Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmacology and Toxicology Candidate: Natália Kuzmiaková Supervisor: PharmDr. Marie Vopršalová, CSc . Consultant: mjr. PharmDr. Vendula Hepnarová, Ph.D. Title of diploma thesis: In vivo evaluation of the efficacy of the novel reactivator against tabun. This study tackles the problem of irreversible inhibition of acetylcholinesterase (AChE). This enzyme degrades neurotransmitter acetylcholine (ACh), wich ensures transmisson of nerve impulses in central nervous system and in periphery. Organophospates (OP) are substances that cause irreversible blocade of AChE and that susubsequently leads to accumulation of AChE in synapses and inducing of muscarinic and nicotinic effects for life threatening condition. Oximic nature reactivators shown to this day the gratest potencial in inhibiting OP bond with AChE. Because reactivation abilities of to date synthesided oxime are not sufficient, new reactivators are being researched. The doal of my work was to test the potencial to reactivate AChe one of them (precisely oxime K 870). The method i used was colorimetric Ellman method modified by Bajgar, where the activity of AChE after reactivation was measured by absorbance in brain, diaphragm and blood of modeled orgamisms. The...
