It is shown from the kinetics of inhibition of cholinesterase by N-methylcarbamates and organo-phosphates that the LD50 dose is likely to be a much greater multiple of the dose causing signs of poisoning in 50%-of the animals (the ED50) for the carbamates than for the organophosphates. The expected difference was demonstrated by a comparison of the LD50s and ED50s, intravenous and intramuscular...

background: cardiac toxicity is one of the life-threatening effects of severe organophosphate (op) poisoning. we presented a patient with severe op poisoning, in cardiovascular shock poorly responsive to conventional treatments, who could be resuscitated successfully with intravenous lipid emulsion (ile) therapy. case report: a 26-year-old female was admitted to our emergency department who had...

The aim of this review is to provide an update on the current use of cyclodextrins against organophosphorus compound intoxications. Organophosphorus pesticides and nerve agents play a determinant role in the inhibition of cholinesterases. The cyclic structure of cyclodextrins and their toroidal shape are perfectly suitable to design new chemical scavengers able to trap and hydrolyze the organop...

The sixty-seven papers in this book are grouped under the following chapters: Esterase Structures, Catalytic Properties of Cholinesterases, Catalytic Properties of Paraoxonases and Related Esterases, Biology of Cholinesterases, Biology of Paraoxonases and Related Esterases, Toxicity and Degradation of Organophosphorus Compounds, Neuropathy Target Esterase, and Miscellaneous. The chapters are pr...
