This study was undertaken to clarify the effects of taurine on liver injury in rats with severe acute pancreatitis (SAP). Rats were randomly assigned to three groups: a sham operation (SO), a SAP (established by infusion of 5% taurocholate), and a SAP given taurine (Taur). At 12 and 24 h post-operation, taurine pretreatment significantly attenuated hepatic tissue injury induced by SAP, and concurrently, serum alanine aminotransferase, aspartate transaminase, and amylase levels were significantly reduced by taurine pretreatment. Compared with the SO group, the total and phosphorylated p38 mitogen-activated protein kinase (p38 MAPK) expression and nuclear factor-kappa B (NF-kappa B) activity of Kupffer cells (KCs) were significantly higher in the SAP group, but taurine pretreatment inhibited the total and phosphorylated p38 MAPK expression and NF-kappa B activity of KCs in the SAP group. The increase of tumor necrosis factor-alpha and interleukin-1 beta in cultured supernate of the SAP rat-derived KCs was also significantly inhibited by taurine pretreatment. These results suggest that taurine pretreatment ameliorated liver injury in rats with SAP mainly by inhibiting phosphorylated p38 MAPK and NF-kappa B activity in KCs, which may play an important role in liver injury.
