In contrast, expression of GSTA was significantly greater in differentiated relative to undifferentiated cells after paraquat treatment. The conventional treatment group received routine gastric lavage with water. 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 intoxiicacion turn helped nutrient assimilation.

Deliberate self-poisoning with paraquat continues to be a intoxjcacion public health concern in many developing countries. Toxicological responses on cytochrome P and metabolic transferases in liver of goldfish Carassius auratus exposed to lead and paraquat.

Severe paraquat poisoning: clinical and radiological findings in a survivor

Moreover, we tested the effects of pollen as mitigating factor to paraquat exposure. Response linearity, repeatability, accuracy and detection limit were also evaluated.

We observed that paraquat -induced oxidative stress in differentiated SHSY-5Y cells as indicated by an increase in the production of cellular reactive oxygen species ROS. Selenium is a cofactor for glutathione peroxidase GPxwhich is one of the major endogenous antioxidant enzymes.

De resultaten van de literatuurstudie worden samengevat in een overzicht van de bepalingsmetboden van paraquat en diquat in groenten en fruit e.


In the present studies we compared paraquat redox cycling in primary cultures of undifferentiated and differentiated mouse keratinocytes and determined if this was associated with oxidative stress and altered expression of antioxidant enzymes. These data demonstrate that paraquat induces oxidative stress in keratinocytes leading to increased expression of antioxidant genes. Gramoxnoe is difficult to find out the effect of pulmonary irradiation on the course of the paraquat lung because the precise plasma and urine paraquat concentration were not available porr control and irradiation groups.

MAC an iron oxide and PAC composite was removed from slurry through magnet thus no cake formation and secondary problems observed for PAC was not encountered. The pulmonary toxicity of paraquat resembles in several ways the toxicity of several other lung toxins, including oxygen, nitrofurantoin and bleomycin. Numerous studies have proved that the concentration of serum PQ plays an important role in prognosis.

The pretreatment of curcumin significantly decreased gene expression and protein production of amyloid precursor protein. Pulmonary irradiation was started within 24 hours after admission from day 1 to day 11 after ingestion of paraquat.

The estimates of toxicokinetic parameters for the apparent clearance, the apparent volume of distribution and elimination half-life were 1. To explore the effect of sucralfate on cytokines in rats with paraquat PQ poisoning. No single cause has been identified for these dramatic losses, but rather multiple interacting factors are likely responsible such as pesticides, malnutrition, habitat loss, and pathogens.

Comparison with the reference method showed that the electrochemical pro provides superior results in quantification of analytes.

Paraquat – Wikipedia, a enciclopedia libre

We report 35 patients with mild to severe paraquat poisoning, which beside standard supportive treatment received mg S-carboxymethylcysteine, up to w. They can disturb the normal catalytic activities of many enzymes by means of different toxicity mechanism. Paraquat intoxication and associated pathological findings in three dogs in South Africa.


Edaravone, an antioxidant and radical scavenger, showed protective effects against oxidative stress-like condition. Paraquat bis hexafluorophosphate undergoes stepwise dissociation in acetone. Goosegrass Eleusine indica L.

Fewer cells in the hippocampus were concentrated and nucleoli had disappeared intoxicacino the ulinastatin group. Therefore, it is necessary to study to degrade paraquat compounds by photolysis method with using ZnO.

We included all patients admitted to a tertiary general hospital in Taiwan between and following a suicide attempt by paraquat self-administration. In this cross sectional study, medical records of all paraquat intoxicated patients were reviewed at Taleghani hospital of Urmia, Iran, from to Paraquat -induced pulmonary toxicity, therefore, is a potentially useful model for evaluation of oxidant mechanisms of toxicity.

The subjects were interviewed about personal characteristics, agricultural activities and pesticide use patterns. The sensitivity of the method, expressed as detection limits, was as low as 3. Chronic low dose paraquat treatment had a very different pattern of effects that were also dependent upon the age of the animal: Thus, colonization by methylobacteria considerably increased the adaptive protection of pea plants to the paraquat -induced oxidative stress.

The adsorption isotherm was found to correspond with Langmuir Isotherm and the maximum paraquat adsorption is
