Steroid metabolism in the cat. Biliary and urinary excretion of metabolites of [4−14C]cortisone
Keyword(s):
1. [4−14C]Cortisone was administered to anaesthetized male cats as a single injection or as a 45–60min. infusion. 2. After the single dose a total of 69·6–89·6% of the radioactivity was excreted in bile, and 0·5–7·1% in urine. After infusion total recovery in bile was 73·4–92·1%, and 1·2–1·7% in urine. 3. When bile and urine samples were hydrolysed successively by β-glucuronidase, cold acid and hot acid, most of the radioactivity was converted into substances not extractable from neutral aqueous solution by ethyl acetate–ether. 4. In bile, metabolites hydrolysable by β-glucuronidase were found in only small proportions (3–4%) of the dose.
