to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...

drought is an important abiotic stress limiting plant performance. generation of reactive oxygen species (ros) is enhanced under stresses. two greenhouse experiments were conducted to evaluate the effect of phytohormones on the changes of antioxidant enzymes and carotenoids in petals of pot marigold (calendula officinalis l.) under drought stress. results showed that the activities of superoxid...

In the present study a hydroalcoholic extract of Syzygium cumini seeds have been investigated for its antioxidant activity in aspirin induced peptic ulcer in rats with the aim of exploring possible correlation between its antioxidant and antiulcer activities. Oxygen free radicals are considered to be important factors in the pathogenesis of peptic ulcer. The level of lipid peroxide was elevated...

objectives: hyperlipidemia can cause a variety of diseases such as atherosclerosis, diabetes, and fatty liver which is followed by increased liver enzymes. since berberis vulgaris (b. vulgaris) root possesses antioxidant properties, the present study was conducted to investigate the effect ofits extract on the activity of liver enzymes in rats. materials and methods: in this experimental study,...

background: withania somnifera l. dunal, (ashwagandha) belongs to the family solanaceae and is known as ‘indian ginseng’ in the traditional system of medicine. objectives: in the present investigation, comparative analysis was carried out between two different ecotypes of w. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (cat), superoxide dismutase (sod) an...

ferula gummosa boiss is a good source of biologically active compounds such as monoterpene and sesquiterpene derivatives. there are also several reports on antioxidant effects of these compounds. the aim of this study was to investigate the effect of daily administration of f. gummosa root hydro-alcoholic extract on serum oxidant-antioxidant status. twenty four wistar rats were randomly divided...

phytochemical constituents, such as total phenol, allicin and pyrovic acid as well as antioxidant activity of thirteen ecotypes of allium hirtifolium boiss. from different regions of iran were evaluated. average contents of total phenol, allicin and pyrovic acid of bulbs extracts per g fresh weight were 0.647 mg gallic acid equivalent (gae), 2.127 mg and 84.412 µmol, respectively and antioxidan...

The number of patients with end-stage renal disease is growing rapidly in Asia. Patients with end stage renal disease failure (ESRD) undergoing long term hemodialysis (HD) are at risk for high oxidative stress. There is paucity of information with regard to oxidative stress during HD. Therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...

conclusions gallic acid and csa combination improved antioxidant capacity and cell membrane integrity more than each one alone. therefore, it can be a therapeutic approach to reduce the i/r injury. background myocardial infarction is one of the important causes of death during old ages. gallic acid as an antioxidant or cyclosporine a (csa) as inhibitor of mitochondrial permeability transition p...
