In this study we manufactured mulberry fruit tea(MFT) to be used as an anti-inflammatory agent. Here, MFT was consumed by thirty middle-aged women with symptoms of rheumatoid arthritis for 4 weeks. The anthropometric measurements and serum inflammatory factors were measured before and after consumption of the MFT. For the anthropometric measurements, BMI and body fat decreased after 4 weeks of tea consumption although there were no significant differences. The serum inflammatory factors(uric acid and homocysteine) as well as serum amino transferase activity(aspartate trans-aminase and alanine transaminase) showed a decreasing trend. In addition, serum carbon reactive protein(CRP) decreased significantly decreased after MFT consumption 4 weeks. It's concluded that this MFT is helpful to for rheumatyroid arthritis patients in order to decrease serum inflammatory factors such as CRP.

Background: Although ginsenosides and saponins in Korea red ginseng (KRG) shows various pharmacological roles, their roles in the inflammatory response are little known. This study investigated the anti-inflammatory role of ginsenosides identified from KRG saponin fraction (RGSF) and the potential mechanism in macrophages. Methods: The ginsenoside composition of RGSF was identified by high-performance liquid chromatography (HPLC) analysis. An anti-inflammatory effect of RGSF and its mechanisms were studied using nitric oxide (NO) and prostaglandin E₂ (PGE₂) production assays, mRNA expression analyses of inflammatory genes and cytokines, luciferase reporter gene assays of transcription factors, and Western blot analyses of inflammatory signaling pathways using the lipopolysaccharide (LPS)-treated RAW264.7 cells. Results: HPLC analysis identified the types and amounts of various panaxadiol ginsenosides in RGSF. RGSF reduced the generation of inflammatory molecules and mRNA levels of inflammatory enzymes and cytokines in LPS-treated RAW264.7 cells. Additionally, RGSF inhibited the signaling pathways of NF-κB and AP-1 by suppressing both transcriptional factors and signaling molecules in LPS-treated RAW264.7 cells. Conclusion: RGSF contains ginsenosides that have anti-inflammatory action via restraining the NF-κB and AP-1 signaling pathways in macrophages during inflammatory responses.

The pathogenesis of inflammatory bowel diseases is not very well understood; it is currently thought to be caused by the interaction between genetic factors, environmental factors, intestinal microbes, and immune factors. Biological agents such as anti-tumor necrosis factor (anti-TNF) are widely being used as therapeutic agents. Infliximab, a chimeric monoclonal IgG1 antibody against tumor necrosis factor, has been demonstrated to have an effect in the induction and maintenance of remission in Crohn's disease in children. The effects of biological agents, typified by anti-TNFs, in inflammatory bowel disease in children; the recent concern on the administration of biological agents in combination with immunomodulators; and 'Top-down' therapy are some of the topics covered in this review.

Chronic inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated neuropathy with heterogeneous features. Appropriate treatment will produce a favorable outcome, but a poor treatment response and severe disability have also been reported. The roles of the clinical phenotypes and electrophysiological features of CIDP as well as of autoantibodies against nodal and paranodal proteins have been highlighted previously due to their association with the treatment response and long-term prognosis. This review addresses the diverse factors associated with the prognosis of CIDP.

Inflammation is an immune response of the human body but excessive inflammation is taken as a major factor in the development of many diseases including autoimmune disorders, cancer and nerve disorders etc. In this regards the need is to suppress the inflammatory response. Suppression of extra or imperfect inflammatory response is not a big deal provided there is an exact knowledge of particular target in the body. Recent advancements in Pharmacological aspect made the therapy with improved outcomes in number of patients. Anticytokine therapy might be one of the important and novel approaches for inflammation and Arthritis. This can be achieved only when we go through the pathophysiology of expression and identification of mediators. Let's take an example of cytokine like interleukins (IL), chemokines, interferons (INF), tumor necrosis factors (TNF-α), growth factors, and colony stimulating factors) release pathway which is a major signalling protein in inflammatory response. In the present study we have reviewed the recent pharmacological therapeutic advancement, inflammatory mediators, receptors, and major signalling pathways. Such information will not only provide the idea about the mechanism of action of Pharmaceuticals and molecular targets but also it provides a new aspect for drug designing and new corrective approaches in existing clinical medicines. This study will be a source of good information for the researchers working in the area of drug designing and molecular Pharmacology especially in anti-inflammatory and anti arthritic medicines for target based therapy.

Inflammation is the immune system's response to infection and injury-related disorders, and is related to pro-inflammatory factors (NO, $PGE_2$, cytokines, etc.) produced by inflammatory cells. Atopic dermatitis (AD) is a representative inflammatory skin disease that is characterized by increasing serum levels of inflammatory chemokines, including macrophage-derived chemokine (MDC). Carpinus tschonoskii is a member of the genus Carpinus. We investigated the anti-inflammatory activity of C. tschonoskii by studying the effects of various solvent fractions prepared from its leaves on inflammatory mediators in HaCaT and RAW264.7 cells. We found that the chloroform fraction of C. tschonoskii inhibited MDC at both the protein and mRNA levels in HaCaT cells, acting via the inhibition of STAT1 in the IFN-${\gamma}$ signaling pathway. In addition, the chloroform fraction significantly suppressed the expression of inflammatory factors induced by lipopolysaccharide stimulation, except COX-2 and TNF-${\alpha}$. These results suggest that the chloroform fraction of C. tschonoskii leaves may include a component with potential anti-inflammatory activity.
