In order to know the precise quantity of catalase protein in acatalasemic and hypocatalasemic blood, immunological studies were conducted using hemolysates or acetone extracts of those blood as antigen. 1) The ratio of catalase contained in normal, hypocatalasemic and acatalasemic blood, calculated from precipitates produced in the reaction between catalase antibody and hemolysates was 1.0 : 0....

Background: Hyperglycemia in diabetic people resulted in oxidative conditions. Propolis is the third most important component of bee products which has various functional properties such as anti-oxidant due to its components. The aim of this study was to evaluate the propolis effect on fructosamine level, the catalase activity, and the level of oxidized LDL changes in type 2 diabetic patients. ...

The concentration of catalase protein in anemic blood with enhanced population of reticulocytes and in non-anemic blood was determined immunologically by double diffusion test with anti-mome-liver catalase rabbit serum. The change in catalase protein concentration in anemic blood during incubation at 37◦C for 24 hours was also studied. It was indicated that the diminished catalase activity in a...

because of the harmful effects of the chemicals on human health and environment, the use of these compounds is recently restricted and it is necessary to use the safe compounds in postharvest technology of fruits and vegetables. in this study, the effect of salicylic acid (sa; at concentrations of 0, 1, and 2 mmol l-1) and aloe vera gel (at concentrations of 25 and 33 %1) application on posthar...

The activities of the endogenous O2- and H2O2 scavenging enzymes, superoxide dismutase (SOD), glutathionine peroxidase (GP), and catalase, were measured in lysates of the intracellular parasite, Toxoplasma gondii, and in various macrophage populations. During 72 h of cultivation in standard medium alone, the catalase activity of in vivo-activated toxoplasma-immune macrophages (IM) and immune-bo...

understanding the physiological processes associated with drought stress lead to an understanding of the basic mechanisms of resistance, maintaining yield potential and contribute to the identification of drought tolerant cultivars. for this purpose, the effects of drought stress in cowpea genotypes was evaluated using five different genotypes with different yield potential in a pot experiment ...

an experiment was conducted to determine the aging mechanism in safflower seed using natural aging treatment (storing seed at room temperature for six years) and accelerated aging ( incubating the seed at 41?c and close to 100% relative humidity for 4 ,8 and 12 days). the results indicated that both natural and accelerated aging reduced germination percentage, seed vigor and activity of catalas...
