Means ± S.E. of changes in DHR fluorescence intensities along the arterioles and venules. Values are means ± SE of each group, CON (n = 5), DM (n = 5), DM + AAday2 (n = 6), and DM + AA6wk (n = 5), calculated by using the equation of: % change of ROS-associated fluorescent intensity = (I _1 min − I _base/I _base) × 100.

Group	% change of ROS in arteriolar wall	% change of ROS in venular wall
Control	34.08 + 15.62	38.31 + 18.71
DM	165.89 + 24.59*	172.26 ± 34.70∗,a
DM + AAday2	32.86 + 14.56#	49.59 ± 21.26#
DM + AA6wk	26.02 + 8.03#	49.91 ± 20.10#

*P < 0.001, significant difference compared to control.

^# P < 0.001, significant difference compared to DM.

^a P < 0.05, significant difference between ROS contents in arteriolar wall and venular wall in DM group.
