Investigates the effects of two well-known carbamate~, physostigmine and pyridostiginine against organophosphorous compound and nerve gas toxicity. Physostigmine pretreatment for 30 min enhanced the survival time of rats against DFP intoxication whereas it did not have any effect with sarin poisoning. However, pyridostigmine pretreatment did not produce any significant effect on survival time e...

A comprehensive multi-residue method for the chromatographic separation and accurate mass identification of 101 pesticides and their degradation products using liquid chromatography/time-of-flight mass spectrometry (LC/TOF-MS) is reported here. Several classes of compounds belonging to different chemical families (triazines, organophosphorous, carbamates, phenylureas, neonicotinoids, etc.) were...

The chemical compound temephos (0,0,0',0'-tetrametyl-0,0'-thiodi-p-phenylene phosphorothioate) is an organophosphorous pesticide that has been used in Brazil since 1967 in control campaigns against the mosquito Aedes aegypti, the vector of dengue and yellow fever. We used single cell gel electrophoresis (SCGE), SOS/umu and Ames/Salmonella assays to test the toxicity and mutagenicity of temephos...

This study was designed to investigate the acute toxic effect of Diazinon on some blood parameters. Twelve male rabbits were divided randomly and equally into two groups, A treated group (T) control (C). Animals dipped in 3:1000 diazinon solution. Within 24 hours following treatment, animals showed moderate symptom organophosphorous poisoning such as dyspnia depression. Blood analysis revealed ...
