    The effect of HI-6 on cholinesterases and on the cholinergic system of the rat bladder

  • Original language description

    OBJECTIVES: The current standard treatment of organophosphate poisoning consists of an administration of anticholinergic drugs and cholinesterase reactivators (oximes). Oximes can react - except their reactivating effect on cholinesterases - directly with cholinoreceptors. HI-6 is an oxime that may have an inhibitory effect on the muscarinic receptors, too. METHODS: In our work, we have investigated an influence of HI-6 on the acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and on the muscarinic receptors in vitro. The study was conducted using biosensor technique and on the rat bladder using in vitro test (tissue bath; methacholine as muscarinic agonist). IC50 for BChE from human serum was determined to be 1.01x10-6 M and for human erythrocytes AChE 3.31x10-6 M, respectively. CONCLUSION: We assume that the demonstrated contractile response can be attributed to the inhibition of the AChE at the lower concentration and to a predominant inhibition of muscarinic receptor at high

    Působení látky HI-6 na cholinesterázy a krysí močový měchýř

  • Czech description

    Běžná léčba otrav organofosfáty spočívá v podání anticholinergik a reaktivátorů (oximů). Oximy mohou reagovat, mimo vlastních cholinesteráz, přímo s cholinergními receptory. HI-6 je oxim který může toto působení vykazovat také. V této práci byl zkoumán vliv reaktivátoru HI-6 an acetylcholinesterázu (AChE) a butyrylcholinesterázu (BChE) a in vitro na muskarinové receptory. Studie byla realizována za použití biosenzoru, respektive testování tkání. Byly stanoveny hodnoty IC50 pro BChE a AChE. Ve studii bylvysloven předpoklad inhibice AChE při nižších koncentracích reaktivátoru a inhibici muskarinových receptorů při vyšších koncentracích.
