Effects of the non-selective adenosine receptor antagonist 8-phenyltheophylline (8-PT) and the selective A1 receptor antagonist ZM 241385 on vasodilatation evoked in cat hindlimb muscle by contraction Graphs show hindlimb vascular conductance calculated as hindlimb blood flow/arterial blood pressure, before (time 0) and during contraction at 3 Hz for 20 min. A, before and after 8-PT; B, before and after ZM241385. In each case, closed symbols show values after antagonist. All values are mean ±s.e.m.*P < 0.05, before versus after antagonist.
