Feeding metformin during pregnancy and lactation periods improved learning and memory impairment in the rat offspring exposed to febrile seizure: Role of oxidative stress and inflammatory response
Background
Many clinical evidences have reported the higher risk of seizure in young children and infants after exposure to hyperthermia, which more likely can cause brain damage and affect cognitive function, so, many researches were focused on prevention or treatment of febrile seizure (FS) with minimal adverse effects. Considering the potential effects of oxidative stress as a prominent trigger in FS, and demonstrating the anti-oxidant effects of metformin, the present study aimed to investigate the protective effect of metformin administration in prenatal and lactation periods in rat pups exposed to hyperthermia by which induced seizure.
Method and materials
Pregnant rats were divided into six groups: (1) vehicle: pregnant rats received normal saline during pregnancy and lactation; (2) FS: pregnant rats received normal saline during pregnancy and lactation; (3–5) FS-Met50/100/150 mg/kg: pregnant rats received different doses of metformin including 50, 100 and 150 mg/kg during pregnancy and lactation; (6) Met150 mg/kg: pregnant rats received Met150 mg/kg during pregnancy and lactation. The male pups born to mothers received in all FS groups exposed to hyperthermia. All experimental groups were allowed to grow up, and after the lactation period, they were subjected for behavioural tests and biochemical analysis.
Results
According to the present findings, the prenatal and lactation exposure to the highest dose of metformin demonstrated significant difference with FS group in both behavioural and biochemical test analyses. Although the remaining doses of metformin were also effective, the much better results were reported with the highest dose of metformin (150 mg/kg). Interestingly, the highest dose of metformin administered alone demonstrated better result than vehicle in probe trial test.
Conclusion
Considering the present research and related study in relation to metformin in ameliorating the epilepsy symptoms, there are numerous evidences on positive effect of metformin on seizure. Although the exact mechanism is unclear, the anti-oxidant effect of metformin is strongly supported.
期刊介绍:
International Journal of Developmental Neuroscience publishes original research articles and critical review papers on all fundamental and clinical aspects of nervous system development, renewal and regeneration, as well as on the effects of genetic and environmental perturbations of brain development and homeostasis leading to neurodevelopmental disorders and neurological conditions. Studies describing the involvement of stem cells in nervous system maintenance and disease (including brain tumours), stem cell-based approaches for the investigation of neurodegenerative diseases, roles of neuroinflammation in development and disease, and neuroevolution are also encouraged. Investigations using molecular, cellular, physiological, genetic and epigenetic approaches in model systems ranging from simple invertebrates to human iPSC-based 2D and 3D models are encouraged, as are studies using experimental models that provide behavioural or evolutionary insights. The journal also publishes Special Issues dealing with topics at the cutting edge of research edited by Guest Editors appointed by the Editor in Chief. A major aim of the journal is to facilitate the transfer of fundamental studies of nervous system development, maintenance, and disease to clinical applications. The journal thus intends to disseminate valuable information for both biologists and physicians. International Journal of Developmental Neuroscience is owned and supported by The International Society for Developmental Neuroscience (ISDN), an organization of scientists interested in advancing developmental neuroscience research in the broadest sense.
