ABSTRACT
Objective To investigate the protective effects of lipsomal clodronate on renal injury in rats with severe acute pancreatifis and the assessment of renal injury. Method Totally 48 rats were randomly divided into three group:normal control group (C);SAP group, in which rats were treated with pure liposomal (P);treatment group, in which SAP rats were treated with liposomal clodronate disodium(T). The SAP model of rat was induced by injection of 5 % sodium taurochohte beneath the pancreatic membrane. Rats of normal control group received isovolumetric injections of 0.9% physiological saline solution instead of sodium taurocholate. Blood samples were collected to measure AMS,BUN,Cr,IL-6 and IL-12 at 2 hors, 6 hours after SAP. At the same time, the samples of pancreatic and renal tissues were taken for observing the pathological changes. Results Compared with controlgroup, serious renal and pancreatic damages were found in group P, and the AMS, BUN, Cr levels elevated signifi-candy (P < 0.01). Compared with group P,the renal and pancreatic damages were attenuated in group T, and the levels of Cr and AMS decreased significantly (P < 0.01), and the IL-6, IL-12 were decreased at 2 hours and 6 hours (P < 0.01). The BUN decreased significantly at6 hours (P < 0.05). Conciusions Excessive release of inflammatory mediator play an important role in renal injury in SAP. Lipsomal clodronate disodium can alleviate the damage of pancreas and kidney.
