Our results show significant changes in the expression of several antioxidant-related and detoxification-related genes in the presence of paraquatas well as an increase of pathogens titers.

To evaluate whether the early pulmonary irradiation can prevent or decrease the pulmonary damage and contribute to improve ultimate survival in paraquat lung. Based upon this evidence for mitochondrial dysfunction, transcriptional responses of oxidative stress- and intoxicaciob genes were measured. Few studies have addressed brain damage after paraquat poisoning.

Are you a health professional able to prescribe or dispense drugs? The absolute reduction in the number of suicides was greatest among men, the elderly and in rural areas.

There are no dermal toxicity studies suitable for evaluation of systemic lung effects in the toxicity database for paraquat A facile intoxicaicon “turn-off” method for sensing paraquat based on pyranine- paraquat interaction. After paraquat poisoning, the blood is in a hypercoagulable state and prolonged bed rest may increase the risk of thrombosis.

Topics include clinical and pathological findings, biochemical oaraquat, effects of oxygen, pulmonary effects of exposure, and effects on freshwater and marine organisms.

Alternative treatments are discussed. The routine treatment group had significantly lower arterial blood PaO 2 than the TCM group, while the TCM group had significantly lower incidence rates of ulceration of oral mucosa, pulmonary fibrosis, and MODS and a significantly lower mortality rate than the routine treatment group P treatment of patients with acute paraquat poisoning, compound monoammonium glycyrrhizinate combined with dandelion can effectively improve organ function, reduce the incidence of pulmonary fibrosis and MODS, improve the healing rate of oral ulcer, improve prognosis, and reduce mortality rate.


O peso de 1. 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. A cells and lung isolated mitochondria were divided int A Multicenter Retrospective Study. Paraquat PQ is a dopaminergic neurotoxin and a well-known pneumotoxicant that exerts its toxic effect via oxidative stress-mediated cellular injuries.

Paraquat is a herbicide widely used in agriculture. The magnetic activated carbon MAC was prepared, characterized and compared with powdered activated carbon PAC for its adsorptive parameters. The preparation and physico-chemical characterization of the nanoparticles was followed by evaluation of zeta potential, pH, size and polydispersion.

Increases of 3-fold or more were also seen with plumbagin, menadione, and phenazine methosulfate. The average recovery rates of PQ were within a range of Tendencias de mortalidad por traumatismos y envenenamientos en adolescentes: The chest CT image of lung injury in 6 cases of paraquat poisoning were analyzed retrospectively.

Severe paraquat poisoning: clinical and radiological findings in a survivor

Fewer cells in the hippocampus were concentrated and nucleoli had disappeared in the ulinastatin group. The mortality rate was Pesticide suicide mortality halved from 5. The objective of this work was to evaluate their effectiveness as desiccants applied before corn harvesting.


We included all patients admitted to a tertiary general hospital in Taiwan between and following a suicide attempt by paraquat self-administration. A total of 13, unigenes with 1, enzyme commission numbers were assigned to predicted KEGG metabolic pathways, and 12, unigenes were categorized into 25 KOG classifications. The distribution of [14C] paraquat was measured in selective brain regions using quantitative autoradiography in all three ;araquat groups of rats, 30 min and 24 h following dosing.

In all, 79 pregnant women were recruited from three hospitals located in agricultural areas in Thailand. We conclude that S-carboxymethylcysteine is a reliable alternative in managing patients with paraquat poisoning.

P Q in included in the p-tert butylcalix a rene cavity, a situation favoured by its pinched conformation paraquuat polar solvent while it is partially included in the p-tert butylcalix a rene cavity because of its in-out cone conformation. The rabbits were sacrificed intoxicaion, 10, and 14 days after injection of various amount of paraquatand then the lungs were isolated for HRCT and pathologic studies.

The regulation of paraquat in South Korea in was associated with a reduction in pesticide suicide. Directed-spray application of paraquat and diuron in pwraquat nut plants.
