21. Myasthenia is treated with immunosuppressants, cholinesterase inhibitors and, in selected cases, thymectomy. 22. In 1958 Skou went to a conference in Vienna to describe his work on cholinesterase . 23. The two types of cholinesterase are acetylcholinesterase ( ACHE ) and butyrylcholinesterase ( BCHE ). 24. A cholinesterase inhibitor ( or " anticholinesterase " ) suppresses the action of the enzyme. 25. As with other organophosphates, temephos affects the central nervous system through inhibition of cholinesterase . 26. The major route of metabolism is by its target enzymes via cholinesterase -mediated hydrolysis. 27. It will be tested for cholinesterase . 28. It is unclear if the medication donepezil, a cholinesterase inhibitor, reduces delirium following surgery. 29. However, unlike other non-depolarizing neuromuscular blockers, it is metabolized by plasma cholinesterase . 30. Similarly, cholinesterase reactivators antidotes such as 2-PAM were tested on about 750 subjects.
