It is considered controversial whether superficial temporal artery (STA)-middle cerebral artery (MCA) bypass affects the outcome of patients with ischemic stroke. This prospective study was undertaken to demonstrate the effect of STA-MCA bypass on the cerebral blood flow and neurological status of the patients with ischemic stroke. Seventy-five patients(More)
PURPOSE To elucidate the distribution of improved pain and numbness after cervical decompression surgery in patients with cervical spine disorders. METHODS This study included 4 men and 5 women aged 45 to 71 years(mean 58 years)presenting with radiculopathy and 50 men and 17 women aged 35 to 88 years(mean 66 years)presenting with myelopathy. RESULTS All(More)
Sporozoites of Leucocytozoon caulleryi were inoculated into specific-pathogen-free (SPF) chickens intravenously. Fourteen days after inoculation, the infected blood, parasitized with second generation merozoites, was collected from the chickens. The blood was then suspended in SPF chicken serum or RPMI-1640 culture medium supplemented with 20% SPF chicken(More)
OBJECT Tenascin-C (TNC), a matricellular protein, is induced in the brain following subarachnoid hemorrhage (SAH). The authors investigated if TNC causes brain edema and blood-brain barrier (BBB) disruption following experimental SAH. METHODS C57BL/6 wild-type (WT) or TNC knockout (TNKO) mice were subjected to SAH by endovascular puncture. Ninety-seven mice(More)
Accumulated evidence suggests that blood-brain barrier disruption or brain edema is an important pathologic manifestation for poor outcome after aneurysmal subarachnoid hemorrhage. Many molecules may be involved, acting simultaneously or at different stages during blood-brain barrier disruption via multiple independent or interconnected signaling pathways.(More)
BACKGROUND AND PURPOSE A matricellular protein tenascin-C is implicated in early brain injury after experimental subarachnoid hemorrhage (SAH). This study first evaluated the role of another matricellular protein periostin and the relationships with tenascin-C in post-SAH early brain injury. METHODS Wild-type (n=226) and tenascin-C knockout (n=9) C57BL/6(More)
OBJECTIVE Chronic hydrocephalus develops in association with the induction of tenascin-C (TNC), a matricellular protein, after aneurysmal subarachnoid hemorrhage (SAH). The aim of this study was to examine if cilostazol, a selective inhibitor of phosphodiesterase Type III, suppresses the development of chronic hydrocephalus by inhibiting TNC induction in(More)
Toll-like receptor 4 (TLR4) signaling may play a crucial role in the occurrence of cerebral vasospasm after subarachnoid hemorrhage (SAH). The main purpose of this study was to assess if selective blockage of TLR4 on cerebral arteries prevents cerebral vasospasm development and neurological impairments after SAH in mice. One hundred fourteen mice underwent(More)
A matricellular protein tenascin-C (TNC) has been suggested to play a role in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH), but the direct evidence remains lacking. In this study, we examined effects of TNC knockout (TNKO) on cerebral vasospasm after experimental SAH in mice. C57BL/6 wild-type (WT) or TNKO mice were subjected(More)
