title: [Absorption of 241Am in the gastrointestinal tract].
abstract: In experiments with rats a study was made of a number of factors influencing the resorption of 241Am from the gastrointestinal tract (GIT). The resorption of 241Am from GIT was found to be 120-245 times more intensive in neonatal rats, during the first 21 days after birth (a milk diet), than in adult animals. A milk diet for adult rats produced a 5-fold increase in the resorption of 241Am from GIT. The additional administration of digestive enzymes, as a homogenate from pancreas and small intestine, produced a 7--9-fold increase in the rate of 241Am resorption from GIT.
