Abstract: Seven items of serum idices related to calcium regulation were measured in 145 normal pregnant women (with different gestation periods and at postpartum stage), 90 cases with moderate and severe PIH and non pregnant women.Some of them were given calcium supplement from 2nd trimester to term.Serum calcium,phosphorus,alkaline phosphatase,thyroxine calcitonin,D3[25(OH)D3],and osteocalcin were measured in 1st,2nd,3rd trimester and after delivery. PIH morbidities were compared between calcium supplement and no supplement .Results showed that each index was increased with the increase in gestation week and at postpartum stage in normal pregnancy, but not in PIH.Calcium supplement in 2nd trimester reduced the PIH morbidity significantly.Calcium deficiency could increase PIH morbility and calicium supplement from 2nd trimester could reduce the PIH morbidity.

Key words: calcium-regulating factors, pregnency, PIH
