  • Title: Investigations on erythropoiesis in newborn rats. Dependence of erythropoiesis in newborn rats on the intensity of the haemopoietic processes in the lactating mothers.
    Author: Dusza L.
    Journal: Acta Physiol Pol; 1975; 26(4):367-76. PubMed ID: 1199744.
    Abstract:
    The intensity of haemopoietic processes was investigated in 7, 9, 11, 14 and 19-day-old suckling rats in relation to the intensity of these processes in their mothers. The rate of the haemopoietic processes in newborn rats was determined on the basis of 59Fe incorporation into the blood and haemopoietic organs. The activity of the erythropoietic system in lactating rat females was stimulated by haemorrhage and inhibited by erythrocyte transfusion. Anaemization of lactating rats by haemorrhage did not stimulate erythropoiesis in the suckling rats. Posttransfusion polycythaemia in the lactating mothers inhibited erythropoiesis in the suckling rats beginning with the 9th day of life. This phenomenon became more pronounced with the age of the rats.
