  • This experiment was designed to investigate the effect of Gamcho(Glycyrrhiza uralensis Fisch, GLU) in asthma. We measured histamine, IL-1β, IL-4, 1L-5, IL-6, IL-10, IL-13, in plasma of ovalbumin induced asthmatic mouse. The results were obtained as follows: GLU decreased the proliferation of histamine, IL-1β, IL-4, IL-5, IL-6, IL-13 significantly. GLU increased the proliferation of IL-10 significantly. According to the above results, it is suggested that GLU extract might be useful applied for prevention and treatment of allergic asthma.

  • We investigated the possible association of interleukin-10 (IL-10) single nucleotide polymorphisms (SNPs) and susceptibility to acute myeloid leukemia (AML) in 115 patients and 137 healthy controls. Genetic analysis of IL-10 SNPs at -819 and -592 was carried out with the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) approach. The IL-10 mRNA expression of AML patients and controls with different genotype was detected by real-time quantitative polymerase chain reaction (RT-PCR). Genetic analysis of IL-10 revealed that the -819AA genotype frequencies and the -819A allele frequencies in the AML group were higher than in the controls (59.1% vs 40.9%; 75.6% vs 63.9%, respectively); there were remarkable differences in -819T/C and -592A/C gene distribution (P<0.05) and the TA haploid frequencies were higher in the AML group (75.6% vs 63.9%, P<0.05). IL-10 mRNA expression in incipient AML patients was obvious higher than the non-tumor group and the remission group ($7.78{\times}10^{-3}$ vs $2.43{\times}10^{-3}$, $3.64{\times}10^{-3}$, P<0.05).The study suggested that the haploid TA and genotype TA/TA may be associated with AML in Han people in Hunan province.The IL-10 SNPs at -819 and -592 sites were associated with AML and may affect IL-10 mRNA expression in AML patients.

  • In elderly patients, ocular toxoplasmosis is one of the most common etiologies of uveitis, which should be differentially diagnosed from ocular lymphoma, another common pathology of uveitis in older adults. The high level of interleukin (IL)-10 and an IL-10/IL-6 ratio higher than 1 (>1.0) are helpful parameters to diagnose ocular lymphoma. In this study, we used aqueous humor samples to detect 4 cases of ocular toxoplasmosis in patients with high levels of IL-10 and an IL-10/IL-6 ratio higher than 1. Our results show that ocular toxoplasmosis may be associated with increased cytokine levels in aqueous humor.

  • Objective : Allergic Inflammation is related with secretion of Cytokine. This study was performed to examine the effects of Woobangja on anti-allergic inflammation. Method : While macrophage 264.7cells was chosen as a normal group a control group was classified into three groups. One was stimulated with LPS. and another was pretreated with Woobangja for 1 hour. The third was pretreated with gydrocortisone for 1 hour. After the pretreatment, macrophage were incubated with lipopolysaccharide(LPS) 100 ng/ml for 12h and media collected and $TNF-{\alpha}$, IL-6, $IL-1{\beta}$, IL-10 concentration in supernatants were measured each by Enzyme linked immuno-sorbent assay. Woobangja were used $50\;{\mu}g/ml$, $100\;{\mu}g/ml$, $250\;{\mu}g/ml$, $500\;{\mu}g/ml$, 1 mg/ml. Hydrocortisones were used respectively $10^{-8}\;M$,$10^{-7}\;M$,$10^{-6}\;M$,$10^{-5}\;M$,$10^{-4}\;M$. Results : Woobangja showed inhibitory effect on $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in 1mg/ml(p<0.01), and has increased according to the number of doses. Woobangja also showed inhibitory effect on IL-10 by LPS-stimulated macrophasg 264.7. The inhibitory effect was most significant in $100\;{\mu}g/ml$, and was not in a dose-dependent manner as Hydrocortisone group. Woobangja and Hydrocortison showed contrary effect on $IL-1{\beta}$ in al five concentration(p<0.01), and at the lowest concentration ($50\;{\mu}g/ml$) the level of $IL-1{\beta}$ was the lowest. On the other hand hydrocortison was observed to have inhibitory effect on $IL-1{\beta}$ in all five concentration(p<0.01). IL-6 was inhibited by hydrocortison in a roughly dose-dependent manner, but was not inhibited by Woobangja. On the contrary Woobangja obviously increased the expression of $IL-1{\beta}$ in all five concentration(p<0.01), but it was not related with concentrations. Conclusion : 1. Woobangja does significantly inhibit the expression of $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. 2. Woobangja does significantly increse the expression of IL-6 by LPS-stimulated macrophage 264.7. 3. Woobangja does significantly increse the expression of $IL-1{\beta}$ by LPS-stimulated macrophage 264.7. 4. Woobangja does significantly inhibit the expression of IL-10 by LPS-stimulated macrophage 264.7. 5. Woobangja is observer to have anti-allergic inflammatory effect through inhibiting inflammatory cytokine.

