Brain Edema: Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)Edema: Abnormal fluid accumulation in TISSUES or body cavities. Most cases of edema are present under the SKIN in SUBCUTANEOUS TISSUE.Aquaporin 4: Aquaporin 4 is the major water-selective channel in the CENTRAL NERVOUS SYSTEM of mammals.Blood-Brain Barrier: Specialized non-fenestrated tightly-joined ENDOTHELIAL CELLS with TIGHT JUNCTIONS that form a transport barrier for certain substances between the cerebral capillaries and the BRAIN tissue.Brain Injuries: Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.Pulmonary Edema: Excessive accumulation of extravascular fluid in the lung, an indication of a serious underlying disease or disorder. Pulmonary edema prevents efficient PULMONARY GAS EXCHANGE in the PULMONARY ALVEOLI, and can be life-threatening.Body Water: Fluids composed mainly of water found within the body.Brain Chemistry: Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.Specific Gravity: The ratio of the density of a material to the density of some standard material, such as water or air, at a specified temperature.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Brain Neoplasms: Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum.

Clinical signs include impaired cognition; APHASIA; AGRAPHIA; weak and numbness in the face and arms, contralaterally or bilaterally depending on the infarction.Cerebrovascular Circulation: The circulation of blood through the BLOOD VESSELS of the BRAIN.Cerebral Hemorrhage: Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.Brain Infarction: Tissue NECROSIS in any area of the brain, including the CEREBRAL HEMISPHERES, the CEREBELLUM, and the BRAIN STEM. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis.Gerbillinae: A subfamily of the Muridae consisting of several genera including Gerbillus, Rhombomys, Tatera, Meriones, and Psammomys.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images.

Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.Neuroprotective Agents: Drugs intended to prevent damage to the brain or spinal cord from ischemia, stroke, convulsions, or trauma. Some must be administered before the event, but others may be effective for some time after. They act by a variety of mechanisms, but often directly or indirectly minimize the damage produced by endogenous excitatory amino acids.Intracranial Hypertension: Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.Cerebral Cortex: The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulchi. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.Liver Failure, Acute: A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE.

Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).Diuretics, Osmotic: Compounds that increase urine volume by increasing the amount of osmotically active solute in the urine. Osmotic diuretics also increase the osmolarity of plasma.Meningioma: A relatively common neoplasm of the CENTRAL NERVOUS SYSTEM that arises from arachnoidal cells. The majority are well differentiated vascular tumors which grow slowly and have a low potential to be invasive, although malignant subtypes occur. Meningiomas have a predilection to arise from the parasagittal region, cerebral convexity, sphenoidal ridge, olfactory groove, and SPINAL CANAL. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2056-7)Water: A clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)Water Intoxication: A condition resulting from the excessive retention of water with sodium depletion.Hepatic Encephalopathy: A syndrome characterized by central nervous system dysfunction in association with LIVER FAILURE, including portal-systemic shunts. Clinical features include lethargy and CONFUSION (frequently progressing to COMA); ASTERIXIS; NYSTAGMUS, PATHOLOGIC; brisk oculovestibular reflexes; decorticate and decerebrate posturing; MUSCLE SPASTICITY; and bilateral extensor plantar reflexes (see REFLEX, BABINSKI). ELECTROENCEPHALOGRAPHY may demonstrate triphasic waves. (From Adams et al., Principles of Neurology, 6th ed, pp1117-20; Plum & Posner, Diagnosis of Stupor and Coma, 3rd ed, p222-5)Time Factors: Elements of limited time intervals, contributing to particular results or situations.Aquaporins: A class of porins that allow the passage of WATER and other small molecules across CELL MEMBRANES.Astrocytes: A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the BLOOD-BRAIN BARRIER. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with MICROGLIA) respond to injury.Hyperammonemia: Elevated level of AMMONIA in the blood. It is a sign of defective CATABOLISM of AMINO ACIDS or ammonia to UREA.Rats, Wistar: A strain of albino rat developed at the Wistar Institute that has spread widely at other institutions. This has markedly diluted the original strain.Ischemic Attack, Transient: Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)Edema Disease of Swine: An acute disease of young pigs that is usually associated with weaning. It is characterized clinically by paresis and subcutaneous edema.Brain Stem: The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.Meningeal Neoplasms: Benign and malignant neoplastic processes that arise from or secondarily involve the meningeal coverings of the brain and spinal cord.Claudin-5: A claudin subtype that is found localized to TIGHT JUNCTIONS in VASCULAR ENDOTHELIAL CELLS. The protein was initially identified as one of several proteins which are deleted in VELOCARDIOFACIAL SYNDROME and may play an important role in maintaining the integrity of the BLOOD-BRAIN BARRIER.Rats, Inbred Strains: Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding.Cerebral Arteries: The arterial blood vessels supplying the CEREBRUM.Neurons: The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.Intracranial Embolism and Thrombosis: Embolism or thrombosis involving blood vessels which supply intracranial structures. Emboli may originate from extracranial or intracranial sources. Thrombosis may occur in arterial or venous structures.PolyvinylsReperfusion: Restoration of blood supply to tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. It is primarily a procedure for treating infarction or other ischemia, by enabling viable ischemic tissue to recover, thus limiting further necrosis. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing REPERFUSION INJURY.Cerebral Veins: Veins draining the cerebrum.Collagenases: Enzymes that catalyze the degradation of collagen by acting on the peptide bonds.Brain Abscess: A circumscribed collection of purulent exudate in the brain, due to bacterial and other infections. The majority are caused by spread of infected material from a focus of suppuration elsewhere in the body, notably the PARANASAL SINUSES, middle ear (see EAR, MIDDLE); HEART (see also ENDOCARDITIS, BACTERIAL), and LUNG. Penetrating CRANIOCEREBRAL TRAUMA and NEUROSURGICAL PROCEDURES may also be associated with this condition. Clinical manifestations include HEADACHE; SEIZURES; focal neurologic deficits; and alterations of consciousness. (Adams et al., Principles of Neurology, 6th ed, pp712-6)Cranial Sinuses: Large endothelium-lined venous channels situated between the two layers of DURA MATER, the endosteal and the meningeal layers. They are devoid of valves and are parts of the venous system of dura mater. Major cranial sinuses include a postero-superior group (such as superior sagittal, inferior sagittal, straight, transverse, and occipital) and an antero-inferior group (such as cavernous, petrosal, and basilar plexus).Laryngeal Edema: Abnormal accumulation of fluid in tissues of any part of the LARYNX, commonly associated with laryngeal injuries and allergic reactions.Mice, Inbred C57BLTomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Hypothermia, Induced: Abnormally low BODY TEMPERATURE that is intentionally induced in warm-blooded animals by artificial means. In humans, mild or moderate hypothermia has been used to reduce tissue damages, particularly after cardiac or spinal cord injuries and during subsequent surgeries.Antipyrine: An analgesic and antipyretic that has been given by mouth and as ear drops. Antipyrine is often used in testing the effects of other drugs or diseases on drug-metabolizing enzymes in the liver. (From Martindale, The Extra Pharmacopoeia, 30th ed, p29)Neurologic Examination: Assessment of sensory and motor responses and reflexes that is used to determine impairment of the nervous system.Mannitol: A diuretic and renal diagnostic aid related to sorbitol. It has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity.Neurosurgical Procedures: Surgery performed on the nervous system or its parts.Injections, Intraperitoneal: Forceful administration into the peritoneal cavity of liquid medication, nutrient, or other fluid through a hollow needle piercing the abdominal wall.Nimodipine: A calcium channel blockader with preferential cerebrovascular activity.

Transforming growth factor-alpha acting at the epidermal growth factor receptor reduces infarct volume after permanent middle cerebral artery occlusion in rats. (1/1215)

Transforming growth factor-alpha (TGF-alpha) is a ligand for the epidermal growth factor (EGF) receptor (EGFR), and is more abundant than EGF in the brain. The authors studied whether administration of exogenous TGF-alpha into the brain can protect neurons against ischemia in a model of permanent middle cerebral artery (MCA) occlusion in the rat, and whether any effect of TGF-alpha was mediated by EGFR by administering 4,5-dianilinophthalimide (DAPH), a protein-tyrosine kinase inhibitor with high selectivity for EGFR. Rats received either TGF-alpha (10 or 25 ng), DAPH (100 ng), DAPH plus TGF-alpha (25 ng), or vehicle in the ipsilateral first ventricle. Drugs were administered twice: 30 minutes before and 30 minutes after MCA occlusion, and infarct volume was evaluated 24 hours later. Transforming growth factor-alpha at the dose of 25 ng caused a statistically significant reduction of infarct volume (60%) in relation to ischemic rats administered vehicle. This reduction was no longer seen when TGF-alpha was administered in combination with DAPH. The present results show that TGF-alpha can protect neurons from ischemic damage, and that this effect is mediated by EGFR. It is suggested that activation of EGFR-mediated intracellular signalling pathways contributes to the survival of neural cells susceptible to ischemic injury.  (+info)

Computerised axial tomography in patients with severe migraine: a preliminary report. (2/1215)

