Objective To investigate the protective effect of lipsomal clodronate against hepatic injury in rats with acute necrotizing pancreatitis (ANP). Methods 48 SD rats were randomly divided into control group, ANP group and lipsomal clodronate group, respectively. The models of ANP were established by injection of sodium taurocholate into the pancreatic capsule. Lipsomal clodronate was prepared by means of thin film. Blank liposomes and clodronate-containing liposomes was injected via caudal vein in ANP group and lipsomal clodronate group, respectively. The rats were sacrificed at 2, 6 h after ANP induction, the serum levels of ALT, AST and AMS, IL-6,IL-12 were measured, and pathologic changes of liver and pancreas were observed. Results At 6 h, serum level of ALT was (73 ± 11) U/L, (257 ± 33) U/L and (184 ± 29) U/L in control group, ANP group and lipsomal clodronate group, respectively;serum levels of AST were (190 ± 32)U/L, (590 ± 70)U/L and (430±52)U/L, respectively;serum levels of AMS were (814±80)U/L, (5031 ± 471) U/L and (2843 ± 236) U/L, respectively, serum levels of IL-6 were (26.7 ± 5.7) pmol/L, (218.0 ±4.7)pmol/L and (112.3 ± 8. O) pmol/L, respectively;serum levels of IL-12 were (4. 2 ± 1.0) pmol/L,(309.5 ± 8.5) pmol/L and (153.7 ± 6.3) pmol/L. The values in ANP group and lipsomal clodronate group were significantly higher than those in control group, while the values in lipsomal clodronate group were significantly lower than those in ANP group (P < 0. 01). Pathologic changes of liver and pancreas were significantly attenuated in lipsomal clodronate group. Conclusions Intravenous liposomal clodronate could exert protective effects on the hepatic injury in rats with ANP.
