CSH/HeJ 마우스에 Acanaamoeba culbertsoni영양형 $3{\;}{\times}{\;}10^5$개를 비강으로 접종하 여 실험적 아메바성 수막뇌염을 일으킬 때 숙주의 방어기작에 대식세포가 미치는 영향을 알아 보았다. 대식세포 억제제인 silica를 마우스 복강 내로 투여한 경우의 사망율이 60.6%로 아메바만을 접종한 마우스의 사망율이 10.0%와 비하여 큰 차이를 보였으며 열처리하여 죽인 Toxoplasma gondii tachyzoites의 in vitro탐식능 관찰에서 기능을 억제시킨 대식세포의 탐식능이 3% 이하로써 아메바에 대한 복강대식세포의 기능의 저하로 인한 수막뇌염의 증가를 관찰하였다. A. culbertsoni에 대한 대식세포의 살해활동의 in vitro 실험에서 silica투여한 실험군의 복강대식세포의 뚜렷한 기능 저하를 관찰하였고, 효소표지 면역 검사법(ELISU)을 이용한 마우스 혈청 내의 $interleukin-1{\beta}(IL-1{\beta})$의 흡광도는 아메바 접종군과 생리식염수 투여군보다 silica투여를 수반한 실험군이 현저하게 낮게 나타나 대식세포가 억제되었을 때 실험적 수막뇌염이 증가함을 알 수 있었다. 결과적으로 대식세포가 A. culbertsoni 감염에 대한 숙주의 방어작용에 중요한 역할을 하는 것으로 생각된다.

Purpose : This study was carried out to investigate the effects of Gagamdokhwalgisang-Tang on the morphometric changes of femur, and on the hormones and cytokines associated with bone metabolism in overiectomized rats. Methods : Twenty-four female Sprague-Dawley rats were divided into sham operated group(normal) ovariectomized group(control), and treated with extract of GD group(treated). Each group was evaluated the changes of body weight at 0, 3, 6, 8 weeks after ovariectomy. Morphometric analysis(femur weight, femur/body weight ratio, femur ash weight femur ash/body weight ratio cross sectional area of compact bone and concellous bone of femur) and histopathological examination were performed at 8 weeks after ovariectomy. Estrogen, Alkaline Phosphatase(ALP) and cytokine(Tumor necrosis $factor-{\alpha}$, $Interleukin-l{\beta}$, Inerleukin-6) assay were performed at 8 weeks after ovariectomy. Results : 1. The body weight of control and treated group was significantly increased(p<<0.001) compared with the normal group at 8 weeks. 2. The femur weight and femur/body weight ratio of treated group were significantly increased(p<<0.05, p<<0.01) compared with the control group at 8 weeks. 3. The femur ash weight showed no significantly different changes, but femur ash/body weight ratio of treated group was significantly increased(p<<0.05) compared with the control group at 8 weeks. 4. In the cross sectional area of cancellous bone of femoral body, the treated group was significantly increased(p<<0.001) compared with the control group at 8 weeks. 5. The serum estrogen level of treated group showed no significantly different changes compared with the control group at 8 weeks. 6. The serum ALP activity of treated group was significantly decreased(p<<0.01) compared with the control group at 8 weeks. 7. The serum Tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ level of treated group was significantly decreased(p<<0.05) compared with the control group at 8 weeks. 8. The serum $Interleukin-l{\beta}(IL-1{\beta})$ level of treated group was significantly decreased(n<<0.001) compared with the control group at 8 weeks. 9. The serum Interleukin-6(IL-6) level of treated group was significantly decreased(P<<0.01)compared with the control group at 8 weeks. Conclusion : These results indicate that GD inhibits bone resorption in ovariectomized rats. And the major inhibitory mechanism may be related to the inhibitory effects of GD on the secretion of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 in the pathogenesis of osteoporosis in estrogen deficient rats.

