| Abstract | Lamotrigine is an anticonvulsant and has an antiglutamatergic action, which may contribute to its antidepressant effects, since glutamate has been linked to depression. The purpose of the present study was to investigate the behavioral and molecular effects of lamotrigine treatment in maternally deprived rats. To this aim, deprived and non-deprived male rats were treated with lamotrigine (20 mg/kg) once a day for 14 days during their adult phase. Their behavior was then assessed in the forced swimming and open field tests. In addition to this, the BDNF and NGF levels were assessed in the prefrontal cortex, hippocampus and amygdala. In the course of this study we demonstrated that maternally deprived rats treated with saline and lamotrigine showed an increase in their immobility time and a decrease in the climbing and swimming times when compared with non-deprived rats treated with saline alone. Treatment with lamotrigine reversed the increase in the immobility time in the deprived rats. The BDNF levels were decreased in the amygdala in deprived rats treated with saline, and treatment with lamotrigine reversed this decrease. The NGF levels were decreased in the hippocampus in deprived rats treated with saline, but treatment with lamotrigine did not reverse this decrease. In conclusion, lamotrigine showed antidepressant effects in the forced swimming test, and it presented positive effects on the BDNF protein levels in the amygdala of maternally deprived rats. |

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.
