Effects of (a) 0.1 μM (n=6), (b) 1 μM (n=4) and (c) 3 μM noladin ether (n=5) 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, ^**P<0.01 with respect to control, ^***P<0.001 with respect to control.