목적 - Inflammatory cytokine으로 알려진 interleukin 1$\beta$, tumor necrosis factor $\alpha$는 치수 및 치근단질환에서 주요한 역할을 하며, 골흡수를 자극하고 골형성을 방해하는 것으로 알려져 왔다. 이들 cytokine은 주로 단핵세포/대식세포가 형성하는 것으로 알려져 왔으나 최근 연구에 의하면, PMN도 또한 이 런 cytokine들을 형성할 수 있다는 것이 보고되었다. 오랫동안 염증반응이나 면역반응에서 PMN의 역할이 주로 포식작용 을 통해 병원균을 제거하는 것이라고만 생각되어져 왔던 것을 생각하면, 새로운 발견이라 할 수 있다. 또, PMN은 IL-1ra도 생성하는 것으로 보고되었는데, IL-1ra란 IL-1의 생물학적 작용을 방해하는 인자이므로, IL-1과 밀접한 관련을 가지는 질환의 발전에 있어서 IL-1과 IL-1ra의 balance가 매우 중요한 역할을 할 것으로 생각된다 즉, IL-1ra는 IL-1$\beta$의 proinflammatory effect를 제한할 수 있는 negative feedback mechanism이라고 할 수 있다. 이 연구의 목적은 치수 및 치근단 조직의 감염에 있어서 주요 원인균인 Porphyromonas endodontalis의 LPS가 PMN의 IL-1$\beta$, TNF-$\alpha$, IL-1ra생성에 미치는 영향을 단백질과 mRNA 수준에서 관찰하는 것이다. 잘 알려진 non-oral bacterium인 E. coli의 LPS를 positive control로 사용하였으며, IL-1ra가 IL-1$\beta$의 생물학적 작용을 방해하는 작용을 관찰하기 위해, IL-1의 biological assay도 시행하였다. 방법 - P. endodontalis ATCC 35406을 혐기성 조건에서 배양하고, hot phenol-water extraction의 방법으로 LPS를 추출(crude LPS)한 후, 제조회사로부터 구입한 E. coli의 crude LPS와 함께 정제하였다. 건강한 자원자들을 대상으로 말초혈액을 채취한 후 dextran sedimentaion을 거쳐 Lymphoprep을 이용하여 PMN층을 분리하였다. 얻어진 세포들은 RPMI 1640 (supplemented with fetal bovine serum antibiotics)에 5$\times$$10^{6}$cells/ml이 되도록 resuspend시킨 후 각기 다른 농도 (0, 0.01, 0.1, 1 and 10$\mu$g/ml)의 LPS를 처리하여, 각기 다른 시간(Northern blot : 1, 2, 4시간 ELISA : 2, 6, 12, 18시간)동안 37$^{\circ}C$ in 5% $CO_2$ 의 조건으로 배양하였다. 상층액은 -7$0^{\circ}C$에 보관하였다가 추후에 ELISA를 이용한 단백질 농도 측정과 IL-1 biological assay에 사용되어졌으며, 배양된 세포로부터 RNA를 추출하여 Northern hybridization을 통해 mRNA expression을 관찰하였다.

Typha orientalis' stem (TOS) is traditionally used as an herbal medicine for difficulty in urination, galactophoritis purulenta, whooping cough, and allergic dermatitis. However, its effect in experimental models remains unknown. Here, we report the effect of TOS on the phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187-induced inflammatory cytokine production and extracellular signal-regulated kinase (ERK) activation in the human mast cell line, HMC-1. TOS inhibited PMA plus A23187-induced cytokines such as tumor necrosis factor-alpha (TNF-$\alpha$) and interleukin (IL)-6. Maximal inhibition rate of TNF-$\alpha$ and IL-6 production by TOS (1 mg/ml) was about 44.02%, and 45.20%, respectively (P < 0.05). In addition, TOS inhibited the expression of TNF-$\alpha$ and IL-6 mRNA under the same condition. Moreover, TOS partially blocked PMA plus A23187-induced ERK phosphorylation. These results suggested TOS could inhibit the cytokine production through blocking of ERK activity.

Total spleen lymphocytes, lymphocyte proliferation, tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and interleukin-10 (IL-10) in spleen lymphocyte culture were studied in malnourished Wistar rats fed with goat milk yoghurt. Malnourished rats were created by using standard feed restriction as much as 50% of normal rats for 21 d. Goat milk yoghurt containing three types of microorganism e.g., Lactobacillus acidophilus, Sterptococcus thermophilus and Bifidobacterium longum derived from Lacto-B culture in powder form. After 21 d, the rats continued to receive restricted feeding and supplemented with goat milk yoghurt for 7 d. Total splenocytes were counted by hemocytometer. Splenocytes proliferation was expressed as stimulation index, whereas the TNF-${\alpha}$ and IL-10 of spleen lymphocyte culture were measured by ELISA technique. The total number of splenocytes and stimulation index of splenocytes in moderate malnourished and normal rats supplemented with goat milk yoghurt was not significantly different. The level of TNF-${\alpha}$ in the rat supplemented with goat milk yoghurt was lower (p<0.05) than the control group, whereas the level of IL-10 in the rat supplemented with goat milk yoghurt was higher (p<0.05) than the control group. In conclusion, goat milk yoghurt supplementation in malnourished rats could decrease TNF-${\alpha}$ as a representation of the pro-inflammatory cytokine, while it increases IL-10 as a representation of the anti-inflammatory cytokine.

