| Abstract | Neuroinflammation is an innate immune response in the central nervous system (CNS) against metabolic and pathogenic toxic wastes. The main hypothesis implies that a state of hyperammonemia which is accountable for both direct and indirect modification in ammonia metabolism with an elevated production of inflammatory cytokines. This study was constructed to explore the modulating effect of chrysin on rudimentary pathophysiologic mechanisms of ammonium chloride (NH Cl) mediated neuroinflammation in the experimental hyperammonemic rats. NH Cl was injected intraperitonally (i.p) in male albino wistar rats for a time period of thrice a week for eight consecutive weeks. Initially, the levels of brain ammonia and water content were assessed. Immunohistochemical, RT-PCR and western blotting analysis revealed that the expression of glutamine synthetase (GS) activity and glial fibrillar acidic protein (GFAP) were down-regulated, whereas the expression of TNF- , IL-1ß, IL-6, p65 NF-κB, iNOS and COX-2 were up-regulated in brain tissue of hyperammonemic rats. Oral supplementation of chrysin (100mg/kg b.w) to hyperammonemic rats considerably restored the levels of brain ammonia, water content, and the expressions of GS, GFAP, TNF- , IL-1ß, IL-6, p65 NF-κB, iNOS and COX-2. Our findings provided substantial evidence that the chrysin synergistically attenuating the neuroinflammatory mechanism by repressing the expression of proinflammatory cytokines and up-regulating the astrocytic protein expressions via ammonia-reducing strategies. This data suggests that chrysin effectively acts as a therapeutic agent to treat hyperammonemia mediated neuroinflammation. |

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.
