Basal MAP and HR before arterial injection of α,β-me-ATP

	Baseline MAP, mmHg		Baseline HR, beats/min
α,β-me-ATP	Control	Occluded	Control	Occluded
0.0625 mM	96 ± 6	100 ± 9	378 ± 12	388 ± 17
0.125 mM	97 ± 9	103 ± 10	385 ± 15	390 ± 18
0.25 mM	95 ± 5	100 ± 6	395 ± 20	387 ± 20

Values are means ± SE. Number of animals = 8 in control and 9 in occluded rats. α,β-me-ATP, α,β-methylene ATP; MAP, mean arterial pressure; HR, heart rate. There is no significant difference among basal values.
