Fig 1. ±PZQ causes relaxation of precontracted mesenteric arteries.

Fig 1

(A) Changes in tension measured in mouse mesenteric artery vessel strips evoked by KPSS (left, arrow), ±PZQ (circle, 100μM) added at basal tone (middle) and KPSS (arrow) followed by addition of ±PZQ to a contracted vessel (purple circle and trace, right). Solution exchanges to physiological saline shown as ‘w’ (wash). (B) Dose-response relationship quantifying peak relaxation evoked by indicated concentrations of ±PZQ. (C) Effect of repeated additions of ±PZQ (10μM, black circles) without solution exchange on contractile tone in a vessel contracted by solution exchange to KPSS (arrow).
