  • The relationship between pain stimulation and the blood glucose level was studied in ICR mice. We examined the possible change of the blood glucose level after the pain stimulation induced by acetic acid injected intraperitoneally (i.p.),, formalin injected subcutaneously (s.c.) into the hind paw, or substance P (SP), glutamate, and proinflammatory cytokines (TNF-${\alpha}$ and IFN-${\gamma}$) injected intrathecally (i.t.). We found in the present study that acetic acid, formalin, SP, TNF-${\alpha}$, and IFN-${\gamma}$ increased the blood glucose level. The blood glucose level reached at maximal state 30 min and returned to normal level 2 h after the pain stimulation in a fasting group. Furthermore, acetic acid, formalin, SP, TNF-${\alpha}$, and IFN-${\gamma}$ caused the elevation of the blood glucose level in D-glucose-fed group only in an additive manner. However, i.t. injection of glutamate did not alter the blood glucose level in a fasting group. In contrast, i.t. injection of glutamate enhanced the blood glucose level in the D-glucose-fed group. Our results suggest that the blood glucose level appears to be differentially regulated by various pain stimulation induced by acetic acid, formalin, SP, glutamate, and pro-inflammatory cytokines.

  • Objectives : The aim was to identify the inhibitory effects of Liriopis Tuber on bleomycin-induced lung fibrosis by analysing the changes of imflammatory cell cytokines and SHI(Semiquantitative Histological Index), Materials and Methods : In this study fibrosis prone C57BL/6J mice were used. Control group was treated with blomycin(0.06mg/0.1 ml) by IT(intratracheal) instillation which is a popular method of inducing lung fibrosis and sample group took Liriopis Tuber water extract(38.0mg/10g body weight) orally for 14 days after IT instillation of blomycin. We measured the total and differential count of WBC, $IFN-{\gamma}$ & IL-4 in mice BALF and SHI(Semiquantitative Histological Index) from lung tissues of mice. BALF and lung tissues of mice were taken 14 days after IT instillation of blomycin. Results : In sample group total WBC count, proportion of neutrophil, SHI and IL-4 significantly(p<0.05) decreased, proportion of macrophage significantly(p<0.05) increased and proportion of lymphocyte, $IFN-{\gamma}$ did not decrease significantly. Conclusions : This study suggests that Liriopis Tuber has an inhibitory effects of pulmonary fibrosis by attenuation of inflammation and Th2 immune response. To determine whether this herbal medicine contribute to cure and prophylaxis of pulmonary fibrosis, further studies on the role of $IFN-{\gamma}$ relating to fibrosis are required.

  • Objective : This study was performed to evaluate the effect of Forsythiae Fructus (FF) ethanol extract on inflammatory cytokine production and its underlying mechanisms in mouse macrophages. Methods : Peritoneal macrophages from thioglycollate medium-injected mice were cultured and stimulated with lipopolysaccharide(LPS) or LPS/interferon(IFN)-${\gamma}$ for cytokine measurement and cellular signaling molecule analysis. Results : FF ethanol extract decreased the levels of secreted tumor necrosis factor(TNF)-${\alpha}$ and interleukin(IL)-6 in IFN-${\gamma}$/LPS-stimulated cells in a concentration-dependent manner. FF extract reduced IFN-${\gamma}$/LPS-induced STAT1 phosphorylation and LPS-induced p38 and JNK activation, but not ERK1/2 activity. The extract also inhibited LPS-induced $I{\kappa}B{\alpha}$ degradation through suppression of $I{\kappa}B{\alpha}$ kinase. Conclusions : These results suggest that FF ethanol extract affects the production of TNF-${\alpha}$ and IL-6 through inhibition of activation of STAT-1, $I{\kappa}B{\alpha}$, p38, and JNK.

