Exposure to paraquat leads to acute lung injury and oxidative stress is widely accepted as a contributor to paraquat-induced acute lung injury. Recent studies have reported that consumption of water with dissolved molecular hydrogen to a saturated level (hydrogen water) prevents oxidative stress-induced diseases. Here, we investigated whether consumption of saturated hydrogen saline protects ra...

In this study, we measured the effects of different concentrations of paraquat (0,01 mM and 1,0 mM) on the 1-14CO2 and 6-14CO2 production of rabbit lung slices and isolated alveolar macrophages, in 20% and 95% oxygen phases respectively. A 95% oxygen phase induced an increase in the 6-14C-glucose oxidation of contorol lung slices over a 3-hour period, while the increased activity of the pentose...

INTRODUCTION Paraquat is a quaternary nitrogen herbicide which is highly toxic to human. Death is usually from respiratory failure and may occur within days up to a month after exposure. It is easily available and commonly abused to commit suicide. METHODOLOGY This is a retrospective study describing the demographic characteristics, clinical features and outcomes of paraquat poisoning cases a...

Paraquat poisoning is very severe. Most victims, including those who have ingested a small amount, will die from Paraquat poisoning. The cause of death in the majority of such cases is lung fibrosis. Paraquat poisoning in patients with positive human immunodeficiency virus (HIV) infection status has seldom been reported. Herein, we report a case of an HIV patient with Paraquat poisoning who had...

Paraquat, a quaternary ammonium bipyridyl herbicide, produces degenerative lesions in the lung after systemic administration to man and animals. The pulmonary toxicity of paraquat resembles in several ways the toxicity of several other lung toxins, including oxygen, nitrofurantoin and bleomycin. Although a definitive mechanism of toxicity of paraquat has not been delineated, a cyclic single ele...

The enhancing effect of sodium chloride addition on the adsorption of paraquat onto activated carbon was discussed from the standpoints of equilibrium amount adsorbed and adsorption rate in vitro. The amount of paraquat adsorbed was increased by the addition of sodium chloride. The amount adsorbed with 0.1% addition was about five times greater than that in sodium chloride-free solution at an e...

SNCA and MAPT genes and environmental factors are important risk factors of Parkinson's disease [PD], the second-most common neurodegenerative disease. The agrichemicals maneb and paraquat selectively target dopaminergic neurons, leading to parkinsonism, through ill-defined mechanisms. In the current studies we have analyzed the ability of maneb and paraquat, separately and together, to induce ...

Background Paraquat is a broad spectrum herbicide used particularly in burndown, pre-plant of row crops and the pre-harvest desiccation some crops. In Brazil, paraquat was re-evaluated by Anvisa, leading to prohibition production sales on September 22, 2020, until July 31, 2021. Objective The objective this review characterize use Brazil describe status other countries, agronomic implications i...
