Figure 3: Histological images of carotid artery from rat ferric chloride model. (a) Longitudinal section of rat carotid artery 20 minutes after initiation of 20% ferric chloride injury. Arterial wall and blood show marked degenerative or denaturation changes at site of injury (arrows), wall constriction, and brown color at blood-vessel interface. Hematoxylin eosin stain. (b) Higher magnification of attached thrombus (*) shows absence of cellular and fibrillar structures and rather homogeneous appearance. Hematoxylin eosin stain.
