Abstract:
Objective To investigate the effects of Shuangligan and Glycine on Thl/Th2 balancing on severe acute pancreatitis ( SAP) in rats. Methods Thirty-two Wistar rats weighing (260 ± 20) g were randomly divided into sham operation (SO) group, SAP group, SAP + Slg (with the treatment by Shuangligan) group and SAP + Gly (with the treatment by Glycine ) group. Each group included 8 rats, which accepted different treatment according to the experimental design. Changes of plasma level of endotoxin ( ET) and serum amylase (AMY) and the effects of Shuangligan and Glycine on Thl/Th2 ratio at the 24th hour after operation were observed respectively. Results The plasma endotoxin (ET) level ( (0. 67 ±0. 11) EU/ml),proinflammatory cytokine (INF-γ:(8.43 ± 0.86) ng/L, IL-12: (8.26 ± 1.97) ng/L) and Thl/Th2 ratio (0.36 ± 0.07) in SAP group were significantly higher than those in SO group( ET: (0. 44 ±0.07) EU/ml, INF-γ: (3. 80 ±0. 55) ng/L, IL-12: (3. 34 ± 1. 34)ng/L,Thl/Th2 ratio (0. 24 ±0. 05) ) (P <0. 05). Compared with SAP group, SAP + Slg and SAP + Gly group had remarkably decreased plasma ET level ( (0. 57 ± 0. 08,0. 52 ± 0. 04) EU/ml) (P < 0. 05) and the Thl/Th2 ratio reached equilibrium ( SAP + Slg group; (0. 29 ± 0. 04 ), SAP + Gly group: (0. 25 ± 0. 06 )) . Conclusions In the earlier stage of SAP, the rising plasma ET level may cause the overreaction of the cell mediated immune response, which leads to the aggravated damages in tissue cells. Our data indicates that Shuangligan and Glycine can restrain the formation of intestinal endotoxemia and alleviate or prevent the tissue injuries.
