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...

background: nepeta dschuparensis bornm (np) is used as a medicinal herb in iran. in traditional medicine, this herb is extensively employed for curing ailments such as cardiovascular diseases. np has antioxidant and anti-inflammatory properties. this project examined the effects of the np extract on cyclooxygenase-2 (cox-2) and interleukin-1β (il-1β) protein levels and its efficacy in neuroprot...

Background: The death of neurons and cerebral edema are the main consequences of stroke. However, inflammatory processes play a key role in aggravating cerebral damage following stroke. The aim of this study was to investigate the effects of Viola odorant extract (VOE) on infarct volume (IV), neurologic deficits (ND), and expression of NF-κB and VCAM-1 in the MCAO model. Method: The animals we...

Objective(s) Opioid abuse is still remained a major mental health problem, a criminal legal issue and may cause ischemic brain changes including stroke and brain edema. In the present study, we investigated whether spontaneously withdrawal syndrome might affect stroke outcomes. Materials and Methods Addiction was induced by progressive incremental doses of morphine over 7 days. Behavioral si...

Topographical evaluation of aphasic brain lesions can enhance our knowledge of cognitive physiology and plasticity. This prospective study was conducted on 100 stroke-afflicted patients with aphasia admitted in Valie-Asr Hospital (Khorasan, Iran) in 2003. Topography of infarct lesions was detected by a neurologist based on the map of brain vascular territories in CT-scan. Aphasic lesions catego...

The intact omentum of 13 monkeys was lengthened, placed subcutaneously, and laid on the left cerebral hemisphere prior to occluding the left middle cerebral artery. Two of these 13 monkeys developed left cerebral infarct and a right hemiparesis. Nine other monkeys had their left middle cerebral artery occluded without omental protection. All of these 9 developed a left cerebral infarct and 8 of...

objectives in this study, we aimed to investigate the changes in brain lipidomics following prolonged and intermittent ischemic preconditioning. materials and methods two groups underwent bilateral common carotid artery occlusion either intermittently (for 3 continuous periods within a timeframe of 20 minutes, releasing 3 consecutive times, yielding a total of 9 minutes (intermittent bilateral ...

Background and Purpose: Infarct volume is one of the common indexes for assessing the extent of ischemic brain injury following focal cerebral ischemia. Accuracy in the measurement of infarct volume is compounded by postischemic brain edema that may increase brain volume in the infarcted region. We evaluated the effect of brain edema on infarct volume determined by triphenyltetrazolium chloride...
