Fig. 4. Effects of bolus injections of ET-1 (120 pmol kg-1) before
pharmacological manipulation and after infusion of ETB-antagonist
(0.15 µmol kg-1) and tezosentan (15.4 µmol kg-1)
on relative changes in haemodynamic variables. Data points show means ±
S.E.M. for five individual experiments. Bars marked with different
letters are significantly different from each other (P<0.05).
