Background: This research was performed to investigate the effects of Pulsatilla Koreana NAKAI pharmacopuncture (PPA) therapy on intestinal disease in rats with dextran sulfate sodium (DSS)-induced colitis. Methods: The subjects were divided into five groups : A control group, saline group, pharmacopuncture group PPA1 ($0.2mg/1kg/40{\mu}{\ell}$), pharmacopuncture group PPA2 ($0.5mg/1kg/40{\mu}{\ell}$), and pharmacopuncture group PPA 3($1mg/1kg/40{\mu}{\ell}$). The experimental model of colitis was induced by infection of dextran sulfate sodium (DSS) for eighteen days. After colitis was induced, PPA therapy was practiced on the Chunchu (ST25) once every two days for a total six times. Thereafter Disease Activity Index (DAI), colon length, damage to the colonic mucosa, body weight, IL-6, IL-10, $IL-1{\beta}$, $IFN-{\gamma}$, $TNF-{\alpha}$, $TGF-{\beta}1$, IL-23 and IL-17 were measured. Results: The results were as follows. 1. DAI was significantly decreased in the PPA groups. 2. Colon length was significantly increased in the PPA groups. 3. Damage of colonic mucosa was observed less in the PPA groups. 4. Body weight was significantly increased in the saline group and the PPA groups. 5. The PPA2 group showed a significant decrease in the intensity of IL-6, $IL-1{\beta}$, $IFN-{\gamma}$ and $TNF-{\alpha}$ levels and the mean of IL-23. 6. The PPA3 group showed a significant increase in the intensity of IL-10 and $TGF-{\beta}1$ levels. 7. No significant differences were shown in the mean of IL-17. Conclusion: These results suggest that PPA therapy on Chunchu (ST25) can be used as an effective treatment for inflammatory bowel disease.

In this study, four compounds isolated from the red alga Laurencia snackeyi were evaluated for their potential anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. These compounds were tested for their inhibitory effects on nitric oxide (NO) production in LPS-stimulated RAW 264.7 cells. Since $5{\beta}$-hydroxypalisadin B showed the best activity it was further tested for the production of prostaglandin-$E_2$ ($PGE_2$), expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), the release of pro-inflammatory cytokines tumor necrotic factor-alpha (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6). $5{\beta}$-Hydroxypalisadin B significantly reduced the $PGE_2$ release and suppressed the iNOS and COX-2 expression in LPS-stimulated RAW 264.7 cells. It also significantly reduced the release of pro-inflammatory cytokines TNF-${\alpha}$, IL-$1{\beta}$, and IL-6. These findings provide the first evidence of anti-inflammatory potential of $5{\beta}$-hydroxypalisadin B isolated from the red alga L. snackeyi and hence, it could be exploited as an active ingredient in pharmaceutical, nutraceutical and functional food applications.

Objective : The purpose of this study was to investigate the effects of Aurothiomalate acupuncture containing Sodium Aurothiomalate on Type II collagen-induced arthritic DBA/1 mice. Methods : The mice were divided into three groups, one control group and two test groups. The control group was injected with saline on Choksamni(ST36) and the two test groups were injected either with Aurothiomalate acupuncture into Choksamni(AT1 group), or with Aurothiomalate acupuncture into Hwando(G30, AT2 group). We measured the incidence of arthritis, the mean index of arthritis, the number of arthritic limbs for the clinical examination and evaluation. We also examined the changes in the level of TNF-$\alpha$ and IL-$1{\beta}$. Results : 1. The incidence of arthritis in mice of the AT1 and AT2 groups were significantly lower than that of the control group. 2. The mean indices of arthritis in mice of the AT1 and AT2 groups were significantly lower than that of the control group. 3. The mean number of arthritic limbs in mice of the AT1 and AT2 groups were significantly lower than that of the control group. 4. The levels of TNF-$\alpha$ of the mice in the AT1 and AT2 groups were significantly different from that of the control group. 5. The levels of IL-$1{\beta}$ of the mice in the AT1 and AT2 groups were not significantly different from that of the control group. Conclusion : These results indicate that the treatment with Aurothiomalate acupuncture could improve the clinical status of Arthritis by suppressing immune responses in the mice of Type II collagen-induced arthritic.

