Effect of verapamil on nitric oxide synthase in a portal vein-ligated rat model: Role of prostaglandin

Figure 1 Portal pressure responses to verapamil in four groups of rats: ^aP < 0. 05 vs sham-operated control. PVL: portal vein ligated.

Figure 2 Effect of verapamil in combination with NNA (■light grey), INDO (■dark grey ) and NNA plus INDO (■black ) on cardiac output (A), mean arterial pressure (B), portal venous inflow (C), portal pressure (D), hepatic arterial flow (E), and portal systemic shunting (F) in PVL rats. ^aP < 0.05 vs control group.

Figure 3 Effects of verapamil in combination with NNA (80 mg/Kg), INDO (2 mg/Kg) and NNA plus INDO on splanchnic blood flow in sham-operated and PVL rats after 15 days. A: verapamil plus NNA plus INDO; B: verapamil alone; C: verapamil plus NNA; D: verapamil plus INDO. ^aP < 0.05 vs control group.
