Fig. 1 Schematic diagram of rabbit aorta with standardized sites from which tissue was taken for designated metabolic determinations. Deoxyglucose (DG), oxygen (O2), and lactic acid (LA), respectively, identify those segments from which tissue was taken for 2-deoxyglucose uptake, oxygen consumption, and lactic acid production determinations.

Fig. 2 Index of cellularity in proximal (cross-hatched bars) and distal (solid bars) rabbit aortic wall for control and experimental groups. Asterisks signify statistical difference (p < 0.01) compared with normal control animals. Bars represent one standard deviation from the mean.

Fig. 3 Radioautographs of proximal (A) and distal (B) aortic wall of a noncoarcted rabbit fed an atherogenic diet. Arrow indicates internal elastic lamina. A, Note foam cells in this section of atherosclerotic tissue proximal to the aortic wall containing black grains, indicating 14C-triply—labeled 2-deoxyglucose uptake, and relative lack of grains in the medial smooth muscle cells. Note the lack of nonspecific binding to extracellular matrix. B, Note the smooth muscle cells of the relatively thinner media of nonatherosclerotic distal aorta containing black grains indicative of 2-deoxyglucose uptake. (Hematoxylin counterstained; original magnification × 400.)
