Janus green B (JG-B) dye is used for vital staining of mitochondria and its reduction and oxidation shows the electron transfer chain alteration. The defect in electron transfer chain of mitochondria by paraquat is linked to free radical formation. In this present study we compared the abilities of different angiotensin-converting enzyme inhibitors, captopril (a thiol ACEi), enalapril, and lisi...

BACKGROUND Parkinson's disease (PD) is a progressive neurodegenerative condition that has genetic susceptibility, aging, and exposure to certain chemicals as risk factors. In recent decades, epidemiological and experimental studies have investigated the role of pesticides in the development of PD, in particular that of the herbicide paraquat. Here, we, therefore, aim to systematically review th...

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...

Background: Paraquat dichloride is a highly toxic herbicide which is still used in many developing countries. African cat fish (Clarias gariepinus) is a commercially important species in many countries and was selected assess accumulation and elimination of paraquat dichloride in its tissues. Methods: Groups of ten fish with equal lengths and weights were exposed to varying concentrations of...

Herbicide resistance is a challenge for modern agriculture further complicated by cases of resistance to multiple herbicides. Conyza bonariensis and Conyza canadensis are invasive weeds of field crops, orchards, and non-cropped areas in many parts of the world. In California, USA, Conyza populations resistant to the herbicides glyphosate and paraquat have recently been described. Although the m...

INTRODUCTION Paraquat is a widely used nitrogen-based herbicide which is lethal and causes multi-organ failure by accumulation in cells, which subsequently leads to death. CASE PRESENTATION The present case report introduced a 25-year-old male with nausea, vomiting, and severe substernal burning sensation after incidentally ingestion of a large amount of paraquat. The treatment of the patient...

Five patients are reported who developed evidence of acute lung damage after proved ingestion of paraquat. In two the lung changes resolved; in one an aspiration pneumonia occurred, which was successfully treated, while two developed fatal pulmonary oedema. These pulmonary complications after paraquat intoxication appear more common than the progressive pulmonary fibrosis previously described. ...

The treatment of flax cotyledons (Linium usitatissimum) with paraquat was shown to decrease the levels of chlorophyll and carotenoid pigments. The fatty acid content of chloroplast fragments isolated from treated tissue was determined and shown to be greatly decreased by paraquat treatment. The superoxide radical was demonstrated to play an important role in the phytotoxic action of paraquat by...

Paraquat poisoning is associated with very high mortality and often results in severe complications including pulmonary fibrosis and multi-organ failure. Majorities of the reported cases had paraquat exposure from oral route either due to accidental intake or suicidal attempt. Systemic complications from dermal exposure were infrequently reported. We reported a patient suffering from acute rena...

Paraquat toxicity occurs through the high production of reactive oxygen species (ROS) which cause damage due to oxidative stress. Antioxidants can reduce prevention Taurine has shown ability act as an antioxidant. The aim this research is find a effect antioxidant taurine decrease kidney caused by stress paraquat looking at histopathology changes. 25 male adult mices from strain DDY were used a...
