[Lymph outflow pathways from the uterus and its regional lymph nodes in the rat at various stages of pregnancy].
From the body of the rat uterus, the lymph outflows into the caudal lymph nodes and when the latter are absent--into the iliac lymph nodes. From the medial and middle parts of the uterine horn the lymph out flows into the iliac lymph nodes, and from the lateral part of the uterine horn--into the renal lymph nodes. Some parts of the lymph outflows into corresponding contralateral lymph nodes. If the mass of the caudal lymph nodes in pregnant animals does not significantly differ from those in nonpregnant animals, the mass of the iliac and renal nodes increases with pregnancy. Maximal increase of the iliac and renal lymph nodes mass coincides with completion of the alantoic placenta formation. It is probable that there is a positive correlative dependence between the number of embryos in the uterus and the mass both of the iliac and renal lymph nodes.
