The purpose of this study was to evaluate the influence of zafirlukast (Z), quercetin (Q) and their combination on baroreflex sensitivity (BRS), endothelin-1 (E1) plasma concentration and the severity of ventricular arrhythmias (VA) occurring during myocardial infarction (MI). In anaesthetized
Reperfusion injury is remarkable clinical issue that needs to be resolved as ischemia-reperfusion is a common phenomenon encountered in numerous clinical situations. The present communication report the involvement of nitric oxide (NO) in cardioprotection offered by flavonoids (rutin and quercetin)
Mitochondrial dysfunction plays an important role in the pathology of myocardial infarction. We evaluated the combined protective effects of quercetin and α-tocopherol on mitochondrial damage and myocardial infarct size in isoproterenol-induced myocardia- infarcted rats. Rats were pretreated with
To investigate the protective mechanism of quercetin on acute myocardial infarction (AMI) rats, an AMI rat model was established by ligating the left coronary anterior descending branch. The rats were randomly divided into the model group and low- and high-dose quercetin groups. The control group
BACKGROUND
Reperfusion therapy used in the treatment of cerebral ischemia often causes reperfusion neurological injury. Multiple pathological processes are involved in this injury including oxidative stress and components of the inflammatory response appear to play key roles in these deleterious
OBJECTIVE
Revascularization therapy is the mainstay of treatment in the management of myocardial infarction in normal and diabetic patients. We attempted to evaluate the cardioprotective actions of quercetin and rutin in ischaemia-reperfusion-induced myocardial infarction in both normal and diabetic
In experimental canine myocardial infarction induced by an hour coronary artery occlusion, followed by 5-hour reperfusion, quercetin solution, 10 mg/kg, was demonstrated to improve left ventricular myocardial contractility, to reduce the incidence of rhythm and conduction disturbances, to promote
BACKGROUND
Chungsim-Yeunja-Tang (CYT) has been used as a medicine for cerebral infarction (CI) patients in Korea. The objective of this study was to determine precisely the effect of CYT on CI patients using peripheral blood mononuclear cells (PBMCs).
METHODS
For a clinical study, 47 CI patients
In experimental myocardial infarction in dogs caused by 60-minute occlusion of the coronary artery with the subsequent 24-hour reperfusion, the administration of quercetin solution (50 mg/kg) was found to improve the contractile function of the left ventricular myocardium, to decrease the incidence
The present study aims to evaluate the combined protective effects of quercetin and α-tocopherol on isoproterenol-treated myocardial infarcted rats. Male albino Wistar rats were pretreated with a combination of quercetin (10 mg/kg) and α-tocopherol (10 mg/kg) daily for 14 days. After the
Background: At present, there is no effective therapy for preventing myocardial ischemia reperfusion injury (MIRI), and it is inevitable. The methods how to effectively decrease MIRI have attracted the attention of medical researches in
One of the major instigators to neuronal cell death and brain damage following cerebral ischemia is calcium dysregulation. The intracellular calcium overload resulting from glutamate excitotoxicity is considered a major determinant for neuronal loss during cerebral ischemia. Moreover, ASIC1a
Sophora Japonica L. (SJ) is a traditional Chinese herb used to cool blood, stop bleeding and to treat hemorrhoids with bleeding. Although several recent studies found that both SJ and Ginkgo biloba have the same components of quercetin and rutin, only Ginkgo biloba has been widely used to treat
Studies have shown that intake of quercetin was inversely associated with mortality from coronary heart disease. Since recent studies documented that disruption of atherosclerotic plaques is the key event triggering acute myocardial infarction, and vascular endothelium-derived matrix
This study was aimed to evaluate the combined effects of quercetin and alpha-tocopherol on lipid metabolism and glycoprotein components in isoproterenol induced myocardial infarction in Wistar rats. Myocardial infarction in rats was induced by isoproterenol (100mg/kg) at an interval of 24h for 2
