Antioxidant activity of aerial part of Cytisus scoparius, Link (Family Leguminosae) was studied both by in vitro and in vivo models. Different concentrations of different extracts of chloroform, ethyl acetate, methanol and hydroalcoholic extracts of plant were investigated for in vitro antioxidant activity using the thiocyanate method. The hydroalcoholic extract exhibited highest inhibitory ac...

The phototrophic bacterium Rhodobacter capsulatus contains a single, oxygen-responsive superoxide dismutase (SOD(Rc)) homologous to iron-containing superoxide dismutase enzymes. Recombinant SOD(Rc), however, displayed higher activity after refolding with Mn(2+), especially when the pH of the assay mixture was raised. SOD(Rc) isolated from Rhodobacter cells also preferentially contains manganese...

the effect of salinity was assessed on the activity of some major antioxidant enzymes i.e., superoxide dismutase (sod), peroxidase (pod), catalase (cat), in the seedlings’ roots or shoots of three winter canola (brassica napus l.) cultivars, colvert (tolerant), symbol (semi tolerant) and agat (susceptible). seedlings were treated with 0 (control), 50, 100 and 150 mm nacl for 24 h in hydropoic c...

Background: Our purpose was to investigate propolis and its component caffeic acid phenethyl ester (CAPE) for their antioxidant effects on the brain tissue of rats exposed to ionizing radiation (IR). Materials and Methods: Fifty-four male albino Sprague-Dawley rats, divided into six groups, were designed as normal control group, cranial irradiation of 5 Gray alone, irradiation plus CAPE, irradi...

background: blindness due to cataract is a major and important problem in pakistan. the problem is expected to increase in future due to increase in tobacco smoking. the aim of study was to look for the mechanism associated with metal deposition and its effect on antioxidant enzymes in lens of smokers in karachi, pakistan. methods: 20 cataract patients were randomly selected from out patient de...

Extracellular superoxide dismutase (EC-SOD), the only known enzymatic scavenger of extracellular superoxide, may modulate reactions of nitric oxide (NO) in the lungs by preventing reactions between superoxide and NO. The regulation of EC-SOD has not been examined in developing lungs. We hypothesize that EC-SOD plays a pivotal role in the response to increased oxygen tension and NO in the neonat...
