66.下列何者不是parathyroid hormone之作用？
A.作用於肝臟以保留鈣質
B.刺激calcitriol生成
C.增加鈣質吸收
D.刺激骨形成
答: A
解析： Endogenous parathyroid hormone (PTH) regulates the level of calcium in the blood. Even a small decrease in calcium will cause secretion of PTH. It acts on the kidneys to conserve calcium and stimulate the production of calcitriol, which increases the absorption of calcium. PTH stimulates bone formation and bone resorption, but also increases the movement of calcium from the bone to the blood.
答案A應為作用於腎臟以保留鈣質
