Values are expressed as mean ± S.E.M; n, aorta from individual mice. ACh, acetylcholine; Indo, indomethacin; L-NAME, Nω-nitro-L-arginine methyl ester; SNP, sodium nitroprusside; pEC50, sensitivity; Rmax, maximum relaxation. ND = not determined. * Significantly different from control treated group; # significantly different from diabetic group; ^ Rmax significantly different from control and Indo incubated aorta within the same treatment group.
