calcium excretion
4.Method Serums parathyroid hormone (PTH),calcitonin(CT),25 hydroxycholecalciferol D 3(25(OH)D 3),cyclic adenosine monophosphate (cAMP) and serums calcium( Ca),phosphorus(P),magnesium(Mg)and urinary Ca,P, Mg and glycosylated hemoglobin(HbAlc),24 hour urinary glucose excretion and 60 type 2 diabetic patients were mearsured.
5.Methods Serum parathyroid hormone(PTH)、 calcitonin (CT)、25 hydroxycholecalciferol〔25(OH)D 3〕、cyclic adenosine monophosphate(cAMP) and serum calcium (Ca)、phosphorus(P)、magnesium (Mg) and urinary Ca、P、Mg and glycosylated hemoglobin (HbA1c), and 24 hour urinary glucose excretion were mearsured in 20 healthy subjects and 60 type 2 diabetic patients.
6.All ducklings were fed with the basic diet consisting mainly of corn-soybean meal,but for the experiment group 400 u/kg phytase was added to the diet in order to study its effect on the production performance, the content of calcium and phosphorus in tissues of tibia and serum, the activity of alkaline phosphatase (ALP)in serum and the utilization ratio of Ca, P, and the excretion of phosphorus in feces.
