title: [Effect of several factors on lead absorption in the intestine].
abstract: Experiments were made on 270 rats to examine lead absorption and the effect on this process of fasting, food intake, preliminary contact of the mucosa with selenium, iron and calcium, a single enteral and parenteral administration of these elements. Lead absorption was observed in all the parts of the intestine. Lead binding to the intestinal mucosa was reduced by food intake one hour before investigation, preliminary contact of the mucosa with selenium, calcium, particularly with iron, as well as by a single administration of iron and calcium. Selenium did not produce any substantial effect on absorption. The conclusions are made about the necessity of the organization of the treatment and prophylactic nutrition for workers.
