| Abstract | This study aimed to investigate the effect of total flavonoids of Choerospondias axillaris (TFC) on myocardial infarction (MI)-induced cardiac dysfunction, interstitial fibrosis and inflammatory reaction and further to clarify the potential signaling pathway involved. Rats were subjected to MI via coronary artery occlusion. The model establishment was confirmed by the occurrence of ST-segment elevation in electrocardiogram. Then, TFC was administrated at doses of 75, 150 and 300 mg/kg for 28 consecutive days (gavage). Body weight and heart weight were recorded. Hemodynamics, infarct size and myocardial fibrosis were examined. Blood samples were collected to determine tumor necrosis factor-α (TNF-α) and interleukin 6, 10 (IL-6, IL-10) levels. The expressions of matrix metalloproteinases-2, 9 (MMP-2, 9), phosphor-IKBα (p-IKBα) and transforming growth factor-β1 (TGF-β1) were assayed by Western blot. The results indicated that TFC significantly improved cardiac dysfunction, the heart coefficient and myocardial fibrosis in MI rat. TFC also decreased the levels of TNF-α and IL-6, but increased IL-10 content. Moreover, treatment with TFC protected the heart from chronic MI injury by decreasing the expressions of MMP-2, 9, TGF-β1 and p-IKBα. The results suggested that TFC attenuated cardiac dysfunction and myocardial interstitial fibrosis by modulating nuclear factor-kappa B (NF-κB) signaling pathway. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
