Fig. 1.Hemodynamic effects of anandamide in anesthetized mice. Representative recordings of the effects of anandamide [20 mg/kg i.v.,N-arachidonoyl-ethanolamine (AEA)]on mean arterial pressure (MAP,top panel), cardiac contractility (left ventricular systolic pressure (LVSP)anddP/dt(
dPdt);middle panel) and pressure-volume relations (bottompanel) in a pentobarbital-anesthetized C57BL6 mouse. The five parts of themiddleandbottom panelsrepresent baseline conditions (Bl
), phase I (I), phase II (II), and phase III (III
)of the anandamide response, and recovery10 minfollowing the injection. Thearrowindicates the injection of the drug. The decrease of the amplitude of PV loops and shifttothe right indicate decrease of cardiac contractile performance
