Microsurgical nonvascularized transplantation of a 1-cm segment of fallopian tube was performed using the rabbit as a model. Autograft experiments showed survival of a 1-cm tubal segment for as long as 10 months postoperatively. Allografts survived equally as well, and one rabbit became pregnant.
The membrane activity recorded from the circular muscle layer of the human Fallopian tube showed a unique pattern (slow potential changes), yet the hormonal and adrenergic influences appeared to be much the same as observed in he myometrium. Differences in electrical and mechanical activities, and also the sensitivity to catecholamines during the secretory or proliferative period were elucidated.
PURPOSE: In an effort to reduce patient radiation dose during selective fallopian tube catheterization, the diagnostic adequacy of fluoroscopic images was compared with digital radiographic images in both a phantom study and a clinical study. METHODS: For the phantom study polyethylene tubes with inner diameters of 1.30, 0.95, 0.80, 0.57, and 0.45 mm were used. Randomly selected tubes with/without stenoses, recorded by digital radiographic and last-image hold fluoroscopic images, were presented to five blinded radiologists, and receiver-operating characteristic (ROC) analyses were performed. For the clinical study tubal visualization as well as detectability of stenoses and occlusions were analyzed in 14 women using a 2-way analysis of variance for nonrepeated measures. RESULTS: The phantom study showed no significant differences between the two imaging techniques for 0.57-mm-diameter and larger tubes; in contrast, fluoroscopic images provided significantly lower detectability of stenoses in 0.45-mm-diameter tubes (p < 0.05). The clinical study showed inferior tubal visualization and diagnostic performance for fluoroscopic images. CONCLUSIONS: Although fluoroscopic images have inferior diagnostic capability in detection of tubal stenoses and occlusions, these images may be adequate for documenting tubal patency with spill into the peritoneal cavity.

The clinicopathologic aspects of seven cases of Fallopian tube adenocarcinoma are analyzed. Potential early spread of this malignancy to the retroperitoneal lymph nodes and right subdiaphragmatic area is documented. Multimodality treatment of tubal cancer to include surgery, radiation, and drug therapy (alkylating agents, progestins, with or without 5-fluorouracil and adriamycin) appears feasible and promising.
An extremely rare case of partial hydatidiform mole located in the right Fallopian tube was diagnosed by ultrasonography and computed tomography. The lesion was excised, and the human chorionic gonadotropin (HCG) level in early morning urine fell below 1,000 IU/ml on postoperative day 11, and the serum HCG-beta level normalized on postoperative day 46.
Three patients with the primary carcinoma of the fallopian tube, aged 51, 68, and 42, are presented. The disease was diagnosed in the period from 1971 to 1980. In all three patients there was a triad of symptoms: bleeding, adnexal tumour, and pain, but the diagnosis was made only during surgery. The operative therapy with consecutive radiation was applied in all three patients.
The acrosome reaction (AR), a modified exocytotic process, is prerequisite for successful mammalian fertilization. The protein component that is responsible for the AR-inducing activity of human follicular fluid, has been found to be immunologically identical with corticosteroid-binding globulin (CBG), which is well characterized and serves as a transport protein for progesterone and cortisol in the plasma. Our findings have shown that the CBG-like protein is expressed by endothelial cells of the Fallopian tube depending on the hormonal cycle. In the culture medium of human epithelial tubal cells, the CBG-like protein was detected by Western blot analysis. The protein was also found in biologically active form in human tubular fluid. Our investigations strongly indicate that human Fallopian tube cells actively express and secrete a CBG-like progesterone-binding protein, which might play a role in the in vivo modulation of human sperm AR.
In human cervical epithelium and uterine endometrium, globo-series neutral glycosphingolipids with N-alpha-hydroxy fatty acyl phytosphingosine (4-D-hydroxysphinganine) as the ceramide and sulfatide (I3SO3-GalCer), which were contained in trace amount at the follicular phase, significantly increased in concentration at the luteal phase, comprising about 20% of the individual neutral glycosphingolipids and about 15% of the total acidic glycosphingolipids, respectively. However, in the mucosa of fallopian tube, neutral glycosphingolipids with the same polarity as those in the cervical epithelium and uterine endometrium at the luteal phase and sulfatide remained at a constant and higher level independently of the menstrual cycle. The structures of neutral glycosphingolipids in the fallopian tube, having the same polarity as that of N-alpha-hydroxy fatty acyl phytosphingosine-containing molecules appeared in the cervical epithelium and uterine endometrium at the luteal phase, were determined to be N-alpha-hydroxy palmitoyl 4-sphingenine-containing ones by negative-ion FABMS. Also, laminin, but not collagen type IV, was found to be contained in the concentration correlated well with that of sulfatide in the genital tract, when determined by western blotting with monoclonal anti-laminin and anti-collagen type IV antibodies, indicating a possible function of sulfatide as a receptor for laminin in the human female genital tract.

