Glyphosate is the active ingredient and polyoxyethyleneamine, the major component, is the surfactant present in the herbicide Roundup formulation. The objective of this study was to analyze potential cytotoxicity of the Roundup and its fundamental substance (glyphosate). Albino male rats were intraperitoneally treated with sub-lethal concentration of(More)
Fenitrothion, endosulfan and abamectin are insecticides that affect various organs in humans and animals. The present study was conducted to investigate their cytotoxicity in isolated male rat hepatocytes. The study suggests that incubation of hepatocytes with 10 or 100 microM of each insecticide for 2h significantly decreased the cell viability. Increased(More)
The present study was undertaken to evaluate the effects of feeding the male mice with miso that was prepared with a mixture of microbial starters on the level of lipid peroxidation as a marker of oxidative stress, antioxidant power of hepatocytes, the enzymatic and non-enzymatic antioxidant. The starters that were used in the preparation of miso were(More)
BACKGROUND Sodium fluoride (NaF) intoxication is associated with oxidative stress and altered antioxidant defense mechanism. The present study was carried out to evaluate the potential protective role of blackberry and quercetin (Q) against NaF-induced oxidative stress and histological changes in liver, kidney, testis and brain tissues of rats. METHODS(More)
The present study was undertaken to assess the effect of the crude extract of Cleome droserifolia (CD) leaves on experimentally infected mice with Schistosoma mansoni. Two groups of mice, showing a patent infection of S. mansoni, one of them was daily treated with an alcoholic extract of CD leaves (0.31 g kg-1 body weight, i.p.) for 21 days. The(More)
The bivalve Ruditapes decussatus was evaluated as a possible biomonitor of heavy-metal contamination. Concentrations of copper (Cu), cobalt (Co), iron (Fe), nickel (Ni), and manganese (Mn) were measured in R. decussatus. Water and sediment samples were collected at two stations of Timsah Lake in Ismailia, Egypt, from October to November 2002, using atomic(More)
Chloroform (CHCl3) is widely used in the manufacture of drugs, cosmetics, plastics and cleaning agents. It is also found in chlorinated drinking water. This study was designed to investigate the toxic effect of CHCl3 on isolated male rat hepatocytes using several toxicity parameters. The hepatocytes were isolated by a collagenase perfusion technique and the(More)
Sodium azide (SA) is used as an active ingredient to control a broad spectrum of soil borne pathogens including insects, weeds, nematodes, fungi, and bacteria. The purpose of this study was to evaluate the ameliorator property of vitamin E (Vit E) or/and selenium (Se) against SA-induced injury in male mice at the biochemical, immunological and histological(More)
Coating with titanium oxides is a promising method to improve the blood compatibility of materials to be used for medical implants. However, biodegradation of the coating can result in microparticles that subsequently cause oxidative stress. Therefore, the present study was carried out to throw some light on the mechanisms affecting the reaction of tissue(More)
The present study aimed to investigate the efficacy of antioxidant defense system of the land snail Eobania vermiculata as biomarkers for terrestrial heavy metal pollution. For this reason, a set of biomarkers was performed on land snails E. vermiculata collected from polluted and non-polluted areas in the field. The biomarkers used were lactate(More)
