Objective: This study was eanied out to investigate the effects of Raphani Semen on immuno-response in the mouse model of allergic asthma. Methods: In this study, BALB/C mice were divided into 6 groups: Normal (Non-treated group), Control (Group with not treated after allergic sensitization and induction by ovalbumin), Treat I (Group with the oral administration of saline after allergic sensitization and induction by ovalbumin), Treat n (Allergic asthma group treated with acupuncture (BL 13)), Treat III (Allergic asthma group treated with the oral administration of Raphani Semen) and Treat lV (Allergic asthma group treated with the herbal-acupuncture of Raphani Semen (BL 13)). The effect on cytokine was assessed by measuring cytokine (lL-2, IL-4, IL-5, IL-10, IL-12, IFN-r) in bronchoalveoar lavage fluid(ELISA). ResuJts : The results obtained as follows: 1. The production of Interleukin-2 was decreased significantly in Treat I group, Treat n group and Treat IV group as compared with Control group. 2. The production of Interleukin-4 was decreased significantly in Treat I group, Treat II group and Treat IV group as compared with Control group. Among them. the production of Interleukin-4 was decreased remarkably in Treat IV group as compared with other groups. 3. The production of Interleukin-5 was decreased significantly in Treat I group and Treat IV group as compared with Control group. 4. The production of Interleukin-10 was decreased significantly in Treat I group and Treat III group as compared with Control group. 5. The production of Interleukin-12 was all decreased significantly in Treat I group, Treat n group, Treat m group and Treat IV group as compared with Control group. 6. The production of Intelferon- showed no significant changes in Treat I group, Treat n group. Treat m group and Treat Ⅳ group as compared with Control group. Conclusion: These results show that the production of Interleukin-4, 5 was decreased significantly in aJlergic asthma group treated with the herbal-acupuncture of Raph Semen (BL 13), It is known that inactivity of Th2 cell constrained the revelation and controlled hypersenstive action. As to this mechanism, it is suggested that the herbal-acupuncture of Raphani Semen(BL 13) constrained the revelation of allergic asthma.

This experiment was designed to study possible roles of $interleukin-1\beta$, interleukin-6 and tumor necrosis $factor-\alpha$ in bone remodeling by measuring their effects on $PGE_2,\; LTB_4$ and collagenase production when they were administered to human periodontal ligament fibroblasts. Human periodontal ligament fibroblasts were collected from first premolars extracted for orthodontic treatment. They were incubated in the environment of $37^{\circ}C,\;5\%\;Co^2,\;and\;100\%$ humidity. They were treated with $0.25\%$ trypsin-EDTA solution and centrifuged. PDL cells in the fifth to seventh passage were used for the experiment. Cells were seeded onto the culture dishes and when they were successfully attached, human recombinant $interleukin-1\beta$, interleukin-6, and tumor necrosis $factor-\alpha$ were administered, alone or in combination. They were incubated for 4, 8 and 24 hours and the levels of $PGE_2,\;LTB_4$ and collagenase released into the culture media were assessed by enzymeimmunoassay and collagenase activity assay. The conclusions are as follows: 1. $IL-1\beta\;and\;TNF-\alpha$ were very active in stimulating the production of $PGE_2$ and collagenase by human periodontal ligament fibroblasts, while IL-6 increased $LTB_4$ production. 2. $IL-1\beta$ significantly increased $PGE_2$, but $LTB_4$ Production was not increased. $IL-1\beta$ is thought to act mainly via the cyclooxygenase pathway of arachidonic acid metabolism. 3. IL-6 tended to inhibit $IL-1\beta$ in the production of $PGE_2$ and collagense whereas IL-6 and $TNF-\alpha$ showed auditive effect in the level of $PGE_2$. The above cytokines increased the release of at least one of $PGE_2,\;LTB_4$ and collagenase. It suggests that cytokines are involved in bone remodeling process by stimulating PDL fibroblasts to produce various bone-resorptive agents. The roles of cytokines in bone remodeling as a whole would need further study.

