Figure 6From: Temporal patterns of blood flow and nitric oxide synthase expression affect macrophage accumulation and proliferation during collateral growthA, Quantification of resident macrophages. per collateral section in the absence (occlusion) and presence (occlusion + GTN) of continuous, peripheral GTN infusion (10 μg/h over 72 h) 72 h after femoral artery occlusion, *p < 0.05 vs. occlusion. B, Quantification of proliferation in the absence (occlusion) and presence (occlusion + GTN) of continuous, peripheral GTN infusion (10 μg/h over 72 h) 72 h after femoral artery occlusion, *p < 0.001 vs. occlusion. C, Quantification of collateral-dependent tissue perfusion in the absence (occlusion) and presence (occlusion + GTN) of continuous, peripheral GTN infusion (10 μg/h over 72 h). Ischemic limb perfusion 72 h after femoral artery occlusion was expressed as a ratio of fluorescent microsphere counts in ischemic soleus muscle and related to non-femoral occluded leg (set as 1).Back to article page
