  • Objective: With the onset of stroke, white blood cells release several proinflammatory cytokines, including interleukin (IL)-6, IL-10, and tumor necrosis factor $(TNF)-{\alpha}$. It has been proven in previous studies that the release of these cytokines is related to the extent of damage to the brain and to overall prognosis. However, no studies have yet been performed to determine the connection with IL-6 and IL-10. Thus, this study is performed to see whether polymorphisms of IL-6, IL-10, and $TNF-{\alpha}$ genes that show increased serum concentration with the onset of stroke are related to stroke attack in Koreans. Methods : Peripheral blood samples derived from patients with stroke (n=100) and healthy controls (n=100) were taken under informed consent. In subjects with stroke, blood samples were obtained within 24 hours of stroke onset. Genomic DNA was isolated using the Wizard DNA Purification Kit (Promega, Madison, WI). Results : 1. Subjects with Heterozygote (GA) and Homozygote (AA) $TNF-{\alpha}$ gene types showed 2.433 and 20.457 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (GG) $TNF-{\alpha}$ gene type. The data was still statistically significant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 2. Subjects with Homozygote (CC) IL-6 gene type showed 182.033 times higher risk of being attacked by stroke, compared to subjects with wild type (GG) IL-6 genes. This data was statistically insignificant (p=0.700). The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 3. Subjects with Heterozygote (GA) and Homozygote (GG) IL-10 gene types showed 8.785 and 3.303 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (AA) IL-10 genes. The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. Conclusion : Our results suggest that the investigated $TNF-{\alpha}$ and IL-10 gene polymorphisms play an important role in stroke attack, but IL-6 gene polymorphism has not been found to associated with stroke.

  • Objectives and methods : Previous mechanistic studies suggest the cyclooxygenase-2 (COX-2) inhibitors represent the good candidates against tumor progression. MeOH extract of the stem barks of Euonymus alatus induced the strong inhibition of COX-2. A phenolic compound responsible for the anti- COX-2 known to involve in tumor adhesion and invasion has been studied through the methanol extracts. The compound, rosmarinic acid (ROS-A) was an ester of caffeic acid and 3,4-dihydroxyphenyllactic acid. ROS-A showed a strong inhibitory effect of COX-2 activity in a concentration-dependent manner. Then we have measured the IL-1${\beta}$, IL-6 and TNF-${\alpha}$ production related the immune regulation, induction of inflammatory related genes. Results and Conclusions :Hep3B cells produce proinflammatory cytokines of IL-1${\beta}$, IL-6 and TNF-${\alpha}$ while ROS A inhibited the cytokines production. Since IL-1${\beta}$, IL-6 and TNF-${\alpha}$ need the transcription factors such as nuclear factor- ${\kappa}$B (NF-${\kappa}$B) and activated protein-1 (AP-1), we measured the transcription factors. ROS-A inhibited the activation of p65, p50, c-Rel subunits of NF-${\kappa}$B and AP-1 transcription factors. These findings indicate that ROS A from the stem bark of E. alatus inhibits proliferation in metastatic cancer cells. It was suggested that stem barks of E. alatus could be suitable for anti-cancer drugs.

  • To investigate the capacity of anti-inflammatory cytokines and biological response modifiers (BRMs) to induce IL-$1{\beta}$, IL-6, TNF-${\alpha}$ gene overexpression from mouse macrophages, we isolated the resident peritoneal macrophages from BALB/c mouse (8 week old) and incubated for 6 h with lipopolysaccaride (LPS) and Moschus moschiferus (MOMS) extracts. Analysis of inflammatory cytokines gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. 1. LPS and MOMS extract treatments resulted in a significant decrease in IL-$1{\beta}$, IL-6, TNF-${\alpha}$ mRNA expression level compared with the LPS treatment. 2. Among four sample of MOMS, Inhibitory effects of MOMS-A and MOMS-D for inflammatory cytokines gene expression were to be fine compared with the MOMS-Band MOMS-C. According to the above data, Because the anti- tumoral and anti-inflammatory response activities of macrophage are known to be dependent on the production of inflammatory cytokines (IL-$1{\beta}$, IL-6, TNF-${\alpha}$) by macrophages, we suggest that evaluations of BRM for the reduction of inflammatory cytokines production by macrophages are important for clinical application.