Purpose: Early diagnosis and treatment of acute pyelonephritis in children is of special importance in order to prevent serious complications. This study was conducted to determine the diagnostic value of serum interleukin (IL)-6 and IL-8 in children with acute pyelonephritis. Methods: Eighty-seven patients between 1 month to 12 years old with urinary tract infection (UTI) were divided into 2 groups based on the result of 99m-technetium dimercapto-succinic acid renal scan: acute pyelonephritis (n=37) and lower UTI (n=50) groups. White blood cell (WBC) count, neutrophil (Neutl) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, platelet count, and serum IL-6 and IL-8 concentrations of both groups were measured and compared. Results: There was a significant difference between two groups regarding WBC count, Neutl count, ESR, and CRP concentration (P<0.05). In addition, the difference between the two groups regarding serum IL-6 and IL-8 concentrations was not significant (IL-6, 60 and 35.4 pg/mL and IL-8, 404 and 617 pg/mL, respectively). The sensitivity and specificity of serum IL-6 and IL-8 for diagnosis of acute pyelonephritis were 73%, 42% and 78%, 32%, respectively. Sensitivity, specificity, negative and positive predictive values of serum IL-6 and IL-8 were less than those of acute phase serum reactants such as CRP. Conclusion: This study showed that there was no significant difference between acute pyelonephritis and lower UTI groups regarding serum IL-6 and IL-8 levels. Therefore, despite confirming results of previous studies, it seems that IL-6 and IL-8 are not suitable markers for differentiating between acute pyelonephritis and lower UTI.

Falun Gong (FG) is an advanced system of cultivation and practice, which is beneficial for both mind and body. In this study we investigated the effects of FG on the production of cytokines in FG practitioner (FGP). To study whether plasma cytokines levels were affected by FG, their levels were analyzed. The amount of $interferon-{\gamma}$ $(IFN-{\gamma})$, interleukin (IL)-2, IL-4 and IL-6 (2.5-fold for $IFN-{\gamma}$, 1.2-fold for IL-2, 2.1-fold for IL-4 and 2.5-fold for IL-6, respectively) were significantly higher in the FGP group than normal group (P<0.05). Peripheral blood mononuclear cells obtained from normal healthy control and FGP were cultured for 24 h in the presence or absence of lipopolysaccharide. The amount of $IFN-{\gamma}$, IL-2, IL-4 and IL-6 in culture supernatant was quantified. However, there were no significant differences in the level of the same cytokines between the normal and FGP group. These data suggest that FG cultivation may contribute to immune-enhancement in vivo.

Pheochromocytomas and paragangliomas (PPGLs) may secrete hormones or bioactive neuropeptides such as interleukin-6 (IL-6), which can mask the clinical manifestations of catecholamine hypersecretion. We report the case of a patient with delayed diagnosis of paraganglioma due to the development of IL-6-mediated systemic inflammatory response syndrome (SIRS). A 58-year-old woman presented with dyspnea and flank pain accompanied by SIRS and acute cardiac, kidney, and liver injuries. A left paravertebral mass was incidentally observed on abdominal computed tomography (CT). Biochemical tests revealed increased 24-hour urinary metanephrine (2.12 mg/day), plasma norepinephrine (1,588 pg/mL), plasma normetanephrine (2.27 nmol/L), and IL-6 (16.5 pg/mL) levels. ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/CT showed increased uptake of FDG in the left paravertebral mass without metastases. The patient was finally diagnosed with functional paraganglioma crisis. The precipitating factor was unclear, but phendimetrazine tartrate, a norepinephrine-dopamine release drug that the patient regularly took, might have stimulated the paraganglioma. The patient's body temperature and blood pressure were well controlled after alpha-blocker administration, and the retroperitoneal mass was surgically resected successfully. After surgery, the patient's inflammatory, cardiac, renal, and hepatic biomarkers and catecholamine levels improved. In conclusion, our report emphasizes the importance of IL-6-producing PPGLs in the differential diagnosis of SIRS.

Objective: To determine the interleukin (IL)-6 levels in gingival crevicular fluid (GCF) of patients with severe root resorption after orthodontic treatment and investigate the effects of different static compressive forces (CFs) on IL-6 production by human periodontal ligament (hPDL) cells and the influence of IL-6 on osteoclastic activation from human osteoclastic precursor (hOCP) cells in vitro. Methods: IL-6 levels in GCF samples collected from 20 patients (15 and 5 subjects without and with radiographic evidence of severe root resorption, respectively) who had undergone orthodontic treatment were measured by ELISA. The levels of IL-6 mRNA in hPDL cells and IL-6 protein in conditioned medium after the application of different uniform CFs (0, 1.0, 2.0, or 4.0 $g/cm^2$ for up to 72 h) were measured by real-time PCR and ELISA, respectively. Finally, the influence of IL-6 on mature osteoclasts was investigated by using hOCP cells on dentin slices in a pit-formation assay. Results: Clinically, the IL-6 levels were significantly higher in the resorption group than in the control group. In vitro, IL-6 mRNA expression significantly increased with increasing CF. IL-6 protein secretion also increased in a time- and magnitude-dependent manner. Resorbed areas on dentin slices were significantly greater in the recombinant human IL-6-treated group and group cultured in hPDL cell-conditioned medium with CF application (4.0 $g/cm^2$) than in the group cultured in hPDL cell-conditioned medium without CF application. Conclusions: IL-6 may play an important role in inducing or facilitating orthodontically induced inflammatory root resorption.

