Quantification of occlusive (a) and plexiform (PXL) lesions (c) and assessment of neomuscularization of small-size pulmonary arteries (b) in rats treated with either Sugen 5416 (SU Day 26 group; n = 8) or the combination of Sugen 5416 + 10 days of HAB treatment (Group SU+HAB Day 26; n = 8). The combination treatment resulted in development of numerous occlusive lesions in small-size (<50 μm) pulmonary arteries (a) and formation of PXL (d–f) similar to those seen in Sugen+hypoxia model (g).
