Pre-BK (pg/mL)			0.847
Post-BK (pg/mL)			0.573
Pre-apelin (pg/mL)			<
Post-apelin (pg/mL)			<
Pre-CRP (mg/L)			0.146
Post-CRP (mg/L)
Pre-MDA (nmol/mL)			0.140
Post-MDA (nmol/mL)

Notes. Data presented as mean ± standard deviation. value < 0.05; the difference was statistically significant. ACE, angiotensin converting enzyme; Ang II, angiotensin II; BK, bradykinin; CRP, C reactive protein; MDA, malondialdehyde; Pre, preoperation; Post, postoperation. Other abbreviations are as in Table 1.
