Transforming growth factor-beta1 (TGF-β1), a multi-functional cytokine, is involved in regulating a variety of cellular activities and the serum/plasma TGF-β1 level is altered with various diseases. However, most published reports have described adult patients, and so we investigated the clinical significance of serum TGF-β1 level in pediatric patients. The diagnostic application of the measurement of serum TGF-β1 level depends critically on the control value, however, there is no information on the control value of serum TGF-β1 for children.In the present study, we determined the serum TGF-β1 level of healthy Japanese children as a control value with enzyme-linked immunosorbent assay (ELISA). The serum TGF-β1 level of children (0–14 years old) was significantly higher than that of adults (over 15 years old) (p < 0.01). Thus, it is recommended that when the serum TGF-β1 levels of patients are evaluated, they should be compared with those of age-matched controls.

Although evidence exists pointing to the impact of maternal depression in puerperium upon mother-child interaction, longitudinal studies on this perspective are rare. Hence, this study was designed to examine the association between maternity blues and maternal attachment in the puerperium with depression in the mother and attachment after 1 year together with the factors involved. A questionnaire survey consisting of Zung’s Self-Rating Depression Scale (ZSDS) and a ‘maternal attachment’ scale, comprised of subscales on ‘core maternal attachment’ and ‘anxiety regarding children’, was conducted on mothers who had participated in a previous puerperium survey. The mean ZSDS score of 42.1 ± 7.45 after 1 year did not differ significantly from puerperium results. ‘Maternity blues’ was found to influence the maternal depression after 1 year, which was in turn associated with ‘core maternal attachment’ and ‘anxiety regarding children’, supporting the need for early intervention in maternity blues starting in the perinatal period for the mental health of mother and child.
