Figure 4From: Pulmonary arterial dysfunction in insulin resistant obese Zucker ratsVasoconstrictor responses in conductance PA. (A) Contractile responses to KCl (80 mM, n = 5, left) and phenylephrine (10-7 M, n = 5, right) in conductance PA from lean and obese Zucker rats. (B) Serotonin concentration-response curve in conductance PA from lean and obese Zucker rats. Results indicate mean ± s.e.m.Back to article page
