Increased production of free radicals under oxidative stress conditions plays a vital role in the impairment of endothelial function and also in the pathogenesis of ischemic heart diseases. Ischemia, followed by reperfusion, leads to the exacerbated formation of oxy- free radicals. These reactive oxygen species through a chain of reactions damage the cardiomyocytes and cause more injury to the ...

Hydrogen sulfide (H2S) has been reported to be interwined in multiple systems, specifically in the cardiovascular system. However, the mechanisms underlying remain controversial. In the present study, we assessed the cardio-protective effects of H2S in the rat hemorrhagic shock model. Hemorrhagic shock was induced in adult male Sprague-Dawley rats by drawing blood from the femoral artery to mai...

Silymarin ‘milk thistle’ (Silybum marianum) plant, has been used for years treatment of different diseases such as liver and gallbladder disorders, protecting against snake bite insect stings, mushroom poisoning alcohol abuse. antioxidant, anti-lipid peroxidative, antifibrotic, anti-inflammatory, immunomodulatory, regeneration activities. The cardioprotective activities silymarin were primarily...

The current study dealt with the protective role of garlic oil on isoproterenol (ISO)-induced myocardial infarction (MI) in rats. Subcutaneous injection of ISO (20 mg/kg body weight in1ml saline) to rats for 2 consecutive days offered significant alteration in biochemical parameters and moderate necrosis in heart. Effect of garlic oil oral treatment for 60 days (75 mg /kg body weight) was evalu...

In a randomised, double-blind placebo-controlled trial, the effects of the administration of oral L-carnitine (2 g/day) for 28 days were compared in the management of 51 (carnitine group) and 50 (placebo group) patients with suspected acute myocardial infarction. At study entry, the extent of cardiac disease, cardiac enzymes and lipid peroxides were comparable between the groups, although both ...

Objective: The present study aimed to evaluate the effect of pre-treatment with taurine on rats in which MI had been induced using isoproterenol (ISO). Methods: Rats were randomly allocated into three groups; the 1st group is the normal control (C) one, the 2nd is the isoproterenol cardiotoxic (ISO) one and the 3rd group is the taurine pretreated (T-ISO) one. Results: The activities of the card...

BACKGROUND Fractures of the sternum may be associated with major injuries to thoracic organs, with serious consequences. OBJECTIVE To assess the hospital course of patients diagnosed with isolated sternal fracture. METHODS We reviewed 55 medical records of patients who were admitted with isolated sternal fracture to the emergency department during the period January 1990 through August 1999...

The polymorphonuclear granulocyte, or neutrophil, has been implicated as a mediator of tissue-destructive events because it releases the preformed proteolytic enzymes elastase and cathepsin G, and, as a result of myeloperoxidase action, hypochlorous acid. We show that elastase inactivates and fragments creatine kinase isoenzymes CK-2 and CK-3, and, to a lesser extent, lactate dehydrogenase (LD)...

Serum cardiac enzyme levels (CK, LDH, SGOT) were estimated and the ECG recorded for 4 days following admission of 288 patients (Group I) to a stroke intensive care unit. Sixty-four of these patients, subsequently found not to have strokes, served as controls. Mean serum levels of all 3 cardiac enzymes were elevated in 8% of the 224 patients with stroke. The mean serum enzyme levels in patients ...

The present study was designed to investigate the cardioprotective effects of Malaysian Tualang honey against isoproterenol- (ISO-) induced myocardial infarction (MI) in rats by investigating changes in the levels of cardiac marker enzymes, cardiac troponin I (cTnI), triglycerides (TG), total cholesterol (TC), lipid peroxidation (LPO) products, and antioxidant defense system combined with histo...
