title: The disappearance of the foetal suppressor cell activity in newborn rats.
abstract: The suppressor splenocyte activity in newborn rats was studied using an intrarenal test of the local graft versus host reaction in the xenogenous rat-mouse system. It was demonstrated that the suppressor splenocyte activity in newborn rats born from both physiological and hormonally or mechanically prolonged pregnancy terminates within 2 days after birth. On the other hand, in newborn rats born from shortened pregnancy the suppressor splenocyte activity persists for 3 days.
