The present study suggests that EM 1201 has protective activity against arthritis and demonstrated its potential beneficiary effect analogical to diclofenac. Anti-inflammatory and anti-oxidative effect of EM 1201 in rats with AA support the need of further investigations by using it as supplementary agent alone or together with other anti-arthritic drugs in the treatment of rheumatoid arthritis.
The present study aimed to investigate the antiinflammatory effects of 2 herbal extracts (CDS and CDSM) in rats with experimental adjuvant arthritis (AA). Joint swelling, development of polyarthritis, blood indices, pro/antioxidant activity, and proinflammatory cytokine IL-17 in blood serum, as well as the liver and paw histopathology and histochemistry, were assessed. Oral injections of extracts showed an antiinflammatory effect analogous to that of diclofenac (DF), improved blood indices and suppressed level of IL-17, significantly diminished joint swelling, and histological changes in the joints. Increase in CAT activity and AOA and reduction in lipid peroxidation was noted. The preparations did not show toxic effects on the liver. The obtained results suggest that the prophylactic use of CDS and CDSM have a significant effect on slowing AA progression, similar to the effect of DF. Both preparations could be potential preventive or therapeutic candidates for the treatment of autoimmune processes in combination with other drugs.
Background. The aim of the study was to investigate the effect of (1→3), (1→6)-β-glucan on the production of interleukin 10 (IL-10) and tumor necrosis factor α (TNF-α) in vitro by peripheral blood leukocytes of patients with periodontitis. Material and Methods. In total, 20 patients suffering from untreated severe chronic generalized periodontitis were enrolled in this study. Periodontitis was confirmed by clinical and radiologic examination. Besides, 20 periodontally healthy patients served as a control group. Peripheral venous blood was sampled from the patients, and isolated leukocytes were treated with (1→3),(1→6)-β-glucan from yeast at different concentrations. The levels of IL-10 and TNF-α secreted by the leukocytes unstimulated and stimulated with unopsonized E. coli in vitro were determined by the enzyme amplified sensitivity immunoassay method. Results. Our data showed that (1→3),(1→6)-β-glucan induced a significant decrease (P<0.05) in the TNF-α level and a significant increase (P<0.001) in the IL-10 level in the media of unstimulated and stimulated leukocytes of the patients with periodontitis in comparison with those of the healthy subjects. Conclusions. The present in vitro study showed that (1→3),(1→6)-β-glucan modulated the response of leukocytes of the patients with periodontitis differently in comparison with those of the healthy subjects. It increased the release of IL-10, which is protective of the tooth-supporting tissues in patients with periodontal disease, but decreased the release of TNF-α, which is mainly responsible for the destruction of the tooth-supporting tissues during periodontal disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
