THE CYCLICAL CHANGES IN THE UTERINE LYMPHATICS OF THE PIG. INVESTIGATIONS ON THE PERIMETRIUM*
Abstract
The orthograde demonstration and outlining of the uterine lymphatic system in the pig, during the sexual cycle was successfully achieved by the resorption of patent blue violet and Japanese ink.
During oestrus the lymphatics in the perimetrium are markedly widened and variable in size.
The subsequent phases of the cycle are characterized by a reticulate arrangement so that the preoestrus resembles the picture of oestrus.
The removal of the dyestuff takes place through the myometrium in a matter of seconds into larger vessels in the mesometrium which have a typical beaded appearance.
