Calcium transport across the chick small intestine as facilitated by Vitamin D.

The work reported in this thesis is mainly concerned with the influence of vitamin D on the subcellular distribution of calcium in the duodenum mucosal cell of the domestic fowl. The work is introduced by resume on a number of topics related to and that play a role in calcium metabolism in the body. Specific emphasis has been given to the recent discoveries of the metabolism of vitamin D and identification of calcium binding protein. The remainder of the thesis is divided into seven chapters which deal with experimental methods, experimental results and the final conclusions of these results as proposed in a model. for calcium transport across the mucosal cell