  • Background: This present study was conducted to evaluate the anti-inflammatory and immune regulatory effects of Aucklandia lappa Decne (AL). Methods and Results: We measured cytotoxicity, nitric oxide (NO) content, mRNA expression (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$), protein expression (iNOS, COX-2, and $I{\kappa}B$) and phagocytic activity in RAW264.7 cells. Male BALB/c mice were fed 100 mg/kg AL (Aucklandia lappa Decneon 70% ethanol extract) and 250 mg/kg AL for 4 weeks; thereafter, we observed B/T or $CD4^+/CD8^+$ lymphocyte subpopulation change, and expression patterns of $CD4^+$ and $CD8^+$ lymphocytes by immunohistochemical staining in mouse splenocytes and/or thymocytes. To determine the experimental concentration of AL, cell viability was measured by MTT assay and tested at $12.5{\mu}g/m{\ell}$ or less. AL inhibited the levels of NO, lymphokine production (IL-$1{\beta}$, and TNF-${\alpha}$), and mRNA (iNOS, IL-1${\alpha}$, IL-$1{\beta}$, and TNF-${\alpha}$) and protein (iNOS, and COX-2) expression. Additionally, the levels of $I{\kappa}B$, phagocytic activity, and splenic and thymic T lymphocytes, especially $T_H$ and $T_C$ cells were significantly increased in AL administered mice. The immuno-reactive density of $CD4^+$ and $CD8^+$ lymphocytes was stronger in AL groups than in the normal group. AL stimulated NO, iNOS, and COX-2, and regulated IL-1${\alpha}$, IL-$1{\beta}$, TNF-${\alpha}$, and $I{\kappa}B$ in macrophages treated with LPS (lipopolysaccharide). In addition, AL increased the phagocytic activity of macrophages and the immunity of mouse T ($T_H$, and $T_C$) cells. Conclusions: These results suggested that AL might show anti-inflammatory activity via the suppression of various inflammatory markers and immuno-regulatory activity.

  • Although monoculture methods have been remarkably useful due to their simplicity, they have serious limitation because of the different types of cells communication with each other in many physiological situations. We demonstrated levels of markers of endothelial dysfunction such as tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and interleukin-1$\beta$ (IL-1$\beta$) as well as stimulation of receptor of advanced glycation endproducts (AGEs) on monoand co-culture system such as only monocyte (THP-1) cultivation system, only endothelial cell (HUVEC) cultivation system, and co-cultivation system of THP-1 and HUVEC. The mRNA levels of TNF-$\alpha$ and IL-1$\beta$ on HUVEC increased by the co-culture with monocyte after 4 hr at 100 ${\mu}g/mL$ glyceraldehyde-AGE. The secreted protein contents into medium of TNF-$\alpha$ and IL-1$\beta$ increased after 8 hr approximately 2~2.5 times compared to mono-cultivation. In contrast, the mRNA level of receptor of AGE (RAGE) was relatively insensitive on the co-culture system. The mediators by which monocytes activate endothelial cell have not been fully elucidated. In this study we confirmed production of soluble cytokines such as TNF-$\alpha$ and IL-1$\beta$ by monocytes. Use of monocyte conditioned medium, which contains both cytokines, can activate endothelial cell.

