Abstract:
BACKGROUND: The mechanisms of spinal cord ischemia-reperfusion injury are the result of the combined effects of multiple factors, but there is no effective treatment.
OBJECTIVE: To investigate the effect of lipoxin receptor agonist BML-111 on inflammatory factor and apoptosis in rats with spinal cord ischemia-reperfusion injury.
METHODS: A total of 72 healthy adult male Sprague-Dawley rats were randomly divided into sham surgery group, ischemia-reperfusion group and BML-111 group. Rat models of spinal cord ischemia-reperfusion injury were established by clamping the abdominal aorta in the later two groups. Rats in the ischemia-reperfusion group and BML-111 group were injected with 0.1 mL of saline and 1 mg/kg BML-111 through caudal vein at 30 minutes after model establishment.
RESULTS AND CONCLUSION: Compared with ischemia-reperfusion group, BBB scores were significantly improved, pathological injury of spinal cord tissue significantly reduced, the number of apoptotic cel s, tumor necrosis factor α and interleukin-1β expression, myeloperoxidase oxide activity and malondialdehyde content decreased in the BML-111 group. These findings indicate that lipoxin receptor agonist BML-111 can inhibit neuronal apoptosis and inflammation so as to reduce spinal cord injury.
