The regional distribution of albumin in serum extravasations of cerebral edema was visualized on intact brain slices by autoradiography of 125I-labeled antibodies directed against albumin. Following autoradiographic imaging of edema protein spread, concentrations of total serum proteins were

BACKGROUND It has been hypothesized that resuscitation with crystalloids after brain trauma increases brain edema compared with colloids, but previous studies on the subject have been inconclusive. To test this hypothesis, the authors compared groups resuscitated with either colloid or

To evaluate the effectiveness of steroids in the treatment of traumatic cerebral edema, we have hypothesized that the distribution of water and RISA is diminished by Dex and have experimentally tested this proposition with the rat model of cortical cold injury. Dex was found to have no effect on the

In the present study, the immunofluorescent and immunoperoxidase methods were applied to demonstrate the serum proteins in vasogenic brain edema (6). Using these techniques on paraffin embedded formalin fixed human brains with carcinoma metastases, albumin was identified specifically in the edema

Vascular endothelial growth factor (VEGF) is known to be an important stroke-related pathogenic factor for the formation of brain edema. We examined the therapeutic effect of human serum albumin on VEGF expression in acute ischemic stroke. Adult male Sprague-Dawley (SD) rats were subjected to Middle

Therapy for vasogenic brain oedema (VBE) is still an unsolved problem. Experimental work with the aim of establishing an oncotherapeutic option is presented. VBE is performed by focal freeze injury in rats. Using a stereotactic head holder hypo- or hyperosmolar human serum albumin is administered

OBJECTIVE Human albumin may be effective in the treatment of posttraumatic brain edema due to its hyperoncotic features. Therefore, the aim of the experimental study presented in this paper has two points: the first is to evaluate the efficacy of intraventricular hyperoncotic human albumin on

The Effects of Stereotactic Cerebroventricular Administration of Albumin, Mannitol, Hypertonic Sodium Chloride, Glycerin and Dextran in Rats with Experimental Brain Edema.

OBJECTIVE To evaluate the effects of cerebroventricular administration of hyperoncotic/hyperosmotic agents on edematous brain tissue in rats with experimental head trauma. METHODS The study included 54 female Sprague-Dawley rats with weights ranging between 200 and 250 g. Six experimental groups

The present study examined whether hemodilution with 20% human serum albumin (HSA) or 10% hydroxyethyl starch (HES) improved the outcome from closed-head trauma (CHT) in rats. Rats anesthetized with halothane were given one of three hemodilution solutions (i.e., 20% HSA, 10% HES, or control [0.9%

The effects of dexamethasone (Dex) on the blood-brain distribution of 14C-alpha-aminoisobutyric acid (AIB) and 125I-albumin (RISA) was studied in the rat freeze-lesion model of cerebral edema. Untreated and Dex-treated rats were studied by intravenously administering either AIB or RISA immediately

Brain edema (BE) research lacks quantitative regional methods. We modified the method of Pappius and McCann (1969), who used radioactive iodinated I125 serum albumin (RISA) as a label for vasogenic BE fluid. To correct for intravascular plasma volume we used Cr51 labelled red blood cells and

To explore whether human albumin (Alb) administration prior to thrombolysis with recombinant tissue plasminogen activator (rt-PA) can eliminate brain damage induced by this treatment given after the effective and safe window of 3h after stroke onset. Rats were subjected to embolic stroke by

Changes in brain water, sodium, potassium, and albumin contents and blood-brain barrier (BBB) permeability were determined between 1 hr and 42 days following occlusion of the middle cerebral artery in rats. Brain oedema was maximal 24 hrs, remained high for 3 days, and was resolved by 4 weeks. These

The authors examined the effect of delayed high-concentration albumin therapy on ischemic injury in a highly reproducible model of middle cerebral artery (MCA) occlusion in rats. Male Sprague-Dawley rats weighing 270 to 320 g were anesthetized with halothane and subjected to 120 minutes of temporary
