Figure 4. Long-term management of MMI induced intracellular hemorrhage in the unstable carotid artery plaque models.

(A and B) HE staining was used to assess the plaque size in different groups. (C) Sporadic hemosiderin-laden macrophages were stained by Perl’s staining for iron (stained blue; *P<0.05, compared with the water-2-week group; #P<0.05, compared with the MMI-2-week group).
