Comparative Measurement of Serum Acetyl Cholinesterase Enzyme Using Three Different Methods
Introduction: IAChE (acetylcholinesterase) is one of the plasma’s enzymes that plays a crucial role in nervous signal transduction in synapses and is responsible for the hydrolysis of Ach. Material & Method: We investigated three methods for the determination of AChE in human blood serum, using three different assays. Michel methods are based on the measurement of hydrogen ion produced in pro...

متن کاملDetermination of serum cholinesterase activity and dibucaine numbers by an amperometric choline sensor.
Serum cholinesterase activity and the dibucaine numbers have been determined by using a hydrogen peroxide electrode and the enzyme choline oxidase immobilized on a nylon net. The analysis procedure is extremely simple and very fast allowing 30 cholinesterase determinations per hour. Both cholinesterase activity and dibucaine number measurements could be performed in 5 min and by using serum sam...

Introduction & Objective: Diazinon (DZN) is an organophosphate insecticide that one of the mechanisms of toxicity is the inhibition of cholinesterase. The aim of the present study was to evaluate the effects of diazinon on cholinesterase activity in blood serum and erythrocytes of male and female rats and to assess the protective role of vitamin E. Materials & Methods: In this experimental stud...
