| Abstract | Plants with antidiabetic activities provide important source for the development of new drugs in the management of diabetes mellitus. The main aim of this study was to evaluate the protective effect of aqueous extract (AE) of Pimpinella tirupatiensis (Pt) tuberous root on cardiac oxidative stress and lipid peroxidation (LPO) in non-diabetic and streptozotocin (STZ)-induced diabetic rats. Diabetes was induced in male Wistar rats by a single administration of STZ (40 mg/kg intraperitoneal (i.p). AE (750 mg/kg/b.w./day) and glibenclamide (GLB) (20 mg/kg/b.w./day) were administrated orally by intra oral gastric tube for 30 days. After 4 weeks of hyperglycaemia the enzymatic and non-enzymatic factors were measured in cardiac tissue of diabetic and control groups. Xanthine oxidase activity (XOD), Uric acid (UA) and malondialdehyde (MDA) content were significantly (p<0.01) elevated by 48, 48 and 50% respectively and the contents of glutathione (GSH), ascorbic acid (AA) were significantly (p<0.01) diminished by 45 and 42% respectively in diabetic rats when compared to normal. Treatment with AE and GLB normalized the content of UA, GSH, AA, MDA and the activity of XOD. No significant changes were observed in control rats treated with AE. This data suggests that hyperglycemia induces oxidative stress in the heart, but the oxidative stress defense mechanisms in the heart tissue are fairly efficacious against oxidative injury by the treatment with AE and GLB. The present study reveals that AE may provide a useful therapeutic option in the reversal of oxidative stress induced cardiac dysfunction in diabetes mellitus. |

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.
