The Measurement of Cerebral Infarction Edema With Sodium 22 • Sodium 22 was used to determine quantitatively cerebral infarction edema in cats after occlusion of the middle cerebral artery. A comparison was made of the sodium 22 edema determination with the wet weight-dry weight method of edema determination. There was a high degree of correlation between the two methods. The sodium 22 method o...

The left cerebral hemisphere of Mongolian gerbils was used to elucidate the mechanisms of brain edema which develop during cerebral ischemia and after restoration of cerebral blood flow following temporary ischemia. Water content was measured by the tissue-drying method. Sodium and potssium ion concentration was measured by flame photometry. Passage of 131I-albumin (RISA) from blood to the cere...

BACKGROUND AND PURPOSE Stroke-prone spontaneously hypertensive rats (SHRSP) subjected to high sodium intake develop severe hypertension, cerebral edema, and proteinuria, culminating in organ damage and early death. MRI, which can be applied serially, provides the unique opportunity to study temporal and quantitative relations between these changes and whether diminution of sodium intake can att...

Cerebral edema develops in response to a variety of conditions, including traumatic brain injury and stroke, and contributes to the poor prognosis associated with these injuries. This study examines the use of optical coherence tomography (OCT) for detecting cerebral edema in vivo. Three-dimensional imaging of an in vivo water intoxication model in mice was performed using a spectral-domain OCT...

Cerebral edema is a well-known complication of malignant astrocytoma and metastatic brain tumour. Though far less frequent, the association of cerebral edema with meningioma is also recognized; this is unpredictable and sometimes out of proportion to tumour size. We describe three cases where the mass effect was due to severe edema, rather than the tumour itself and was responsible for a catast...

Background: Stroke is the third leading cause of invalidism and death in industrialized countries. There are conflicting reports about the effects of Angiotensin II on ischemia-reperfusion brain injuries and most data have come from chronic hypertensive rats. In this study, hypotensive and non-hypotensive doses of candesartan were used to investigate the effects of angiotensin II AT1 receptor b...

A BSTRACT Background Cerebral edema is an uncommon but devastating complication of diabetic ketoacidosis in children. Risk factors for this complication have not been clearly defined. Methods In this multicenter study, we identified 61 children who had been hospitalized for diabetic ketoacidosis within a 15-year period and in whom cerebral edema had developed. Two additional groups of children ...
