Opis

Because stroke is essentially a disease of the vessels and blood flow, the most fundamental aspects of ischemic blood flow in the brain are under investigation by researchers. Their work was the focus of the sixth in the series of Keio University International Symposia for Life Sciences and Medicine, held in Tokyo in 1999. Selected here are 55 papers from the symposium, covering the buffy coat (glycocalyx) of endothelial cells, the blood-brain barrier and permeability, gene expression, vascular reactivity, dysregulation, inflammatory deterioration, cortical spreading depression, edema, microvascular derangement, and pathology, in ten major sections. The book includes the thought-provoking discussions that followed the presentations, thus providing an invaluable source of up-to-date information not only for researchers investigating microcirculation but also for clinicians implementing the most effective treatment for stroke patients.
