Donaldson, Robert M. Jr. published the artcileUrinary excretion of indolic compounds in rats with intestinal pouches, Application In Synthesis of 2642-37-7, the publication is American Journal of Physiology (1961), 794-6, database is CAplus and MEDLINE.
The urinary excretion of indican and free and total indoleacetic acid is significantly increased in the rat in the presence of a localized area of intestinal stasis produced surgically by the creation of a pouch in the small intestine. Tryptamine, serotonin, and 5-hydroxyindoleacetic acid excretion in the urine is not altered. Intestinal stasis and bacterial activity within the pouch are responsible for the increased amounts of indican and indoleacetic acid in the urine.
