Abstract:
Objective To evaluate the hepatic pathological damage after orthotopic liver transplantation (OLT) in rats with integrated backscatter (IBS). Methods Thirty-two SD rats and 40 Wistar rats were included, and stable OLT models were established except 8 Wistar rats as blank group. The rat models were randomly divided into 4 groups (each n=8):normal group (given no treatment), CsA-treated group (30 mg/[kg·d]), SIN-treated group (40 mg/[kg·d]), SIN and CsA-treated group (SIN 40 mg/[kg·d]+CsA 15 mg/[kg·d]). Hepatic IBS (peak to peak intensity:PPI; average image intensity:AII; standard deviation of image intensity:SDI) was measured on 4th and 10th day after OLT. The rats were sacrificed and a part of liver was cut off for pathological examination. Result Four days later, AII of control and SIN groups were higher than those in other groups (P<0.05), and of CsA-treated and SIN+CsA-treated groups were higher than that of blank group (P＜0.05), while no difference of PPI and SDI was detected between each two groups. Ten days later, AII in CsA-treated, SIN+CsA-treated and SIN-treated groups were lower than that of control group (P＜0.05), no difference of PPI and SDI was detected between each two groups. IBS was positively correlated with liver pathological damage (r=0.814, P＜0.01). Conclusion Detecting hepatic IBS contributes to the diagnosis of the level of liver damage after OLT.