  • Objective: This experimental study was performed to examine the in vitro and in viva anti-inflammatory and anti-allergic effects of Mori Cortex. Methods: Water extract of Mori Cortex was studied to its ability to stimulate or inhibit macrophage 264.7 cells to produce inflammatory and allergic mediators. Cytokines such as $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ were measured by immunochemical assay. In vitro, the macrophages 264.7 were classified into four groups. One group was a normal group. The other group was a (-) control group stimulated with LPS. And the third group was a (+) control group pretreated for 1 hour with hydrocortisone. And the fourth group was a sample group pretreated for 1 hour with Mori Cortex. After pretreatment, macrophage were incubated with lipopolysaccharide(LPS) $100\;ng/m{\ell}$ for 12 hour and media collected and $IL-1{\beta}$, IL-6, IL-10 and $TNF-{\alpha}$ concentrations in supernatants were measured each by Enzyme linked immuno-soubent assay. Mori Cortex were used $50\;{\mu}g/m{\ell},\;100\;{\mu}g/m{\ell},\;250\;{\mu}g/m{\ell},\;500\;{\mu}g/m{\ell},\;and\;1,000\;{\mu}g/m{\ell}$. Hydrocortisones were used $10^{-8}M,\;10^{-7}M,\;10^{-6}M,\;10^{-5}M\;and\;10^{-4}M$. In vivo, the SD rats were classified into three groups. One group was a normal group injected with normal saline into the abdominal cavity. The other was a control group prescribed to compound 48/80 after normal saline injection. And the third was a sample group prescribed to compound 40/80 after Mori Cortex injection. Then, the release of histamine, IL-6 and $TNF-{\alpha}$ were measured. Results : In vitro, Man Cortex significantly increased the release of $IL-1{\beta}\;and\;TNF-{\alpha}$ by LPS-stimulated macrophage 264.7 cells. And it significantly decreased the release of IL-10. In IL-6, Mori Cortex of low concentration significantly decreased the release of IL-6, but that of high concentration acted in reverse. In vivo, Man Cortex didn't show significant inhibitory effects on the release of histamine and IL-6 in comparison with that of the control group. But it significantly increased the release of $TNF-{\alpha}$ in comparison with that of the control group.

  • The transgenic mice carrying human Interleukin-10 (hIL-10) gene in conjunction with bovine (3 -casein promoter express hIL-10 in milk during lactation. In this study, stability of germ line transmission and expression of hIL-10 transgene integrated into host chromosome were monitored up to generation F8 of transgenic mice. When male mouse of generation F8 was crossbred with normal females, approximately half of offspring (50.9±5.8%) were identified as transgenic mice. Generation F9 to F15 mice also showed similar transmission rates (66.0±20.1%, 61.5±16.7%, 41.1±8.4%, 40.7±20.3%, 61.3±10.8%, 49.2±18.8% and 43.8±25.9%, respectively), implying that hIL-10 transgene can be transmitted stably up to long term generation in the transgenic mice. Expression levels of human IL-10 from milk of generation F9 to F14 mice were 3.6± 1.2 mg/ml, 4.2±0.9 mg/ml, 5.7±1.5 mg/ml, 6.3±3.5 mg/ml, 6.8±4.5 mg/ml and 6.8±3.1 mg/ml, respectively, which was showed high-level expression compared with that of generation F1 (1.6 mg/ml) mice. In conclusion, our results suggest that transgenic mice can be continuously passed their transgenes to the progeny through the breeding program with the same productivity of human IL-10 protein in their milk.

