Fresh healthy human erythrocytes were treated by four kinds of bile acid solution (DOC, GDC, C-Na and GC-Na) at physiological and pathological concentrations of human serum level. The more hydrophobic bile acids (DOC and GDC) significantly affected lipid components of erythrocyte. membranes and morphology at concentration of 0.5 mmol/L and 1.0 mmol/L. To the extent of he-molysis DOC and GDC were more hemolytic than C-Na and GC-Na. Additionally the erthrocytes from patients with biliary obstruction were also studied. The results suggest that the more hydropho-bicity of bile acid, the more erythrocyte damage. The hydrophobicity was associated with the structure of bile acid molecules.

Objective To investigate the relationship of diabetic nephropathy with serum endothelin-1(ET-1) and C-reactive protein(CRP). Methods Levels of blood pressure, glucose, lipid, creatinine,ET-1,CRP and urinary albumin excretion(UAER) were measured and calculated in 86 patients with type 2 diabetes mellitus(T2DM)and 30 healthy subjects.
