11β-hydroxysteroid dehydrogenase type 2 activity in rat intestine.

<p>Enzyme activity in total tissue was assessed by incubating fresh tissue sections in the presence of ³H-labelled substrate corticosterone. Metabolites were separated by thin-layer chromatography. Conversion rates of ³H-corticosterone (B) into ³H-11-dehydrocorticosterone (A) were calculated as percentage of dpm A/(dpm A+dpm B) and expressed per area of tissue. Sham normal salt: open circles, UNX normal salt: closed circles, sham high salt: open squares, UNX high salt: closed squares. The median for each group is given by a horizontal line (n = 7).
