Background: 11β-hydroxysteroid dehydrogenases (11β-HSD1&2) interconvert cortisol (F) and cortisone (E). Although 11β-HSD1 reductase activity has been measured in vivo, E production (dehydrogenase activity) has not been quantified using a Gold Standard technique, steady state tracer infusion.Aim: To develop a method to measure E production in vivo using the stable isotope tracer d2-cortisone (d2E).Me...
