Effect of elevated l-Arg) during 2 h of CO (10⁻⁶ M) application on pial arteriolar diameter responses to l-Arg

	l-Arg Concentration
CO Duration	0 M	10−6 M	10−5 M	10−4 M
0 min	66 ± 8	69 ± 8	75 ± 8*	80 ± 8*
120 min	62 ± 7	66 ± 8	69 ± 8*	72 ± 8*

Values are means ± SE (diameters; in μm); n = 6 arterioles in 3 piglets.

^*P < 0.05 compared with no l-Arg.