OBJECTIVE: The authors demonstrate the case of left adnexal torsion caused by 2 benign teratomas in its ovarian and tubal location. DESIGN: Case report. SETTING: Department of Obstetrics and Gynecology, 1st Faculty of Medicine and General Teaching Hospital, Charles University, Prague. CASE: 24-years old woman underwent laparoscopy for several days lasting pain in lower abdomen and ultrasound finding of semicystic mass in the left adnexal region with suspicion of teratoma. The benign teratoma of the left ovary together with a torsion of the left Fallopian tube distended by teratoma was revealed during surgery. Left side salpingectomy and enucleation of the ovarian teratoma has been performed. This surprising finding was confirmed by histopathological examination. CONCLUSION: The acute gynaecological torsion event may be caused not only by torsion of uterine fibroid or enlarged tumorous ovary but rarely also by a teratoma of the Fallopian tube.
The cancer of the fallopian tube is one of the most rare malignant diseases of the female genital tract. The authors present a case of a 66-year old women, that was difficult for diagnosis and interpretation of the clinical appearance and the results of biopsic curettage. The discussion of the case is accompanied by a literature review for the last five years concerning diagnosis, prognosis and treatment of this rare disease.

Primary fallopian tube carcinoma is an aggressive but rare tumor. This is an unusual presentation of papilliferous tubal carcinoma presenting with vaginal discharge through a large sinus approximately 2-3 cm in size, located posterior to the neck of cervix. Surgery was undertaken with the initial diagnosis of primary ovarian carcinoma and the fistula was left to heal spontaneously. Surgical resection was followed by adjuvant chemotherapy. The patient is doing well after the therapy.
The localization of Thy-1, MRC OX 2 and Ia antigens as defined by monoclonal antibodies MRC OX 7, MRC OX 2 and MRC OX 6 was determined by an indirect immunoperoxidase technique on cryostat sections of rat ovaries. Thy-1 antigen was present significantly in the theca interna of growing antral follicles. Developing corpora lutea exhibited an increasing presence of Thy-1 antigen and it was still present in degenerating ones. Thy-1 antigen was constantly present in fallopian tube tunica propria. The MRC OX 2 antigen was expressed most on ovarian structures that do not develop further, i.e. granulosa of degenerating antral follicles and third generation of corpora lutea. MRC OX 2 antibody stained the capillaries of the fallopian tube; the most heavily MRC OX 2+ were the cells of ovarian germinal epithelium. The Ia+ cells were occasionally found within the growing ovarian structures but they were more frequent in degenerating ones. Rare or no la+ cells within the ovary and heavily Ia-depleted thymus medulla and Ia areas in the spleen were, however, observed in some rats. The role of these antigens with respect to the structures they label is discussed.
OBJECTIVE: To study the histopathological effects of silicone rubber on the human fallopian tube. METHODS: A prospective longitudinal study at Benha University Hospital and Boulak Eldakrour General Hospital, Egypt. Nine patients who were on the waiting list for hysterectomy and requested postponing of their operation for personal reasons. RESULTS: Our results suggest that silicone rubber induces histopathological changes in the form of ciliary loss and intracellular changes. CONCLUSIONS: These effects tend to increase with the increase of the duration of tubal plugging and are best seen by electron microscopy.
Organ cultures of human Fallopian tubes were infected with Mycoplasma hominis. Scanning and transmission electron microscopy revealed swelling of the cilia of the tubal epithelial cells in infected cultures. In some, the entire cilia were swollen; in others, only the tips. Uninfected cultures kept for up to 7 days showed no structural changes in the cilia or other surface structures. M. hominis multiplied in organ cultures, but not in culture medium without tissue. A practical organ culture technique for the preparation of specimens for electron microscopy is described.
