Short-term salt (NaCl) treatment on Aegiceras corniculatum in roots and leaves showed no change in fresh and dry weight of leaves, roots and leaf area. There was no significant change in total soluble root protein, photosynthetic pigments of leaves and spectral characteristics of thylakoids. However, the activity of antioxidative enzymes (catalase, ascorbate peroxidase and guaiacol peroxidase) ...

The efftct was assessed of paraquat administration on the antioxidative defense mechanism in blood and liver. Ten-week-old senescefice-accelerated miee were fed with either a 209t6 casein diet or the same diet supp]emented with 200 ppm paraquat for 12 weeks. About O.2 m] of bloed withdrawn periodically from the supraorbital yein was assayed for the activities of antioxidatiye enzymes and oxidat...

Anthropogenic activities have caused important increases in soil Cu levels not only in urban areas but also in croplands. This study was designed to find out the effect of different concentration of copper on physiological and biochemical changes in Eucalyptus camaldulensis seedlings. Seeds of Eucalyptus camaldulensis were grown in marble chips and irrigated with nutrient solution mixed with co...

The protective antioxidative effect of the phenolic extract (PE) isolated from Salix viminalis pyrolysis derived bio-oil was shown in vitro on the Chinese hamster ovary (CHO) cells exposed to hydrogen peroxide (H2O2). Cells pretreated with 0.05 μg/ml PE after exposure to different concentrations of H2O2 (300-900 μM) showed up to 25 % higher viability than the unpretreated ones. The antioxidativ...

synthetic sulphonated anthraquinones are the raw materials used for producing a large palette of synthetic dyes, and microorganisms have a limited ability to decompose them, hence they are one of the important environmental pollutants. in order to study the ability of plants to remove this pollutant from the environment, corn, as a plant not containing any natural anthraquinones and common sorr...

Cyanobacteria are autotrophic prokaryotes with excellent antioxidative system that scavenges reactive oxygen species produced during photosynthesis. Superoxide dismutase (SOD) represent the primary defence against oxygen damage. The antioxidative activity of SOD enzymes was determined in cultures of the bloom forming cyanobacteria Anabaena variabilis and Synechococcus elongates. Experimental re...

The alleviation of oxidative damage and increased resistance to salt stress and to non-ionic osmotic stress induced by 100 mM NaCl or 100 mOsm polyethylene glycol (PEG) treatments, respectively, often correlate with a more efficient antioxidative defence systems and detoxification mechanisms. Pre-treatment of plants with salicylic acid (SA) enhanced antioxidant enzyme activities in concentratio...

Trans-resveratrol, a phytoalexin produced by a variety of plants, has been shown to inhibit oxidative enzymes in an animal cell system. Its effect on several oxidative and antioxidative enzymes from plants was investigated using in vitro assays. Trans-resveratrol inhibited superoxide dismutase, lipoxygenase, catalase, peroxidase, polyphenol oxidase, and 1-aminocyclopropane-1-carboxylic acid oxi...

some reports indicated that terpenoides allochemicals material induced oxidative stresses during seed germination phase. α-pinnen, as one of important allechemical monoterpenoids, reported from species of several plant family and especially ferula flabelliloba from apiaceae. in order to investigate the allelopatic effect of f. flabelliloba and the time of sampling on physiological and biochemic...

OBJECTIVES To investigate the activities of the main antioxidative enzymes and oxidative stress in women with depressive disorder (DD). METHODS In 35 drug-naive women with DD and 35 age matched healthy women enzymes superoxide dismutase (CuZnSOD), catalase (CAT), glutathione peroxidase (GPX1), glutathione reductase (GR) and paraoxonase (PON1), concentrations of conjugated dienes (CD), reduced...
