At block sites, the diameter of the FITC-albumin lumenal labelling at the final position blood reached was significantly lower in ischaemic DVR capillaries compared with that at the much smaller number of block sites in non-ischaemic controls (control 6.5 ± 0.3 μm vs. ischaemia 3.5 ± 0.4 μm; P = 0.039, Figure 4e). The gene discussed is ALB; the disease is ischemia.
