From: The role of ATP and adenosine in the control of hepatic blood flow in the rabbit liver in vivo
The changes in (a) hepatic arterial pressure responses (Δ HAP) and (b) portal venous pressure responses (Δ PVP) to intra-portal injection of ATP. The adenosine receptor antagonist 8-phenyltheophylline (10 μM) significantly decreased hepatic arterial responses to ATP, while portal venous responses were unaffected (** p < 0.01, compared with before 8-SPT). The error bars in the graphs represent the SE.
