Loading erythrocytes with Primaquine (PQ) is advantageous. However, PQ produces damage to erythrocytes through free radicals production. Statins have antioxidant action and are involved in protective effect against situation of oxidative stress. Thus the protective effect of pravastatin (PS) against PQ induced oxidative damage to human erythrocytes was investigated in the current studies upon l...

glutathione (gsh) is one of the most important antioxidants that plays an essential role in detoxification of reactive oxygen species (ros) which oxidizes to glutathione disulfide (gssg). paraquat (pq), awidely used herbicide, causes pulmonary injury with the productionof ros. excessive ros accumulation as a consequence of pq exposure are frequently targeted by gsh thereby oxidative stress lead...

Paraquat is a commonly used herbicide in many countries which can lead to systematic poisoning on exposure, In this study, paraquat (PQ)-induced changes in the expression of Cyclooxygenase-2 (COX-2) along with biochemical and histopathological changes in the lungs, liver and kidneys were studied. Twenty four male Wistar rats (180-200 g) were exposed either against saline as control group or var...

Paraquat (PQ) has been one of the most widely used herbicides in the world. PQ, when ingested, is toxic to humans and may cause acute respiratory distress syndrome. To investigate molecular perturbation in lung tissues caused by PQ, Sprague Dawley male rats were fed with PQ at a dose of 25 mg/kg body weight for 20 times in four weeks. The effects of PQ on cellular processes and biological pathw...

Experimental evidence suggested that sodium ferulate (SF) and oxymatrine (OMT) combination had synergistic anti-inflammatory and antioxidant effects. We hypothesized that SF and OMT combination treatment might have protective effects on paraquat-induced acute lung injury. In our study, the Swiss mice were randomly divided into seven groups, including control, paraquat (PQ), SF (6.2 mg/kg/day); ...

OBJECTIVE To evaluate the role of rapamycin (RAPA) in paraquat (PQ)-induced acute lung injury. METHODS Lung tissues were stained with HE and lung histology was observed. Mortality rate, and neutrophil and leukocyte count in blood and bronchoalveolar lavage fluid (BALF) were recorded. Protein content in BALF was determined by Coomassie blue staining. Malondialdehyde (MDA) content, glutathione ...

Background and purpose: Paraquat (PQ) is a bipyridinium herbicide that is very soluble in water. This non-selective contact herbicide is widely used in agriculture for weed control. In addition to the environmental impact, paraquat affects the entire body, especially the respiratory system, central nervous system and lymph nodes. In this study degradation of paraquat was investigated using Fent...

Background and purpose: Resveratrol (RSV) is a naturally existing polyphenolic compound abundantly found in grapes and several plants. It has potent free radical scavenger and antioxidative properties with significant effects in reducing oxidative damage. Oxidative stress and mitochondrial dysfunction contribute to PQ induced tissue damage. In this study, the protective effect of RSV was invest...

This cytogenetic and pharmacological study attempts to clarify genotoxicity-enhancement-effect of dl-α-tocopherol (one form of vitamin E) in combination with the herbicide 1,1'-dimetyl-4,4'-bipyridium dichloride (paraquat, PQ) on cultured anuran leukocytes using the superoxide dismutase-mimic Mn(III)tetrakis(1-methyl-4-pyridyl)porphyrin (Mn(III)TMpyP), the hydrogen peroxide-scavenger catalase a...

Microgrids are increasingly being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. However, the technical challenges associated with the operation and controls are immense. Management of dynamic power balances, power flow, and network voltage profiles imposes unique challenges in the context of microgrids. Stability of t...
