[Silicon concentrations in maternal serum and breast milk in the postpartum period].
The silicon (Si) concentrations in maternal serum and breast milk were determined for 38 healthy postpartal women, 19 primiparae and 19 multiparae, by using inductively coupled plasma-atomic emission spectrometry (ICP-AES). The results are as follows: 1. The geometric mean (95% confidence interval) of the Si level in maternal serum was 9.7 mumol/l (8.8-10.8 mumol/l) at 1 week after delivery, and 8.1 mumol/l (7.1-9.2 mumol/l) at 1 month after delivery. The Si level at 1 week after delivery was significantly (p less than 0.05) higher than that at 1 month after delivery. 2. The geometric mean of the Si level (95% confidence interval), in breast milk was 6.3 mumol/l (5.4-7.3 mumol/l) at 1 week after delivery, and 6.1 mumol/l (5.1-7.2 mumol/l) at 1 month after delivery. 3. At both 1 week and 1 month after delivery, a significant correlation was not found between the Si concentrations in maternal serum and in breast milk.
