRP) cortisol levels, and leucocytes with its differential count. Postoperative pain was assessed along with sedation scales. Results: Postoperative production of IL-6 was significantly higher in group B at the end of anesthesia, than at the $24^{th}$ hour, and at the $72^{nd}$ hour in group B and group T, respectively. The immune response showed leukocytosis with increased percentages of neutrophil and monocytes, and a decreased lymphocyte response rate within both groups with no significant differences between the groups. Cortisol and CRP were significantly higher in group B. Conclusions: Adding tramadol to a caudal bupivacaine block can attenuate the pro-inflammatory cytokine response, Cortisol, and CRP in children undergoing lower abdominal surgery.

Immunoregulatory cytokines have an influence on hepatitis C virus (HCV) infection outcome. This study aimed to determine whether single nucleotide polymorphisms (SNP) in IFN- ${\gamma}$ and IL-10 genes are associated with susceptibility and/or are markers of prognosis regarding chronic hepatitis C outcomes. IFN ${\gamma}$ (+874T/A) and IL-10 (-1082G/A) genotypes were determined in 75 HCV genotype 4 patients with different disease severities (chronic hepatitis, n=25, liver cirrhosis and hepatocellular carcinoma (HCC) on top of liver cirrhosis, n=50) and 25 healthy participants using allele-specific polymerase chain reaction. No statistical differences in allele or genotype distributions of IFN ${\gamma}$ and IL-10 genes were detected between patients and controls or between patientgroups. No significant difference in the frequency of IL-10 SNP at position -1082 or IFN-${\gamma}$ at position +874T/A was found between chronic HCV genotype 4 and with progression of disease severity in liver cirrhosis or HCC. In conclusion; interferon-${\gamma}$ and interleukin-10 gene polymorphisms are not predictors of disease progression in patients with chronic hepatitis C (Genotype-4).

Korean red ginseng (Panax ginseng Meyer) is a well-known traditional medicine, with numerous biological functions in the body. Portulaca oleracea (P. ole) belongs to the Portulacaceae family and has bioactive potential as a traditional medicine. This study aimed to determine the anti-inflammatory effects of Korean red ginseng extract (RGE) and P. ole extract on lipopolysaccharide (LPS)-treated RAW 264.7 cells. The combination of RGE (50 ㎍/mL) and P. ole (6.25 ㎍/mL) extracts significantly suppressed LPS-induced nitric oxide synthesis. The expression of proinflammatory mediators, including inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and proinflammatory cytokines, including interleukin-1β, interleukin-6, and tumor necrosis factor-α, were markedly decreased by the combined treatment with RGE (50 ㎍/mL) and P. ole (6.25 ㎍/mL). Moreover, iNOS and COX-2 protein expression levels were also significantly reduced in the combined treatment compared to the LPS-stimulated group. In addition, the nuclear translocation of phosphorylated nuclear factor kappa-B was suppressed by the treatment with RGE and P. ole. Moreover, the mitogen-activated protein kinase pathway was also partially inhibited by the combination treatment with RGE and P. ole. Our results demonstrate that the treatment mixture with RGE and P. ole could be used as functional food and therapeutic herbal medicine in various inflammatory diseases.

Objective: The present research was conducted to evaluate the interactive effect of dietary concentration of calcium (Ca) and 25-hydroxy vitamin D3 (25OHD3) on the performance, blood composition and digestibility of laying hens. Methods: A total of 540 Hy-line brown laying hens aged 61 to 70 weeks were randomly allotted in a 3×3 factorial arrangement, consisting of three levels of 25OHD3 (0, 25, and 50 ㎍/kg) and three levels of Ca (3.5%, 4.0%, and 4.5%). All diets had basal concentration of 3,000 IU/kg of vitamin D3 including the 2,800 kcal/kg of metabolic energy and 16% of crude protein. Results: The results showed that interactive effect (p<0.05) between Ca and 25OHD3 was such that dietary 25OHD3 linearly increased interleukin-6 at all levels of Ca inclusion. Interaction (p<0.05) occurred with the highest parathyroid hormone in laying hens that received dietary concentration of Ca (3.5%) with 25OHD3 (50 ㎍/kg), and Ca (4.0%) with 25OHD3 (50 ㎍/kg). Egg production and egg weight significantly (p<0.05) increased in the 4.5% Ca group compared to the 3.5% to 4.0% Ca groups. Egg shell thickness and tibia bone length also increased (p<0.05) in groups fed a high-Ca diet (4.0% to 4.5%). Phosphorus digestibility significantly (p<0.05) increased along with dietary Ca level. Among the tested 25OHD3 groups, higher (p<0.05) egg production and tibia thickness were present in hens fed 50 ㎍/kg of 25OHD3. Furthermore, Ca digestibility serum Ca and 25OHD3 were significantly increased in group offered 50 ㎍/kg of 25OHD3. Conclusion: The results gathered in this study indicate that dietary concentrations of 4.0% to 4.5% Ca and 50 ㎍/kg 25OHD3 improve the performance of hens from 61 to 70 weeks of age.
