conclusions the primary treatment for gh-producing adenoma is surgery; however, this patient has high surgical risk from her severe cardiomyopathy. radiotherapy poses a greater risk because of increased cerebrovascular mortality. somatostatin receptor ligands are significantly associated with improvement of cardiovascular and hemodynamic parameters. dopamine agonists must be considered regardle...

background: the role of nitric oxide (no) of endothelial or neuronal origins in cerebral ischemia and reperfusion injuries are far from being settled, extending from being important to not having any role at all.    objective: to investigate the role of no of endothelial and neuronal origins in ischemia/reperfusion injuries in focal cerebral ischemia, l-name, a non selective no synthase inhibit...

Background: The role of nitric oxide (NO) of endothelial or neuronal origins in cerebral ischemia and reperfusion injuries are far from being settled, extending from being important to not having any role at all.  Objective: To investigate the role of NO of endothelial and neuronal origins in ischemia/reperfusion injuries in focal cerebral ischemia, L-NAME, a non selective NO synthase inhibitor...

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...

Background: Pentoxifylline (PTX) is used in human for intermittent claudication and cerebral vascular disorders including cerebrovascular dementia. It also inhibits the synthesis of tumor necrosis factor-α (TNF-α), which is believed to be neurotoxic in animal models of cerebral ischemia. The objective of this study was to examine the role of PTX on ischemia/reperfusion injures in rat model of t...

Introduction: Recent studies demonstrated that cannabidiol had neuroprotective property. Thereis some evidence about effective role of cannabidiol in reducing ischemic damages. It has been reported that infarct size is influenced by various factors after MCAO, including inflammatory factors. The aim of the present study was to evaluate the effect of cannabidiol on infarction volume and correlat...

introduction: several studies have indicated that late treatment of aminoguanidine (ag) reduces cerebral ischemic injuries in animal models. however, the effects of early treatment of ag on cerebral ischemic damage are not well understood. this study was designed to evaluate effect of early treatment of ag on cortex and striatum injuries as well as neurological dysfunctions in transient model o...

Introduction: Several studies have indicated that late treatment of aminoguanidine (AG) reduces cerebral ischemic injuries in animal models. However, the effects of early treatment of AG on cerebral ischemic damage are not well understood. This study was designed to evaluate effect of early treatment of AG on cortex and striatum injuries as well as neurological dysfunctions in transient mode...

Background: Hyperthyroidism as a risk factor for stroke is not conclusive. There are no definite data on the relationship between ischemic cerebrovascular injury and hyperthyroidism. This study was designed to define whether the outcomes of post-ischemic stroke injury are influenced by chronic hyperthyroidism. Methods: Two groups of hyperthyroid (HT) and control euthyroid rats of equal numbers ...
