Figure 5: The net tension of coronary arteries (a) after incubation with 0.1% or 3% PolyPHb. SNP-induced endothelium-independent relaxation (b) and ACh-induced endothelium-dependent relaxation (c) in coronary arteries after incubation with 0.1% or 3% PolyPHb. Control vessels were treated with KH solution alone. Values are presented as mean ± SD ( to 6 per group). versus the 0.1% PolyPHb group; versus the Control group. SNP: sodium nitroprusside; Ach: acetylcholine; KH: Krebs-Henseleit.