Patients suffering from severe migraine, usually for many years, have been examined by the EMI scanner between attacks. Judged by criteria validated originally by comparison with pneumoencephalography, about half of the patients showed evidence of cerebral atrophy. Perhaps of more significance than generalised atrophy was the frequency of areas of focal atrophy and of evidence of infarction.  (+info)

Two similar cases of encephalopathy, possibly a reversible posterior leukoencephalopathy syndrome: serial findings of magnetic resonance imaging, SPECT and angiography. (3/1215)

Two young women who had encephalopathy that resembled reversible posterior leukoencephalopathy syndrome are presented. The brain magnetic resonance imaging (MRI) of these patients exhibited similar T2-high signal lesions, mostly in the white matter of the posterior hemispheres. Xe-SPECT during the patients' symptomatic period showed hypoperfusion in the corresponding areas, and angiography demonstrated irregular narrowing of the posterior cerebral artery. Clinical manifestations subsided soon after treatment, and the abnormal radiological findings also were almost completely resolved. Thus, we concluded that transient hypoperfusion followed by ischemia and cytotoxic edema might have had a pivotal role in these cases.  (+info)

Significance of acute cerebral swelling in patients with sylvian hematoma due to ruptured middle cerebral artery aneurysm, and its management. (4/1215)

A retrospective study of 75 patients treated surgically for ruptured middle cerebral artery (MCA) aneurysm within 48 hours evaluated clinical grade at admission, secondary development and management of cerebral swelling associated with space-occupying hematoma, cerebral infarction caused by vasospasm, development of hydrocephalus, and clinical outcome. Clinical grade at admission was significantly better in patients without than in those with hematoma (p < 0.01). Twenty-seven patients with sylvian hematoma caused by ruptured MCA aneurysm often developed ipsilateral cerebral swelling in the early period after subarachnoid hemorrhage. Seventeen of these patients developed serious cerebral swelling and received barbiturate therapy. Nine of these 17 patients had good outcome, but six patients died of cerebral swelling. The incidence of hydrocephalus was significantly higher in patients with than in those without hematoma (p < 0.01). The incidence of infarction was more pronounced in patients with sylvian hematoma. Clinical outcome was significantly better in patients without than in those with sylvian hematoma (p < 0.01). Development of cerebral swelling in patients with sylvian hematoma due to ruptured MCA aneurysm has a significant effect on outcome, and improvements in management are required.  (+info)

Cerebral blood flow in the monkey after focal cryogenic injury. (5/1215)

A focal cryogenic lesion was made in the left superior frontal gyrus of the anesthetized macaque brain. Cerebral blood flow (CBF) was determined by the hydrogen clearance technique before and during the 4 hours following trauma. Local CBF in tissue adjacent to the lesion increased in the first half hour after the lesion was made and then decreased during the ensuing 3 1/2 hours. Local CBF in the contralateral superior frontal gyrus, as well as total CBF and oxygen consumption, were unchanged by cryogenic trauma. The spread of vasogenic edema into uninjured tissue probably accounts for the observed decrease in local CBF. This experimental model may assist in discovering therapy to alter favorably the spatial and temporal profile of pathologic CBF changes in tissue surrounding an acute lesion of the brain.  (+info)

Abrupt exacerbation of acute subdural hematoma mimicking benign acute epidural hematoma on computed tomography--case report. (6/1215)

A 75-year-old male was hit by a car, when riding a bicycle. The diagnosis of acute epidural hematoma was made based on computed tomography (CT) findings of lentiform hematoma in the left temporal region. On admission he had only moderate occipitalgia and amnesia of the accident, so conservative therapy was administered. Thirty-three hours later, he suddenly developed severe headache, vomiting, and anisocoria just after a positional change. CT revealed typical acute subdural hematoma (ASDH), which was confirmed by emergent decompressive craniectomy. He was vegetative postoperatively and died of pneumonia one month later. Emergent surgical exploration is recommended for this type of ASDH even if the symptoms are mild due to aged atrophic brain.  (+info)

Epilepsy after two different neurosurgical approaches to the treatment of ruptured intracranial aneurysm. (7/1215)

One-hundred-and-fifty-two patients who underwent surgery for intracranial aneurysm were studied to determine the incidence of postoperative epilepsy in relation to the site of the aneurysm and the type of surgical approach. The overall incidence of epilepsy was 22%. Of the 116 patients treated by the intracranial approach 27.5% developed epilepsy, in contrast with only 5% of the 36 patients who had carotid artery ligation in the neck. Epilepsy occurred most frequently (35%) with middle cerebral artery aneurysms, especially if moderate or severe operative trauma was sustained and there was postoperative dysphasia.  (+info)

