Celsior液与UW液对无心跳大鼠供肝保存效果的比较

Objective To compare the effects of Celsior (CS) solution vs University of Wisconsin (UW) solution on preservation of non-heart- beating donor (NHBD) livers in rats. Methods The healthy male SD rats were taken as donors and recipients. The thoracic descending aorta and supradiaphragmatic inferior vena cava were cross-clamped for 10 min to induce ischemia as a NHBD model. After flushed with the cold CS or UW solution, NHBD livers were stored at 4℃ for 8 h or 16 h. Then they were transplanted using the two-cuff technique with arterial reconstruction. Accordingly, the recipients were divided into four groups: CS 8 h, UW 8 h, CS 16 h and UW 16 h groups. The bile discharge, liver enzymes (ALT and AST), ET-1, IL-1 and TNF-alpha levels in serum at 1, 3, and 6 h after reperfusion were measured. Histopathological examination was carried out by HE staining, and the 7-day survival rate was observed. Results As compared with a homogenous appearance in the NHBD livers perfused with CS solution, the NHBD livers perfused with UW solution showed a heterogenous appearance, with more or less mottling. In the CS 8 h group there were more bile discharge at 1 h, lower ALT and AST levels at 1, 3 and 6 h, and lower serum ET-1, IL-1 and TNF-alpha ? levels at 1 and 3 h after reperfusion than the UW 8 h group (P<0.05). Histopathological examination showed a well-preserved hepatic architecture, milder portal congestion and inflammatory infiltration in CS 8 h group as compared with UW 8 h group. The 7-day survival rate in CS 8 h and UW 8 h groups was 58.3% and 25.0% respectively (P<0.05). There were no significant differences in bile discharge, ALT, AST, ET-1, IL-1 and TNF-alpha ? levels at different time points between CS 16 h and UW 16 h groups (P>0.05), and histopathological examination showed no much difference in the tissue damage between two groups; all recipients died within 3 days (P>0.05). Conclusion CS was more effective than UW in preserving NHBD livers after 8 h of cold storage, which may be due to the better perfusion of CS and inhibition of Kupffer cells, but it had better preserve NHBD livers with CS no more than 16 h.
