摘要
The effects of a diet deficient in magnesium (0.022% Mg) on the bioavailability of dietary Ca and phosphorus were studied in Wistar rats after 1, 5, 6, 7, 8, 9 and 10 weeks. Feeding with a diet deficient in Mg significantly increased Ca absorption and balance from the first week until the end of the experimental period, and increased phosphorus absorbed in weeks 9 and 10. However, phosphorus balance became negative in first week of study, as a result of phosphaturia.
