DOI : 10.9775/kvfd.2023.29955 Sleep contributes to the energy balance of body. This study aims to investigate how rapid eye movement (REM) sleep deprivation (SD) or recovery sleep affects rat weight and the serum levels of Nesfatin-1, Orexin-A, and Leptin; additionally, seeks to determine the impact of melatonin administration on these parameters. Male, Sprague Dawley rats were randomized into two groups (n=9). REMSD was induced using the modified multiple platform method (MMPM). Melatonin was used as a treatment (20 mg/kg). Study Group I was created to investigate the effectiveness of the treatment during REMSD. Study Group II was established to analyze the possible therapeutic role of melatonin and recovery sleep after REMSD-induced damage. The rats" weights were recorded during the experiments. Blood samples were collected from all rats via decapitation after experiments. The levels of serum Nesfatin-1, Orexin-A, and Leptin were analyzed using the ELISA method. REMSD affected weight of the rats and altered the levels of serum Nesfatin-1 and Leptin. Melatonin administration influenced weight gain and affected Nesfatin-1 and Leptin levels. REMSD or melatonin did not affect Orexin-A levels. REMSD and melatonin play significant roles in the body"s energy balance. This study will contribute to elucidating the role of SD in metabolic processes and will play a role in assessing the impact of melatonin, a commonly used treatment in human and veterinary medicine.
