Decreased ALT release after hemorrhage/resuscitation in rats treated with polyphenol extract. Water- and polyphenol (PP)-gavaged rats were subjected to sham operation or bled to a mean arterial pressure of 40 mm Hg for 1 h and resuscitated, as described in MATERIALS AND METHODS. Blood was collected at 10 min and 2 h after resuscitation for ALT measurement. Group sizes were 4-10 per group. *, p < 0.05 vs. sham; #, p < 0.05 vs. water gavage.
