The yield of infarcted hemispheres following unilateral carotid ligation in gerbils under ketamine anesthesia substantially exceeded that occurring under pentobarbital anesthesia. In addition to increasing the gerbil stroke model's efficiency, ketamine provided a shorter recovery period, thus allowing earlier observation of clinical signs of brain injury. These results support the contention th...

objective: following traumatic brain injury, disruption of blood-brain-barrier and consequent brain edema are critical events which might lead to increasing intracranial pressure (icp), and nerve damage. the current study assessed the effects of aqueous date fruit extract (adfe) on the aforementioned parameters. materials and methods: in this experimental study, diffused traumatic brain injury ...

OBJECTIVE Lactoferrin (Lf) is an iron-binding glycoprotein secreted in maternal milk presenting anti-inflammatory and antioxidant properties. It shows efficient absorption into the brain from nutritional source. Brain injury frequently resulting from cerebral hypoxia-ischemia (HI) has a high incidence in premature infants with ensuing neurodevelopmental disabilities. We investigated the neuropr...

Basic fibroblast growth factor (bFGF) and nerve growth factor (NGF) were administered into the rat brain following unilateral fimbria-fornix transection. Both bFGF and NGF stimulated the sprouting of acetylcholinesterase (AChE) positive fibers in the hippocampus on the lesioned side. Furthermore, a small number of AChE-positive fibers were regenerated even when only the vehicle was administered...

Asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. Although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but Lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. In this article, three cases of acu...

Brain edema (BE) research lacks quantitative regional methods. We modified the method of Pappius and McCann (1969), who used radioactive iodinated P serum albumin (R1SA) as a label for vasogenic BE fluid. To correct for intravascular plasma volume we used Cr^ labelled red blood cells and calculated equivalent extravascular plasma volume (EVPV). The modified RISA method was compared with a stand...

brain edema plays an important role in secondary tissue damage following traumatic brain injury (tbi) but the underlying mechanisms are not entirely elucidated. the g protein coupled receptor fm-4 and its ligands, neuromedin s (nms) and neuromedin u (nmu), are expressed in diverse brain areas, and have a variety of roles in nociception, inflammation, and stress but their probable changes after ...

traumatic brain injury resulting road accidents create damage to the brain. the severe brain injury may cause extensive tissue loss of several parenchyma which results in cavities due to primary destruction and secondary injuries such as ischemia and inflammation. recent findings suggest that neuronal precursors in the adult mammalian brain can be a therapeutic target in ischemic brain injuries...

objective: to determine the effects of pre-injury consumption of anti-platelet agents on the 30-day outcomes of patients with mild traumatic brain injury (tbi). methods: this prospective cohort study was conducted at three general hospitals in tehran, iran between july 2013 and july 2014. the study population included all patients with mild tbi aged over 18 years that medicated with aspirin or ...