  • Objectives : The present study investigated inflammatory effect of Rheum undulatum L. in lipopolysaccharide-exposed rats and Raw 264.7 cells. Methods : Male rats weighting $185.39{\pm}8.21g$ fed basal diet for 1 week and 32 rats were divided into a control group and 3 experimental groups. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1time/1day) for 6 weeks. And we fed basal diet and administered an extract of Rheum undulatum L.(100 mg/kg, 200 mg/kg, 300 mg/kg, 1time/1day) to each experimental group of rats. We measured the plasma concentration of $IL-1{\beta}$($interleukin-1{\beta}$), IL-6 and $TNF-{\alpha}$(tumor necrosis $factor-{\alpha}$), liver cytokines, Raw 264.7 macrophages cytokines. Results : The plasma concentration of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ peaked at 5h(hour) after LPS(lipopolysaccharides) injection, and the values of the Rheum undulatum L. extract groups were lower than those of the control group. In the increment of these cytokines concentration at 2h and 5h after LPS injection, the Rheum undulatum L. groups were lower than that of control group. The plasma concentration of IL-10 peaked at 5h after LPS injection, and the values of the Rheum undulatum L. extract groups were higher than those of the control group. In the increment of this cytokine concentration at 2h and 5h after LPS injection, the Rheum undulatum L. groups were higher than that of control group. Liver cytokines measurement was done at 5h after LPS injection. The concentration of liver $IL-1{\beta}$ and IL-6 in the Rheum undulatum L. groups was lower than that of the control group. The concentrations of liver $TNF-{\alpha}$, and IL-10 showed no significant differences among all the treatment groups. In the studies of lipopolysaccharide-exposed Raw 264.7 cells, the concentration of $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ in the lipopolysaccharide-exposed cells groups was higher than that of control group(normal group), and in the lipopolysaccharide-exposed cells groups, these values showed a tendency to decrease in the Rheum undulatum L. groups. The concentration of IL-10 in the lipopolysaccharide-exposed cells groups was higher than that of control group(normal group), and in the lipopolysaccharide-exposed cells groups, the values showed a tendency to increase in the Rheum undulatum L. groups. Conclusions : These results indicate that the Rheum undulatum L. extracts have an functional material for inflammatory activities.

  • Purpose : 자하거(Hominis Placenta; HP)는 건강한 사람의 태반을 홍제(烘製)하여 건조한 것으로 한의학에서는 기혈(氣血)을 대보(大補)하고 신정(腎精)을 보익(補益)시켜 구병(久病)으로 인한 신체허약(身體虛弱)이나 혹은 체질허약(體質虛弱)과 혈기부족(氣血不足) 및 신허정휴(腎虛精虧) 등 등(證)을 치료(治療)하는데 단미(單味) 또는 복방(複方)에 배오(配伍)하여 쓰여왔다. 또한 자하거는 면역학적으로 골대사 활성이 있는 것으로 알려져 있어 본 연구에서는 자하거의 항골다공증 활성을 분자세포생물학적으로 검정하고자 하였다. Methods : Osteoblast cells에서 자하거가 COX-2 mRNA의 발현과 $PGE_2$ 생합성을 억제시키는지를 관찰하기 위해 먼저 TNF-${\alpha}$, IL-${\beta}$ 와 IL-6를 처리한 후 $PGE_2$의 생합성과 더불어 COX-2 mRNA의 발현을 확인하였다. 그 후 TGF-${\beta}$, 자하거(紫河車)와 이 둘의 조합인 자하거+TGF-${\beta}$가 COX-2 mRNA 발현과 $PGE_2$ 생합성을 저해시키는지 관찰하였다. 또한 자하거가 IL-1${\beta}$로 유발된 흰쥐의 과칼슘혈증을 감소시키는지를 확인하였다. Results : IL-6, IL-1${\beta}$와 TNF-${\alpha}$를 동시에 처리하면 이것을 단독으로 처리한 것과 비교해 볼 때 $PGE_2$의 생합성과 더불어 COX-2 mRNA의 수치가 상승작용을 일으키며 증가하였다. TGF-${\beta}$, 자하거와 이 둘의 조합인 자하거+TGF-${\beta}$은 COX-2 mRNA 발현, $PGE_2$ 생합성 및 골재흡수를 감소시켰다. 자하거(紫河車)는 IL-1${\beta}$, TNF-${\alpha}$와 IL-6 각각 또는 이들의 조합으로 인해 증가하는 COX-2 mRNA 발현과 $PGE_2$ 생성을 감소시키는 반면 COX-1 mRNA 발현에는 유의성 있는 영향을 미치지 않았다. 한편 자하거는 농도의존적으로 IL-1${\beta}$로 유발된 흰쥐의 과칼슘혈증을 감소시켰다. 이러한 결과는 흰쥐의 두개골 골아세포에서 $PGE_2$ 생산에 대한 IL-${\beta}$, TNF-${\alpha}$, IL-6의 상승작용이 COX-2의 유전자 발현 증가에 기인함을 보여주었다. Conclusions : 이러한 결과들로부터 자하거가 골대사과정중 골재흡수를 억제하는데 효과적임을 밝히게 되었으며, 자하거의 골다공증의 억제기전이 골재흡수관련 단백질들의 전사조절에 있음을 최초로 해명하게 되었다.

