Abstract (original English)

Background and objective Spinal cord injury (SCI) is a severe neurological disorder that leads to significant complications, including loss of bladder/bowel control and increased infection risk. The current standard treatment involves methylprednisolone administration and surgical decompression, but finding an effective therapy with minimal side effects remains a major challenge. This study aimed to investigate the effects of an optimized conditioned medium derived from rat adipose-derived mesenchymal stem cells (AD-MSCs) and dihydroepiandrosterone (DHEA) on behavioral indices, oxidative stress, stereological parameters, and histopathological outcomes in rats with compressive spinal cord injury (SCI). Material and methods In this study, 60 adult female rats were randomly divided into five groups: Sham group (laminectomy + intraperitoneal injection of 1 % dimethyl sulfoxide [DMSO], 200 µL for seven consecutive days), SCI-induced group (SCI induction + intraperitoneal injection of 1 % DMSO, 200 µL for seven consecutive days), Treatment group 1 (SCI induction + intraperitoneal injection of DHEA [30 mg/kg] dissolved in 1 % DMSO for seven consecutive days), Treatment group 2 (SCI induction + intraperitoneal injection of conditioned medium [200 µL] for seven consecutive days), Treatment group 3 (SCI induction + intraperitoneal injection of DHEA [30 mg/kg] dissolved in 1 % DMSO follow
