| Abstract | The current investigation was undertaken to determine the anti-inflammatory and antioxidant effects of Paederia foetida Linn. (PF) along with its mechanism of action when implemented in tissue protection. HPTLC was used in the identification of the compound quercetin, while in vitro analysis confirmed the significance of the antioxidant and anti-inflammatory action of PF. We initially demonstrated the in vivo anti-inflammatory effect of PF, evaluating it against a variety of phlogistic agents as well as turpentine oil, prostaglandin and arachidonic acid. Groups of rats, fasted overnight, were treated as follows: Group I: normal control (vehicle), Group II: PF (100 mg kg−1), Group III: arthritic control (CFA only, 0.05 ml), Group IV, V, VI: CFA (0.05 ml) + PF (25, 50 and 100 mg kg−1) and Group VII: CFA (0.05 ml) + indomethacin (10 mg per kg b.w.). PF significantly protected against paw edema, arthritic index and body weight alteration induced by Complete Fruend's Adjuvant (CFA). Other observations, like histological and macroscopic changes, were observed in CFA induced inflammation in knee joints. Subcutaneous administration of CFA was accompanied by proinflammatory cytokine status, as appraised by the amplification of interleukin-2 (IL-2), interleukin-1β (IL-1β) and tumor necrosis factor (TNF-α); oxidative stress status was estimated by the enhancement of the level of lipid peroxidation (LPO) and the depletion of superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione (GSH). Pre-treatment with PF significantly (P < 0.001) protected against CFA induced oxidative stress and proinflammatory cytokines. More prominently, CFA administration augmented tissue and plasma superoxide (O2) and hydrogen peroxide (H2O2) levels, while the PF pre-treatment significantly (P < 0.001) reversed all CFA induced intracellular interruption. Following CFA induced arthritis, PF was tested for its free radical scavenging activity against the DPPH and ABTS radicals and its inhibitory proficiency against COX-1 and COX-2 in vitro. Considering the above, the current research confirmed momentous protection against CFA induced arthritis, which could be attributed to its anti-inflammatory and pro-oxidant nature. |

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.
