Results of preliminary investigations of fallopian tube patency in cattle using a method based on intrauterine instillation of PSP dye, and detection of the dye in the urine, suggest that this test can provide a useful diagnostic aid in cases of bilateral occlusion. In such cases PSP dye is not evident in the urine two hours later. In normal animals dye is present within 30 minutes. In two animals with unilateral blockage dye appeared at an intermediate time between the normal and bilaterally occluded cases. Repetition of the test and the use of adequate volumes of dye to cause uterine distension may be necessary to eliminate false negatives.

Lymphoid tissue of the human fallopian tube consists of follicles, lymphoepithelium, and lymphatic and blood capillaries and is located consistently in the interstitial part of the human fallopian tube. Using an immunoelectronmicroscopic technique, we have elucidated the ultrastructure of the lymphoid tissue of the human fallopian tube and the fine distribution and ultrastructure of the lymphatics associated with the rabbit fallopian tube. Lymphatic capillaries arise in the lamina propria mucosa and the periphery of follicles, where they are sparsely distributed, run through the muscular layer, and form a dense network in the subserosa. Characteristic features of the ultrastructure are aggregations of smooth muscle cells, alternating areas of densely and sparsely distributed collagen fibers, and unmyelinated nerve fibers beneath the lymphatic endothelium. Immunoelectronmicroscopic analysis has demonstrated an obvious difference in the distribution of T- and B-lymphocytes in the lymphoid tissue of the human fallopian tube. Many T-lymphocytes are present in the follicles and epithelium, but B-lymphocytes are either absent or rarely found. T-lymphocytes sometimes infiltrate into the basal lamina of the epithelium lying in close contact with the follicles. We conclude that the lymphoid tissue is constantly located in the interstitial part of the human fallopian tube and that intraepithelial lymphocytes, mainly T-lymphocytes, migrate via the basal lamina of the epithelium from follicles. Lymphatic capillaries in the fallopian tube may be the main migratory route of intraepithelial lymphocytes. The intraepithelial lymphocytes and epithelial cells of the fallopian tube have attracted considerable interest as a result of immunological studies of the recognition of spermatozoal antigens and the fertilized ovum.(ABSTRACT TRUNCATED AT 250 WORDS)

Prenatal development of ciliated cells in the human fallopian tube was studied by light and electron microscopy in specimens obtained from 12 fetuses, aged 12-40 weeks. On light microscopy, transverse sections of the ampullary portion of the tube revealed a slit-like lumen at 12 weeks. The lumen began to fold by 15 weeks, and formed the typical villous structures by 31 weeks. On electron microscopy, the epithelial cells contained a large number of sub- and supranuclear glycogen particles until 18 weeks and an occasional solitary cilium. At 20-22 weeks, instead of glycogen particles, cytoplasmic organelles such as mitochondria, rough endoplasmic reticula and Golgi apparatus were well developed, and some cells possessed cilia with a 9 + 2 microtubular structure. Between 22 and 31 weeks, ciliated cells were sporadically observed. At 31 weeks, the epithelial cells accumulated a large number of sub- and supranuclear glycogen particles. Afterwards, numerous ciliated cells with well-developed cytoplasmic organelles were observed by 40 weeks.
