The changes in myocardial NO and mitochondrial ROS under non-diabetic conditions.

	ROS	NO
N	5.32 ± 0.13∧	1.22 ± 0.08∧
I/R	11.46 ± 0.15	2.21 ± 0.12
SPC	8.13 ± 0.17∧	3.20 ± 0.13∧
SPC + 2ME2	11.80 ± 0.12#	1.97 ± 0.10#
2ME2	11.86 ± 0.15#	2.02 ± 0.07#

Data are presented as the mean ± SEM (n = 6). ROS: Reactive oxygen species; NO: Nitric oxide; N: normal; I/R: ischemia reperfusion; SPC: sevoflurane post-conditioning; 2ME2: 2-Methoxyestradiol.
