Figure 1

The protocol of phase II experiment. C1, C2, and C3 are groups of normal rats. P1, P2, and P3 are groups of pulmonary artery hypertension rats. T0: baseline values of hemodynamic data were recorded. T1: hemodynamic data were recorded after normal saline or LPS injection. T2: hemodynamic data were recorded after normal saline or CNP injection.
