title: [Natural feeding and its importance in forming local immunological protection in the gastrointestinal tract during the neonatal period].
abstract: The immune proteins content in the breast milk at the 1st week of lactation as contrasted to the data obtained by investigating immunoglobulins in feces of newborns breast-fed was studied. Both in the breast milk and in feces the A-class immunoglobulins being of great importance in the immunological protection of the mucosae prevail. A high level of immune proteins resistant to proteolytic enzymes ensures the state of local passive immunity in neonates receiving breast milk.
