Oxytocin and prolactin responses in long-term breast-feeding.

摘要: Plasma levels of oxytocin and prolactin were measured before during 12 minutes breast pump stimulation in five healthy, lactating, amenorrheic women on three occasions: ten to 90 days post partum, 180 one year partum. Baseline mean (+/- SEM) plasma similar the study periods. Mean stimulated increased periods (each P less than .001; baseline versus stimulated). Stimulated values significantly greater at (P .05; analysis variance). serum 61 +/- 9.5, 36 8.6, 33 10.8 ng/ml, respectively (not significant; one-way 71 8.1, 43 4.5, 2.8 significant). Thus, secretory reflex continues long-term lactation for first In addition, lactating produce a slight increase levels.
