Experimental study of sucralfate intervention for paraquat poisoning in rats. Paraquat is a herbicide widely used in agriculture.

Paraquat poisoning is well known for causing multiple organ function failure MODS and high mortality. The majority of the farmers used preexisting paraquat Optical and electronic microscopes were used to examine pathological changes. Alternative treatments are discussed. In conclusion, silymarin attenuated paraquat -induced cytotoxicity in macrophage by inhibiting oxidative stress, NLRP3 inflammasome activation, cytokines secretion intoxicacon apoptosis.

There was one case of right common femoral vein thrombosis, one case of bilateral calf muscle vein thrombosis, and one case of right calf superficial vein thrombosis and right calf muscle vein thrombosis. Paraquat is a contact herbicide which is highly toxic to human.

The patient developed oliguric renal failure, deterioration of liver function, and acute respiratory distress syndrome over next few days. This is a report of a case of recovery from confirmed paraquat poisoning in a clinical setting.

On contrary, median TL values did not correlate with paraquat concentration irrespectively of the exposure protocol. The patient underwent intensive hemoperfusion for 2 h 3 times a day for 9 consecutive days and ;araquat continuous renal replacement therapy CRRT in the mode of continuous veno-venous hemofiltration CVVH for 10 consecutive days in addition to routine medications.


This difference in retention of paraquat between strains was demonstrated by delayed loss of viability, by growth inhibition, and by cyanide-resistant respiration after brief exposure to paraquatwashing, and testing in fresh medium. To describe the chest radiographic findings of acute paraquat poisoning.

A mixed solution of paraquat paraquaat was administered twice a week by lavage at a dose of 10 or 15 mg kg -1 bodyweight containing 30 or 45 mg kg -1 bodyweight maneb, respectively from day 6 after pregnancy till ablactation. In this study, we assessed the neuroprotective effect of curcumin against paraquat and explored the underlying mechanisms of curcumin in vitro. Paraquat is thus frequently used in the fruit fly Drosophila melanogaster and other animal models to study PD and the degeneration of dopaminergic neurons DNs that characterizes this disease.

To evaluate whether mitochondrial respiration was related to earlier hatch times, oxygen consumption rate parzquat measured in whole embryos. The median ages were 31 years [ The annual suicide rate in South Korea is the highest among the developed countries. Moreover, treatment of PQ strongly decreased the nuclear Nrf2 levels.

The patient was followed up for 6 months after discharge and no complaint of discomforts was reported. Recovery from paraquat poisoning in the dog is rare. In in vivo studies, TPL improves the survival state and inhibits lung fibrosis in mice. Paraquat intoxication and associated pathological findings in three dogs in South Africa. These data demonstrate that paraquat induces oxidative stress in keratinocytes leading to increased expression intoxixacion antioxidant genes.


Acute lung injury — a missed diagnosis Photolysis is a process of UV irradiation with a wavelength of nm. Then, the rats were administered normal saline, sodium bicarbonate solution, or sucralfate suspension as an intervention by gastric lavage. Imperial Chemical Industries plc, Cheshire England.

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. Differential pulse voltammetry VDP method for both compounds were validated.

Paraquat dichloride is 1,1′-dimethyl-4,4′-bipyridylium dichloride. We investigated the dependence of analytical performance of this method on the experimental conditions, such as the ion strength, medium pH, and so on.

Low-inspired oxygen therapy should be given until it becomes impractical in the face of hypoxemia. The gravid rats were randomly divided into three groups one control and two experimental groups.

Intoxicación por paraquat

This study aimed to evaluate the data on cases of acute paraquat poisoning and to compare different variables between survivors and non-survivors. Awareness of comorbid psychiatric illnesses, especially dysthymic disorder, is vital in the prevention and treatment of suicide by paraquat poisoning.

This was reflected in kinetic studies using lung and liver microsomes. Modified poisoning severity score for early prognostic evaluation in acute paraquat poisoning.
