Functional and immunologic protein S levels are decreased during pregnancy.
Protein S, is a natural anticoagulant protein which serves as a cofactor for activated protein C. During pregnancy and in the postpartum period, functional protein S levels are significantly reduced (38% +/- 17.3%, mean +/- 1 SD) when compared to nonpregnant females (97% +/- 31.6%) (P less than 0.001). In plasma an equilibrium exists between functionally active free protein S and protein S comp...
متن کاملImmunity during pregnancy: lymphocyte subpopulations and mitogen responsiveness.
Many hypotheses have been proposed to explain the alteration of maternal immune status that allows the fetus to escape rejection. Published data using monoclonal antibodies have stated that there are small variable reductions in circulating T-lymphocytes and little or no change in helper-to-suppressor ratios. Specific decreased levels of helper T-cells have been claimed by other workers. Our la...
متن کاملDiminished maternal responsiveness during pregnancy in multiparous female common marmosets.
Common marmoset monkeys (Callithrix jacchus) live in small groups in which, usually, only a single female breeds and all group members provide infant care. When two females breed concurrently, however, they may commonly kill one another's infants, especially during the peripartum period. To investigate the mechanisms underlying infanticide by breeding females, we characterized responses of mult...
متن کاملImmunologic responsiveness and the induction of experimental neoplasms.
of polyoma virus. Age susceptibility to the oncogenic effects of virus was extended to the adult period. The usual stigmata associated with thymectomy at birth were not observed in the 3-day thymectomized mice. Nevertheless the methods used to restore immunologically deficient neonates were also effective in restoring the capacity to resist tumor induction by polyoma virus. Growth curves of pol...
متن کاملVentilatory responsiveness to progressive asphyxia during sleep in newborn lambs: effects of maternal anemia during pregnancy.
Our aim was to determine the effects of intrauterine compromise, induced by maternal anemia, on ventilatory responsiveness of the sleeping newborn to progressive asphyxia. We induced anemia in 6 sheep for the final third of pregnancy and studied their offspring for 2-3 weeks after birth. Lambs from anemic ewes were growth-restricted at birth; they and 6 control lambs were chronically instrument...
