PTH

A parathormone (PTH) assay reveals a high normal to elevated level of PTH.

素(PTH)测定显示PTH升高。

Tetany, epilepsy, neuro-psychiatrical symptoms, hypocalcemia, hyperphosphatemia were common clinical manifestation.There was also low level of PTH, except pseudohypoparathyroidism.

临床表现为手足抽搐、癫痫发作、精神症、血钙降低、血磷升高、除假性减外血PTH均降低。

These results suggest that early neonatal hopocalcemia appears to be related to a transient lack of response to PTH of the target organs, disordered vitamin D metabolism and hypercalcitoninemia.

由上述结推论新生儿之血钙调节是由多种因素共同参与，而导致新生儿低血钙症之重要因素，包括暂时性肾小管细胞对副素之低反应及维生素D代谢上之障碍。
