Objective: Paraquat (PQ) is a herbicide which induces oxidative stress and inflammation. Anti-inflammatory and anti-oxidant effects were shown for Zataria multiflora (Z. multiflora) and carvacrol previously. The effects of Z. multiflora hydroalcoholic extract and carvacrol on systemic inflammation and oxidative stressinduced by inhaled PQ were examine...
bachground: paraquat (pq) intoxication manifests with pulmonary edema and fibrosis, heart failure, hepatic failure, and sometimes convulsions. in severe cases, the patients may die within the early hours. at best conditions, the conventional therapeutic methods can only save less than 50% of the victims of intentional pq intoxication. the aim of this study was to evaluate the outcome of new the...
Background: Paraquat (PQ) is one of the most important herbicides used in agriculture. Objectives: This study was conducted to compare preventive effect vitamin D (Vit D) and N-acetylcysteine (NAC) against kidney injury rats versus promotive PQ. Methods: In this study, were divided into six groups. The control group (group 1) received normal saline, Vit 2) intraperitoneal (IP) injections of+Vit...
The herbicide paraquat (PQ) has increasingly been reported in epidemiological studies to enhance the risk of developing Parkinson's disease (PD). Furthermore, case-control studies report that individuals with genetic variants in the dopamine transporter (DAT, SLC6A) have a higher PD risk when exposed to PQ. However, it remains a topic of debate whether PQ can enter dopamine (DA) neurons through...
Paraquat dichloride (N,N-dimethyl-4-4'-bipiridinium, PQ) is an extremely toxic chemical that is widely used in herbicides. PQ generates reactive oxygen species (ROS) and causes multiple organ failure. In particular, PQ has been reported to be an immunotoxic agrochemical compound. PQ was shown to decrease the number of macrophages in rats and suppress monocyte phagocytic activity in mice. Howeve...
The mortality rate of acute paraquat (PQ) poisoning depends on the PQ concentration in the blood. It has been shown that the kidneys eliminate PQ effectively. However, early renal function deterioration is frequently observed in acute PQ intoxication. This study is designed to compare the efficacy of PQ elimination with hemoperfusion (HP) and kidneys, taking into account the functional deterior...
Acute paraquat (PQ) toxicity induces redox cycling leading to fatality in both man and animals with clinical management being supportive therapy due lack of specific effective antidote. This study thus aimed at determining the sero-biochemical pathological changes induced by acute PQ administration male rats mitigating role sodium selenite. Forty were used for grouped into 5 eight viz: Group I ...
Paraquat (PQ) is one of the most widely used herbicides in the world, which has a good occupational safety record when used properly. While, it presents high mortality index after intentional exposure. Accidental deaths and suicides from PQ ingestion are relatively common in developing countries with an estimated 300,000 deaths occurring in the Asia-Pacific region alone each year, and there are...
BACKGROUND The present study was designed to analyze the dynamic changes in transforming growth factor beta 1 (TGF-β1), interleukin (IL)-10, and tumor necrosis factor alpha (TNF-α) in paraquat (PQ)-intoxicated rats and to evaluate the effects of artesunate on PQ-induced lung injury. METHODS Sixty healthy male Sprague-Dawley (SD) rats were randomly assigned to the control (n = 10), PQ (n = 25)...
A Bacillus subtilis sigM null mutant, lacking the extracytoplasmic function sigma(M) protein, was sensitive to paraquat (PQ), a superoxide-generating reagent, but not to the redox stress-inducing compounds hydrogen peroxide, cumene hydroperoxide, t-butyl hydroperoxide, or diamide. Surprisingly, a sigM mutant was only sensitive to superoxide-generating compounds with a dipyridyl ring such as PQ,...
