Stability of a rat model of prehepatic portal hypertension caused by partial ligation of the portal vein

Table 1 PVP changes (cmH₂O), (mean ± SD)

Groups	wk-0	wk-2	wk-6	wk-10
G-I (SO, n = 10)	9.15 ± 0.58	9.22 ± 0.49	9.27 ± 0.43	9.21 ± 0.49
G-II (PVL, n = 16)	9.21 ± 0.63	17.32 ± 1.77a	17.36 ± 1.93a,b	16.82 ± 2.20a,b

Portal vein pressure (PVP) changes at four time periods were compared.

^aP < 0.001 vs value of G-I;

^bP < 0.001 vs value of wk-2 in G-II. wk-0: before ligation; wk-2, wk-6, wk-10: 2 weeks, 6 weeks and 10 weeks post-surgery, respectively.

Groups	wk-0	wk-2	wk-6	wk-10
G-I (SO, n = 10)	1.90 ± 0.28	1.93 ± 0.24	2.03 ± 0.23	2.04 ± 0.25
G-II (PVL, n = 16)	2.07 ± 0.40	3.94 ± 1.33a,b	4.07 ± 1.37a,b	4.17 ± 1.44a,b

^aP < 0.01 vs value of G-I;

^bP < 0.01 vs value of wk-0 in G-II. wk-0: before ligation; wk-2, wk-6, wk-10: 2 weeks, 6 weeks and 10 weeks post-surgery, respectively.
