the prevention of bbb breakdown and the subsequent vasogenic edema are important parts of the medical management of ischemic stroke. the purpose of this study was to investigate the ischemic tolerance effect of rosmarinus officinalis leaf hydro-alcoholic extract (rhe).five groups of animals were designed: sham (underwent surgery without mcao) and mcao groups, the mcao groups were pretreated ora...

conclusion the minimum concentration of triolein emulsion required to increase vascular permeability adequately with minimal brain edema in a cat model was 0.5%. results the lesion hemispheres showed mild hyperintensity due to edema on t2-weighted images, and contrast enhancement on post-contrast t1-weighted images in cats of group 1-5. cers showed statistically significant differences between ...

nimodipine (nm), as a lipophilic calcium channel blocker indicated for the prevention and treatment of neurological disorders, suffers from an extensive first pass metabolism, resulting in low oral bioavailability. polymeric micelles, self-assembled from amphiphilic polymers, have a core-shell structure which makes them unique nano-carriers with excellent performance as drug delivery. this inve...

this study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (bbb) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. methods: each age group of rats was sub div...

Introduction: Recent studies have reported that the Aloe vera (Aloe barbadensis miller) plant has anti-inflammatory and antioxidant effects. This study evaluated the neuroprotective effects of different doses of Aloe vera extract after traumatic brain injury (TBI) in male rats. Materials and Methods:  In this study, 70 male rats were divided into 2 groups; each group consists of 5 of sub-g...

abstract ischemic brain edema is one of the most important complications of a stroke. this study aims to investigate the impact of pre-feeding of flax seed oil on blood-brain barrier in rat stroke model. in this experimental study animals were randomly divided into 3 groups of experiment, sham, and control. each testing group itself was consisted of 3 subgroups receiving doses of flaxseed oil w...
