Figure. 1. Serum amyloid P component (SAP) in normal and atherosclerotic aortic intima.
A to F. Immunohistochemical staining of SAP. Aortas from normal, moderate and advanced atherosclerotic patients were stained with hematoxylin/eosin (A, C and E) or immunostained with anti-SAP serum (B, D and F). Positive immunostainings are identified as a brown reaction product. Original magnification, x50. G. Quantification of SAP in normal and atherosclerotic intima. SAP content in normal, moderate and advanced atherosclerotic intima was quantified with electroimmunoassay. *p < 0.05, moderate versus normal and advanced versus moderate.
