Abstract
Background: Subarachnoid hemorrhage (SAH) is a major form of hemorrhagic stroke. It is not known whether remote ischemic postconditioning (RIP), a promising method to induce neuroprotection, can improve neurological outcome after SAH. Methods: SAH was induced by endovascular perforation of a right cerebral artery in adult Sprague-Dawley male rats. RIP was performed 5 minutes later by three cycles of 10 minutes ischemia and 10 minutes reperfusion to the bilateral legs. Results: SAH reduced neurological scores, induced brain edema and increased blood-brain barrier permeability. RIP did not affect the neurological scores and brain edema but partly inhibited the increase of blood-brain barrier permeability after SAH. Conclusions: These results suggested that RIP may not significantly induce neuroprotection against SAH. Citation: Yun-Zhen Wang, Ru-Quan Han, Zhi-Yi Zuo.