  • This study for developing a new anti-inflammatory medicine was sought by investigating the antiinflammatory properties of C. indicum L. extract. Rats were treated with either saline (control) or C. indicum L. extract and then injected with LPS. We found that the plasma concentration of IL-1${\beta}$ IL-6, TNF-${\alpha}$and IL-10 peaked at 5h after LPS injection, and the plasma concentration of IL-6 and TNF-${\alpha}$ showed a tendency to decrease, and IL-10 concentration showed a tendency to increase with increasing levels of C. indicum L. extract. In the liver concentration of cytokines at 5 h post LPS injection, IL-1${\alpha}$ and IL-6 decreased with increasing concentration of C. indicum L. extract, however TNF-${\alpha}$ and IL-10 did not differ significantly the treatment groups.

  • It is becoming increasingly clear that the inflammatory reaction can be ascribed to a complex array of mediators generated and released from activated phagocytes. In this study, the effect of PAF on interleukin-1(IL-1) activity by rat alveolar macrophages(AM) was examined using thymocyte proliferation assay in the supernate of sample obtained after 24 hr culture. When AM were cultured with PAF alone, no change in IL-1 activity was observed. However, the combined addition of PAF and muramyl dipeptide(MDP) or lipopolysaccharide(LPS) to AM cultures markedly enhanced IL-1 activity by 2-3 fold compared with AM cultures with the stimulant alone in a concentration dependent fashion. The peack effect was found at $10^{-8}$ M PAF with MDP and $10^{-14}$ M PAF with LPS. the effect of PAF was also tested in silica, toxic respirable dust, -added AM cultures as well as in the cultures containing bacterial compounds. Although silica did not stimulate the IL-1 activity, PAF could enhance IL-1 activity by 2 fold above the value of the silica-treated AM cultures with the peak response at $10^{-12}$ M PAF. Optimal enhancement of IL-1 activity occured when MDP and PAF were present together at the initiation of the 24 hr AM cultures. Additionaly, the biologically inactive precursor/metabolite of PAF, lyso-PAF failed to induce enhancement of IL-1 activity. When the specific, but structurally different PAF receptor antagonists, BN 52021($10^{-5}$ M) and CV 3988($10^{-5}$ M) was treated 15 min before addition of PAF($10^{-8}$ M) and MDP$(10\;{\mu}g/ml)$ to the AM cultures, it markedly inhibited the enhancement of IL-1 activity induced by PAF. The effects of these PAF antagonists were also observed in LPS$(10\;{\mu}g/ml)$-stimulated cells. Collectively, these data suggest that PAF enhances IL-1 activity by interaction with a specific receptor.

  • 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.

  • Objective: To explore the influence of different ways of blood transfusion on the expression levels of interleukins (IL) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) inperi-operative patients with esophageal cancer. Materials and Methods: A total of 80 patients with esophageal cancer who underwent radical operations were selected as study patients and randomly divided into an observation group (treated with autologous blood transfusion) and control group (with homologous blood transfusion). Changes of intra-operative indexes and peri-operative blood indexes, from hemoglobin (Hb) and hematocrit value (Hct), to levels of inflammatory factors like interleukins-6 (IL-6), IL-8, IL-10 and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) were compared. Results: Operations for patients in both groups were successfully conducted, and no significant differences in mean surgical duration and intra-operative hemorrhage volume, fluid infusion volume and blood transfusion volume were detected (p>0.05). Compared with values before surgery, Hb and Hct levels decreased significantly while white blood cell count (WBC) increased 1, 5 and 7 d after operation (p<0.05, p<0.01). In addition, WBC was apparently higher in observation group than in control group 5 and 7 d after operation (p<0.01). Compared with before surgery, in the observation group, levels of IL-6, IL-8 and IL-10 had no significant differences after operation (P>0.05), but TNF-${\alpha}$ level increased y (p<0.01), whereas in control group, IL-6 level had no significant difference (p>0.05), IL-8 level decreased obviously (p<0.05), IL-10 level increased markedly first and then decreased gradually as time passed but its level remained elevated (p<0.01), and TNF-${\alpha}$ level increased first and then decreased, and there was no significant difference 7 d after operation (p>0.05). Conclusions: Decreased IL-8 and increased IL-10 levels are two important reasons for immunosuppression after homologous blood transfusion, whereas autologous blood transfusion can alleviate this while increasing the TNF-${\alpha}$ level, which also has potential to improve anti-tumor immunity in the human body.