Glial and capillary density of the pontine white matter in swelling and atrophy. (8/1215)

A total of 48 autopsied brains were morphometrically examined for the relation between pontine geometry and structural parameters. In each case, the numerical density of neuroglial cells Nv(G) and the linear density of capillary network Lv(C) of the pontine white matter were determined stereologically from the counts of glial nuclear profiles and capillary transections per constant area of a histological section with a constant thickness. It was revealed that in general the glial numerical density increased with advancing atrophy and decreased with increasing swelling, whereas the capillary linear density remained fairly constant especially in the advanced stage of brain swelling. Further analysis of this relation using a model of pontine geometry has made it clear that the total capillary length in the swollen white matter increases probably at the expense of the capillary caliber as swelling advances. The changes in the ratio Lv(C)/Nv(G) under pathological conditions are emphasized and possible utility of classifying stages of acute brain swelling from a viewpoint of microvascular dimension is suggested.  (+info)

Aquaporin 4 (AQP4), the most abundant water channel protein in the brain, is involved in brain edema induced by ischemic insults. To evaluate whether the neuroprotective effects of estrogen are associated with AQP4 expression and edema formation, changes in AQP levels and ischemic edema were examined in the brains of male and female mice subjected to transient middle cerebral artery occlusion. Infarct volume and edema formation were markedly less in females than in males. AQP4 expression in the ischemic cortex of females was relatively well preserved, whereas it was significantly decreased in males. These effects disappeared in ovariectomized females but were reversed by estrogen replacement. Furthermore, AQP4 expression was decreased with increased brain edema in females treated with ICI182,780, an estrogen receptor antagonist. These findings suggest that the estrogen effect on the reduction of ischemic brain edema is associated with the preserved level of AQP4 that is partly mediated by ...
Bradykinin as the major product of the contact-kinin system triggers inflammation and brain edema formation (for a comprehensive overview, see [2]). In this study, we aimed at targeting FXIIa, the very first step required for activation of this pathway in the plasma to alleviate pathological events leading to secondary injury after brain trauma.. Following brain trauma, bradykinin levels in the cerebrospinal fluid of patients are markedly elevated up to 48 h and decrease thereafter, reaching levels of the control group within 72 h after injury [19]. Similar to the human situation, bradykinin levels maximally increase within 2 h in the brain tissue of mice after experimentally induced focal brain trauma and then subsequently decline [7]. In accordance, we observed that plasma bradykinin levels increased twofold to threefold within 2 h after focal cortical injury in mice. As FXIIa activates plasma kallikrein, it is plausible to assume that posttraumatic bradykinin release is dependent on the ...
Introduction: Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage.

