Expressional Changes in Cerebrovascular Receptors after Experimental Transient Forebrain Ischemia

BACKGROUND Global ischemic stroke is one of the most prominent consequences of cardiac arrest, since the diminished blood flow to the brain results in cell damage and sometimes permanently impaired neurological function. The post-arrest period is often characterised by cerebral hypoperfusion due to subacute hemodynamic disturbances, the pathophysiology of which are poorly understood. In two oth...

Ischemia detection from morphological QRS angle changes.

In this paper, an ischemia detector is presented based on the analysis of QRS-derived angles. The detector has been developed by modeling ischemic effects on the QRS angles as a gradual change with a certain transition time and assuming a Laplacian additive modeling error contaminating the angle series. Both standard and non-standard leads were used for analysis. Non-standard leads were obtaine...

Intensification of brain injury and blood-brain barrier permeability by short-term hypertension in experimental model of brain ischemia/reperfusion

Introduction: Arterial hypertension is one of the causes of stroke, and as one of the vasculotoxic conditions intensifies ischemic stroke complications. The aim of the present study was to analyze the effects of short-term cerebral hypertension on ischemia/reperfusion injury and pathogenesis of ischemic stroke. Methods: The experiments were performed on three groups of rats (N=36) Sham, cont...

Morphological responses of cerebral tissues to temporary ischemia.

The ultrastructural responses of cerebral tissue following temporary periods (1/2, 1,2,3, or 4 hour) of right, middle cerebral artery, (MCA) occlusion were studied acutely after a 3 day or 7 day interval following the removal of the MCA clip. Cortical and basal ganglia tissues for each ischemic duration were compared at 3 post-occlusive periods (acute, 3 days, 7 days). With the short periods of...

Blood-brain barrier disturbances and morphological changes in rat brain after photochemically induced focal ischaemia.

The disturbances in cerebral circulation lead to focal brain ischaemia and brain infarcts. The pathogenesis of brain ischaemia has been a subject of numerous experimental studies employing different models and focusing on the anatomy of collateral circulation. The aim of this study was the evaluation of our own model of focatcerebral damage caused by a photodynamic reaction, and determination o...