Purpose: This study was performed to investigate the effects of Dangguijakyaksan on the development of experimentally-induced endometriosis in rats. Methods: Endometriosis was induced in rats by autotransplanting uterine tissue to the peritoneum and divided them into three groups: (1) sham-operated group(n=8). (2) surgically induced endometriosis and untreated control group(n=8). (3) surgically induced endometriosis and Dangguijakyaksan treated group. Dangguijakyaksan was orally administrated for 15 days after operation. Then we measured the body weight. the volume of endometriotic implants. the weight of uterus and ovary. and analysed the concentration of cytokines (MCP-1, TNF-$\alpha$, IL-1$\beta$, IL-6) in peritoneal fluids. Histopathology, immunohistochemistry for COX-2 and VEGF. and histochemistry for mast cell in transplanted uterine tissue were also performed. Results: - The volume($mm^3$) of endometriotic implants in Dangguijakyaksan treated group was significantly decreased compared with control group. - The concentration(pg/ml) of MCP-1, TNF-$\alpha$ and IL-l$\alpha$ in peritoneal fluids in Dangguijakyaksan treated group was significantly decreased compared with control group. - Histopathologically, proliferation of endometriotic epithelia. infiltration of inflammatory cells and angiogenesis in transplanted uterine tissue of Dangguijakyaksan treated group were weakly observed than those of control group. - The percentage of positive epithelial layers for COX-2 in Dangguijakyaksan treated group was significantly decreased compared with control group. - The VEGF expression of endometriotic epithelia, neovascular endothelia and stromal cells in transplanted uterine tissue of Dangguijakyaksan treated group were weakly observed than those of control group. - The number of mast cells in transplanted uterine tissue in Dangguijakyaksan treated group was significantly decreased compared with control group. Conclusion: On the basis of these results. we concluded that Dangguijakyaksan has inhibiting effects on the development of transplanted uterine tissue. And these effects may be related with decreased production of MCP-1, TNF-$\alpha$ and IL-1$\beta$, and decreased expression of COX-2 and VEGF, and inhibition of mast cell infiltration by administration of Dangguijakyaksan.

Human polymorphonuclear leukocytes(PMN) are the most numerous host cell in periodontal pockets and their presumed role is to form a protective barrier between the bacteria and periodontal tissues. Microbial component LPS activates macrophages to produce $IL-1{\beta}$, $MIP-1{\alpha}$, $-1{\beta}$, $TNF-{\alpha}$ and IL-6, etc. These cytokines have autocrine function to the macrophages, and paracrine function to other cell such as PMN and affect them to produce some biological functions. In the present study, human PMN were tested for the expression of $IL-1{\beta}$ and $MIP-1{\alpha}$ mRNA. Also we performed the receptor binding assay and in vitro assay for the antimicrobial action of HL-60 cell to determine whether HL-60 can replace the peripheral PMN in analyzing the biological functions. PMN were stimulated with $IL-1{\beta}$, TPA, $MIP-1{\alpha}$, LPS, IL-2 and total cytoplasmic RNA were extracted for the northern blot analysis. In order to determine the induction kinetics of $IL-1{\beta}$ or $MIP-1{\alpha}$ mRNA expression, cells were stimulated for 0,1,2,3 hours. We found peak expression of $IL-1{\beta}$ mRNA after 1hr of induction with $IL-1{\beta}$, LPS and after 2hr of induction with TPA. $MIP-l{\alpha}$ also induced but a scarce $IL-l{\beta}$ message from PMN. In contrast to the $IL-l{\beta}$ mRNA expression, $MIP-1{\alpha}$ were not induced from PMN in any culture conditions. Receptors for $MIP-1{\alpha}$ were identified on dibutyryl cyclic AMP(dbcAMP)-treated HL-60 as well as peripheral PMN. dbcAMP treatment significantly enhanced antimicrobial action of undifferentiated HL-60 cell. MIP-1 further increased enhancing effect of dbcAMP. $IL-1{\beta}$, to a lesser extent, also increased dbcAMP-induced enhancing effect of antimicrobial action of HL-60 cell.

Obesity is consistently increasing in prevalence and can trigger insulin resistance and type 2 diabetes. Many lines of evidence have shown that macrophages play a major role in inflammation associated with obesity. This study was conducted to determine metformin, a widely prescribed drug for type 2 diabetes, would regulate inflammation through down-regulation of scavenger receptors in macrophages from obesity-induced type 2 diabetes. RAW 264.7 cells and peritoneal macrophages were stimulated with LPS to induce inflammation, and C57BL/6N mice were fed a high-fat diet to generate obesity-induced type 2 diabetes mice. Metformin reduced the production of NO, $PGE_2$ and pro-inflammatory cytokines ($IL-1{\beta}$, IL-6 and $TNF-{\alpha}$) through down-regulation of $NF-{\kappa}B$ translocation in macrophages in a dose-dependent manner. On the other hand, the protein expressions of anti-inflammatory cytokines, IL-4 and IL-10, were enhanced or maintained by metformin. Also, metformin suppressed secretion of $TNF-{\alpha}$ and reduced the protein and mRNA expression of $TNF-{\alpha}$ in obese mice as well as in macrophages. The expression of scavenger receptors, CD36 and SR-A, were attenuated by metformin in macrophages and obese mice. These results suggest that metformin may attenuate inflammatory responses by suppressing the production of $TNF-{\alpha}$ and the expressions of scavenger receptors.

Immunoregulative action of 70% ethyl alcohol fraction of Cervus nippon was investigated in vitro. The fraction enhanced the proliferation of thymocytes and the population of CD4$\^$+/CD8$\^$-/ single-positive cells in thymocytes. CN-E enhanced [Ca$\^$2+]$\sub$i/, the production of TNF-${\alpha}$ and IL-1 ${\beta}$, and phagocytosis in peritoneal macrophages. The fraction did not induce the proliferation of splenocytes and DNA fragmentation in thymocytes. These results indicate that 70% ethyl alcohol fraction of Cervus nippon regulates immunological action by stimulating murine thymocytes and macrophages.
