  1. 1. Pathophysiology of blood-brain barrier, brain edema and cell injury following hyperthermia : New role of heat shock protein, nitric oxide and carbon monoxide : an experimental study in rat using light and electron microscopy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hari Shanker Sharma; Uppsala universitet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; blood-brain barrier; heat stress; hyperthermia; brain edema; serotonin; nitric oxide; carbon monoxide; heat shock protein; glial fibrillary acidic protein; myelin basic protein; opioids; histamine; catecholamines; naloxone; indomethacin; p-CPA; electron microscopy; immunocytochemistry; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; Human Anatomy; anatomi;

    Abstract : This thesis deals with the molecular mechanisms of hyperthermia induced brain damage in rats. The results clearly establish that hyperthermia caused by 4 h heat stress at 38° C is associated with a breakdown of the blood-brain barrier (BBB) permeability which seems to be instrumental in causing brain edema and cell injury.

  3. 3. Effects of Rho kinase, prostacyclin and L-arginine on microvascular permeability and perfusion

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Cornelia Lundblad; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; skeletal muscle; Rho kinase; prostacyclin; permeability; NO; experimental brain trauma; brain edema; brain contusion; microcirculation; cerebral perfusion;

    Abstract : This thesis presents some effects of Rho kinase, prostacyclin (PGI2) and nitric oxide (NO) in relation to trauma and inflammation by evaluating their effects on microvascular perfusion and permeability in mouse brain and in cat skeletal muscle. PGI2 and NO are endogenous vasoactive substances produced by the endothelium. READ MORE

  4. 4. Cerebral circulation and the sympathetic nervous system in patients with traumatic brain injury or subarachnoid hemorrhage

    University dissertation from Göteborg

    Author : Silvana Naredi; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; brain edema; microcirculation; intracranial pressure; epo-prostenol; norepinephrine; subarachnoid hemorrhage; sympathetic nervous system; clonidine;

    Abstract : Maintenance of adequate cerebral microcirculation is necessary to avoid cerebral ischemia after severe traumatic brain injury and non-traumatic subarachnoid hemorrhage. After severe traumatic brain injury the blood-brain-barrier is disrupted and transcapillary leakage will contribute to the development of vasogenic brain edema. READ MORE

  5. 5. Transvascular fluid exchange with application to the brain. An experimental study in cat skeletal muscle and brain

    University dissertation from Department of Anaesthesiology and Intensive Care, Lund

    Author : Lis Kongstad; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; neuropsychology; Neurology; intensivvård; capillary filtration coefficient; Capillary permeability; reflection coefficient; brain edema; dural puncture; Anaesthesiology; Anestesiologi; intensive care; neuropsykologi; neurofysiologi;

    Abstract : This study evaluated transcapillary fluid exchange in the cat brain and in a cat skeletal muscle enclosed in a plethysmograph. A method for determination of capillary permeability (capillary filtration coefficient and reflection coefficient) and effects of transcapillary hydrostatic pressure changes were studied We found that capillary fluid permeability in a tissue can be determined by the capillary filtration coefficient, even when arterial pressure and vascular tone are changed.
