Objective To investigate bone nutritional status of neonates and their mothers as well as the correlation between them by estimating the concentrations of 25-D3, calcium and phosphorus in maternal blood and cord blood at birth, and by measuring the bone speed of sound of neonates and their mothers with quantitative ultrasound within 3 days after birth. Methods The concentrations of 25-D3, calcium and phosphorus in the serum were estimated both from 32 pregnant women who had a term delivery and from the umbilical cord at birth.

Oxalic acid loading substantially stimulated soil P release from A1 horizon, showing a linear relationship; but its effect on B horizon soil was relatively negligible, especially at low oxalic acid concentrations mmol L^(-1. Oxalate solutions 0.5~20.0 mmol L^(-1 oxalic acid adjusted to pH 5.16 with 10.0 mmol L^(-1) NaOH had a much higher (1.51~2.98 times) soil-P-release effect than oxalic acid solution the same in oxalate concentration. Therefore, the mechanism of oxalic acid/oxalate triggering release of soil phosphorus is assumed to be dominated by ligand-exchange or complexing reactions of oxalate anionC2O(superscript 2- subscript 4 but not simply acid-dissolving effect. The effect of oxalate anion on soil phosphorus release was found to be somewhat cumulative, i.e. the amount of P released was primarily controlled by the cumulative oxalate loading rate, relatively independent of the manner of oxalate addition (one-time or sequential).