  • The present study aimed to show that pro-inflammatory cytokines [tumor necrosis factor (TNF)-${\alpha}$, interferon (IFN)-${\gamma}$, and interleukin (IL)-$1{\beta}$] synergistically induce the production of nitric oxide (NO) production in mouse mesangial cells, which play an important role in inflammatory glomerular injury. We also found that co-treatment with cytokines at low doses (TNF-${\alpha}$; 5 ng/ml, IFN-${\gamma}$; 5 ng/ml, and IL-$1{\beta}$; 1.25 U/ml) synergistically induced NO production, whereas treatment with each cytokine alone did not increase NO production at doses up to 100 ng/ml or 50 U/ml. Silymarin, a polyphenolic flavonoid isolated from milk thistle (Silybum marianum), attenuates cytokine mixture (TNF-${\alpha}$, IFN-${\gamma}$, and IL-$1{\beta}$)-induced NO production. Western blot and RT-PCR analyses showed that silymarin inhibits inducible nitric oxide synthase (iNOS) expression in a dose-dependent manner. Silymarin also inhibited extracellular signal-regulated protein kinase-1 and -2 (ERK1/2) phosphorylation. Collectively, we have demonstrated that silymarin inhibits NO production in mouse mesangial cells, and may act as a useful anti-inflammatory agent.

  • The immunomodulatory effect of a new herbal preparation, HemoHIM, on the recovery from leukopenia induced by cyclophosphamide treatment was investigated. The HemoHIM was made up with an addition of the ethanol-insoluble fraction to the total water extract of Angelica Radix, Cnidii Rhizoma and Paeonia Radix. Daily oral administration of 100 mg/kg BW or 500 mg/kg BW HemoHIM accelerated the recovery from cyclophosphamide-induced leukopenia. HemoHIM increased the number of leukocytes and lymphocytes in the peripheral blood when compared with the cyclophosphamide-treated control. Moreover, the suppressed natural killer (NK) cell activity and interferon $(IFN)-{\gamma}$ secretion in the cyclophosphamide-treated mice were restored by the administration of HemoHIM. HemoHIM significantly reduced the abnormally heightened ratio of interleukin $(IL)-4/IFN-{\gamma}$ and immunoglobulin (Ig)E/IgG2a in the cyclophosphamide-treated mice. These results suggest that HemoHIM accelerates the recovery from leukopenia and alleviates the imbalanced T helper (Th)l/Th2 responses in the cyclophosphamide-treated mice. Additionally, HemoHIM was found to stimulate normal splenocytes to secrete not only Thl type cytokines such as $IFN-{\gamma}$ and IL-2, but also Th2 type cytokine IL-4. In conclusion, our results show that HemoHIM certainly has an influence on the balanced recovery of immune cells and the activation of their activities in the cyclophosphamide-treated mice.

  • Objective : To investigate the effects of Pyeongwi-san-gamibang on atopic dermatitis, this study measured TEWL(transepidermal water loss), observed scratching behaviors and checked levels of Total IgE, IL-4, IFN-${\gamma}$ and conducted skin biopsy on NC/Nga mice with atopic dermatitis. Methods : NC/Nga mice were challenged with DNCB during 5 weeks to develop atopic dermatitis-like skin lesions. The NC/Nga mice with atopic dermatitis were divided into three groups of control group, PW-d, PW-e group. Once a day for 22 days, Pyeongwi-san-GamiBang extract with water was administered for the PW-d group and the extract with 80% ethanol was administered for PW-e group compared with saline solution for control group. During drug administration, sensitization by DNCB had lasted for three times per week. Results : 1. TEWL had no statistical difference among 3 groups. 2. The scratching behaviors had no statistical difference among 3 groups. 3. The levels of Total IgE in PW-d, PW-e group had a statistically significantly higher than that of the control group although difference between the control group and the PW-d, PW-e group were similar. 4. The level of IL-4 had no statistical difference among 3 groups. 5. The level of IFN-${\gamma}$ had no statistical difference among 3 groups. 6. As the observation of toluidine blue stained lesion, both PW-d and PW-e group had lower level of histamine releasement compared with the control group. Conclusion : Result based on these experiments, Pyeongwi-san-GamiBang on atopic dermatitis-like skin inflammation in NC/Nga mice is not effective. But, as the study showed significantly individual differece, we need to repeat these study after supplementing the object number and modified indicator of clinical severity.

