Atorvastatin protected from paraquat -induced cytotoxicity in alveolar macrophages via down-regulation of TLR In this study, we found that triptolide TPLa Chinese medicine extract, exerts an anti-lung fibrosis effect by inhibiting the EMT of lung epithelial cells.

In all, 79 pregnant women were recruited from three hospitals located in agricultural areas in Thailand.

Bromadiolona – Wikipedia, la enciclopedia libre

In contrast to the adult and elderly rats where paraquat levels fell over the 24 h post-dosing period to negligible levels, paraquat concentrations in neonatal brains did not decrease with time between 0. Psychiatric comorbidity and its impact on mortality in patients who attempted suicide by paraquat poisoning during In South Korea, paraquat prohibition led to a lower rate of suicide by paraquat poisoning, as well as a reduction in the overall suicide rate.

Ulinastatin is a protease inhibitor that can effectively stabilize lysosomal membranes, prevent cell damage, and reduce the production of free radicals. The patients with paraquat poisoning who were admitted to our department in recent two years were observed to screen out the patients with large vessel raticidad. Paraquat administration in Drosophila for use in metabolic studies of oxidative stress.

This study essentially provides a readily accessible fluorescent system for PQ sensing which is cheap, robust, and technically simple, and it is envisaged to find more interesting clinical and environmental applications. PAC also caused blackening of pipes and flow meter.


In conclusion, French Guiana has the largest cohort of paraquat poisonings in the European Union. Among them, the best bound of the modified PSS score was 6. Directory of Open Access Journals Sweden. The snake was brought to the medical consult and identified as a Thamnodynastes cf. In intoxicacipn current studies we have analyzed the ability of maneb and paraquatseparately and together, to induce synucleinopathy and tauopathy in wild type mice. 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 ratkcidas and to guide the clinical treatment.

From a comparative viewpoint, lungs of nestling kestrels are less sensitive to paraquat than mammalian lungs. It may be useful to educate health professionals and the general population about the serious consequences raticiidas exposure to paraquat.

There was no evidence for the presence of significant amounts of other radioactive compounds in the tubers, even though chromatography of extracts of the desiccated plants showed that photochemical degradation products were formed on the leaves: The aim of this work is to optimize all factors that can influence this determination.

Full Text Available Since the most characteristic feature of paraquat poisoning is lung damage, a prospective controlled study was performed on excised rat lungs in order to estimate the intensity of lesion after different doses.

Poor, a possible direct chemical reactivity between PQ and NaSAL is also a putative pathway to be considered, this hypothesis being the ground of the present study. Paraquatplumbagin, menadione, and phenazine methosulfate are known to generate superoxide radical anions via redox cycling in vivo.


The estimated suicide rates during this period decreased by 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. Immunohistochemical findings showed that CHOP immunoreactivity was significantly lower in the ulinastatin group than in the paraquat group. Also the factors that affect outcome were analyzed by logistic regression analysis.


Recovery from paraquat poisoning in the dog is rare. Paraquat PQone of the most widely used herbicides, is extremely dangerous because it generates the highly toxic superoxide radical.

Se utilizaron fuentes secundarias. Rotenone and paraquat perturb dopamine metabolism: Clinical screening of paraquat in plasma samples using capillary electrophoresis with contactless conductivity detection: This study aimed to evaluate the reliability and value of spectrophotometry in detecting the concentration pod serum PQ.

envenenamiento por paraquat: Topics by

The pretreatment with silymarin could remarkably reduce the cytotoxicity, promote the expression of Trx and intocicacion enzymes, and suppress the TXNIP and NLRP3 inflammasome activation. The protective effect 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.

It has a therapeutic effect on acute lung injury as induced by paraquat. Efectos del herbicida Paraquat sobre el zooplancton Effects of Paraquat herbicide on zooplankton.

Silymarin can exert a potent antioxidative and anti-inflammatory effect in various pathophysiological processes.
