the objective of present study was to investigate the effects of aqueous garlic extracts, vitamin e and n-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. twenty-five male rats were divided into five groups. animals within different treatment groups were maintained on their respective diets for 35 days as follows: grou...

introduction hyperglycemia increase oxidative stress which contributes to development and progression of diabetic complications. oxidative stress refers to an imbalance between the free radicals production and antioxidant defenses that led to tissue damage. lead is known to induce a broad range of physiological, biochemical, and behavioral dysfunctions on nervous systems, haemopoietic system, c...

Background: Lead (Pb) is a heavy metal that has devastating effects on many animal tissues. In this study we investigated the effects of orally-dosed lead acetate II on osteocalcin gene (osteocalcin) expression in mesenchymal stem cells grown in an osteogenic medium. Osteocalcin is an abundant bone matrix differentiation protein. Methods: Twelve male Wistar rats were divided into three groups ...

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...

Introduction: Lead is one of the most important environmental pollutants due to its vast use in various industries. Lead accumulation in different organs, especially the brain, liver and kidneys can cause serious health problems. Lead exposure is more dangerous during fetal period and childhood. Materials and Methods: Timed pregnant female rats divided into 6 groups. Group 1served as control g...

Background: Lead is known to be a highly toxic heavy metal which has a wide range of effect on human health. It has been proven that probiotics are able to bind heavy metals and remove them from the environment. In this study, the effect of Lactobacillus fermentum (L. fermentum) and its cytoplasmic extract were investigated on the hematological and body weight parameters in lead exposed rats. ...

background lead poisoning impairs memory and learning. objectives the protective effect of natural zeolite clinoptilolite on memory and learning impairment in rats exposed to lead acetate was investigated. materials and methods 60 male wistar rats in six groups treated for 2 months with diets contained different ratios of natural zeolite(i.e. 5% or 12.5%), and %0.2 lead acetate (la) concentrati...

The objective of present study was to investigate the effects of aqueous garlic extracts, vitamin E and N-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. Twenty-five male rats were divided into five groups. Animals within different treatment groups were maintained on their respective diets for 35 days as follows: grou...

  Urinary N-acetyl-β-D-glucosalninidase (NAG) has been proved to be a useful marker of early renal injury as a result of factors such as lead toxicity. In this study the effect of lead acetate on the kidney and its correlation with the nitric oxide (NO) system was investigated by determining the NAG release in perfused kidney of rat. Lead acetate caused a time- and dose-dependent increase in en...
