a Isometric contraction of Ascaris suum muscle strip produced by increasing concentrations of acetylcholine and inhibition of contractions induced by carvacrol. Short bar indicates the application of acetycholine (1, 3, 10, 30, and 100 μM), a full line the presence of carvacrol 100 μM, and a dashed line the presence of carvacrol 300 μM. b The concentration-response plot for acetylcholine showing mean±S.E. bars. Control (n=8); in the presence of 100 μM carvacrol (n=8); and in the presence of 300 μM carvacrol (n=8); after washing (n=8, dashed line)
