Subarachnoid hemorrhage (SAH) results in significant long-lasting cognitive dysfunction. Therefore, evaluating acute and long-term outcomes after therapeutic intervention is important for clinical translation. The aim of this study was to use minocycline, a known neuroprotectant agent, to evaluate the long-term benefits in terms of neurobehavior and(More)
The blood-brain barrier (BBB) disruption and brain edema are important pathophysiologies of early brain injury after subarachnoid hemorrhage (SAH). This study is to evaluate whether Rho kinase (Rock) enhances BBB permeability via disruption of tight junction proteins during early brain injury. Adult male rats were assigned to five groups; Sham-operated, SAH(More)
The aim of this study was to evaluate whether sampling of cerebrospinal fluid (CSF) via the cisterna magna and of blood via the heart affects brain water content in a rat subarachnoid hemorrhage (SAH) model. Twenty-nine animals were divided into four groups: sham-operated group with sampling of CSF and blood (Sham S+), sham-operated group without sampling(More)
Hypoxia inducible factor (HIF)-1α is the central transcriptional factor for the regulation of oxygen-associated genes in response to hypoxia. Erythropoietin (EPO), a hematopoietic growth factor, increases oxygen availability during hypoxia/ischemia and is associated with neuroprotection following hypoxia–ischemia in laboratory models of stroke. However, EPO(More)
Several reports indicate that the activity of the hypothalamic–pituitary–adrenal axis (HPA) is increased after a brain insult and that its down-regulation can improve detrimental outcomes associated with ischemic brain injuries.Granulocyte-colony stimulating factor (G-CSF) is a neuroprotective drug shown in the naïve rat to regulate hormones of the HPA(More)
PURPOSE Sodium orthovanadate (SOV) is a representative tyrosine phosphatase inhibitor and has been shown to ameliorate neuronal injury in cerebral ischemia. We hypothesized that tyrosine phosphatase inhibition by SOV might attenuate early brain injury after subarachnoid hemorrhage (SAH) in this study. METHODS The endovascular perforation model of SAH was(More)
BACKGROUND Middle cerebral artery aneurysms (MCA aneurysms) belong to the most frequent type of intracranial aneurysms forming an intracerebral hematoma. The consequences of the hematoma-the laterality, the impact of ICH volume and size of the aneurysm with the final outcome of these patients had not been studied in detail in this location, and we focused(More)
