the effects of lead on the proline content and dry weight of leaves and roots were investigated in two canola cultivars (brassica napus l.) grown in the hoagland solution. the growth of treated plants was inhibited under lead stress. lead induced differential accumulation of proline in canola grown in solution with the addition of 0, 100 and 200 mgl-1 of pb. hyola308 cultivar showed low biomass...

conclusions lead contamination in the presence of an emf exacerbates the oxidative damage to plasma proteins as well as the conformational changes in hb. an artificial neural network can be used as a predictive tool for the oxidative danger posed to workers in industrial fields, battery manufacturing companies, and power plants. patients and methods in this experimental study, the blood samples...

materials exhibit significant creep behavior at temperatures above 40% of their absolute melt temperature. lead, tin and their alloys are such materials which experience significant creep behavior in room temperature. one of the most important applications of the tin-lead alloys is soldering electronic circuits in electronic industry, and for lead are isolation walls and wet batteries. room tem...

since industrial revolution heavy metals such as lead (pb) and cadmium (cd) have been extensively dispersed in environment which, unknown biological effects and prolong biological half-life make them as a major hazard to human health. in addition, the sharp increase in multiple sclerosis incidence rates has been recorded in iran. the propose of this study was to measuring blood lead and cadmium...

Background: The role that stress plays in infertility remains controversial and despite medical advances a large percentage of infertility remains unexplained. Clinicians and researchers consistently report that infertile women view infertility and its treatment as extremely stressful. Basic science has elucidated the linkages between the hypothalamic-pituitary axis (HPA) and hypothalamic-pitui...

background: this study was performed to investigate the adverse effects of acute lead intoxication on hemogram, erythrocyte osmotic fragility and oxidant/antioxidant status and the probable ameliorating effect of silymarin in comparison to d-penicillamine. methods: forty-eight albino rats were divided in 8 groups and received the following treatments in a 10 day experiment in shahid chamran uni...

the objective of this study was to evaluate the effect of dietary supplements with lead acetate and aluminosilicates (atn) on antioxidative enzyme activities and lipid peroxidation of the heart and skeletal muscle tissues of broiler chickens. broilers were allotted to four diets including the control group, the pb group, the aluminosilicate-atn (antitoxic nutrient) group and the pb+atn group, i...

background: lead toxicity is a prevalent health problem in both developed and developing countries. one of the proposed mechanisms for lead-induced organ damage is oxidative stress. oxidative stress is well-associated with the pregnancy disorder, pre-eclampsia. exposure to lead may be one of the sources of the oxidative stress that leads to development of pre-eclampsia in pregnant women. object...
