Fig. 3. Tension recordings showing the effect of SNP (A), ACh (B) and nicotine (C) on the crocodile right aorta (A,C) and dorsal aorta (B). The vessels were incubated with ET-1 (10-8 mol l-1) until a maximal constriction was achieved, and then either SNP (10-4 mol l-1), ACh (10-5 mol l-1), or nicotine (3x10-4 mol l-1) was added. All three chemicals caused a marked vasodilation. (D) Mean response of pre-constricted right aorta (filled bars) and dorsal aorta (open bars) to SNP (10-4 mol l-1), ACh (10-5 mol l-1) and nicotine (3x10-4 mol l-1). Values are means ± s.e.m., N=5.
