Abstract:
Significant changes in saturable and non-saturable intestinal calcium uptake processes occur during development of the rat. A modified 'free floating disc' assay was used to measure total, active and passive duodenal calcium uptake on matching duodenal segments from male Sprague Dawley rats aged 14 to 56 days of age. The results were compared and found to give patterns similar to data published for the in situ ligated loop technique.