  • 치조골흡수는 만성치주질환의 전형적인 증상이다. 골흡수에 작용하는 여러 요인들 중에서도, 특히 최근에 들어서 몇몇 cytokine들에 대한 관심이 높아지고 있는데, interleukin-1(IL-1), tumor necrosis factor(TNF) 및 interleukin-6(IL-6) 등이 치주질환의 진행과정에서 중요한 치조골흡수요인으로 제안되고 있다. 본 연구의 목적은 신생쥐의 골조직 배양실험을 통해서 recombinant human $interleukin-1{\beta}$ ($rHuIL-1{\beta}$), recombinant human tumor necrosis $factor-{\alpha}$($rHuTNF-{\alpha}$) 및 recombinant human interleukin-6(rHuIL-6) 의 골흡수 유도효과를 알아보고, cyclooxygenase 억제제인 indomethacin과 recombinant murine $interferon-{\gamma}$($rMurIFN-{\gamma}$)가 이들 cytokine의 골흡수 유도능력에 미치는 영향을 알아봄으로써 이들 cytokine의 작용기구에 대해서 알아보고자 하는데 있다. 생후 1-2일된 쥐에게 $1{\mu}Ci^{45}CaCl_2$를 피하주사하고 4일 후에 쥐를 희생시켜 $^{45}Ca$ 로 표지된 두개골을 얻어 24시간 전배양 후, 각 cytokine ($rHuIL-1{\beta}$, $rHuTNF-{\alpha}$ 및 rHuIL-6)과 cytokine 및 첨가약제 (indomethacin 및 $rMurIFN-{\gamma}$)가 함유된 배지로 교환하여 48시간 배양한다. 골흡수 유도효과는 두개골에서 48시간의 배양 중 유리되는 $^{45}Ca$의 방사능 정도로 평가하였다. 본 연구를 통해 다음과 같은 결과를 얻었다. 1. $rHuIL-1{\beta}$ ($10^{-12}-10^{-9}M$) 및 $rHuTNF-{\alpha}$ ($10^{-10}-10^{-8}M$)는 농도변화에 따르는 골흡수 유도효과를 보였으나 , rHuIL-6 ($10^{-10}-10^{-8}M$)는 유의할 만한 효과를 보이지 않았다. 2. Indomethacin ($10^{-6}M$)은 $rHuIL-1{\beta}$$rHuTNF-{\alpha}$의 골흡수 유도작용에 유의할 만한 억제효과를 나타내지 않았다. 3. $rMurIFN-{\gamma}$ (1000 U/ml) 은 $rHuIL-1{\beta}$$rHuTNF-{\alpha}$의 골흡수 유도작용에 유의한 억제효과를 나타내었다. 본연구를 통해 치주질환 환자의 치주조직에서 검출되는 $IL-1{\beta}$$TNF-{\alpha}$가 치조골 흡수에 중요한 역할을 할 것으로 생각된다.

  • Objectives : In this study, we investigated the immunomodulatory and antioxidant effect of MOK, a pharmacopuncture medicine, in concanavalin A (Con A)-stimulated mouse splenocytes. Methods : Primary splenocytes were isolated from ICR mice. The splenocytes were treated with MOK extract (1.25, 2.5, 5, 10, and 20 mg/mL) for 30 min and then stimulated with Con A (200 ng/mL) for the indicated times. Cell viability of the splenocytes was measured using an MTT assay. The mRNA expression of Th1/Th2 cytokines ($IFN-{\gamma}$, IL-4, IL-10, and Foxp3) and antioxidant enzymes (HO-1 and MnSOD) was measured by RT-PCR. Results : Addition of MOK extract at 2.5, 5, and 10 mg/mL in Con A-stimulated splenocytes significantly decreased the production of $IFN-{\gamma}$ and significantly increased the expression of IL-4, IL-10, and Foxp3 mRNA. MOK extract also increased the mRNA expression of HO-1 and MnSOD in splenocytes. Conclusion : MOK extract modulated the Th1/Th2 immune response via the regulation of cytokine levels in splenocytes and exerted an antioxidant effect via the upregulation of antioxidant proteins.
