目的 探討肝細(xì)胞膜鈉泵(Na+K+ATPase)活性變化在膽紅素鈣結(jié)石成石過程中的作用。方法采用膽紅素鈣結(jié)石兔模型進(jìn)行研究，對照組28只，膽道不全梗阻組（BO組）36只，膽道不全梗阻加感染組（BOI組）39只，各組再按術(shù)后處死時間3 d、7 d、14 d及20 d時相分組。動態(tài)測定各組各時相肝細(xì)胞膜鈉泵活性、肝細(xì)胞鈣及膽汁中膽汁酸含量。 結(jié)果BO組及BOI組肝細(xì)胞膜鈉泵活性及膽汁中膽汁酸含量進(jìn)行性下降，肝細(xì)胞鈣含量呈進(jìn)行性增多，與對照組相比差異有顯著性意義（P＜0.01），但BOI組上述變化較BO組明顯（P＜0.05）。結(jié)論膽紅素鈣結(jié)石成石過程中存在肝細(xì)胞膜鈉泵活性的進(jìn)行性下降，鈉泵活性下降引起肝細(xì)胞鈣超負(fù)荷及膽汁中膽汁酸含量下降，從而促進(jìn)成石。細(xì)菌感染加重上述變化，使結(jié)石形成增多。
