The changes of N-methyl-D-aspartate (NMDA) receptor and protective efficacy of memantine (MEM) in rats poisoned with dichlorvos were studied. Dichlorvos evoked down-regulation of the affinity and density of [(3)H]MK-801 binding to NMDA receptor in the brain of rats receiving dichlorvos (15 and 25 mg/kg bw, i.p.). The binding capacity of NMDA receptor and acetylcholinesterase activity were deter...

background: the present study was the first attempt for determination and measurement of pesticide residues in tomatoes used in salad production plants in isfahan, central iran. methods: a multiresidue method based on modified quechers (quick, easy, cheap, effective, rugged and safe) sample preparation, followed by gas chromatography mass spectrometry (gc–ms) was developed and validated for the...

The aim of the study was to determine the effects of taurine in rats exposed to subacute dichlorvos toxicity. Fifty rats were weighed and assigned into five groups of ten rats each. The groups received: distilled water, soya oil (1 ml/kg), taurine (50 mg/kg), dichlorvos (10 mg/kg) and the combination treatment group received taurine first and then dichlorvos 30 min later. The treatments were ad...

tage-dependent dichlorvos and propoxur tolerance in a field population of the German cockroach, Blattella germanica Linnaeus (Blatodea: Blattellidae), was investigated in the laboratory using a topical application bioassay. The results showed the 6 week-old nymphs were more tolerant to dichlorvos and propoxur than the other ages tested. LD₅₀ values of dichlorvos and propoxur for the 6 week-old ...

Pollution of Lake Bosomtwe is a major concern in Ghana due to its derived socio-economic benefits such as employment, ecotourism and protein source the people basin. Besides these benefits, lake water used for domestic purposes has since served drinking people. However, use agrochemicals within basin intensified last decade. The problems associated with fertilizer pesticide seem carry it higher...

Assessment of chemical exposures in the marine environment is frequently undertaken sedentary organisms inhabiting coastal environments. However, predatory pelagic fish should be considered sentinel species, as they play an important role sustainability ecosystems due to their high position trophic webs. In this study, carboxylesterase (CE) activities were analysed four tuna species commercial ...

Objective: Aim of this study was to evaluate the effect of Zingiber officinale in mitigating oxidative damage and reproductive toxicity in the testis, induced by chronic dichlorvos administration in male Wistar rats. Methods: Twenty-four adult male Wistar rats were divided into 4 groups of 6 rats in each group. Group I received olive oil (1 ml/kg bwt/day) and served as control group, while Grou...

The indiscriminate use of pesticide is a treat to non-target organisms. This study evaluates the haematological and biochemical changes induced by inhalation of local Nigerian dichlorvos insecticide on rats. The rats were randomly assigned to a control group which received only food and water and a test group which, in addition to food and water, was exposed to the pesticide for a period of 4 h...

Background: Pesticide use for fruits and vegetable production in Uganda may result presence of residues on produce which pose health risks to consumers. This research aimed at conducting a risk assessment pesticide vegetables Kampala Metropolitan Area, Uganda. Method: Pesticides were measured 160 samples analysed using liquid chromatography-tandem mass spectrometry. Fruit consumption informatio...
