摘要:
The present study was designed to test the existence of behavioral states in the fetus at term using simplified techniques. For this purpose simultaneous recording of the fetal heart activity by means of phonocardiotocography and of fetal body movements by means of real-time ultrasound was performed by using a multichannel recorded. The fetal heart activity was analyzed for two parameters: (1) long-term variability and (2) baseline accelerations. The fetal body movements were classified into three types. 880 min of recording time from 50 fetuses at 37–41 weeks of gestation were analyzed. Each segment of 1 and 3 min was classified into four distinct states, according to the combination of the above parameters. The segments that failed to fit into one of these states were labeled as ‘no state’. The frequency of each parameter was also independently calculated. The results were statistically analyzed by using a computer. The significance of the difference between the observed frequencies of the various states and their expected frequencies (obtained by the frequencies of the individual parameters) was calculated by the χ2 test. Behavioral states of a duration of 3 min were observed in 45.6% of the total periods recorded which is significantly higher (p < 0.001) than the 4.1% expected.

摘要:
Transvaginal ultrasonography was done on 26 pregnant women ranging from 5 to 27 weeks of gestation and 12 patients with gynecologic diseases. In early gestation, significant correlations were found among gestational age, crown-rump length, diameter of yolk sac and fetal heart rate. The maximal length of the gestational sac did not correlate with any other parameter. Transvaginal image quality was better in 76.2% in obstetric field and in 66.7 % in gynecologic field, as compared to findings with conventional abdominal ultrasonography, respectively. Fine structures and individual organs were better evidenced transvaginally. Therefore, transvaginal ultrasound affords pertinent information complementary to that obtained with the transabdominal technique.

摘要:
The present study was undertaken to examine the reliability of the sonographic diagnosis in 705 gynecological patients. The determination of the lesions was defined according to the operative diagnosis. The sensitivity, specificity and positive predictive value of the ultrasound technique were evaluated using the surgical findings as ‘gold standard’. In 631 patients (89.5%) the ultrasound examination established a correct diagnosis. The sensitivity and specificity of the ultrasound examination varied between 75–95.3% and 93.3–100%, respectively. The positive predictive value was found between 89.7 and 100%, while the false sonographic results were 10.4%, which included those of ectopic pregnancies. It is thus concluded that ultrasonography as compared to the surgical findings has proved to be of great value in establishing a gynecological diagnosis.

摘要:
This study was designed to explore the role of prolactin (PRL) in the modulation of follicular growth and steroidogenesis. An ovarian perifusion technique was used to determine the effect of PRL on steroid production by ovarian tissue. Immature female rats were injected with 5 IU pregnant mare’s serum gonadotropin to induce follicular maturation. After 40 h rats were killed, ovaries removed, and follicles dissected out. Follicles were divided into two groups (small, ≤ 4 mm; large, ≥ 5 mm in diameter), cut into fine fragments, and perifused for 6 h in the presence or absence of ovine PRL (100 or 1,000 ng/ml). In the group of small follicles, either of the PRL doses reduced the ability of follicular tissues to convert androgen to estrogen. HCG-induced production of progesterone by small follicles was also suppressed by higher doses of PRL. On the other hand, in the group of large follicles, PRL showed no effects on the aromatization and progesterone release by the follicular fragments. These results suggest that the small immature follicle is more sensitive to the inhibitory action of PRL on steroidogenesis and folliculogenesis. Thus it is possible that PRL may have a modulatory role in follicular growth and maturation and, consequently, in the selection of ovulatory follicle.

摘要:
The source of CA 125 in the sera of women is not known. Serum CA 125 concentrations were measured in 36 women with hypoestrogenic ovarian failure of whom 30 had hyper-(group A), 6 had hypo- or normogonado-tropic amenorrhea (group B). Group A consisted of 16 women with streak gonad syndrome, 6 with rudimentary ovary syndrome, 5 with premature menopause syndrome and 3 with gonadoblastoma. Serum CA 125 levels were normal in 34 patients irrespective of the presence of associated sex chromosome anomalies, and their mean values did not differ significantly from those of the 9 age-matched controls. We also measured normal CA 125 values in 2 females with müllerian agenesis. These data indicate that the derivatives of müllerian ducts do not contribute significantly to the presence of CA 125 in the sera of nonmenstruating adult women, and that the abnormalities of the X chromosome do not seem to influence CA 125 levels.

