Figure 4. — Histological analysis of haematoxylin and eosin stained rat heart tissues of control, Fe₂O₃NP-exposed group, AgNP-exposed group, and Fe₂O₃NP and AgNP-coexposed group. (A) Control rats demonstrated normal myofiber cells and normal architecture. (B) Heart tissues of Fe₂O₃NP-exposed group revealed myocardial degeneration changes. (C) Heart of AgNP-exposed group revealed fragmentation of sacroplasm and degeneration changes in myocardial fibers. (D) Heart of the Fe₂O₃NP and AgNP-coexposed group revealed loss of cross striation and severe myocardial degeneration changes (magnification, ×400). Fe₂O₃NP, iron oxide nanoparticle; AgNP, silver nanoparticle.
