Figure 3

Contraction induced by 5-HT, ET-1, Phe and high potassium solutions (KCl). Isometric tension measurements were recorded on intrapulmonary arteries in response to cumulative concentrations of 5-HT (A, n = 19 - 31), ET-1 (B, n = 17 - 26), Phe (C, n = 21 - 29) and KCl (D, n = 10 - 20) in normoxic, chronic hypoxic and monocrotaline-injected rats (black, white and grey squares respectively). Data are means ± SEM and are expressed as a percentage of the high potassium solution (80 mM)-induced response. ** means a significant difference for P < 0.01.
