| 1 | A comparative study on the antioxidant activity of methanolic leaf extracts of Ficus religiosa L,Chromolaena odorata(L.) King & Rabinson,Cynodon dactylon(L.) Pers.and Tridax procumbens L.显示文摘Objective:To compare the antioxidative effects of the methanolic leaf extracts of Ficus religiosa (F.religiosa),Chromolaena odorata(C.odorata),Cynodon dactylon(C.dactylon) and Trida,x procumbens(T.procumbens) as well as the contents of antioxidants in the extracts.Methods: Total phenol and total flavanoid contents were measured according to the standard procedures. The total antioxidant capacity was determined using the phosphomolybdenum method.Reducing power was determined by the potassium ferrieyanide reducing method.The free radical scavenging activity was measured by 2,2’-Diphenyl-l-picrylhydrazyl(DPPH) assay.Results: Quantitative phytochemical analysis of total phenol content showed that C.odorata had the highest content of phenolic compounds significantly followed by F.religiosa,T.procumbens and C.dactylon.As for the total flavanoids content,F.religiosa had the highest content,followed by C.odorata,T.procumbens and C.daxtylon.Study on the total antioxidant capacity revealed that F.religiosa,C.dactylon and C.odorata showed higher total antioxidant capacity.T.procumbens showed the lowest capacity.Meanwhile,T.procumbens and C.odorata have the highest reducing power activity followed by F.religiosa and C.dactylon.The results of DPPH radical scavenging activity indicated that T.procumbens induced the largest elevation as the concentration of its extract increased,followed by C.odorata and F.religiosa and C.dactylon.Conclusions:The present study demonstrates the antioxidative capacity of all the four plant species.Of all the plants,C.odorata,a perennial weed plant showed potentially a high antioxidant activity,with higher phenolic and flavonoids contents.The data suggest that C.odorata can be best utilized in developing bioantioxidants. | Melinda Krishanti P Xavier Rathinam Marimuthu Kasi Diwakar Ayyalu Ramanathan Surash Kathiresan Sadasivam Sreeramanan Subramaniam | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，5： | 6 |
| 2 | Unexpected alliance between syndecan-1 and innatelike T cells to protect host from autoimmune effects of interleukin-17显示文摘Innate-like T cells, namely natural killer T(NKT) and γδ T cells, play critical roles in linking innate and adaptive immune responses through rapid production of cytokines. Prominent among these cytokines is interleukin-17(IL-17), which is a potent proinflammatory cytokine that plays a critical role in host defense against fungi and extracellular bacteria. However, excessive IL-17-production promotes autoimmune diseases, including psoriasis, multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, and systemic lupus erythematosus. IL-17 has also been implicated in regulating body fat, which is highly relevant given rises in obesity and type 2 diabetes. NKT cells, γδ T cells and mucosal-associated invariant T cells(MAIT) are the major sources of IL-17 involved in protection of mucosal surfaces from opportunistic infections and causing autoimmunity when become dysregulated. Given the pathogenic effects of IL-17, efforts have been directed towards understanding mechanisms that guard against IL-17 overproduction. One novel potent mechanism is mediated by the heparan sulfate proteoglycan, syndecan-1(sdc1), which is selectively expressed by IL-17-producing subsets of NKT and γδ T cells. This unexpected role for sdc1 is uncovered by analysis of NKT and γδ T cells in sdc1-deficient mice. In this mini-review, we discuss selective expression of sdc1 by these innate T cells and consequences of its absence on IL-17 homeostasis and pathological implications. | Anil Kumar Jaiswal Mohanraj Sadasivam Abdel Rahim A Hamad | 2018 | World Journal of Diabetes2018，9，12： | 5 |
