Purpose: This study was carried out to investigate the anti-tumor metastasis effect and activation of innate immunity by extracts of Mori radicis cortex. Methods: Anti-tumor metastatic experiment was conducted in vitro and in vivo by using colon 26-M3.1 carcinoma cell, L5178Y-R lymphoma cell and HeLa cell. To observe the activation of innate immunity by extracts of Mori radicis cortex, we estimated IL-6, IL-10, IL-12, TNF-${\alpha}$ from peritoneal macrophages. And we evaluated the activation of NK cell by using anti-asialo-GM1 serum. Results: We found that the administration of Mori radicis cortex extracts significantly inhibited tumor metastasis. In an in vitro cytotoxicity analysis, Mori radicis cortex affected tumor cell growth above specific concentration. Mori radicis cortex also stimulated peritoneal macrophage, which was followed by the production of various cytokines such as IL-6, IL-10, IL-12, TNF-${\alpha}$. The depletion of NK cells by anti-asialo GM1 serum partly abolished the inhibitory effect of Mori radicis cortex on tumor metastasis. Conclusion: Mori radicis cortex appears to have considerable activity on the anti-metastasis by activation of innate immunity.

Background : There are only a few studies regarding the causes of treatment failure for tuberculosis. Therefore, this study aimed to determine the causes of intractable tuberculosis. Methods : M. tuberculosis, differentiated MOTT (Mycobacterium Other Than Tuberculosis) were isolated, and the RFLP (Restriction fragments length polymorphisms) pattern was analyzed from 204 patients with pulmonary tuberculosis and 53 suffering from neck tuberculosis. The IL-$1{\beta}$, IL-12, $^*1\;IFN{\gamma}$ and $^*2\;TNF{\alpha}$ blood levels were measured. All patients were regularly followed for 18 months after treatment. Results : There was no correlation between the RFLP patterns of M. tuberculosis treatment failure. From the 204 cases, 31.9% were intractable. The characteristics of patients with intractable tuberculosis were old age, being male and recurrent cases. The causes of treatment failure were identified as follows ; a decrease in the IL-12(59.4%) concentration, drug resistant strain(54.7%), irregular medication(15.4%), MOTT(6.2%) and a heavy infection(4.6%). The causes of all cases of intractable tuberculosis could be investigated. The IL-12 concentration in the blood was significantly lower in the intractable cases, where it disclosed a maximum sensitivity(64.7%) and specificity(75.4%) at 165.0 pg/mL. Most of the 53 cases of neck node tuberculosis were treated successfully. Therefore, we were unable to analyze the cause of treatment failure. Conclusion : A decrease in the blood IL-12 concentration and drug resistant strains were identified as the most significant causes of treatment failure for tuberculosis. In Korea, infection by clusters were prevalent, but no difference in the clinical course between clusters and non-clusters could be found.

Background & Objective: The aim of this study was to investigate the effect of P. radix on the inflammatory related gene expression in IL-$1{\beta}$-stimulated primary human gingival fibroblast using Whole Transcript Sense Target (WT-ST). Method: Human gingival fibroblast was incubated with P. radix [100 or $200\;{\mu}g/ml$], and IL-$1{\beta}$ [$1ng/m{\ell}$] added an hour later. After 24h, total RNA was extracted using RNeasy Mini Kit and the whole gene expression patterns were performed using WT-ST Labeling $Assay^{(R)}$. Result: In the DEG results, 782 genes were up-regulated in the IL-$1{\beta}$-treated group as compared to control and among those, 43 genes were associated with inflammation. 981 genes were down-regulated after treatment with IL-$1{\beta}$ and of those 7 genes were associated with inflammation. 1439 genes were up-regulated after treatment with P. radix plus IL-$1{\beta}$-treated when compared to IL-$1{\beta}$-treated alone group and 1225 genes were down-regulated in the same condition. Among the down-regulated genes, 5 were associated with inflammation- and inhibitor genes such as GDF15 and LIF. In the analysis of the P. radix plus IL-$1{\beta}$-treated group, the most significant pathways were the cytokine-cytokine receptor interaction, toll-like receptor signaling, JAK-STAT signaling and tyrosine metabolism. The gene expression patterns in the P. radix $200{\mu}g/m{\ell}$ plus IL-$1{\beta}$-treated group appear to be more involved in the metabolism-related pathways than in the $100{\mu}g/m{\ell}$ plus IL-$1{\beta}$-treated group. Conclusion & Discussion: By microarray analysis of gene expression data, we are able to identify gene expression patterns associated with not only anti-inflammation effect but also transcription function of P. radix.

