Decreased hepatic proinflammatory cytokines in liver after hemorrhage/resuscitation in rats treated with polyphenol extract. Water- and polyphenol (PP)-gavaged rats were subjected to hemorrhage/resuscitation or sham operation, as described in Fig. 2, and livers were harvested at 18 h after resuscitation for measurement of TNFα, IL-1β and IL-6, as described in Materials and METHODS. Group sizes were 4-10 per group. *, p < 0.05 vs. sham; #, p < 0.05 vs. water gavage.