To evaluate the location and early time course for development of cerebral edema following therapy for diabetes, streptozotocin-diabetic rats were subjected to constant i.v. infusion with saline and regular insulin. At the end of 1, 2, and 5 h of therapy, these rats were killed and tested for density of the cerebral cortex, subcortical white matter, caudate-putamen, thalamus, and medulla. Density data from treated animals were compared with those from control animals. From these data, change in brain tissue volume as water was calculated.. Diabetic animals killed after 1 h of fluid and insulin therapy demonstrated a modest increase in brain water content of all areas tested except white matter. Following 2 h of therapy, all regions tested were edematous, with a magnitude of edema that was similar to that seen at 1 h. After 5 h of therapy, there was further increase in water content of the cerebral cortex, but not the other regions examined. Treatment with saline alone did not result in central ...
Aquaporins are a family of water channel proteins that provide a major pathway for osmotically driven water transport through cell membranes. So far, 13 aquaporin isoforms (AQP0-AQP12) have been identified in mammalian species (Verkman, 2005). AQP4, the predominant isoform in adult brain, is primarily expressed at the border between brain parenchyma and major fluid compartments, including astrocyte foot processes and glia limitans, as well as ependymal cells and subependymal astrocytes (Venero et al., 2001). The bidirectional water channel AQP4 has an important role in water homeostasis in the brain. It probably helps in the redistribution and absorption of edema fluid, because disruption of AQP4 is found to contribute to the pathophysiology of brain edema (Zador et al., 2007). AQP4 knockout markedly reduced brain swelling in mouse models of cytotoxic brain edema, whereas it significantly worsened outcome in mouse models of vasogenic brain edema (Papadopoulos and Verkman, 2007). Thus, AQP4 ...
In the present study, we evaluated early brain injury: BBB disruption, brain edema, brain tissue death, as well as mortality and neurological deficits. Cell death, especially apoptosis, occurred in neuronal tissues, particularly in the hippocampus and basal cortex adjacent to the blood deposits. Neuronal cell death contributes to cytotoxic edema, which usually develops early after brain injury.20 In the meantime, BBB permeability was enhanced as shown by extravasations of Evans blue dye, probably because of endothelial apoptosis. BBB breakdown leads to vasogenic brain edema after SAH.4 z-VAD-FMK abolished caspase-3 and TUNEL staining in cerebral endothelial cells and reduced IgG leaking after SAH. Apoptotic death of cerebral endothelial cells might have important impact on neurological functions because z-VAD-FMK improved neurological outcome at 24 hours.. After initial bleeding, apoptosis of brain tissues may be caused by elevated intracranial pressure (ICP), toxicity of blood components,5 ...
We develop novel neuroimaging tools to better quantify brain edema and blood-brain barrier integrity in the setting of cerebral ischemia. By creating high specificity methods using non-invasive imaging, we have advanced our understanding of the role brain edema plays in modulating neurological recovery after stroke. These studies have revealed that brain edema may impact recovery in up to 25% of all stroke patients. Our imaging tools not only provide insight into the pathophysiology of secondary brain injury, but can also serve as intermediate endpoints in clinical trials as part of proof of concept studies for anti-edema treatments.. ...
Treatments to improve the neurological outcome of edema and cerebral ischemic stroke are severely limited. Here, we present the first in vivo single cell images of cortical mouse astrocytes documenting the impact of single vessel photothrombosis on cytotoxic edema and cerebral infarcts. The volume of astrocytes expressing green fluorescent protein (GFP) increased by over 600% within 3 hours of ischemia. The subsequent growth of cerebral infarcts was easily followed as the loss of GFP fluorescence as astrocytes lysed. Cytotoxic edema and the magnitude of ischemic lesions were significantly reduced by treatment with the purinergic ligand 2-methylthioladenosine 5′ diphosphate (2-MeSADP), an agonist with high specificity for the purinergic receptor type 1 isoform (P2Y1R). At 24 hours, cytotoxic edema in astrocytes was still apparent at the penumbra and preceded the cell lysis that defined the infarct. Delayed 2MeSADP treatment, 24 hours after the initial thrombosis, also significantly reduced cytotoxic

In the present study we first elucidated the NTN‐1-mediated signaling pathway in BBB protection following SAH in rats. Our results showed that endogenous NTN‐1 and DCC receptor were upregulated in the early stage after SAH. Exogenous NTN‐1 treatment reduced brain edema and BBB permeability and thereby alleviated neurological deficits after SAH, which were accompanied by an increase in FAK phosphorylation and a decrease in RhoA activity as well as endothelial junction protein upregulation. In contrast, silencing of endogenous NTN‐1 by special siRNA exacerbated brain edema, BBB disruption, and neurological deficits. Furthermore, knockdown DCC using DCC siRNA or inhibition of FAK by Fib‐14 abolished the neuroprotective effects of exogenous NTN‐1 on BBB integrity and brain edema formation, which were associated with the increased RhoA activity and MMP‐9 and the degraded endothelial junction proteins and basal lamina at 24 hours after SAH. Taken together, these findings support our ...

... (AQP4) inhibitor 2-(nicotinamide)-1,3,4-thiadiazole, TGN-020, inside a mouse style of focal cerebral ischemia using 7. research convincingly exhibited that pretreatment using the AQP4 inhibitor TGN-020 considerably reduced the quantity of mind edema connected with ischemic damage. Ischemic edema is usually thought to be initiated by influx of Na+ connected with energy failing. Higher osmolarity circumstances create the generating force for drinking water influx into cells, leading to ionic edema [17]. This early edema stage, so-called cytotoxic edema, is certainly thought to last a long time before mass leakage of drinking water into the human brain ensues, making so-called vasogenic edema [18]. AQP4 is certainly thought to play a substantial function in the real drinking water flux in both procedures. Flux through AQP4 is certainly buy 154992-24-2 bidirectional and solely reliant on osmolarity distinctions between your two spaces ...

OBJECTIVES: A novel method of long-term telemetric monitoring of mean arterial pressure (MAP) and intracranial pressure (ICP) for the determination of current cerebral perfusion pressure (CPP) and the time course of ICP in freely moving rats under physiological conditions and with increased ICP due to the induced cerebral edema were studied. METHODS: The brain edema, that caused volume enlargement and ICP elevation was achieved in entirely experimental conditions without any parallel pathological process. Vasogenic/extracellular edema was induced by osmotic blood-brain barrier disruption (BBBd) and for induction of cytotoxic/intracellular edema the water intoxication model (WI) was used. RESULTS: The results showed significantly elevated values of ICP both in conditions of osmotic blood-brain barrier disruption (BBBd model) and cytotoxic/intracellular edema (WI model) compared to intact rats. The average values of ICP were significantly higher in WI model compared to osmotic BBBd model. Distinct ...

