An ion-sensitive microelectrode study on the effect of a high concentration of ivermectin on chloride balance in the somatic muscle bag cells of Ascaris suum
Published online by Cambridge University Press: 06 April 2009
Summary
Ivermectin has been shown to increase chloride conductances of invertebrate cells. On the muscle cells of the parasitic nematode Ascaris, ivermectin acts as both a GABA receptor antagonist and a chloride channel opener. In this study, ion-sensitive microelectrodes were used to investigate the effect of ivermectin on intracellular C1− concentration of the somatic muscle bag cells of Ascaris suum. Incubation of muscle cells with ivermectin (10 μM in 1% dimethyl sulphoxide vehicle for 60 min) increased intracellular C1− by 2·9 mM or 15% compared to controls (P > 0·01, n = 6).
