1. On the regulation of hepatic cholesterol and bile acid metabolism in gallstone patients
Sammanfattning : The liver plays an important role in the regulation of cholesterol homeostasis, therefore also in the pathogenesis of arteriosclerosis and gallstone disease. The quantitatively most important way by which cholesterol is removed from the human body is via the bile, either as free cholesterol or after transformation to bile acids. LÄS MER
2. Studies on human sterol 27-hydroxylase with emphasis on its mechanism of regulation and metabolic consequences of a deficient enzyme
Sammanfattning : Sterol 27-hydroxylase (CYP27A1) is a mitochondrial cytochrome P-450 enzyme present in most animal cells. In hepatocytes, CYP27A1 has an important role in connection with biosynthesis of bile acids from cholesterol. LÄS MER
3. Steroids and bile acids in intrahepatic cholestasis of pregnancy : effects of treatment with ursodeoxycholic acid
Sammanfattning : A method permitting simultaneous analysis of individual steroid hormone metabolites and bile acids in different forms of conjugation in serum and urine was established. Total bile acids and neutral steroids were extracted from human serum or urine with octadecylsilane-bonded silica, separated into different groups of conjugates by anion-exchange chromatography and analyzed by fast atom bombardment mass spectrometry.
