摘要：In the middle cerebral artery occlusion model of ischemic injury, inlfammation primarily occurs in the infarct and peripheral zones. In the ischemic zone, neurons undergo necrosis and apop-tosis, and a large number of reactive microglia are present. In the present study, we investigated the pathological changes in a rat model of middle cerebral artery occlusion. Neuronal necrosis appeared 12 hours after middle cerebral artery occlusion, and the peak of neuronal apoptosis ap-peared 4 to 6 days after middle cerebral artery occlusion. Inlfammatory cytokines and microglia play a role in damage and repair after middle cerebral artery occlusion. Serum intercellular cell adhesion molecule-1 levels were positively correlated with the permeability of the blood-brain barrier. These ifndings indicate that intercellular cell adhesion molecule-1 may be involved in blood-brain barrier injury, microglial activation, and neuronal apoptosis. Inhibiting blood-brain barrier leakage may alleviate neuronal injury following ischemia.
