Effects of magnesium chloride on in vitro cholinesterase and ATP ase poisoning by organophosphate (chlorpyrifos)

The present study investigated possible benefits of magnesium ion (as MgCl 2 ) in organophosphorus poisoning targeting its ability to interact with substrates and membrane enzymes. Blood samples collected from volunteered healthy adult by venepuncture into anticoagulant test tubes containing EDTA were separated into plasma and red blood cell and divided into three groups namely: normal, pesticide only (0.25‐2.0 mmol/L chlorpyrifos) and pesticide (0.25‐2.0 mmol/L chlorpyrifos) + 0.1 mol/L MgCl 2 . Acetylcholinesterase, Na + /K + ATP ase and Ca 2+ ATP ase activities were evaluated. Results showed that Chlorpyrifos significantly ( P
