Intensification of brain injury and blood-brain barrier permeability by short-term hypertension in experimental model of brain ischemia/reperfusion

Introduction: Arterial hypertension is one of the causes of stroke, and as one of the vasculotoxic conditions intensifies ischemic stroke complications. The aim of the present study was to analyze the effects of short-term cerebral hypertension on ischemia/reperfusion injury and pathogenesis of ischemic stroke. Methods: The experiments were performed on three groups of rats (N=36) Sham, cont...

Inhibition of nitric oxide synthase activity improves focal cerebral damage induced by cerebral ischemia/reperfusion in normotensive rats

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...

P188: The Role of Cryotherapy in Progression of Brain Stroke

Stroke is a leading cause of mortality and morbidity in developed countries and has increased incidence due to progression of average population age. Pharmalogical and mechanical reperfusion therapy, as primary therapeutic approaches, are only applicable to less than 10% of patients with a 50-70% efficacy. but about 90%of patients are severe restricted to these treatments. Glutamate excitotoxic...

A comprehensive approach to investigate the contradictory effects of metformin therapy in cerebral ischemic injury

Ischemic brain injury involves a complex sequence of excitetoxic and oxidative events. Metformin is proposed as one of the potential candidates for returning the body to its basic homeostasis in ischemic situations. Metformin can either protect or damage cells by activating AMP-activated protein kinase (AMPK) and its downstream factors so, it has a dual role in the cerebral ischemia context, bu...
