| Abstract | Ginsenoside Rg1 is the primary active substance in ginseng, and it has multiple pharmacological actions. Investigations on the pharmacologic action of ginsenoside Rg1 have developed, with a particular focus on the regulation of metabolism. The present study hypothesized that the neuroprotective effects of ginsenoside Rg1 prevent cognitive impairment induced by isoflurane anesthesia via antioxidant, antiinflammatory and antiapoptotic effects, mediated by the phosphoinositide 3kinase (PI3K)/AKT/glycogen synthase kinase3ß (GSK3ß) pathway in aged rats. SpragueDawley rats were divided into isoflurane and ginsenoside Rg1 groups and were treated with 20 mg/kg ginsenoside Rg1 for 7 days. Morris water maze was performed to analyze the cognitive function of the rats. Enzymelinked immunosorbent assays were used to analyze the levels of malondialdehyde, glutathione, interleukin (IL)1ß, IL6 and caspase 3. The protein expression levels of AKT, GSK 3ß, p21WAF1/CIP1 and p53 were measured using western blot analysis. Ginsenoside Rg1 significantly improved cognitive function, and exhibited antioxidant and antiinflammatory effects, demonstrating the neuroprotective effects of ginsenoside Rg1 against the effect of isoflurane anesthesia in the rats. In addition, ginsenoside Rg1 significantly reduced caspase3 activity, upregulated the expression of PI3K/AKT/GSK3ß and downregulated the mRNA expression levels of p21WAF1/CIP1 and p53 in the aged rats exposed to isoflurane anesthesia. The data obtained in the present study provided evidence that the neuroprotective effects of ginsenoside Rg1 prevented the cognitive impairment induced by isoflurane anesthesia via antioxidant, antiinflammatory and antiapoptotic effects, mediated by the PI3K/AKT/GSK3ß 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.
