Effectiveness of Radish (Raphanus sativus) Extract In Reducing Tnf-α and Nitrit Oxida levels in Tipe II DM Mice Models with Traumatic Brain Injury

Introduction: The devastating effects of traumatic brain injury (TBI) are fatal, and there is no effective treatment for primary brain injury, especially in patients with diabetes mellitus (DM). Nitric oxide (NO) is a compound that causes systemic vasodilation; a decrease in NO reduces cerebral blood flow after TBI. There is an increase in TNF-α levels demonstrated by mononuclear cells surrounding the traumatic lesion in the rat brain. Raphanus sativus (radish) is a root vegetable belonging to the Brassicaceae family, which has anti-diabetic effects by lowering blood glucose levels, reducing lipid peroxidation, and improving brain function, thereby protecting against neurotoxic effects associated with oxidative stress in experimental mouse models. Objective: To evaluate the efficacy of radish extract (Raphanus sativus) in reducing TNF-α and nitric oxide levels in a rat model of type II diabetes mellitus with traumatic brain injury. Method: This study was an in vivo laboratory experimental study with a post-test only control group design. The study population consisted of 25 Wistar rats, which were then induced with diabetes and subjected to a modified Feeney Model closed head injury. After complete data collection, KGD and ELISA assessments were performed, followed by data analysis. Results: There were significant differences (p<0.05) in serum NO and serum TNF-α levels between the normal group, the 100 mg/kg radish extract group, the 300 mg/kg radish extract group, and the 500 mg/kg radish extract group compared to the negative control group. This indicates that radish extract, starting at a dose of 100 mg/kg, can reduce serum NO and serum TNF-α levels. Conclusion: Radish extract (Raphanus sativus) is effective in reducing TNF-α and nitric oxide levels in a Wistar rat model of type II DM with traumatic brain injury.
