Effect of the CB2 selective antagonist SR144528 (1 μM, n=5) on the inhibitory actions of 1 μM noladin ether on frequency-dependent vasorelaxation to EFS in the rat isolated mesenteric arterial bed. Three consecutive curves were constructed to EFS: the first acted as a control, noladin ether was added to the perfusate, then EFS I and EFS II were constructed. Data are presented as means±s.e.m. *P<0.05 with respect to control.
