Abstract：
:Changes in bile ducts in cholestasis are characterized by activation of proliferation and hypertrophy of cholangiocytes and degenerative and necrobiotic changes in ductal epithelium. Long-term cholestasis led to massive necrosis of cholangiocytes. Inflammatory changes in the choledochal mucosa were most pronounced in patients with choledocholithiasis.

杂志文章abstract：:We studied the effects of ionophores on activity of Na+,Cl-(HCO 3- )-ATPase. The most significant effect on the activity of this enzyme was produced by protonophore 2,4-dinitrophenol. The effect of this drug largely depended on the cation and anion composition and pH of the incubation medium and its pH. Activity of Na...
