Aging alters the vascular response to extracellular nucleotides. However, the molecular mechanisms that underlie the effect of aging remain unclear. We investigated the mRNA expression of P2X(1), P2Y(1), P2Y(2) subtypes of the nucleotide receptors (P2) in the basilar artery, aorta and carotid artery from male Sprague-Dawley rats, 2-months and 19-months old.… (More)
We have reported a case of primary interhemispheric subdural hematoma with successful surgical removal. Paresis of the lower extremity out of proportion to the arm and face may provide a clue to the location of the lesion. Although CT is the most valuable single diagnostic procedure, carotid angiography is needed to exclude a vascular lesion.
BACKGROUND Acute hydrocephalus (HCP) after aneurysmal subarachnoid hemorrhage (SAH) often persists. Our previous study described factors that singly and combined in a formula correlate with permanent CSF diversion. We now aimed to determine whether the same parameters are applicable at an institution with different HCP management practice. METHODS We… (More)
We have reported a case of acute spinal epidural abscess, an uncommon cause of pain in the neck and back. The typical progression from spinal ache to paralysis may be halted if the diagnosis is suspected and prompt radiologic and surgical interventions are initiated.
Cervical myelography by lumbar run-up produces excellent radiologic studies in most cases. Use of this technique avoids the hazards and pitfalls associated with a lateral cervical puncture. We discuss 92 cases, with excellent or good results in 98% and nondiagnostic studies in only 2%. Both of the poor technical studies were followed by computed tomographic… (More)