Neuromyelitis optica (NMO) is an autoimmune disorder of the central nervous system, which is characterized by autoantibodies directed against the water channel aquaporin-4 (AQP4). As one of the main water regulators in the central nervous system, APQ4 is supposed to be involved in the dynamics of brain edema. Cerebral edema seriously affects clinical outcome after ischemic stroke; we therefore aimed to investigate whether NMO-antibodies may exert the same functional effects as an AQP4-inhibitor in-vivo in acute ischemic stroke. Sixteen male Wistar rats were randomized into two groups twice receiving either purified NMO-IgG or immune globulin from healthy controls, 24 hours and 30 minutes before middle cerebral artery occlusion (MCAO) was performed. T2-weighted MRI was carried out 24 hours after MCAO. MRI-examination showed a significant increase of infarct size in relation to the cerebral hemisphere volume with NMO-IgG treated animals (27.1% ± 11.1% vs. 14.3% ± 7.2%; p < 0.05) when corrected for the
Our results identify a water channel protein as the first defined autoantigen pertinent to an inflammatory demyelinating disorder of the human CNS. AQP4 is an integral protein of astrocytic plasma membranes (15-18), and is highly concentrated in foot process domains facing microvessels where it interacts with dystrophin-associated proteins (10, 17). The AQP4 channel is mercurial-insensitive, and is the predominant water channel in the CNS. It has a pathophysiologic role in brain edema formation following water intoxication (14, 19, 20) or focal cerebral ischemia (21). Brain edema occurring in oncologic contexts is attributed to the up-regulation of AQP4 in high-grade astrocytomas and in reactive astrocytes related to cerebral adenocarcinoma metastases (21, 22).. The present study is the first to implicate AQP4 in the pathogenesis of any autoimmune disorder. NMO may represent the first example of a novel class of autoimmune channelopathies. Unlike MS, the cerebrospinal fluid in patients who have ...

Cerebral oedema (CO) is the most dreaded complication of diabetic ketoacidosis (DKA) in children. Despite advances in many areas of the management of DKA, the mortality from CO has remained fairly constant for the past six decades.1-4 Mortality estimates vary widely, but some authors suggest this disorder is lethal in about 20% to 50% of victims.5,6 Fortunately, it is a rare occurrence, complicating about 1% of cases of DKA in children.5 Since it was first described in 1936, much effort has gone into the search for a cause for this condition.7 Despite these attempts, CO in childhood DKA remains a mysterious illness. It is unpredictable, sporadic, and deadly.. Researchers have suggested that the treatment for DKA may be causally related to the development of CO.3,4,8-12 The theory suggests that overzealous insulin use or hydration with excess free water administration to children with DKA cause a dramatic dysequilibrium between the osmolality of the serum and that of the brain. A fluid shift ...

blood-brain barrier (BBB). In the normal cerebral vasculature, endothelial tight junctions associated with astrocytes create an impermeable barrier (the BBB), through which access into the brain interstitium is dependent upon specific transport mechanisms. The BBB may be compromised in ischemia, trauma, infection, and metabolic derangements. Typically, vasogenic edema develops rapidly following injury. Cytotoxic edema refers to cellular swelling and occurs in a variety of settings, including brain ischemia and trauma. Early astrocytic swelling is a hallmark of ischemia. Brain edema that is clinically significant usually represents a combination of vasogenic and cellular components. Edema can lead to increased ICP as well as tissue shifts and brain displacement from focal processes (Chap. 274). These tissue shifts can cause injury by mechanical distention and compression in addition to the ischemia of impaired perfusion consequent to the elevated ICP. ...

I know it sounds obvious. But in cerbral oedema lets say due to vasgenic cause,the problem is cerebral vessels becoming more permeable and leaking out blood to extravascular compartment. Now how does the brain get bigger due to this. I mean for brain to get bigger, the intracellular fluid volume of brain cells must increase. So when these capillaries leak blood out, do near by brain cells absorb these water, increasing their intracellular volume and as a result we get enlarged brain? or does this leaked out fluid get stuck in brain interstitium making it bigger. I hope u understand my confusion, because leaking out fluid must make brain smaller otherwise. Thanks ...