  • Objectives : To investigate the anti-inflammatory effects of Prunella vulgaris pharmacopuncture in lipopolysaccharide (LPS)-induced inflammatory rat model. Methods : Sprague-Dawley rats were divided into 5 groups; normal control (n=8), LPS control (n=8), LPS+Prunella vulgaris pharmacopuncture at CV4 (CV4, n=8), LPS+Prunella vulgaris pharmacopuncture at ST36 (ST36, n=8), and LPS+Prunella vulgaris pharmacopuncture at CV12 (CV12, n=8). Pharmacopuncture was given every two days for 4 weeks followed by inflammation induction by peritoneal LPS injection (5mg/kg). Proinflammatory cytokines including interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), tumor necrosis factor-$\alpha$ (TNF-$\alpha$), interleukin-10 (IL-10), thiobarbituric acid reactive substance (TBARS) from blood and liver tissue were compared before and 5 hrs after inflammation induction. Results : In CV4 and CV12 groups, plasma IL-$1{\beta}$, IL-6 and TNF-$\alpha$ levels increased by LPS injection, significantly decreased 5 hrs after injection (p<0.05). For CV12 group, plasma IL-10 concentration significantly increased (p<0.05). Liver IL-$1{\beta}$ and IL-6 levles significantly decreased in CV4 and CV12 groups (P<0.05), while normal and LPS control groups were not significantly different in TNF-$\alpha$ and IL-10 levels. Plasma TBARS concentration was significantly decreased in CV12 group, while there was no significant difference among LPS control and pharmacopuncture groups for liver TBARS concentration. Conclusions : Based on the present findings, Prunella vulgaris pharmacopuncture at CV12 may have a potentially preventive anti-inflammatory effect in an LPS-induced inflammatory rat model.

  • Adipose tissue-derived chronic inflammation contributes to development of insulin resistance in obesity, leading to type 2 diabetes and cardiovascular disease. Baicalin, a flavonoid, has antioxidant, anti-inflammatory, antihyperglycemic, anti-adipogenic, and antiobesity effects. However, whether baicalin attenuates adipose tissue-derived development of insulin resistance remains still unclear. This study was to investigate effect of baicalin on the inflammatory changes involved in the development of insulin resistance in adipose tissue. RAW 264.7 cells and differentiated 3T3-L1 adipocytes were pretreated with various concentrations of baicalin in complete media for 1 h and then cultured in the presence or absence of LPS or TNF-${\alpha}$. Our results demonstrated that baicalin remarkably inhibited LPS-induced production of TNF-${\alpha}$, IL-6, and NO by RAW 264.7 cells in a dose-dependent manner. Baicalin also inhibited TNF-${\alpha}$-induced production of IL-6 and $PGE_2$ in differentiated 3T3-L1 cells in a dose-dependent manner, while upregulated TNF-${\alpha}$-suppressed expression of adiponectin and PPAR-${\gamma}$ mRNA and IRS-1 protein. These findings suggest that baicalin may prevent the adipose tissue-derived development of insulin resistance in obesity.

  • The present study examined the ex vivo effect of Job's tear on immune function. Seven to eight week old mice(Balb/c) were fed a chow diet ad libitum two different concentrations (50 and 500 mg/kg BW) of water extract of Job's tear were orally administ every other day for two weeks. The results indicated that macrophage activation had occurred in the mice receiving 50 mg/kg B. W. of Job's tear water extract. Overall, using a mouse model, this study demonstrated that Job's tear extract may enhance immune function by regulating the $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ and IL-10 cytokine production capacity of activated macrophages in mice. This study may suggest that supplementation of Job's tear water extracts may enhance the immune function by regulating the enhancing the cytokine production by activated macrophage ex vivo.
