Abstract

A study of serum calcium, phosphorus and glucose levels in mother and newborn infant was carried on 28 mother/baby pairs who were admitted to Chosun University Hospital from May 1974 through Oct. 1974. Following results were obtained. 1. The mean value of serum calcium in labor was 9. 16±0. 25mg% and that of cord blood was 10. 26±0. 29mg. Calium was found to be significantly highr (by 1.10 mg%) in cord blood than in maternal blood. The difference of calcium level between mother in labor and that of cord blood was statistically significant. (p<0. 01) Maternal level of calcium during labor influenced positively the level in cord blood. 2.The mean value of phosphorus in labor was 3.12±0.13 mg^ and that of cord blood was 4.05+0.12 mg%. ’As in case of calcium, phosphorus was found to be significantly higher (by0. 93 mg%) in cord blood than in maternal blood. The difference of phosphorus level betweenmother in labor and that of cord blood was statistically significant. (p<0. 01)Maternal level of phosphorus during labor infuenced strong positively than the level in. cord blood. Incrased demands by growing fetus on maternal calcium and phosohorus may explain the subnormal calcium and phosphorous levels in mother in labor. 3.The mean value of glucose in labor was 114. 8±3. 87 mg% and that of cord was 98. 3± 4.40 mg%. There was a significantly lower level (by 16. 5 mg%) in cord bood than in maternal blood. The difference of glucose level between mother in labor and that of cord blood was statistically significant. (p<0. 01) The fetal glucose level Was substantially lower than the maternal blood concentration, this fact can be easily explained by assuming that fetal glucose uptake requires the existence of a large transplacental gradient.
