2 Fig. 1 Macroscopic in vivo photographs. (Original magnification × 10.) A, Aneurysmal SHR host aortic allograft 18 weeks after transplant. B, WKY host aortic allograft, as in A. One grid square = 1 mm.

3 Fig. 2 Photomicrographs of SHR host (A) and WKY host (B) aortic allografts. (Hematoxyling and eosin stain. Original magnification X40). Vascular lumen at bottom of photograph. Note mononuclear adventitial infiltrate, lack of smooth muscle cell nuclei, and intimal proliferation.

4 Fig. 3 Percent increase of transverse diameter of aortic graft at harvest. Auto, Autograft; Allo, allograft; Sens WKY, skin graft-sensitized WKY host; Sens SHR, skin graft-sensitized SHR host.

5 Fig. 4 A, Antihypertensive treatment of SHR: treated versus untreated SHR's systolic blood pressure. Open circles represent treated SHR host, open triangles represent untreated SHR host, and filled symbols represent directly measured arterial pressure. B, Treated versus untreated SHR's mean transverse aortic diameter as measured by MRI. Symbols as in A; filled symbols represent visually measured aortic diameters at harvest.
