Abstract

The stop flow patterns of free and glucuronide conjugated Cortisol were studied in five anesthetized dogs. The results indicate that free Cortisol was reabsorbed primarily along the distal tubules. ACTH had no effect on the reabsorption of free Cortisol by the distal tubules, but it did increase free Cortisol reabsorption by the proximal tubules. The stop flow patterns for Cortisol glucuronide demonstrate that this conjugated steroid was secreted along the entire length of the renal tubules and ACTH had no effect on its secretion.
