Here, we show that fluoxetine inhibits apoptotic cell death of hippocampal neuron and memory impairment by blocking BBB disruption after transient global ischemia. Fluoxetine treatment (10 mg/kg) after global ischemia significantly inhibited mRNA expression of MMP-2 and -9 and reduced MMP-9 activity. By Evan blue assay, fluoxetine reduced ischemia-induced BBB permeability. In parallel, fluoxetine significantly attenuated the loss of occludin and laminin in the hippocampal area after ischemia. By immunostaining with occludin antibody, fluoxetine preserved the integrity of vascular networks, especially in hippocampal areas after injury. Fluoxetine also prevented the infiltration of macrophages and inhibited the mRNA expression of inflammatory mediators after injury. In addition, the activation of microglia and astrocyte in hippocampal regions was significantly attenuated by fluoxetine. Finally, fluoxetine reduced apoptotic cell death of hippocampal neurons as well as vascular endothelial cell death and improved learning and memory. Thus, our study suggests that the neuroprotective effect of fluoxetine is likely mediated by blocking MMP activation followed BBB disruption after transient global ischemia, and the drug may represent a potential therapeutic agent for preserving BBB integrity following ischemic brain injury in humans.

- Risk Factors of Hematomyelia Recurrence and Clinical Outcome in Children with Intradural Spinal Cord Arteriovenous Malformations.

- High cervical arteriovenous fistulas fed by dural and spinal arteries and draining into a single medullary vein.
- Onda K1, Yoshida Y, Watanabe K, Arai H, Okada H, Terada T.Author information 1Department of Neurosurgery, Niigata Neurosurgical Hospital, Yamada, Niigata; and.AbstractObject The authors previously reported a case of complex arteriovenous fistula (AVF) at C-1 with multiple dural and spinal feeders that were linked with a common medullary venous channel. The purpose of the present study was to collect similar cases and analyze their angioarchitecture to gain a better understanding of this malformation. Methods Three such cases, affecting 2 males and 1 female in their 60s who had presented with hematomyelia (2) or progressive myelopathy (1), were treated surgically, and the operative findings from all 3 cases were compared using digital subtraction angiography (DSA) to determine the angioarchitecture. Results The C-1 and C-2 radicular arteries and anterior and posterior spinal arteries supplied feeders to a single medullary draining vein in various combinations and via various routes. The drainage veins ran along the affected ventral nerve roots and lay ventral to the spinal cord. The sites of shunting to the vein were multiple: dural, along the ventral nerve root in the subarachnoid space, and on the spinal cord, showing a vascular structure typical of dural AVF, that is, a direct arteriovenous shunt near the spinal root sleeve fed by one or more dural arteries and ending in a single draining vein, except for intradural shunts fed by feeders from the spinal arteries. In 2 cases with hemorrhagic onset the drainer flowed rostrally, and in 1 case associated with congestive myelopathy the drainer flowed both rostrally and caudally. Preoperative determination of the shunt sites and feeding arteries was difficult because of complex recruitment of the feeders and multiple shunt sites. The angioarchitecture in these cases was clarified postoperatively by meticulous comparison of the DSA images and operative video. Direct surgical intervention led to a favorable outcome in all 3 cases. Conclusions A high cervical complex AVF has unique angioarchitectural characteristics different from those seen in the other spinal regions.
