Effect of α-, β₁-, or β₃-adrenergic receptor antagonists on intestinal OEA levels (pmol/g)

	α-Adrenergic antagonist		β1-Adrenergic antagonist		β3-Adrenergic antagonist
	V	Prazosin	V	CGP2071	V	SR59230
FD	68.1 ± 7.4	55.4 ± 5.4	58.2 ± 8.3	67.1 ± 3.5	90.3 ± 9.5	114.2 ± 8.9
RF	172.1 ± 25	123.5 ± 21.7	155.5 ± 21.7	108 ± 9.4	186.5 ± 23.6	172.3 ± 23.8

Administration of α-, β₁-, or β₃-adrenergic receptor antagonists does not affect jejunal OEA levels in refed rats. Thirty minutes of refeeding (RF) after 24 h of food deprivation in vehicle (V)-treated animals increased jejunal OEA levels compared to 24 h food deprivation alone (FD). Systemic treatment with α- (prazosin), β₁- (CGP2071), or β₃- (SR59230A) adrenergic receptor antagonists did not alter OEA mobilization. Results are expressed as mean ± SEM; n = 6/condition.
