The effect of administration of carnitine on the severity of myocardial infarction in rats induced by isoproterenol was studied by following histopathological and biochemical parameters. Carnitine afforded partial protection against myocardial infarction. Serum aspartate amino transferase (GOT) and
BACKGROUND
The objective of this study was to compare the levels of troponin T and enzymes levels in myocardial infarction and skeletal muscle injury.
METHODS
This study was carried out at Basic Medical Sciences Institute, JPMC Karachi, Pakistan. Ninety subjects were selected. Thirty controls,
In 592 patients with an acute myocardial infarction different enzymatic estimations of the infarct size were compared. Heat stable lactate dehydrogenase (LD) was analysed every 12 hours for 48-108 hours. Aspartate amino transferase (ASAT) was analysed once daily for 3 days. In a subgroup creatine
The activity and the Km (Michaelis-Menten constant) of serum aspartate amino transferase (AST) were investigated in normal subjects, in patients with recent myocardial infarction, and in patients with infectious hepatitis. AST activity was elevated in both groups of patients. While the Km value of
Dietary fatty acids have cholesterol lowering, antiatherogenic, and antiarrhythmic properties that decrease the risk of myocardial infarction (MI). This study was designed to study the effects of various oils rich in either polyunsaturated (omega-3 or omega-6) fatty acids (PUFA) or saturated fatty
A total of 235 consecutive patients admitted to a coronary care unit were investigated for serum electrolyte and urea concentrations; activities of aspartate amino-transferase, lactate dehydrogenase, and lactate dehydrogenase isoenzymes; electrocardiographic changes; clinical state; and outcome.
The biochemical diagnosis of myocardial infarction is mainly based on assays of serum enzymes. The most commonly used markers are creatine kinase, lactic dehydrogenase and aspartate amino-transferase. They are useful to diagnose the infarction, determine its time of onset and evaluate its
There is increasing evidence that platelet thrombi play an important role in the pathogenesis of acute myocardial infarction (AMI). We compared "spontaneous" platelet aggregation in whole blood in 17 non-diabetic and 12 diabetic subjects on admission with AMI. There was no significant difference in
The effect of alpha-tocopherol (6 mg/100 g body wt, orally, daily for 90 days) pretreatment in isoproterenol (20 mg/100 g body wt, subcutaneously, twice at an interval of two days at the end of the alpha-tocopherol pretreatment) induced myocardial infarction was studied in rats. Isoproterenol
Cardiac necrosis was produced in rats by administering isoproterenol sulphate (85 mg/kg, sc for 4 days). The myocardial damage was proved by observing the elevated levels of serum aspartate amino-transferase, lactate dehydrogenase and creatine phosphokinase and the changes were confirmed by
Dynamic measurements in the cerebrospinal fluid (CSF) of the activities of lactate dehydrogenase (LDH), its first isoenzyme (LDH1), aspartate amino transferase (AsAT), alanine amino transferase (AlAT), creatine phosphokinase (CPK), gamma-glutamyl transpeptidase (GGT) and alkaline phosphatases (ALP)
The risk of pesticides on the human health and environment has drawn increasing attention. Today, new tools are developed to reduce pesticide adverse effects. This study aimed to evaluate the toxicity induced by, thiamethoxam (TMX), and the cytoprotective effect of a novel polysaccharide, named
A primigravida with idiopathic hypertrophic subaortic stenosis, New York Heart Association Classification III, developed acute chest pain with significant ST segment depression together with a new Q-wave in chest lead V6 on the electrocardiograph following delivery under lumbar epidural analgesia.
Sixty consecutive coronary patients operated on by the same team in 1992 were divided into two groups: group 1 (30 patients) using intermittent oxygenated cold Fresenius solution antegrade and retrograde (FR), group 2 (30 patients) using warm retrograde blood cardioplegia (WRC) with the Fremes
BACKGROUND
Chest pain or discomfort are infrequent complaints among women during labor and early puerperium, but when present they raise the suspicion of myocardial ischemia. The diagnosis of the latter is based upon serum elevatIon of certain enzymes, such as aspartate amino transferase, lactate