An independent safety monitoring committee has found that patients with AD given the highest dose of an experimental monoclonal antibody, bapineuzumab, were more likely to develop cerebral vasogenic edema; the highest dose was subsequently discontinued from the clinical trial (Salloway et al., 2009). The Food and Drug Administration has also posted concerns regarding the safety of immunotherapy approaches, stating that microhemorrhage susceptibility is a risk factor for vasogenic edema. This highlights the importance of such safety assessments while developing immunotherapy strategies for the treatment of AD.. Although the diagnosis of microhemorrhages in human brain by gradient-echo sequence or T2*-weighted MRI (Offenbacher et al., 1996; Fazekas et al., 1999; Greenberg et al., 2004) has been established, the preclinical identification of cerebral microhemorrhage is challenging because microhemorrhage in a mouse brain is approximately two orders of magnitude smaller (in the range 20 to 400 μm) ...

Aquaporin-4 (AQP4) is the major water channel in the central nervous system and plays an important role in the brains water balance, including edema formation and clearance. There are 6 splice variants; the shorter ones assemble into functional, tetrameric square arrays; the longer is palmitoylated on N-terminal cysteyl residues) (Suzuki et al., 2008). The longest, Aqp4e, has a novel N-terminal domain and forms a water channel in the plasma membrane although various shorter variants dont (Moe et al., 2008). AQP4, like AQP0 (1.A.8.8.2), forms water channels but also forms adhesive junctions (Engel et al., 2008) (causes cytotoxic brain swelling in mice (Yang et al., 2008)) Mice lacking Aqp4 have impaired olfactions (Lu et al., 2008). Aqp4 is down regulated in skeletal muscle in muscular dystrophy (Au et al. 2008). The crystal structure is known to 2.8 Å resolution (Tani et al., 2009). The structure reveals 8 water molecules in each of the four channels, supporting a hydrogen-bond isolation ...

Background: Pioneer studies demonstrate the impact of extreme sport load on the human brain, leading to threatening conditions for athletes health such as cerebral edema. The investigation of brain water diffusivity, allowing the measurement of the intercellular water and the assessment of cerebral edema, can give a great contribution to the investigation of the effects of extreme sports on the brain. We therefore assessed the effect of supra-physiological effort (extreme distance and elevation changes) in mountain ultra-marathons (MUMs) athletes combining for the first time brain magnetic resonance imaging (MRI) and blood parameters.. Methods:This longitudinal study included 19 volunteers (44.2 ± 9.5 years) finishing a MUM (330 km, elevation + 24000 m). Quantitative measurements of brain diffusion-weighted images (DWI) were performed at 3 time-points: Before the race, upon arrival and after 48 h. Multiple blood biomarkers were simultaneously investigated. Data analyses included brain apparent ...

In March, Juno Therapeutics (NASDAQ:JUNO) announced that it was ending development of JCAR015 after five patients with acute lymphoblastic leukemia (ALL) died from cerebral edema -- brain swelling -- in its phase 2 clinical trial. The lethal side effect made it unlikely the treatment could get approved, despite extremely strong efficacy data.. After a review of the data, the company said it thought there were protocol modifications and process improvements that would hopefully make JCAR015 safer, but those changes would require Juno to go back to phase 1. Since the biotech has other drug candidates to treat ALL, Juno made a decision with its partner Celgene (NASDAQ:CELG) that it would be best to shelve JCAR015 and focus on the other ALL therapies.. All told, the biotech spent $46.4 million on the failed drug, which could end up being a little higher depending on wrap-up costs. ...

The aim of this work was to study the vascular endothelial growth factor A (VEGF-A) pathway and peritumoral brain edema (PTBE) through comparison of non-angiomatous and angiomatous meningiomas. Meningiomas are common intracranial tumors, which often have PTBE. VEGF-A is an integral part of PTBE formation and angiogenesis, and the capillary-rich angiomatous meningiomas are known for their PTBE. The VEGF-A receptor VEGFR-2 is responsible for the angiogenic effect of VEGF-A on endothelial cells, which is enhanced by the co-receptor neuropilin-1. Forty non-angiomatous, 22 angiomatous meningiomas, and 10 control tissue samples were collected for the study. Magnetic resonance images were available for 40 non-angiomatous and 10 angiomatous meningiomas. Tissue sections were immunostained for CD34, MIB-1, estrogen- and progesterone receptors. ELISA, chemiluminescence, and RT-qPCR were used for VEGF-A, VEGFR-2, and neuropilin-1 protein and mRNA quantification. Angiomatous meningiomas had larger PTBE (695 ...
The pathogenesis of hepatic encephalopathy (HE) is multifactorial and often associated with the development of brain oedema.

