we conclude that ( 1 ) tp may not substantially decrease the in vivo production of co by the small intestine at a dose which inhibits hepatic and splenic heme oxygenase , and ( 2 ) because after a heme load , heme is excreted into the intestine after tp administration , heme-degrading , co-producing processes in the intestine may contribute to an animal 's veco under such conditions .
