Abstract:
Objective To explore the effect of relative warm ischemia (RWI) on bile nature and component in rats self-liver transplantation.Methods Thirty two rats were randomly divided into group Ⅰ (control group),group Ⅱ (RWI 0 min),group Ⅲ (RWI 30 min),and group Ⅳ (RWI 60 min).The levels of bile phospholipids (PL),total bile acids (TBA),and PL/TBA ratio were detected early after self-liver transplantation.The concentration changes of hydrophilic and hydrophobic bile acids were examined.Results Only PL concentration of group Ⅱ seemed to be lower than that of group Ⅰ (P ＜ 0.05),without any change for other indexes.Compared with group Ⅱ,only the PL and TBA concentrations of the group Ⅲ were decreased significantly (P ＜ 0.05),and no significant difference was found between two groups on PL/TBA ratio and mole fractions of bile acids (P ＞ 0.05).Compared to group Ⅱ,the concentrations of PL and TBA,PL/TBA ratio,and the mole fraction of taurocholic-β-mouse acid (T-β-MC) were much lower in group Ⅳ (P ＜ 0.05),and the mole fraction of taurocholic acid (TC) were higher in group Ⅳ (P ＜ 0.05).Conclusions RWI caused changes of PL/TBA ratio,hydrophilicity and hydrophobicity of bile early after liver transplantation,and the changes were directly proportional to the RWI time.The property of bile in early transplantation seemed not to be changed when the relative warm ischemia time was less than 30 min.When the RWI time was longer than 60 min,the bile component was changed obviously and the toxicity was increased.In liver transplantation,arterial anastomosis should be completed as soon as possible,and the RWI time should be less than 30 min.
