| Abstract | AIM: Hepatotoxicity is a significantly increasing health problem worldwide, and the extent of the problem has stimulated interest in the search for hepatotherapeutic agents from plants. This study investigated the hepatoprotective and in vivo antioxidant activities of the hydroethanolic extract of Mucuna pruriens leaves in antitubercular and alcohol-induced hepatotoxicity assays in rats. METHOD: In each of the models used, seven groups were allotted. The different groups received normal saline (10 mL·kg(-1), p.o.); hepatotoxicant (isoniazid-rifampicin, INH-RIF, 100 mg·kg(-1), i.p. or 20% ethanol 5 g·kg(-1), p.o.) and normal saline (10 mL·kg(-1), p.o.); hepatotoxicant and extract at doses of 100, 200, and 400 mg·kg(-1) p.o.; hepatotoxicant and silymarin 50 mg·kg(-1) p.o.; and extract at 400 mg·kg(-1) p.o. On the 21(st) day of treatment, blood was collected for assessment of serum biochemical parameters and harvested liver samples were assessed for antioxidants. RESULTS: The hepatotoxicants significantly (P < 0.05-0.001) increased the levels of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), bilirubin, and malondialdehyde (MDA); and reduced the levels of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and reduced glutathione GSH compared to control. M. pruriens significantly reversed (P < 0.05-0.001) the elevation in the level of ALT, AST, ALP, and bilirubin caused by the hepatotoxicants. The extract (200 and 400 mg·kg(-1)) significantly reversed (P < 0.05) the diminution in the level of in vivo antioxidants and increased the level of MDA produced by INH-RIF. M. pruriens (100-400 mg·kg(-1)) elicited significant reduction (P < 0.001) in the level of MDA compared to the alcohol group. Silymarin also reversed the deleterious effects of the hepatotoxicants. CONCLUSION: The hydroethanolic extract of Mucuna pruriens leaves possesses hepatoprotective activity with enhancement of in vivo antioxidants as a possible mechanism of action. |

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.
