| Research Abstract |
We have started investigation of the effects of fetal infection as a fetal factor affecting development of allergy and breast milk as an extra fetal factor during the early stage
A prospective epidemiological study on the effect of intrauterine infection on the development of allergies was performed. Clinical sepsis in neonates caused by intrauterine infection might reduce the risk of developing allergic diseases in early childhood among children with maternal atopy
We focused on breast milk as an extra fetal factor during the early period after birth in infants. The relation of factors (TGF-β1, TGF-β2, IFN-γ, IFN-γ inducible protein 10 kDa ; IP-10, and solubleCD30) in breast milk to the development of allergy was investigated. TGF-β1 levels in breast milk were low in cases of development of allergic diseases by two years of age. There were no significant differences in the other factors. TGF-β1 in breast milk inhibits the development of allergy during the early infancy
