Figure 1 Apoptosis in isolated intact segments of rabbit aorta, intraluminally perfused with oxidized low density lipoprotein (oxLDL, 300 μg/ml; A) and oxidized lipoprotein(a) [oxLp(a), 30 μg/ml; B] for 6, 12, or 24 hours, the enhancement of apoptosis by the SOD inhibitor diethyl-dithio-carbamate (DDC, 10mm), and the inhibition of apoptosis by the O2--metabolizing enzymes SOD (0.1 μm) and catalase (100 U/ml). Apoptosis was determined by TUNEL staining, and the rate of apoptosis is expressed as a percentage of TUNEL-positive cells. Data are means ± se of four experiments. Symbols in A are: (□) control; () oxLDL; () oxidized LDL + DDC; () oxidized LDL + DDC + SOD/cat. Symbols in B are: (□) control; () oxLp(a); () oxidized Lp(a) + DDC; () oxidized Lp(a) + DDC + SOD/cat. *P < 0.05 oxLDL vs. oxLDL + DDC, respectively. oxLp(a) vs. oxLp(a) + DDC; #P < 0.05 oxLDL + DDC vs. oxLDL + DDC + SOD/catalase, respectively. oxLp(a) + DDC vs. oxLp(a) + DDC + SOD/catalase.
