[Perinatal fetal distress: correlations between Apgar score at birth and assay of CK-BB in umbilical cord blood].

32 newborn infant's umbilical cord blood CK-BB activity was tested at birth. 14 of them had a superior to 7 Apgar score at first and fifth minutes, whereas 18 newborn infant Apgar score was inferior to 7. The CK-BB activity was significantly higher in newborn infants having a low Apgar score at birth.

Comparison of prolactin response to suckling and breast pump aspiration in lactating mothers.

Prolactin release following breast pump aspiration is less than that following suckling. The long-term effects of this decreased prolactin response are not yet known and therefore the use of the breast pump should be limited to selected cases and for the shortest possible time.
