This current study addresses the effect of diazinon on reversible kinetic parameters such as Michaelis-Menten constant (KS) and Vmax of bovine retinal acetylcholinesterase (AChE). The Ks for the hydrolysis of acetylthiocholine iodide by AChE was increased while Vmax was decreased than the control value in the presence of the diazinon. A LineweaverBurk plot, Dixon plot and their secondary replot...

Dissipation kinetics of pesticides belonging to three chemical groups (linuron, diazinon and myclobutanil) was studied in an unamended agricultural soil and in this soil amended with three organic residues: sewage sludge (SS), grape marc (GM) and spent mushroom substrate (SMS). The soils were incubated with the residues outdoors for one and 12 months. Mineralized, extracted and non-extractable ...

Diazinon (O,0-diethyl·0-(2-isopropyl"6.methyl-4-primidinyl) phosphorothioate) is widely used to control turfarass insect pests. Poor control of soil-inhabiting insects has been found where diazinon has been applied to thatched turfgrass stands. The purpose of this study was to evaluate the environmental fate of diazlnon applied to turfgrass stands. A microecosystem was used to follow the fate o...

The present study aims to investigate the ameliorative role of an aqueous powders mixture of cinnamon and ginger tea against the insecticide diazinon-induced hepatotoxicity in adult male Sprague-Dawley white rats. The oral LD50 of diazinon “850.12 mg/kg body weight rat” was determined during the current investigation. The light microscope examination of the liver sections of the rats orally-tre...

The levels of resistance to two organophosphate acaricides, coumaphos and diazinon, in several Mexican strains of Boophilus microplus (Canestrini) were evaluated using the FAO larval packet test. Regression analysis of LC50 data revealed a significant cross-resistance pattern between those two acaricides. Metabolic mechanisms of resistance were investigated with synergist bioassays. Piperonyl b...

The oldest method for the managing of the illness is the use of medicinal plants. The use of herbal products as the first choice in self-treatment of minor conditions continues to expand rapidly across Iran. This makes the safety of herbal products an important public health issue. Pesticides are used widely in agriculture to increase the production by controlling the harmful insects and diseas...

The present study aimed to elucidate the structural changes in testis and epididymis of adult rats following subchronic peroral administration of cadmium at 30 mg/L, diazinon at 40 mg/L, cadmium at 30 mg/L, and diazinon at 40 mg/L, respectively. At the end of 90-day experiment, the samples of the testes and epididymis were assayed by qualitative and quantitative histological methods. The testis...

Following mutagenesis with ethyl methanesulfonate, selection in a susceptible strain with a concentration of the insecticide diazinon (0.0004%, w/v) above that required to kill 100% of the susceptible strain, the LC100 of that strain, resulted in a single gene response. The resultant four mutant resistant strains have equivalent physiological, genetical and biochemical profiles to a diazinon-re...

in the present study, the toxic effects on the embryos and larvae of the turbot were used as a model to investigate the diazinon, which contaminates aquatic ecosystems. the number of dead embryos significantly increased in response to diazinon concentrations 0.2, 0.4, 0.8, 1.6, 3.2, and 7.4 mg/l. the 48h lc50 value of diazinon for turbot embryos was estimated at 1.85 mg/l. dose–response decrea...
