This study was carried out to investigate the effects of SMG on the in vitro and in vivo inflammatory reactions. In experiment I, in vitro tests, ethanol extract of SMG showed potent radical scavenging activity tested by DPPH(I,1-diphenyl-2-picryl-hyrazyl) method and inhibited the lipopolysaccharide-induced gene expressions of interleukin-1${\beta}$, interleukin-6 and tumor necrosis factor-${\alpha}$ (above 50$\%$ at a concentration of 50㎍／㎖) by the macrophage RAW 246.7 cells. Among the herbal ingredients of SMG, ethanol extracts of Scutellaria baicalensis, Paeonia lactiflora, Glycyrrhiza glabra showed potent radical scavenging activity. And Glycyrrhiza glabra and Scutellaria baicalensis showed potent inhibitory activity of nitric oxide production. Especially, ethanol extract of Scutellaria baicalensis inhibited the gene expression of IL-1${\beta}$, IL-6 and TNF-${\alpha}$. In cyclooxygenase-2 assay, Scutellaria baicalensis and Glycyrrhiza glabra showed the potent inhibition of prostaglandin E2 generation. In experiment 2, in vivo tests, SMG showed inhibitory effects on vascular permeability (28.7$\%$) and leukocyte migration (11.5$\%$). These results mean that SMG has a anti-inflammatory effects by it's inhibitory effects of leukocyte migration and vascular permeability as well as it's inhibitory effects of lipopolysaccharide-induced gene expression of IL-1${\beta}$, IL-6 and TNF-${\alpha}$, and radical scavenging activity. Therefore, I expect that SMG may be used as a effective drug for treatment on inflammation.

Final goal of periodontal treatment is to reconstruct the destructed periodontal tissue as well as to remove the necrotic pathologic elements. The purpose of this study is to investigate on the effect of Zizyphi extract to the inhibitory ability on collagenolytic activity of P gingivalis, biologic activity of gingival fibroblasts, and on the collagen and protein synthesis of gingival fibroblasts. Gingival fibroblast from giniva of first bicuspids from patient for orthodontic treatment were used and cultured. For the measurement of inhibitory ability of collagenolytic activity, crude enzyme was extracted and used on the basis of modified Ono's method. On the inhibition of collagenolytic enzyme from herbal extracts, collagenokit CLN-100 were used. The cellular activity of gingival fibroblast, were studied using MTT solution and measured optical density on 570mm by ELISA reader. To measure the effects on the ability of whole protein and collagen synthesis, cell membrane was destructed with ultrasonic grinder after culturing, centrifuged and counted by liquid scintilation counter. The inhibitory effects on producing of $IL-l{\beta}$ by monocyte, after promotion of producing $IL-l{\beta}$ by LPS, were compared with the mixture of herbal extracts and other drugs using thymocyte stimulation assay. About inhibitory effects of $PGF_2$. by gingival fibroblasts, herbal extract was compared with the addition of the other control groups using enzyme imunoassay. On the inhibition of collagenolytic activity by P. gingivalis, benzene extracts showed the most efficient inhibitory effects among the $19{\mu}g/ml$ of the compared extracts and 40.5% by Tetracycline. On the cellular activity promoting effects, compared extracts showed a bit of more effects than PDGF of $100{\mu}g/ml$ concentration and IGF of $20{\mu}g/ml$ concentration. All of the PDGF, IGF, Zizyphi Fructus extract should increase in collagen synthesis, but especially 70% ethylalcohol extracts of Zizyphi Fructus showed comparably high effects among the compared extracts. Effects on whole protein synthesis were slightly increased on every extract but especially 70% ethylalcohol extract showed significantly effective than any other estract. On the inhibitory effects of Zizyphi Fructus $IL-l{\beta}$ production by monocyte, compared extracts showed 70% of highly inhibitory effect than that of 60% inhibition effects on controlled group and each extracts showed no significant difference. In $PGF_2$ production inhibitroy effect of Zizyphi Fructus gingival fibroblasts, Herbal extracts showed 70% of inhibition comparing with tat of 90.2% of controlled group, but each extracts showed similar effects excluding the $H_2O$ extracts. These results suggested that Zizyphi Fructus might be useful medicine for inhibition of inflammatory mediator including $IL-l{\beta}$ and $PGF_2$.

In this study, we examined the inhibitory effects of propenone derivatives, 1,3-diphenyl-propenone (DPhP), 3-phenyl-1-thiophen-2-yl-propenone (PhT2P), 3-phenyl-1-thiophen-3-yl-propenone (PhT3P) and 1-furan-2-yl-3-phenyl-propenone (FPhP), on $TNF-{\alpha}$-induced nuclear factor (NF)-${\kappa}B$ activity and interleukin (IL)-8-induced monocyte adhesion to colon epithelial cells. 1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) that is previously reported as a $NF-{\kappa}B$ inhibitor suppressed $TNF-{\alpha}$-induced monocyte-epithelial cell adhesion in a concentration-dependent manner. The propenone derivatives, DPhP, PhT2P, PhT3P, FPhP, also inhibited $TNF-{\alpha}$-induced $NF-{\kappa}B$ activation in a similar degree to FPP-3. In a DPPH radical scavenging assay, none of the compounds showed DPPH radical scavenging activity, indicating that the inhibitory actions of the propenone derivatives on redox-sensitive $NF-{\kappa}B$ activity is not due to a simple free radical scavenging activity. In addition, the propenone derivatives also suppressed the IL-8-induced monocyte adhesion to colon epithelial cells. Furthermore, the effective concentrations of the propenone derivatives on both $NF-{\kappa}B$ activation as well as IL-8 induced monocyte-epithelial cell adhesion were 1000 times lower than 5-aminosalicylic acid (5-ASA), a clinically used drug for inflammatory bowel disease. These results suggest that the propenone derivatives may be a potential lead having a strong inhibitory activity against inflammatory cytokine-induced epithelial inflammation.

