Scuba diving is associated with an important risk of devel­oping decompression sickness secondary to formation of gas bubbles inside the body. The latter is formed mainly by nitrogen in the body on the diver’s way to the surface (1,2). In some cases, it might injure the central nervous system. Several decompression cases that have been asso­ciated with neurologic symptoms are described in the l...

BACKGROUND AND PURPOSE We compared cranial computed tomography findings among 58 multi-infarct dementia index cases and 74 multi-infarct control subjects without cognitive impairment to identify potential determinants of multi-infarct dementia. METHODS The cranial computed tomography records of acute ischemic stroke patients with a history of multiple cerebral infarcts were compared to determ...

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...

Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...

We examined the brains of 14 patients (four men and 10 women, mean age 68.9 years) who died from brain herniation after cardioembolic stroke with persistent occlusion of the internal carotid-middle cerebral arterial axis. Our examination showed hemorrhagic infarct in seven patients and pale infarct in the other seven, contradicting the commonly proposed pathophysiologic mechanism for the develo...

Objective(s): Some histopathological alterations take place in the ischemic regions following brain ischemia. Recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. Here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...
