Correlation between radial artery ischemia and tissue lipid peroxide measurements. r = 0.426, R2 = 0.181, TLPO = IT. (TLPO = tissue lipid peroxide [nmol/g-wet tissue]; IT = ischemia time [minutes]; numbers on the graph represent the subjects of the groups; solid line represents the linear regression fit line; dashed lines represent the 95% confidence limits for the linear regression.)

3. Fig 2
Correlation between radial artery tissue lipid peroxide (TLPO) levels and total electron microscopic score. r = 0.581, R2 = 0.338, TEMS = TLPO. (TLPO = tissue lipid peroxide [nmol/g-wet tissue]; TEMS = total electron microscopic score of the sample; numbers in the graph represent the subjects of the groups; solid line represents the linear regression fit line; dashed lines represent the 95% confidence limits for the linear regression.)

Correlation between radial artery ischemia time and total electron microscopic score. r = 0.734, R2 = 0.538, TEMS = IT. (TEMS = total electron microscopic score of the sample; IT = ischemia time [minutes]; numbers in the graph represent the subjects of the groups; solid line represents the linear regression fit line; dashed lines represent the 95% confidence limits for the linear regression.)

5. Fig 4
Electron micrograph (original magnification ×7,500) of the arteries in group I (A and B), group II (C and D), group III (E and F), and group IV (G and H). (A) Thin endothelial layer (E), subintimal edema (*), and swollen mitochondria (arrows). (B) Perinuclear edema (PO) in a fibroblast and intercellular edema (O). (C) Discontinuity in the endothelial wall (double arrow). In this group, normal histology of the endothelial layer was completely disappeared (E). Additionally, subintimal edema (*) and swollen mitochondrion (arrow) were present. (D) Intercellular edema located around the fibroblasts (O), in tunica adventitia of the blood vessels in group II. (E) Normal endothelial wall (E), swollen mitochondria in the cytoplasm of the endothelial cells (arrows), and edema in the tunica media of an artery (O). (F) Intracellular edema (IO) and intercellular (O) edema in the tunica media of an artery in group III. (G) Very small degree of edema (O) and a swollen mitochondrion (arrow) in the endothelium of an artery in group IV. (H) A fibroblast (F) with swollen mitochondria (arrows) and intercellular edema (O) in the tunica adventitia of an artery in group IV.