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.

Objectives : We investigated the synergistic effects of bee venom (BV) and natural killer (NK) cells on B16F10 melanoma cell apoptosis mediated by IL-4. Methods : We performed a cell viability assay to determine whether BV can enhance the inhibitory effect of NK-92MI cells on the growth of B16F10 melanoma cells, and western blot analysis to detect changes in the expression of IL-4, $IL-4R{\alpha}$, and other apoptosis-related proteins. EMSA was performed to observe the activity of STAT6. To confirm that the inhibitory effect of BV and NK cells was mediated by IL-4, the above tests were repeated after IL-4 silencing by siRNA (50 nM). Results : B16F10 melanoma cells co-cultured with NK-92MI cells and simultaneously treated by BV ($5{\mu}g/ml$) showed a higher degree of proliferation inhibition than when treated by BV ($5{\mu}g/ml$) alone or co-cultured with NK-92MI cells alone. Expression of IL-4, $IL-4R{\alpha}$, and that of other pro-apoptotic proteins was also enhanced after co-culture with NK-92MI cells and simultaneous treatment with BV ($5{\mu}g/ml$). Furthermore, the expression of anti-apoptotic bcl-2 decreased, and the activity of STAT6, as well as the expression of STAT6 and p-STAT6 were enhanced. IL-4 silencing siRNA (50 nM) in B16F10 cells, the effects of BV treatment and NK-92MI co-culture were reversed. Conclusion : These results suggest that BV could be an effective alternative therapy for malignant melanoma by enhancing the cytotoxic and apoptotic effect of NK cells through an IL-4-mediated pathway.

The inhibitory effects of the Juglans sinensis walnut ethanol extract (JSWE) on carbon tetrachloide (CCl₄)-induced fibrosis, serum transaminases (GOT and GTP), hepatic glutathione (GSH), serum pro-inflammatory cytokines (IL-1β and IL-6) were investigated in rats. JSWE significantly inhibited on CCl₄-induced fibrosis in dose-dependent manner. Moreover, JSWE significantly inhibited on the serum levels of GOT, GTP, IL-1β, and IL-6 in dose-dependent manner in CCl₄-induced fibrosis rat. However, JSWE markedly increased the production of hepatic GSH in a dose-dependent manner. These results show that JSWE may explain some known biological activities of Juglans sinensis walnut including their anti-fibrotic and anti-inflammatory effects, and is of considerable benefit in the treatment for live diseases.

The inhibitory effects of tetrahydropapaverine on serotonin biosynthesis in serotonin-producing murine mastocytoma P815 cells were investigated. Tetrahydropapaverine at concentration ranges of 5-20 M decreased serotonin content in a concentration-dependent manner in P815 cells and showed 42.1 % inhibition of serotonin content at 5.0 M for 24 hr. The value of 50 % inhibitory concentration, IC$\sub$50/, of tetrahydropapaverine was 6.2 M. Under these conditions, tryptophan hydroxylase (EC 1.14.16.4, TPH), was inhibited for 24-36 hr after treatment with tetrahydropapaverine in P815 cells(49.1 % inhibition at 7.5 M). (omitted)

In order to evaluate the antitumor activity and immunomodulatory effects of Seoleosojong-tang(SST), studies were done. We measured the cytotoxic activity for various kinds of cancer cells, inhibitory effect on activity of DNA topoisomerase I, cell adhesion to complex extracellular matrix, survival time in ICR bearing S-180, pulmonary colonization and histological changes of lung in C57BL/6 injected i.v. with B16-F10, CAM assay, expression of CD4/sup +/, CD8/sup +/, B220/sup +/, cytokine gene in spleen cell. The results were obtained as follows: 1. In cytotoxicity against A549, HT1080, 816-F10, NCL-H661 was showed cytotoxicity as compared with control. 2. The inhibitory effect on adhesion of A549, 816-F10 to complex extracellular matrix was over 40% at 100 ㎍/㎖ of SST. 3. In DNA topoisomerase I assay, SST has inhibitory effect. 4. The T/C% was 120.8 in SST treated group in S-180 bearing ICR mice. 5. In pulmonary colonization assay, a number of colonies were decreased significantly and histological changes were showed that infiltration area of cancer cells were inhibited effectively in SST treated group. 6. In CAM Assay, SST has antiangiogenic effect. 7. On the expression of positive cell to CD4/sup +/, CD8/sup +/ and 8220/sup +/ in spleen cells, CD4/sup +/ cells were increased significantly in SST treated group. 8. Effect of SST on IL-1β gene expression in splenic cell was significantly increased as function of whole concentration. 9. The gene expression of IL-4, IL-6, IL-10, IL-12, IFN-γ, TNF-α were increased in SST treated group. From above results SST could be usefully applied for antitumor activity and immunomodulatory effects, but further research of SST should be required.
