Dilation of pial arterioles in newborn pigs (n=9) (A), 7-week old pigs (n=6) (B), juvenile pigs (n=7) (C) and adult rats (n=10) (D) to ascending doses of CO alone, with L-nitro arginine (LNA, 10−3 M), and with LNA plus sodium nitroprusside (SNP, 2×10−7 M). Values are mean ± SE and *,#,**, and t are P<0.05 compared to zero % change, 10−7M CO, without LNA, and LNA+SNP, respectively.
