The changes of ACE, ACE2, ACE/ACE2, Ang II and Ang-(1–7) in the HD patients (n = 360) before (pre-HD) and after (post-HD) a single HD session.

	Pre-HD	Post-HD
BUN (mg/dL)	71.1 ± 17.5	17.3 ± 5.6***
Creatinine (mg/dL)	9.08 ± 2.10	2.96 ± 1.10***
ACE (RFU/μL/h)	133 ± 40	140 ± 45*
ACE2 (RFU/μL/h)	8.9 ± 2.6	9.0 ± 2.8
ACE/ACE2	15.9 ± 6.2	16.9 ± 7.6
Ang II (ng/mL)	106 ± 31	111 ± 31*
Ang-(1–7) (ng/mL)	15.0 ± 4.6	14.9 ± 4.1

Data were expressed as mean ± SD.

^*p < .05 and

^***p < .001, pre-HD vs. post-HD.

ACE: angiotensin converting enzyme; ACE2: angiotensin converting enzyme; Ang II: angiotensin II; Ang-(1–7): angiotensin 1–7; HD: hemodialysis; pre-HD: before hemodialysis; post-HD: after hemodialysis.
