Secretory Iga Level in Pharyngeal Mucous of Infants with Different Feeding Methods at the Age of Four to Eight WeeksMaternal and Child Health and Global Health Department, Faculty of Medicine, University of the Ryukyus, b987390{at}med.u-ryukyu.ac.jp
Maternal and Child Health and Global Health Department, Faculty of Medicine, University of the Ryukyus The stimulating effect of human breast milk on the mucosal immunological development of recipient infant has been speculated. The objective of this study was to clarify the influence of breast feeding on the level of secretory IgA (sIgA) of infants. The level of sIgA in pharyngeal mucous among 79 healthy infants aged 4-8 weeks with different feeding methods was estimated. The concentrations of sIgA and protein were measured after the mucous absorbed by the throat swab was emulsified in saline. The level of sIgA was expressed as a percentage of the total protein content (sIgA % protein). The difference of the mean sIgA % protein was not significant among infants with different feeding methods. The results suggest that breast milk does not influence the sIgA levels of infant. Breast feeding may promote specific sIgA production without raising the total level of sIgA. Asia Pac J Public Health 2003; 15(2): 124-126.