Cerebral edema is seen heterogenous group of neurological disease states that mainly fall under the categories of metabolic, infectious, neoplasia, cerebrovascular, and traumatic brain injury disease states. Regardless of the driving force, cerebral edema is defined as the accumulation of fluid in the brains intracellular and extracellular spaces. This occurs secondary to alterations in the complex interplay between four distinct fluid compartments within the cranium. In any human cranium; fluid is contained in the blood, the cerebrospinal fluid, interstitial fluid of the brain parenchyma, and the intracellular fluid of the neurons and glia. Fluid movement occurs normally between these compartments and depends on specific concentrations of solutes (such as sodium) and water. In brain-injured states, the normal regulation of this process is disturbed and cerebral edema can develop. Cerebral edema leads to increased intracranial pressure and mortality secondary to brain tissue compression, given ...

October 21, 2013 - Regeneron Pharmaceuticals, Inc. (Tarrytown, NY) announced positive top-line results for Eylea (aflibercept) from the phase 3 VIBRANT trial in treating macular edema following branch retinal vein occlusion (BRVO). VIBRANT was a double-masked, randomized, active-controlled study of 183 patients with macular edema following BRVO. In the trial, 53% of patients who received aflibercept 2 mg every 4 weeks gained at least 15 letters in vision from baseline at week 24, the primary endpoint of the study. This compares with 27% of patients in the laser group (P , .001) who had the same gain.. In addition, patients who received aflibercept 2 mg every 4 weeks achieved a 17.0-letter mean improvement over baseline in best-corrected visual acuity (BCVA) compared with a 6.9-letter mean improvement in patients who received laser (P , .0001), a key secondary endpoint.. The incidence of serious adverse events (SAE) was 9.9% in the aflibercept group and 9.8% in the laser group. One death and 1 ...
The underlying main issue in high altitude as mentioned before is due to the lack of oxygen in the air, a condition known as hypoxia. It is well known that hypoxia will lead to an elevated brain volume and this brain volume is due to an increase at least in part by swelling of the brain as a result of water retention, a term called brain edema. Brain edema may occur as a result of brain cells damage or death due to lack of oxygen and also may be related to the vascular supply to the brain which again is related to a lack of oxygen at a high altitude. The brain edema if not controlled will lead to the compression of the brain, raised/elevated intracranial pressure and lead to change in the mental status and further deterioration into coma and brain death.. With regards to high altitude pulmonary edema (HAPE), the underlying mechanism is due to exaggerated hypoxic pulmonary hypertension i.e. the arterial pressure of the lungs are increased dramatically as a result of the lack of oxygen and ...

Their findings offer hope for a treatment to more than 30,000 Americans who have Huntingtons symptoms and another 200,000 at risk of inheriting the disease. They also could help scientists better understand other fatal brain diseases such as amyotrophic lateral sclerosis and a certain type of dementia, as well as help researchers learn more about normal brain aging.. "We found these kind of traffic jams in cells, and if we can fix the traffic jams we can potentially provide a new avenue for treatment of neurodegenerative disease," said Jonathan Grima, a graduate student in the Johns Hopkins University School of Medicine department of neuroscience whose research was published this week in the journal Neuron.. Grima said its not clear if a drug developed to clear these jams could stop cells from dying, and thus stop progression of Huntingtons, but that is the goal. Grima works in the lab of Dr. Jeffrey Rothstein, director of Hopkins Brain Science Institute.. Rothstein, who normally focuses on ...
BACKGROUND: Significantly increased plasma and CSF IL-6 levels reflect underlying tissue damage following clinical and experimental traumatic brain injury (TBI). Catecholamines, used under clinical conditions to maintain adequate cerebral perfusion pressure, induce a sustained IL-6 release. Thus an additional elevation in IL-6 could aggravate brain edema in the acute posttraumatic phase. We studied the changes in plasma and cerebrospinal fluid (CSF) IL-6 levels 4 and 24 hours after experimental TBI and assessed possible time-dependent effects of norepinephrine infusion on IL-6 and brain edema. MATERIAL/METHODS: Paired plasma and CSF IL-6 measured at 4 and 24 hours following TBI (n=10) were compared to levels in non-traumatized rats (n=5). In a placebo-controlled trial, 20 brain-injured male Sprague-Dawley rats were randomized to receive norepinephrine or NaCl for 90 minutes at 4 or 24 hours after TBI. Plasma IL-6 was measured before, during, and after the infusion period. One hour after stopping ...
