Moreover, the composite adsorbed blue dye from a commercial grade paraquat.


Methods Thirty-seven patients with acute paraquat poisoning from June to Intoxicqcion were enrolled. PQ serum levels decreased in all groups after 72 h of treatment p treatment group.

He was treated with local care, analgesics, and steroids. Further legislative interventions to prevent the easy availability of highly lethal suicide methods are recommended for reducing the number of suicides worldwide. The average recovery rates of PQ were within a range of This Spanish-language Digest summarizes some of the causes and effects of childhood lead poisoning and suggests some lead poisoning prevention strategies…. Paraquatplumbagin, menadione, and phenazine methosulfate are known to generate superoxide radical anions via redox cycling in vivo.

Demographics, clinical features and laboratory findings were evaluated.

Serum alanine aminotransferase ALTtotal bilirubin TBilblood urea nitrogen BUNcreatinine Crand arterial blood lactate Lac and partial pressure of oxygen PaO 2 during different time periods itoxicacion day 3, 7, and 9 of treatment were observed in both groups, and ulceration of oral mucosa, pulmonary fibrosis, multiple organ dysfunction syndrome MODSand mortality were compared between the two groups.

Envenenamiento de Chelydra serpentina Reptilia: Efectos del herbicida Paraquat sobre el zooplancton Effects of Paraquat herbicide on zooplankton.


Welker K, Thompson TM. The overall survival rate was only The severity of clinical manifestations between the two groups were analyzed with Student’s t test or Fisher’s exact test. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later.

Here, we test the effects of paraquat on the expression of detoxification and antioxidant-related genes, as well as on the dynamics of pathogen titers. To further study the molecular mechanism underlying pir resistance in goosegrass, we performed transcriptome analysis of susceptible and resistant biotypes of goosegrass with or without paraquat treatment.


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 one of the most widely used non-selective herbicides, especially in developing countries.

For all sampling methods, information gathering should include the use of a questionnaire to collect general information on the participants and on potential local sources of exposure, as well as the collection of biological samples. Paraquat use among farmers in Korea after the ban. Further studies demonstrated that Wld S markedly attenuated mitochondrial injury lor disruption of mitochondrial membrane potential, structural ihtoxicacion and decline of ATP induced by paraquat.

Chest radiographic findings in acute paraquat poisoning.

Also the factors that affect outcome were analyzed by logistic regression analysis. In addition, endonuclease IV could be induced by merely growing the mutant in pure O 2. Addition of immunosuppressive treatment to hemoperfusion is associated with improved survival after paraquat poisoning: Full Text Available El plomo Pb es un contaminante ambiental que causa efectos adversos a la salud humana. External and internal exposures were quantified and determinants of exposure identified by measurements, observations, and interviews.

Literatuuronderzoek naar de bepalingsmetboden an paraquat en diquat in groenten, fruit en andere plantaardige produkten. Most of the paraquat was confined to regions outside the blood-brain barrier and to brain regions that lack a complete blood-brain barrier e. Towards rapid diagnosis and therapeutic treatment of acute paraquat poisoning in Vietnam.

Bromadiolona – Wikipedia, la enciclopedia libre

The analytical method was compared with the liquid scintillation counting LSC method using 14C- paraquat. When ingestion occurs by humans and animals either accidentally, intentionally or maliciously, paraquat selectively accumulates in the lungs resulting in the production of oxygen-free radicals, causing membrane damage and cell death.


Paraquat affects mitochondrial bioenergetics, dopamine system expression, and locomotor activity in zebrafish Danio rerio. Oxidative stress and inflammation are involved in paraquat -induced cytotoxicity.

Imperial Chemical Industries plc, Cheshire England. Thirty maize grains were harvested from 6 ears for evaluation of grain moisture and grain dry matter weight. This previously unrecognized difference between E. Effect of low doses of herbicide paraquat on antioxidant defense in Drosophila.

The factors predicting paraquat exposures among pregnant women and neonates included working outside, living near farmland, having family members who work on a farm, drinking well water and using herbicides or paraquat.

To explore the relationship between pesticide exposure and dopaminergic toxicity, we developed a custom-tailored mathematical model of dopamine metabolism and utilize Paraquat is a salt widely used as a herbicide. In conclusion, silymarin attenuated paraquat -induced cytotoxicity in macrophage by inhibiting oxidative stress, NLRP3 inflammasome activation, cytokines secretion and apoptosis. An overview of the research on paraquat intoxication was presented alongside the information related to several bibliometric indicators, such as research trends, countries with their h-index, collaboration, hot issues, top-cited publications, journals, and institutions.

Ingestion of pesticides mainly paraquat accounted for one-fifth of suicides in South Korea in Quantitative analysis indicated a decrease in starch accompanying increases in fatty acids, monoterpenes, and resin acids. Heat shock proteins were either increased or unchanged upon paraquat -treatment suggesting that chaperone-mediated autophagy is not hampered by the agrichemicals. Topics include clinical and pathological findings, biochemical mechanisms, effects of oxygen, pulmonary effects of exposure, and effects on freshwater and marine organisms.

Paraquat dichloride is 1,1′-dimethyl-4,4′-bipyridylium dichloride.
