Changes in proteases antiproteases and bioactive proteins from mother’s breast milk to the premature infant stomach

摘要

ObjectivesOur previous studies suggested that human milk proteases begin to hydrolyze proteins in the mammary gland and continue within the term infant stomach. No research has measured milk protease and pepsin activity in the gastric aspirates of preterm infants after human milk feeding. This study investigated how the concentrations of human milk proteases and protease inhibitors changed in the premature infant stomach.
