even purified enzyme preparations are often heterogeneous. for example, preparations of aspartate aminotransferase or cytochrome oxidase can consist of several different forms of the enzyme.  for this reason we consider how different the kinetics of the reactions catalysed by a mixture of forms of an enzyme must be to provide some indication of the characteristics of the species present.  based...

hydatid disease is caused by the larva of echinococcus granulosus parasite. mebendazole (mbz) is used as an alternative choice for the treatment of the disease. aspartate aminotransferase (ast) is an essential enzyme in amino acid metabolism. the aim of the present study is to evaluate the effect of mbz on ast activity of hydatid cyst parasite in order to detect enzymatic parameter for drug eff...

Serum aspartate aminotransferase (SGOT), alanine aminotransferase (SGPT), creatinine phosphokinase (CPK), and butyric acid dehydrogenase (BDH) were determined in 94 patients before, 1(1/2) hours, and 24 hours after cardioversion. An increase in SGOT and CPK activity was observed 24 hours after cardioversion in the group of patients treated with two or more DC shocks. The importance of this enzy...

A dose-response experiment with seven supplemental pyridoxine levels (0, 0.66, 1.32, 1.98, 2.64, 3.30, and 3.96 mg/kg) was conducted to investigate the effects of pyridoxine on growth performance and plasma aminotransferases and homocysteine of White Pekin ducks and to estimate pyridoxine requirement for these birds. A total of 336 one-day-old male White Pekin ducks were divided to 7 experiment...

The effects of dietary food fortified with orotic acid (1.0%) on liver function were studied in rats. The rats fed with orotic acid promoted liver triglyceride content markedly, that was 5-fold higher than that of the control. The liver malondialdehyde (MDA) content increased by 10%, but the gluthation peroxidase (GSH-Px) activity decreased by 50%. The serum aspartate aminotransferase (AST) and...

The intra-subject correlations of three clinically meaningful combinations of serum constituents--(a) potassium, calcium, and albumin; (b) urea, creatinine, and uric acid; and (c) aspartate aminotransferase, lactate dehydrogenase, and alkaline phosphatase--were studied in 11 healthy men. Duplicate serum samples were obtained at 800 h, 1100 h, and 1400 h on five different days. All assays were p...

Magnesium aspartate, potassium aspartate, magnesium potassium aspartate, calcium aspartate, zinc aspartate, and copper aspartate as.Two aspartate aminotransferase EC 2. transfer of an amino group from aspartate to 2-oxoglutarate in order to form.Aspartate Aminotransferase AST in Refrigerated Serum NHANES 2001-2002. The AST catalyzes the reversible transamination of L-aspartate and. Abstract: Th...

freshwater fish cirrhinus mrigala were exposed to lethal concentration (5 mg/l) for 1,2,3,4 days and sublethal concentration (1 mg/l) for 1,7,14,21 days of cypermethrin to examine the enzymes activity, in functionally three different tissues namely, gill, liver and muscle. activities of aspartate aminotransferase (aat), alanine aminotransferase (alat) and glutamate dehydrogenase (gdh) increased...

The pathogenesis of idiopathic restless legs syndrome (iRLS) is not well established, but the most important hypothesis suggests dopaminergic dysfunction and iron deficiency. However, recent reports suggest a possible role for several neurotransmitters or neuromodulators, such as aspartate, glutamate, gamma-hydroxybutyric acid (GABA) and opiates, as well as relation with vitamin D deficiency. I...
