Ultrastructural alterations of human cortical capillary basement membrane in human brain oedema.
The capillary basement membranes are examined in severe traumatic brain injuries, vascular malformation, congenital hydrocephalus and brain tumours. They exhibit homogeneous and nodular thickening, vacuolization, rarefaction, reduplication, and deposition of collagen fibers. Their average thickness varied according to the aetiology and severity of brain oedema. In moderate brain oedema the thic...
متن کاملMathematical modelling of blood-brain barrier failure and oedema.
Injuries such as traumatic brain injury and stroke can result in increased blood-brain barrier (BBB) permeability. This increase may lead to water accumulation in the brain tissue resulting in vasogenic oedema. Although the initial injury may be localized, the resulting oedema causes mechanical damage and compression of the vasculature beyond the original injury site. We employ a biphasic mixtu...
متن کاملEffect of methylprednisolone on the axonal impairment accompanying cellular brain oedema induced by water intoxication in rats.
OBJECTIVES Our previous experiments proved that methylprednisolone (MP) can significantly reduce axonal impairment accompanying extracellular oedema induced by the osmotic challenge (load) on the blood-brain barrier (BBB). The aim of the present work was to identify whether MP can affect myelin impairment accompanying intracellular oedema induced by water intoxication. METHODS For induction o...
متن کاملEstimated Specific Gravity with Quantitative CT Scan in Traumatic Brain Injury
An uncontrolled increase in intracranial pressure (ICP), often due to cerebral oedema, is the most common cause of death in traumatic brain injury (TBI) patients. Different types of oedema coexist in TBI patients: vasogenic oedema and cytotoxic oedema. Vasogenic oedema occurs with the extravasation of fluid into the extracellular space following blood brain barrier (BBB) disruption. Cytotoxic o...
متن کاملMicrocystic macular oedema in multiple sclerosis is associated with disease severity.
Macular oedema typically results from blood-retinal barrier disruption. It has recently been reported that patients with multiple sclerosis treated with FTY-720 (fingolimod) may exhibit macular oedema. Multiple sclerosis is not otherwise thought to be associated with macular oedema except in the context of comorbid clinical uveitis. Despite a lack of myelin, the retina is a site of inflammation...
متن کاملPathology and Electron Microscopy of Malaria
Brain : Many, but not all, post mortem brain in cases of fatal malaria has been described as oedematous (Riganti et al., 1990). Cerebral oedema is detected less commonly during life, in two of ten unusually severe cases of cerebral malaria in Thailand, cerebral oedema developed as an agonal phenomenon (Looareesuwan et al., 1983). Macpherson et al. (1985) found minimal evidence of oedema. Oo et ...
