Abstract: By applying Biological Signal Recording and Monitoring System, this paper aims to study influences of the herbicide glyphosate-isopropylammonium (GIA) on heart rate and electrocardiogram (ECG) of Bufo gargarizans Cantor. GIA solutions sprayed on the toads’ backs are absorbed through the skin and can effect cardiovascular function. Results show that as GIA concentrations increased, heart rate …

Abstract: The mast cells of lungs and heart have the reaction on the long, during 6 months, action of small doses of herbicides of dipyridylphosphate and roundup with the increase of their number and the increase of their functional activity, that become apparent uneven rise of degranulation. It is histochemical proved that these processes make …

Abstract: Glyphosate is the most commonly used herbicide in the world. Recent studies suggest that glyphosate-based herbicides (GBHs) have a higher toxicity towards animals than previously assumed by industry-funded studies. The EPA also lists glyphosate as being “practically nontoxic to fish, aquatic invertebrates….” Daphnia magna is an aquatic invertebrate and a well-established model organism for …

Abstract: The presence of DNA fragments in blood and milk from goats fed conventional (control) or Roundup Ready® soybean meal solvent extracted (s.e.; treated) was investigated by using a polymerase chain reaction approach. The same investigation was carried out on blood, skeletal muscle and organs from kids of both groups fed only dams’ milk until …

Abstract: Chlorophenoxy herbicides are widely used in the United States and Western Europe for broadleaf weed control in grain farming and park maintenance. Most of the spring and durum wheat produced in the United States is grown in Minnesota, Montana, North Dakota, and South Dakota, with more than 85% of the acreage treated with chlorophenoxy …

Abstract: The problems of the introduction of transgenic products into the consumer market were examined. The impact of the genetically modified potatoes on the cytological and morphological parameters in mice was investigated. An increase in body mass and in hearts mass and a decrease in spleens mass, degeneration of the ovaries and changing of the …

Abstract: The article is devoted to the introduction of transgenic products into the consumer market. The impact of the genetically modified potatoes on the cytological and morphological parameters of mice was investigated. Transgenic potato plants were produced by agrobacterium-mediated transformation using genetic constructions 35S-proSmAMP with marker gene npt11 of the resistance to the kanamycin. An increase in hearts …

Abstract: Glyphosate (N-(phosphonomethyl) glycine) is a most popular herbicide in agricultural practices throughout the world. It is possible that glyphosate spread in the ecosystems can reach plants, animals. The present work was directed to investigate the glyphosate residue in different organs of broiler chickens using ELISA and to study the possibility of its neutralisation using …

Abstract: The present study was undertaken to evaluate the effect of feeding Bt and non Bt cotton seeds on the liver of female albino rats. The experimental rats were divided in to three groups viz; control, Bt and non Bt group. They were fed Bt and non Bt cotton seeds at a dose of 2g/kg …

Abstract: The presence of DNA fragments in tissues from rabbits given genetically modified (GM) soya-bean meal (solvent extracted) was investigated by using the polymerase chain reaction (PCR) approach. Moreover, the possible effects on cell metabolism were evaluated by determination of several specific enzymes in serum, heart, skeletal muscle, liver and kidney. The chloroplast sequence for …

Abstract: The effects of genetically modified soybean feeding were evaluated in rabbits. Several enzymes were assayed in serum and tissue homogenates (hearth, skeletal muscle, liver, kidney) in order to reveal possible organ-specific alterations. Within the enzymes tested, lactic dehydrogenase showed significant differences in hearth and kidney. The electrophoretic analysis of LDH isoenzymes showed that LDH1 …

Abstract: Excessive amounts of the herbicide glyphosate are incorporated daily to the soil and the ecosystems. AMPA is its major environmental breakdown product. In this study we determined the levels of thiobarbituric acid reactive substances (TBARs); quantified superoxide dismutase (SOD) and catalase (CAT) activity in liver, kidney, lung and heart, and performed the comet assay …

Abstract: A significant degradation in the health of wild animals in Montana has been recorded over the past two decades. We surmise that the health issues are related to pesticide exposure. We present some of the evidence of the deterioration of the health in wildlife, which we used to inspire investigations on human health in …

Abstract: Glyphosate-based herbicides (GBHs) are widely used in agriculture. Recently, several animal and epidemiological studies have been conducted to understand the effects of these chemicals as an endocrine disruptor for the gonadal system. The aim of the present study was to determine whether GBHs could also disrupt the hypothalamic-pituitary-thyroid (HPT) axis. Female pregnant Wistar rats …

Abstract: Glyphosate residues in diferent organs and tissues as lungs, liver, kidney, brain, gut wall and heart of malformed euthanized one-day-old Danish piglets (N= 38) were tested using ELISA. All organs or tissues had glyphosate in diferent concentrations. The highest concentrations were seen in the lungs (Range 0.4-80 µg/ml) and hearts (Range 0.15-80 µg/ml). Te …

Abstract: Glyphosate (N-phosphonomethyl-glycine, GLP) is the most popular herbicide used worldwide. This study aimed to investigate the effects of glyphosate on rats’ liver function and induction of pathological changes in ion levels and oxidative stress in hepatic tissue. Sprague-Dawley rats were treated orally with 0, 5, 50, and 500 mg/kg body weight of the GLP. …

Abstract: The long-term feeding rats genetically modified soybeans for the first time revealed the presence of an aqueous extract of the internal organs of rats (liver, kidney, heart and lungs) biologically active compounds that stimulate reproduction and increase the viability of ciliates tetrahimena piriformis. Keywords: transgenic soybeans, rats, extract of the internal organs, ciliates, GM …

Abstract: The present study was designed to evaluate the impact of feeding a line of genetically modified cotton seeds (Bt cotton seeds) to that of standard diet and reference diet (Non-Bt cotton seeds) on growth, metabolism in albino rats. Non-Bt and Bt cotton seeds were incorporated into the diet of the albino rats at a …

Text: Genetically engineered (GE) crops have been a contentious issue from the start, with heated debate between supporters and detractors. Much of this exchange has taken place behind the scenes, inside regulatory bureaucracies. Recently, however, the debate about transgenic crops has re‐emerged into the public spotlight, driven by a convergence of environmental and economic concerns. …

Abstract: The analysis of the relevant part of the Institute of Nutrition Report showed that the studies were not carried out according to the accepted protocols for the biomedical assessment of GM food and feed (1). Many of the conclusions drawn by the authors do not correspond to the obtained data and therefore they are …

Abstract: To prevent health risk from environmental chemicals, particularly for progeny, we have studied the effects of the herbicide glyphosate on several enzymes of pregnant rats. Glyphosate is an organophosphorated nonselective agrochemical widely used in many countries including Argentina and acts after the sprout in a systemic way. We have studied three cytosolic enzymes: isocitrate …
