Serum calcium inorganic phosphorus, protein and alkaline phosphatase as well as urine calcium were studied in fifty-five primigravid Nigerian women during pregnancy and postnatal period. Each patient was seen at the various stages of pregnancy and thus acted as her own control. Serum calcium levels fell with progressing pregnancy. Urine calcium showed a highly significant decrease throughout pregnancy and in the puerperium. Alkaline phosphatase showed a continuous rise with advancing gestation which was statistically highly significant, with a return towards normal values in the postnatal period. Serum inorganic phosphorus showed no significant alteration right through the pregnancy period. The normoproteinaemia seen in the group studied suggests that albumin did not make any contribution to the fall in the serum calcium levels seen during the study.
对55名尼日利亚初产妇在孕期和产后的血清无机钙、无机磷、蛋白质、碱性磷酸酶以及尿钙进行了研究。每位患者在孕期的各个阶段均接受检查，因此其自身可作为对照。血清钙水平随孕周增加而下降。整个孕期及产褥期尿钙均显著降低。碱性磷酸酶随孕周增加持续升高，具有统计学高度显著性，产后恢复至正常水平。整个孕期血清无机磷无显著变化。研究组中出现的正常蛋白血症表明，白蛋白对研究期间血清钙水平的下降没有任何影响。
