[Morphology and development of blood vessels of the fallopian tubes of cattle in the fetal and neonatal periods].
The experiments on morphology and development of oviduct arteries and veins in cattle have been carried out on 79 specimens that is on 68 fetuses from 9-40 weeks of pregnancy and on 11 newborn animals at the age of 1-14 days. The age of fetuses has been determined by Kantorova method supplemented by the methods of other authors. The conducted experiments have been made by means of microanatomical method using rubber latex which was forced into the vessels being under observation by means of automatic injection set constructed by one of the authors. The preparation of the tested arteries and veins has been done by anatomical needles and arrows under stereoscopic microscope using magnification of 3-25 times depending on the needs. The conducted experiments have been recapitulated by the following conclusions and generalizations: 1. Except for the youngest fetuses oviduct of fetuses and new-born animals is vascularized mainly by uterine branch and tubal branch or tubo-ovarian branch of ovarian artery and ovarian vein. Besides blood supply of this organ is periodically complemented by the following vessels: accessory tubal branch of artery and ovarian vein, accessory tubal branch of arterial and venous plexus of ovary, and accessory tubal branch of uterine artery. 2. In the course of the fetus development the examined vessels undergo a number of qualitative and quantitative transformations of which the rate is especially high in the first weeks of the fetus development; the quantitative transformations are divided into the progressive and regressive changes, manifested first by the origination and then by atrophy of majority of accessory tubal vessels from which the vein transformations get ahead of the artery transformations. 3. Finally the oviduct in new-born animals is vascularized by two main branches of artery and ovarian vein--tubal branch and uterine branch and in approximately 20% of examined specimens--accessory tubal branch of artery and venous plexus of ovary.
