Introduction: Restoration of blood flow to the ischemic heart muscle causes infarction and myocyte death. Quercetin can be effective in treating heart disease due to its antioxidant effect, but its use is limited due to its low solubility in water. Quercetin restriction can be removed by embedding it in carrier nanoparticles. The present study was designed to determine the effect of quercetin e...
Background and purpose: Sesame oil (SO) is known to have antioxidant and anti-inflammatory properties and may produce protective effects against ischemic stroke-induced brain injuries. We examined the effects of treatment with SO on cerebral infarction and edema in a rat model of ischemic stroke. Materials and methods: Thirty male Sprague Dawley rats were divided into sham, ischemic, and isch...
Background and purpose: Ïn order to determine the presence of anticardiolipin (acl) antibodies in patients with ischemic events, a case control study was designed and performed. Materials and methods: 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 persons with no evidence of ischemic heart disease were selected for this study. Plasma samples were asses...
Background & Aims: According to the recent studies, fullerene nanoparticles have a potent scavenging property for free radicals in biological environments. Since reactive oxygen species (ROS) is a fundamental mechanism of brain damage in stroke, we aimed to evaluate the neuroprotective effects of fullerene nanoparticles on ischemia-induced brain injuries in experimental model of stroke...
Serum IgE and beta 2 microglobulin levels were determined in 31 patients suffering from acute myocardial infarction and 30 patients with other forms of ischemic heart disease. The levels of these parameters were studied on the first, third and seventh day after the onset of disease. The immunological method used for the determinations was ELISA Patients with myocardial infarction showed an...
background: the role of renin angiotensin system (ras) in ischemic/reperfusion (i/r) injuries is not fully elucidated. furthermore, it is not clear whether inhibition of ras by angiotensin-converting enzyme (ace) inhibitors has beneficial effects in terms of protecting the brain from i/r injuries. in this study enalapril is used as an ace inhibitor to evaluate the role of ras in i/r injuries in...
Myxoma may cause systemic embolization and frequently presents as ischemic stroke. There has been debates whether it is safe to use recombinant tissue plasminogen activator (rt-PA) in patients with cardiac myxoma who are presented with ischemic stroke at emergency department. we describe a young case of atrial myxoma with initial presentation of acute cerebral infarction symptoms who was treate...
Background: The role of Renin Angiotensin System (RAS) in ischemic/reperfusion (I/R) injuries is not fully elucidated. Furthermore, it is not clear whether inhibition of RAS by Angiotensin-Converting Enzyme (ACE) inhibitors has beneficial effects in terms of protecting the brain from I/R injuries. In this study enalapril is used as an ACE inhibitor to evaluate the role of RAS in I/R injuries in...
myocardial ischemia (mi) resulting in infarction is an important cause of mortality and morbidity worldwide. acute ischaemia rapidly impairs myocardial contractile function. myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. hibernation is now thought to be the consequence o...
background and purpose: ischemic heart diseases (ihd) is getting as the most common and the main causes of heart diseases and mortalities worldwide affecting the quality of life (qol) of the patients. this study was conducted to determine the qol for the patients with ihd referring to medical centers of kashan in 2007. methods: this cross-sectional study was performed on all patients (n =500) r...
