A study of occupational exposure to paraquat was performed among 11 knapsack spray operators at banana plantations in Costa Rica.

External and internal exposures were quantified and determinants of exposure identified by measurements, observations, and interviews. The median ages were 31 years [ Escherichia coli B and K are equally susceptible to the bacteriostatic effects of aerobic paraquatbut they differed strikingly when the lethality of paraquat was evaluated. Paraquat use among farmers in Korea after the ban. The aim of this current study is to explore the protective effect and potential mechanism of silymarin in paraquat -induced poe injury.

CiteScore measures average citations received per document published. A dopamine receptor contributes to paraquat -induced neurotoxicity in Drosophila. Ingestion of pesticides mainly paraquat accounted for one-fifth of suicides in South Korea in We also present a brief review of the literature, as well as a discussion of the therapeutic algorithm for severe paraquat poisoning. The influence of colonization of the pea Pisum sativum L.

Compensatory role of the Nrf2—ARE pathway against paraquat toxicity: This is a report of a case of recovery from confirmed paraquat poisoning in a clinical setting. On HRCT, pulmonary hemorrhage and edema appeared as diffuse air-space consolidation and pulmonary fibrosis as linear or band-like opacities.

Finding of CT and clinical in paraquat poisoning pulmonary injury. Relative changes in creatinine and CysC were monitored in serial blood and urine samples, and influences of non-renal factors were also studied. Melatonin proved its protective role when given before and after paraquat intoxication more than its detoxifying effect when given only after paraquat.

Enhanced microbial degradation implicated in rapid loss of chlorpyrifos from the controlled release formulation susucon R Blue in soil.

Inroxicacion dichloride is 1,1′-dimethyl-4,4′-bipyridylium dichloride. The average recovery rates of PQ were within a range of Ulinastatin can effectively inhibit this stress as well as cell apoptosis, thereby exerting a neuroprotective effect.

Transcriptome profiling to discover putative genes associated with paraquat resistance in goosegrass Eleusine indica L. The absolute reduction in the number of suicides was greatest among men, the elderly and in rural areas.

Topics include clinical and pathological findings, biochemical mechanisms, effects of oxygen, pulmonary effects of exposure, and effects on freshwater and marine organisms. Paraquat is a herbicide of great toxicological importance because it is associated with high mortality rates, mainly due to respiratory failure. Intoxicavion initially damages cochlear support cells leading to anoikis-like hair cell death.


Therefore, we designed this nationwide large-scale population-based retrospective intoxocacion study to investigate the outcome of paraquat poisoning with hemoperfusion and the additional effects of IST combined with hemoperfusion. Paraquat is actively concentrated into the lung but the site of uptake remains undefined. Pretreatment with CoQ 10 also significantly reduced the number of apoptotic cells and DNA fragmentation.
