Early diagnosis and therapeutic effect of rhubarb for septic acute kidney injury / 中国现代医生

ABSTRACT

Objective To study early diagnostic index of septic acute kidney injury(AKI) and protective effect of rhubarb on septic AKI. Methods Sixty rats were randomly divided into the following 3 groups:model group (A), treatment group (B) and control group (C). Each group contains 20 rats. Rats from group A were received a intraperitoneal injection of lipopolysaccharide (LPS) at a dose of 5 mg/kg to induce AKI. Rats from group B were given rhubarb powder solution by oral administration immediately after LPS injection. Rats from group C were treated with the same volume of normal saline (NS) by intraperitoneal injection. Both serum level of creatinine (Scr) and urinary levels of Netrin-1 and KIM-1 of rats in 3 groups were detected in the different time points of treatment (0 h, 1 h, 6 h and 24 h). Results The levels of KIM-1 and CR in rats treated with LPS were obviously increased at the time point of 6 h (P<0.05). The urinary lev-el of Netrin-1 began to increase at the time point of 1 h and reached the highest level at the time point of 6 h, then gradually decreased at the time point of 24 h after the injection of LPS. In group B, the levels of Scr, Netrin-1 and KIM-1 were significantly lower as compared with group A (P<0.05). Conclusion The urinary level of Netrin-1 might has early diagnostic value in septic acute kidney injury. Rhubarb could protect the kidney of AKI model rats by de-creasing the serum level of Scr, urinary levels of Netrin-1 and KIM-1.
