Haemodynamic responses to human urotensin II (hUII; 3 nmol kg⁻¹) in the presence of indomethacin (5 mg kg⁻¹ h⁻¹; open circles) or its vehicle (10 mM Na₂CO₃ at 0.4 ml h⁻¹; closed circles) in conscious SD rats (n=8). Values are mean and vertical bars show s.e.m. ^*P⩽0.05 vs baseline (Friedman's test). Between-group differences are given in the text. Note the change in time scale between 30 and 60 min.
