PURPOSE: Low grade inflammation is a well-known characteristic in obese subjects. We investigated body weight changes and inflammatory markers after 12-week intervention trial. MATERIALS AND METHODS: Twenty-six obese subjects were enrolled and 19 (13 men and 6 women) completed the study. Sibutramine is an FDA-approved drug for body weight control; therefore, we chose this drug as the standard treatment medication in this study. Patients were randomly allocated to receive an anti-inflammatory agent (Diacerein treatment group; n = 12) or placebo (n = 7) for 12 weeks. Anthropometry, body proportion by dual-energy X-ray absorptiometry, and metabolic parameters at the beginning and end of study were measured and compared. RESULTS: The treatment group had a tendency towards more reduction in anthropometry as compared to the placebo group, in body weight reduction (- 7.0 kg vs. - 4.6 kg), body mass index (- 2.51 kg/m2 vs. - 1.59 kg/m2), and waist circumference (- 7.3 cm vs. - 4.4 cm). These reductions were not statistically significant. Changes in levels of high-sensitivity C-reactive protein and adiponectin in the treatment group were more favorable than in the placebo group. CONCLUSION: This small pilot study showed no statistical difference for changes in anthropometry, and inflammatory markers between the two groups. Therefore, we could not find any additional effects of Diacerein on weight loss and inflammatory variables in this study.

Matteuccia struthiopteris is a nature plant, which contains a lot of potential active components. In the present study, we investigated the effect of polysaccharides extracted from Matteuccia struthiopteris on lupus-like syndrome induced by Campylobacter jejuni CJ-S131 in BALB/c mice. Mice were randomly divided into normal, model control, SLE model (vehicle treated), Matteuccia struthiopteris polysaccharides treated (30 and 15 mg x kg(-1)) groups and prednisone 5 mg x kg(-1) treated groups. The effect of Matteuccia struthiopteris polysaccharides (Ms) on weight and organ index of BALB/c mice was detected. Autoantibodies and total IgG production were measured by enzyme linked immunosorbent assay. Proteinuria was measured and kidneys were examined by light microscopy. Compared with SLE model group, treatment with Matteuccia struthiopteris polysaccharides 30 and 15 mg x kg(-1) reduced weight loss and Matteuccia struthiopteris polysaccharides 15 mg x kg(-1) reduced spleen swelling (P < 0.05). The increased production of autoantibodies and total immunoglobulin G (IgG) were also significantly inhibited. Matteuccia struthiopteris polysaccharides protected kidney against glomerular injury in BALB/c mice with reduced immunoglobulin deposition and lowered proteinuria (P < 0.01). Matteuccia struthiopteris polysaccharides had a protective effect on lupus-like syndrome induced by CJ-S131 in BALB/c mice.

TNF-alpha is a major cytokine involved in inflammatory bowel disease (IBD). In this study, water extract of Grifola frondosa (GFW) was evaluated for its protective effects against colon inflammation through the modulation of TNF-alpha action. In coculture of HT-29 human colon cancer cells with U937 human monocytic cells, TNF-alpha-induced monocyte adhesion to HT-29 cells was significantly suppressed by GFW (10, 50, 100 microg/ml). The reduced adhesion by GFW correlated with the suppressed expression of MCP-1 and IL-8, the major IBD-associated chemokines. In addition, treatment with GFW significantly suppressed TNF-alpha-induced reactive oxygen species production and NF-kappaB transcriptional activity in HT-29 cells. In differentiated U937 monocytic cells, LPS-induced TNF-alpha production, which is known to be mediated through NF-kappaB activation, was significantly suppressed by GFW. In an in vivo rat model of IBD, oral administration of GFW for 5 days (1 g/kg per day) significantly inhibited the trinitrobenzene sulfonic acid (TNBS)-induced weight loss, colon ulceration, myeloperoxidase activity, and TNF-alpha expression in the colon tissue. Moreover, the effect of GFW was similar to that of intra-peritoneal injection of 5-aminosalicylic acid (5-ASA), an active metabolite of sulfasalazine, commonly used drug for the treatment of IBD. The results suggest that GFW ameliorates colon inflammation by suppressing production of TNF-alpha as well as its signaling through NF-kappaB leading to the expression of inflammatory chemokines, MCP-1 and IL-8. Taken together, the results strongly suggest GFW is a valuable medicinal food for IBD treatment, and thus may be used as an alternative medicine for IBD.
