Calcium Glycerophosphate
To study the efficacy of calcium glycerophosphate (CaGlyP) over conventional mineral salts of calcium gluconate were more than KH2PO4 + K2HPO4 (CaGluc + P) in promoting mineral retention, mineral 72 hours, status Biochemical net acid excretion and the case of assessed growth 16 low birth infants (TPN) received total parenteral nutrition with about 1.5 mmol Ca and P.kg-1d-1 for 5 d. Calcium retention (1.2 +/- 0.2 vs 1.0 +/- 0.2 mmol.kg-1d-1, mean +/- SD) and phosphorus (1.1 +/- 0, 3 vs 0.8 +/- 0.3 mmol.kg-1.d-1) of CaGluc + P against CaGlyP were similar, as were magnesium and sodium retention, urinary pH and net excretion of 'acid. Plasma ionized calcium, inorganic phosphorus, alkaline phosphatase, and osteocalcin were normal and did not differ between groups. CaGlyP is as effective as CaGluc + P in promoting mineral retention and normal mineral homeostasis. With a binding less than or equal to 1.5 mol of Ca and P.kg-1j-1, or mineral salt retention are only 60% and 45% of the predicted intra-uterine accumulation of calcium and phosphorus. Large entries, which are approved by the more soluble CaGlyP, may be desirable for infants who have received TPN.
