Abstract
The concentration of secretory IgA was measured in human colostrum from 129 mothers who “normally” delivered after full-term pregnancy. The relations between the concentrations of secretory IgA and many stress conditions during delivery, physical conditions, stress sensitivities, and mother's character were investigated. Minimum and maximum values of secretory IgA concentration were 13mg/dl and 5860mg/dl respectively. Mean and median values was 1223mg/dl and 621mg/dl respectively. A wide variation of secretory IgA concentration among individuals was noted in human colostrum of 3 days postpartum.
A significantly higher value of secretory IgA concentration in colostrum was observed among mothers who are more sensitive to stress, unstable in character and receivedmore physical stresses during delivery when compared with mothers who are less sensitive to stress, stable in character and received less physical stresses during delivery.
