Estrogen improves the hyperdynamic circulation and hyporeactivity of mesenteric arteries by alleviating oxidative stress in partial portal vein ligated rats

Figure 3 Hydrogen peroxide determination. The hydrogen peroxide concentrations of the superior mesenteric arteries were obtained from sham operation (SO) and partial portal vein ligation (PPVL) rats 14 d after surgery. ^aP < 0.05, ^bP < 0.01 vs SO; ^cP < 0.05, ^dP < 0.01 vs PPVL + placobo (PLAC); ^eP < 0.05, ^fP < 0.01 vs PPVL + estrogen (E2).