Rheumatoid arthritis (RA) is an autoimmune/inflammatory disorder with a complex genetic component. RA is characterized by chronic inflammation of the synovial membrane in the joint, which leads to the progressive destruction of articular cartilage, ligament and bone. Several cytokines such as tumor necrosis $factor-{\alpha}\;TNF-{\alpha}\;and\;interleukin-1{\beta}\;(IL-1{\beta})$ and interleukin-6 (IL-6) have been implicated in the pathological mechanisms of synovial tissue proliferation, joint destruction and programmed cell death in rheumatoid joint. Genome wide screening of subjects suffering from autoimmune diseases especially arthritis revealed linkage to inflammatory molecules like $TNF-{\alpha},\;IL-1{\beta}$ and IL-6, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nuclear factor-kappaB $(NF-{\kappa}B)$ and human leucocyte antigen/major histocompatibility complex (HLA/MHC) locus. The status of the pharmacological mechanism of herbal drugs in the light of genome wide screening results has been discussed to reinforce the therapeutic potential and the pharmacological basis of the herbal drugs.

Diabetes mellitus is associated with vascular complications. Diabetic patients exhibit high levels of glycated adducts in serum compared to non-diabetic individuals. The aim of this study was to investigate whether extracellular glycated albumin (GA) predisposes vascular smooth muscle cells (VSMCs) to pro-inflammatory phenotype. Exposure of rat aortic smooth muscle cells (AoSMCs) to GA not only enhanced interleukin-6 (IL-6) release but also activated promoter activity of the IL-6 gene. GA-induced IL-6 promoter activation was suppressed by dominant-negative forms of Toll-like receptor (TLR)-4 and myeloid differentiation factor 88 (MyD88), but not by dominant-negative-forms of TLR-2 and TIR-domain-containing adapter-inducing interferon-$\beta$ (TRIF). Extracellular signal-regulated kinase (ERK) inhibition and diphenyleneiodium (DPI) also attenuated IL-6 induction by GA. Mutation at the nuclear factor-${\kappa}B$ (NF-${\kappa}B$)-binding site in the IL-6 promoter region suppressed promoter activation in response to GA. The present study proposes that GA would contribute to inflammatory reaction in the stressed vasculature by inducing IL-6 in VSMCs, and that TLR-4, EKR, and NF-${\kappa}B$ play active roles in the process.

Novel chalcones were found as potent inhibitors of interleukin-5 (II-5). 1-(6-Benzyloxy-2-hydroxyphenyl)-3-(4-hydroxyphenyl)propenone (2a, 78.8% inhibition at $50\;{\mu}M,\;IC_{50}=25.3\;{\mu}M$) was initially identified as a potent inhibitor of IL-5. This activity is comparable to that of budesonide or sophoricoside (1a). The benzyloxy group appears to be critical for the enhancement of the IL-5 inhibitory activity. To identify the role of this hydrophobic moiety, cyclohexyloxy (2d), cyclohexylmethoxy (2c), cyclohexylethoxy (2e), cyclohexylpropoxy (2f), 2-methylpropoxy (2g), 3-methylbutoxy (2h), 4-methylpentoxy (2i), and 2-ethylbutoxy (2j) analogs were prepared and tested for their effects on IL-5 bioactivity. Compounds 2c ($IC_{50}=12.6\;{\mu}M$), 2d ($IC_{50}=12.2\;{\mu}M$), and 2i ($IC_{50}=12.3\;{\mu}M$) exhibited the most potent activity. Considering the cLog P values of 2, the alkoxy group contributes to the cell permeability of 2 for the enhancement of activity, rather than playing a role in ligand motif binding to the receptor. The optimum alkoxy group in ring A of 2 should be one that provides the cLog P of 2 in the range of 4.22 to 4.67.
