Changes in plasma inorganic phosphate associated with endocrine activity in Xenopus laevis

Author: Schrire, Velva Date: 1940 The plasma inorganic phosphate level may be influenced by (1) factors affecting the intermediary metabolism of phosphorus, (2) alternation in the degree of absorption of phosphorus, (3) alteration in the degree of excretion of phosphorus. In ... Read more
