Development of a technically simple yet effective method for paraquat PQ detection is of great importance due to its high clinical and environmental relevance.


Binding of paraquat to cell walls of paraquat resistant and susceptible biotypes of Hordeum glaucum. Paraquat is a nonselective contact herbicide of great toxicological importance, being associated with high mortality rates, mainly due to respiratory failure. Prognostic methods for paraquat poisoning We found 18 studies that reported a link between the result of investigations and outcome. Efeito de doses reduzidas de glyphosate e paraquat simulando deriva na cultura do milho Effect of reduced rates of glyphosate and pzraquat simulating drift in corn crop.

Mortality in control and treatment groups varied markedly between studies. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.

The severity and outcome was determined primarily by the amount of paraquat ingested.


Paraquat is the best-selling herbicide throughout the world, It is absorbed by the digestive and inhalatory routes. Among these, 25, unigenes were assigned to 65 GO terms that contained three main categories.

Finding of CT and clinical in paraquat poisoning pulmonary injury. Female and male Sprague-Dawley rats were mated female: Paraquat adsorption on NaY was Paraquat -induced pulmonary toxicity, therefore, is a potentially useful model paraqiat evaluation of oxidant mechanisms of toxicity. Other features suggest that most patients were not significantly poisoned: Paraquat is considered to be the main pesticide involved in accidental and intentional poisoning, and is responsible for a high rate of morbidity and mortality.

Time-related lethal blood concentrations from acute human poisoning of chemicals. Discussion We were unable to find any study that definitively established the role of immunosuppression in paraquat paraquxt. Cyclophosphamide treatment of paraquat poisoning.

gramoxone paraquat herbicide: Topics by

Pulmonary irradiation was started within 24 hours after admission from day 1 to day 11 after ingestion of paraquat. Tests showed that soil sorption of paraquateither free or associated with the nanoparticles, was dependent on the quantity of organic matter present. Therefore, we designed this nationwide large-scale population-based retrospective cohort study to investigate the outcome of paraquat poisoning with hemoperfusion and the additional effects of IST combined with hemoperfusion.

In the absence of such an assay, the urine dithionite test is often used to estimate the level of exposure. No significant differences between cell wall, characteristics of resistant and susceptible biotypes of H.

Handbook of pesticide toxicology. The radiomimetic effect of paraquatalone and in combination with X-rays, was examined.

Six patients who ingested paraquat underwent sequential follow-up CT scanning during a period of at least six months, and the results were analysed. Do you really want to delete this prezi?


Seletividade de herbicidas registrados para a cultura do milho a adultos de Trichogramma pretiosum Hymenoptera: The results showed that the application of paraquat caused strong bradikinesia, postural instability and paraquah.

Paraquat bis hexafluorophosphate undergoes stepwise dissociation in acetone. The best responses were obtained with differential pulse voltammetry in 0. Here we found that Wld S significantly reduced the cytotoxicity of bipyridylium herbicides paraquat and diquat in mouse embryonic fibroblasts, but had no effect on the cytotoxicity induced by chromium VI, hydrogen peroxide, etoposide, tunicamycin or brefeldin A.

Furthermore, characterization of the consequences of intracellular redox cycling of xenobiotics will no doubt provide basic information regarding the role of this phenomena in the development of chemical toxicity.

High dose cyclophosphamide and dexamethasone in paraquat poisoning: Onion plants, from direct sowing to the field, are more damaged by mechanical cultivation and more sensitive to herbicidesespecially to broadleaf herbicidesthan transplanted onions. The clinical pathology process of paraquat poisoning was in line with CT finding which was related with clinical stage and was helpful for clinical assessment of paraquat poisoning promptly and to guide the clinical treatment.

Key words paraquat poisoning.

To determine the long-term follow-up CT findings of paraquat -induced lung injury.