The purpose of this study is that evaluate the distribution and biological roles of TNF-a, interleukin-1${\beta}$(IL-1${\beta}$), interleukin-6(IL-6) and tissue inhibitors of metalloproteinase-1(TIMP-1) in the synovial fliud of patients with non-inflammatory chronic temporomandibular joint(TMJ) disorders in relation to pain during joint movements and magnetic resonance imaging(MRI) findings. TMJ synovial fluids aspirates were obtained from 36 patients (36 joints) with chronic TMJ disorders and from 8 controls(8 joints). Patients were divided to four groups. The control group was from healthy volunteers(8 joints), group I(18 joints) was patients with anterior disc displacement with reduction, group II(5 joints) was patients with disc displacement without reduction and group III (5 joints) was osteoarthritis. The TNF-${\alpha}$, IL-1${\beta}$ and IL-6 levels in the aspirates were determined by using an enzyme-linked immunosorbent assay and the TIMP-1 level was measured by an enzyme immunoassay. Following examinations for pain during joint movements and MRI observations, these cytokines' level and frequencies of detection were compared. The level of IL-1${\beta}$was not significant different in all groups. but the level of TNF-${\alpha}$, IL-6 and TIMP-1 were significant different among groups. The level of IL-6 and TIMP-1 were correlated to pain during movement(p<0.01) and the level of TNF-a(p<0.05). Also, the level of IL-6 was correlated to the level of TIMP-1(p<0.01). Especially, The level of the TIMP-1 level was significantly correlated to the pain during movement and showed very high levle of Pearson's correlation coefficient (r=0.833)(p<0.001). The results indicated that the TNF-${\alpha}$, IL-6 and TIMP-1 levels in the TMJ aspirates of patients with chronic TMJ disorders have been raised. Especially, IL-6 and TIMP-1 were very high levels in the patients who were degraded in the TMJ. Also, TNF-${\alpha}$, IL-6 and TIMP-1 showed the significant correlation in the chronic temporomandibular joint disorders. Therefore I suggest that these cytokines were also correlated to the pain during movement in the chronic temporomandibular joint disorders.

Purpose: Smokeless tobacco-based oral-use products like gutka are popular in India. Gutka usage leads to increased periodontal destruction and inflammation; however, the relevant mechanism remains unknown. This study aimed to elucidate the role of gutka in periodontitis by examining its effect on the levels of interleukin (IL) $1{\beta}$ and IL-8 from the gingival crevicular fluid (GCF). Methods: A total of 45 patients were enrolled in this study. Thirty patients with periodontitis (15 gutka chewers [GCP] and 15 nongutka chewers [NGC]) and 15 periodontally healthy controls (HC) were selected. The full-mouth plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and recession (RC) were recorded. The IL-$1{\beta}$ and IL-8 levels in the GCF of all subjects were assessed through an enzyme-linked immunosorbent assay (Quantikine). Results: The IL-$1{\beta}$ and IL-8 levels were not significantly higher in the GCP group (IL-$1{\beta}$, $369.01{\pm}273.44{\mu}L$; IL-8, $205.97{\pm}196.78{\mu}L$) as compared to those in the NGC group (IL-$1{\beta}$, $195.57{\pm}96.85{\mu}L$; IL-8, $178.61{\pm}149.35{\mu}L$). More gingival RC and loss of attachment was seen among the GCP group (RC: $2.02{\pm}0.31$, P=0.013; CAL: $4.60{\pm}0.56$, P<0.001) than among the NGC group (RC, $1.21{\pm}1.15$; CAL, $3.70{\pm}0.32$); however, PD was deeper among the NGC subjects (P=0.002). PI and GI were significantly higher for the periodontitis group (P<0.001) when compared to the HC, but there was no difference among gutka chewers and non-chewers (P=0.22 and P=0.89). A positive correlation was found between the IL-8 levels and the duration of gutka chewing (r=-0.64, P<0.01). Conclusions: Gutka chewing leads to increased gingival RC and clinical loss of attachment. There was no effect seen in the proinflammatory cytokine levels in the GCF of gutka users.

Treponema maltophilum, a Group IV oral spirochete, is associated with periodontitis and endodontic infections. In this study we analyzed the functional role of the major surface protein of this organism (MspA) in human gingival fibroblasts (HGFs). The full-length gene encoding MspA was cloned and expressed in Escherichia coli by using the expression vector pQE-30. The recombinant protein (rMspA) was purified by affinity chromatography with nickel-nitrilotriacetic acid agarose and possible contamination of E. coli endotoxin in rMspA was removed by using polymyxin B-agarose. rMspA significantly induced the expression of pro inflammatory cytokines like IL-6 and IL-8 and intercellular adhesion molecule (ICAM)-1 in HGFs, when analyzed by reverse transcription-PCR, flow cytometry, and enzyme-linked immunosorbent assay. Our results indicate that MspA of T. maltophilum may play an important role in amplifying the local immune response by upregulating the expression of proinflammatory cytokines and ICAM-1.

In 1998, Osada and co-workers isolated 140 mg of a novel cytokine modulator from 18 L of the culture broth of Streptomyces RK95- 31 isolated from a soil sample in Hiroshima Prefecture. This new immunosuppressant was named (-)-cytoxazone and its absolute configuration was determined on the basis of its NMR, CD and X -ray analysis. It interferes with cytokine IL4, IL10 and IgG production by selective inhibition of the signaling pathway of Th2 cells, but not Thl cells. Inhibitors of Th2-dependent cytokine production have potential as potent chemotherapeutic agents in the field of immunotherapy. The (-)-cytoxazone is different from known immunomodulators such as FK 506 and rapamycin in respect of structure and biological activity. As such cytoxazone should be a useful tool for understanding signaling pathways in Th2 cells, the synthesis of (-)-cytoxazone is of interest for the development of new cytokine modulators.
