Abstract
By stepwise regression analysis the levels of the alkaline phosphatases in maternal serum and in cord serum were studied in relation to each other and to 19 other factors. The maternal serum heat-stable alkaline phosphatase level was found to be influenced by the alkaline phosphatase level in placental tissue, the placental alkaline phosphatase factor I1 and the maternal serum acid phosphatase level. The maternal serum heat-sensitive alkaline phosphatase level was found to be influenced by the maternal serum acid phosphatase level, the cord serum alkaline phosphatase level, the number of previous deliveries and the birth weight. The two last-mentioned regression estimates were negative. The cord serum alkaline phosphatase level was found to be influenced by the maternal serum heat-sensitive alkaline phosphatase level, the cord serum acid phosphatase level, the maternal age and the sex of the infant. The following factors showed no statistically significant effects on the maternal and cord serum alkaline phosphatase levels: the placental alkaline phosphatase factors F1 and S1 the haptoglobin groups, the ABO blood groups of mother and infant, the maternal Rh blood group, the pregnancy zone protein, the placental weight, the gestation length and the number of previous abortions.
