The Cerebral Circulation by Marilyn J. Cipolla Pdf

This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

On Disorders of the Cerebral Circulation by George Burrows Pdf

Excerpt from On Disorders of the Cerebral Circulation: And on the Connection Between Affections of the Brain and Diseases of the Heart The present volume does not pretend to be a complete treatise on the subjects which are discussed in its successive sections. The mass of the materials of which it is composed formed the substance of the Lumleian Lectures delivered at the Royal College of Physicians in the months of February and March 1843 and 1844. The first series of Lectures was afterwards published in the London Medical Gazette (May 1843). The physiological and pathological doctrines advanced in those lectures attracted the attention, and subsequent favourable notice, of many whose opinions the author highly valued.

The Human Brain Circulation by Rosemary D. Bevan,John A. Bevan Pdf

Much of our knowledge of the cerebral circulation has been derived from studies of species other than human. There is increas ing recognition of species differences and concern that studies in animals may be misleading if unquestioningly applied to the human. A dramatic example of this occurred in the early his tory of the study of the circulation of the brain. Galen of Pergamo (131-201 AD) described a rete mirabile or "marvelous network" of blood vessels at the base of the human skull that he must have derived from observations of certain animals. This vascular structure was supplied by the carotid arteries which, after penetrating the cranium,"are divided into a large number of very small and thin branches in the region between the cranium and the dura matter. Then . . . intersecting one another they give the impression of having forgotten their way in the brain. But this is not the case. In fact, these numerous arteries rejoin and unite like the roots of a tree trunk. . . . " The authority of Galen's writings dominated scientific thought for about 1500 years. His description of a rete was unques tioned by Leonardo de Vinci, who included it in his anatomical sketches. William Harvey's remarkable observations led to his definitive account of the circulation of blood.

Cerebral Blood Flow by Mario Brock,C. Fieschi,D. H. Ingvar,N. A. Lassen,K. Schürmann Pdf

This book is a survey of some aspects of current knowledge on regional Cerebral Blood Flow (rCBF), mainly as studied by the isotope clearance method. Although both theoretical and methodological problems are discussed, attention is mainly dedicated to data obtained from clinical studies. The papers which make up this book were presented at the International Symposium on the Clinical Applications of Isotope Clearance Measurement of Cerebral Blood Flow, held in Mainz, Western Germany, on April 10-12, 1969. The previous meetings on Cerebral Blood Flow, held in Lund in 1964* and in Lund and Copenhagen 1968**, had shown that the moment had come to concentrate on the possibilities of introducing rCBF measurements into clinical routine. This is why in the Mainz Symposium attention was initially focused on methodological aspects. This is also why theoretical problems of physiology of CBF were not emphasized. Finally, this explains why such topics as cerebrovascular disease, head trauma, coma, carotid surgery, brain tumors and intracranial pressure were given pride of place. However a survey of the clinical aspects of rCBF measurements would not be complete without an account of the application of such measurements to monitor cerebral circulatory changes during anesthesia and therapeutic procedures like, for instance, hyperventilation and hyperbaric treatment. Furthermore, it is now possible to obtain data from correlative rCBF studies per formed before, during and after surgical operations on the human brain.

Stimulated Cerebral Blood Flow by Peter Schmiedek,Karl Einhäupl,Carl-Martin Kirsch Pdf

Das vorliegende Buch enth{lt die Beitr{ge eines internatio- nalen Symposiumszum Thema "Stimulierte Hirndurchblutung". Vorgestellt werden zun{chst neue Erkenntnisse zur Regulation der Hinrdurchblutung. Im 2. Abschnitt kommen verschiedene Methoden zur Messung der Hirndurchblutung zur Sprache, die sowohl unter experimentellen als auch unter klinischen Be- dingungengetestet wurden. Es folgt ein Abschnitt, der ver- schiedene M|glichkeiten zur Stimulation der Hirndurchblutung aufzeigt. Im letzten Abschnitt wird aufdie Bedeutung der stimulierten Hirndurchblutungsmessung zur Bestimmung der ce- rebrovascul{ren Reservekapazit{ten hingewiesen. Dieser Para- meter hat nach den vorliegenden Untersuchungen klinisch- praktische Bedeutung, beispielsweise f}r die Indikations- stellung bei cerebrovascul{ren Eingriffen zur Isch{mie-Pro- phylaxe.