Purpose: The purpose of this study was to investigate the anti-inflammatory effects of the water extract of Omisodokeum (OMSDE) on peritoneal macrophages, Methods: To verify the anti-inflammatory mechanism of OMSDE, the activation of nuclear $factor-{\kappa}B$ $(NF-{\kappa}B)$ and the phosphorylation of MAPK were examined. Results: The extract of OMSDE suppressed the production of LPS-induced nitric oxide (NO), tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-6 and IL-12 in the macrophages. OMSDE inhibited the degradation of inhibitory ${\kappa}B-{\alpha}$ $(I{\kappa}B-{\alpha})$ and it suppressed the activation of extracellular signal-regulated kinase (ERK 1/2) but didn't inhibit c-Jun N-terminal kinase (JNK) and p38, indicating that OMSDE may inhibit the pro-inflammatory cytokine production process by inhibiting the activation of $NF-{\kappa}B$ and ERK 1/2. Furthermore, OMSDE inhibited the production of interferon $(IFN)-{\beta}$ but didn't inhibit of $IFN-{\alpha}$ in the LPS-stimulated macrophages through the down-regulation of interferon regulatory factor (IRF)-1 and IRF-7. The Oral administration of OMSDE inhibited LPS-induced endotoxin shock and the production of $TNF-{\alpha}$ in serum but didn't inhibit of $IL-1{\beta}$ and IL-6. Conclusion: These results suggest that OMSDE may be effective in the prevention and treatment of inflammatory diseases.

Objective : Major depression is known to have immunologic dysfunctions, the recent studies revealed that cytokines including IL-6 and IL-$1{\beta}$ were increased in patients with major depression. Since molecular genetic methods have been progressed, this study was to investigate the relationship between major depression and immunologic aspects by analyzing polymorphism of IL-10 gene. Method : 92 patients with major depression were included and data of 146 normal controls obtained from the Catholic Hemopoietic Stem Cell Information Bank of Korea were used in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaction, and digested by Mae III After that procedure, we obtained and assessed RFLP of two alleles, IL-10T and IL-10C. All data were analyzed by ${\chi}^2$ test. Results : 1) There were no significant difference in genotype frequencies of $IL-10^*T/T$, $IL-10^*T/C$, and $IL-10^*C/C$ between major depression patients group and control group. 2) There were no significant difference in allelic frequencies of $IL-10^*T$ and $IL-10^*C$ between major depression patients group and control group. Conclusion : We did not verified the differences in frequencies of $IL-10^*T/^*IL-10^*C$ gene between the major depression patients group and control group, respectively. But the results of this study do not declare that the IL-10 gene has no association with major depression. We do suggest that further systematic studies including various clinical variables should be conducted.

This study was done to investigate effects of antioxidant supplementation on phytohemagglutinin (PHA) -stimulated interleukin-2 (IL-2) production by peripheral blood mononuclear cells (PBMCs) in elderly women. This study was designed as a placebo-controlled, single-blinded, randomized intervention trial. Twenty four elderly women aged over 60 years, visitings social welfare center in Seoul were divided into 3 groups, placebo (n = 8), vitamin C supplemented (n = 8) , and vitamin E supplemented (n = 8) groups. Experimental groups were given either 1000mg of L-ascorbic acid or 400 ill of d- $\alpha$-tocopherol for 4 weeks. There was no significant difference in antioxidant vitamins intakes and their plasma levels among pre-intervention groups. Plasma vitamin C or E levels was significantly increased after vitamin C or E sup-plementations. The increases of plasma thiobarbituric acid-reactive substance (TBARS) levels in the placebo group were significantly higher than those of the supplemented 2 groups. There were no significant differences in the changes of plasma IL-2 level between pre- and post-intervention among the 3 groups. However there was a significant increase in PHA­stimulated IL-2 production by PBMCs after 4-week vitamin E or vitamin C supplementation. Particularly, vitamin E supplemented group showed a higher PHA-stimulated IL-2 production than vitamin C supplemented group. These results indicate that vitamin E or vitamin C supplementation might enhance mitogen-stimulated cytokine production by immune cells, which could be one of the factors to improve health status in the elderly.

Capsaicin is the active ingredient in chili pepper and has an inhibitory effect on Helicobacter pylori growth and $NF-{\kappa}B$ activation. The present study examined the effect of capsaicin on interleukin (IL)-8 production by H. pylori ATCC 43504-infected MKN-45 cells, a gastric epithelial cell line. The viability of the MKN-45 cells treated with capsaicin at 0, 50, 100, 250, and $500\;{\mu}M$ was 99, 98, 99, 99, and 85%, respectively. A capsaicin concentration as low as $50\;{\mu}M$ significantly inhibited the IL-8 production induced by H. pylori ATCC 43504 infection (43.2% of control) during 24 h of incubation. However, low concentrations of capsaicin $(50\;and\;100{\mu}M)$ did not significantly inhibit the IL-8 production by $TNF-{\alpha}-$ or PMA-treated MKN-45 cells. Therefore, the overall inhibitory effect of capsaicin on H. pylori ATCC 43504 was the sum of H. pylori ATCC 43504 growth inhibition, host cell survival, and $NF-{\kappa}B$ signal cascade inhibition.
