The effect of heparin on the activity of lipoprotein lipase from bovine milk was investigated under conditions varying with regard to ionic strength, purity of enzyme, and mode of substrate activation. A crude enzyme (dialyzed skim milk) was studied, along with a purified preparation obtained by affinity chromatography on a column of heparin-substituted agarose. Serum, high density lipoproteins...

Creatine kinase (CK) is an enzyme that produces and uses phosphocreatine to transfer energy maintain tissue cellular homeostasis, being considered the main controller of homeostasis. Its activity in plasma/serum has been commonly used evaluate damage, since CK released into bloodstream during damage. This review summarizes current knowledge regarding use fish, focusing on its potential as indic...

A study was made on serum and urinary muramidase in 56 patients with leukemia and other hematologic disorders. Serum and urinary muramidase levels prior to antileukemic therapy were elevated in monocytic leukemia, while not so increased in paramyeloblastic leukemia. In all patients with acute lymphocytic leukemia pretreatment serum enzyme activities were decreased below normal, whereas those in...

Two lots of white rats ( Wistar ) were treated for 5 days and respectively 10 days with low intensity and frequency electromagnetic field (100 Hz, 2.7 mT) discontinuous applied ( 3 second action and 1 second break). Other two lots of rats were untreated controls for 5 and respectively 10 days. The treatment induced an intensification of α – amylase enzyme activity from rats blood serum, compara...

a total of 781 serum and 827 red cell samples from four populations of iran (kashan, ardestan, asrara and ardabil) were sub-typed by isoelectric focusing for group-specific componet and red cell enzyme phosphoglucomutase, locus one, respectively. heterogeneity test revealed no significant differences among the populations studied regarding both pgm1 and gc systems.

The responses of liver and serum gluta­mate dehydrogenase (CDII; EC 1.4.1.2.), isocitrate (ICDH; 1.1. 1.42) the urea cycle enzyme, ornithine carbamoyltransferase (OCT; 2. 1.3.3) to dietary lima bean haemagglutinin (lectin) were assessed using a total S4 growing rats. GDH ICDH activities in highly significantly (P < 0.001) eleva­ted by haemagglutinin. activi­ties correlated 0.01) with levels ...

Background: Recurrent aphthous stomatitis (RAS) is a common disease characterized by repeated formation of non-contagious and benign oral ulcers. It triggered different factors its cause not completely understood. This study aimed to evaluate the role serotonin in patients with RAS, compared that control subjects. Subjects Methods: Present involved 100 participants which 50 subjects diagnosed R...

SYNOPSIS The antitrypsin activity of human serum was studied as a function ofpH, preincubation of serum with trypsin, and the concentrations of substrate, trypsin, and serum. Maximal activity was observed between pH 8-0 and 8-3. Activity was enhanced by preincubation of serum with trypsin, and reduced by high concentrations of trypsin and substrate. Percentage inhibition was a sigmoid function ...

The antitrypsin activity of human serum was studied as a function of pH, preincubation of serum with trypsin, and the concentrations of substrate, trypsin, and serum. Maximal activity was observed between pH 8.0 and 8.3. Activity was enhanced by preincubation of serum with trypsin, and reduced by high concentrations of trypsin and substrate. Percentage inhibition was a sigmoid function of log s...
