The techniques employed included transmission electron microscopy, differential scanning calorimetry and Fourier transform infrared spectroscopy. The mortality rate was DNA damage in grasshopper Chorthippus brunneus Orthoptera hatchlings following paraquat exposure. Data intoxicacon retrieved in March from the Scopus database.

The calibration curve in the 0. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. We included all patients admitted to a tertiary general hospital in Taiwan between and following a suicide attempt by paraquat self-administration.

A detection limit of 0. Results There was a positive correlation between the risk of death and admission time, poisonous dose, the concentration of urine paraquatand white blood cell count P paraquat poisoning.

According to different period of poisoning, the 6 cases were divided into 3 stages: There was increasing research output in the field of paraquat intoxication during the period Transcriptome profiling to discover putative genes associated with paraquat resistance in goosegrass Eleusine indica L.

Intoxicación por paraquat

Paraquat PQ is toxic herbicide considerable evidence suggests that oxidative stress and mitochondrial dysfunction contribute to PQ toxicity. Los traumatismos y envenenamientos ocuparon el primer lugar en la mortalidad del grupo adolescente tasa de Subscriber If you already have your login data, please click here. Combined exposure to paraquat and maneb is a latent risk factor for many diseases, particularly those of the central nervous system, including Parkinson’s disease and Alzheimer’s disease.


Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The wavelengths for detecting the concentration of serum PQ by common and second-derivative spectrophotometry were determined.

The use of desiccants on maize crop may benefit farmers, especially by anticipating soil availability for the establishment of a new crop, and for the earlier commercialization of the product. 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.

Serum paraquat concentration detected by spectrophotometry in patients with paraquat poisoning. We evaluated their radiographic findings and the differences in imaging features based on mortality.

We employed change point analysis to determine the effect of paraquat prohibition on suicide rate over time, and pot results were verified by structural change analysis, an alternative statistical method. The theoretical results, in particular using Mopac procedures, were in agreement with the experimental findings. The protective gramoxne of MWCNT on MV toxicity on the root surface area could be quantitatively explained by the extent of MV adsorption on MWCNT and was related to stimulation of photosynthesis, antioxidant protection and number and area of lateral roots which in turn helped nutrient assimilation.

Effect of low doses of herbicide paraquat on antioxidant defense in Drosophila. Paraquat prohibition should be considered as a national suicide intoxicacipn strategy in developing and developed countries alongside careful observation for method substitution effects.

In individuals surviving the acute phase, pulmonary fibrosis develops. Simultaneously, rats in the control group were administered normal saline. The genes related to polyamines and transport are likely grqmoxone candidate genes that could be further investigated to confirm their roles in paraquat resistance of goosegrass. Spectrophotometry, including common spectrophotometry and second-derivative spectrophotometry, is commonly used for PQ detection in primary hospitals.


The herbicide paraquat is associated with a high mortality rate.

Rotenone and paraquat perturb dopamine metabolism: P Q in included in the p-tert butylcalix a rene cavity, a situation favoured by its pinched conformation in polar solvent while it is partially included in the p-tert butylcalix a rene cavity because of its in-out cone conformation.

From Monday to Friday from 9 a. We have studied the effect of the paraquat prohibition on the national suicide rate and method of suicide in South Korea. When paraquat was applied to cochlear organotypic cultures, it not only damaged the outer hair cells OHCs and inner hair cells IHCsbut also caused dislocation of the hair cell rows.

Pulmonary irradiation was started within 24 hours after admission from day 1 to day 11 after ingestion of paraquat. We report the case of a snapping turtle Chelydra serpentina found tetanized, with the limbs in extension, mydriasis and poor response to external stimuli, in whose terrarium was found a Tityus trivittatus scorpion. In this cross sectional study, medical records of all paraquat intoxicated patients were reviewed at Taleghani hospital of Urmia, Iran, from to Renal function, namely creatinine clearance, was the most significant covariate to explain between patient variability in paraquat clearance.

The Length of hospital stay was 5. All of the patients ere managed with aggressive supportive treatment such as gastric lavage, forced diuresis, antioxidant agents and antifibrosis agents.
