H&E staining of basilar artery (Magnification: × 400). A (control group) shows spreading of endothelial cells and no thickening of the vessel wall; B (SAH group) shows significant thickening of vessel wall and shrinkage of endothelial cells, manifesting battlement-like morphological changes; C (SAH + insulin group) exhibits significant vessel wall thickening and endothelial cell shrinkage with battlement-like changes too; D (SAH + vitamin C group) shows significant wall thickening and endothelial cell shrinkage, manifesting battlement-like changes; E (SAH + insulin + vitamin C group) shows spreading of endothelial cells with moderate wall thickening.