摘要:
A series of 23 punch biopsies proved to contain human papillomavirus (HPV) type 16 and with established clinical course (including HPV-NCIN, HPV-CIN I, and HPV-CIN II lesion), and 18 additional biopsies of HPV 6-, 11-, 16- or 18-induced genital lesions were analyzed immunohistochemically for expression of cytokeratin No. 19 polypeptide. An immunoperoxidase-ABC technique was used with a polyclonal antibody raised against a synthetic nonapeptide corresponding to the residues 2–10 of the NH2-end, non-alpha-helical region. This polyclonal cytokeratin No. 19 antibody stained mainly (but not exclusively) the basal cells of the normal exocervical epithelium (heterogeneous pattern). Basal cell staining was intense slightly more frequently in HPV-CIN than HPV-NCIN lesions, i.e., ++ or more in 14/24 (58.3%) versus 8/17 (47.0%), respectively. The difference was more marked in the staining of the superficial cells, 70.8 and 58.8% showing intense expression of cytokeratin No. 19, respectively. In 6 (21.4 %) of the 28 HPV 16 lesions, basal cell layer was intensely stained, as contrasted to none of the 13 HPV 6, 11 or 18 lesions. The most distinct feature was the well-defined granular staining pattern of the superficial layer in 8 out of 10 HPV 6/11 lesions, as contrasted to the homogeneous pattern in 24 out of 28 HPV-16-infected lesions. In superficial cells, regressed lesions exhibited intense staining in 9/13 (69.2%), as compared with only 4/10 (40%) of the progressed lesions. These deviations from the normal cytokeratin No. 19 expression pattern in cervical squamous epithelium might be associated with progression of the lesions from HPV-NCIN (usually of HPV 6/11 origin) into higher grades of HPV-CIN (usually caused by HPV 16).

摘要:
The antifungal effects of two commercially available spermicidal gels (Conceptrol, produced by Ortho Pharmaceutical, Raritan, N.J., and Koromex, produced by Schmid Laboratories, Little Falls, N.J.) as well as pure nonoxynol-9 and boric acid (both components of vaginal contraceptive products) were tested against 50 clinical yeast isolates by the agar dilution method. The formulated products exerted comparable dose-dependent inhibitory effects against all yeasts tested. A 3-fold dilution of the formulated spermicidal products inhibited 90% of the yeast strains tested. To determine if the antifungal effect was due to the spermicidal detergent nonoxynol-9, this compound was tested for antifungal activity but was completely ineffective against Candida albicans in concentrations up to 10%. Boric acid, present in at least one of the products (Koromex), inhibited representative yeasts at a concentration of 0.4%. The relationship of pH and oxygen tension to inhibition by the commercial spermicides was also investigated. The pH values tested ranged from 4 to 7 and had little effect on inhibition; anaerobiosis at pH 7 slightly reduced the inhibitory activity of Conceptrol gel.

摘要:
We used a combination assay of serum sialyl SSEA-1 antigen (SLX) and CA125 levels, and evaluated the clinical usefulness of this technique for a differential diagnosis of ovarian cancer, benign ovarian tumor and endometriosis. In 82 patients with ovarian tumors, the sera of 20 (64.5%) of 31 with ovarian cancer and 15 (48.4%) of the 31 with endometriosis (endometrial cyst) were positive for both SLX and CA125, but serum SLX level was 5 U/ml or less in these 14 SLX- and CA125-positive patients with endometriosis. The sera of 16 (80.0%) patients with benign ovarian tumor were negative for both tumor markers. The sera of 3 (9.7 %) of 31 with ovarian cancer and the sera of 2 (6.5%) of 31 with endometriosis were negative for both markers. The diagnostic accuracy (true positive rate × true negative rate) of the combination assay for ovarian cancer was 49.0% when the cutoff value of the serum SLX was 38 U/ml but improved to 78.5% when the value was set at 50 U/ml. When the cutoff value of serum SLX was set at 50 U/ml and that of serum CA125 at 35 U/ml, 27 of 37 patients who were positive only for CA125 had endometriosis. From the above observations, a combination assay of serum SLX and CA125 is a promising method for the differential diagnosis of malignant and benign ovarian tumors. Our results also suggest that to improve the diagnostic accuracy, the cutoff value of the serum SLX level should be 50 U/ml for ovarian tumors alone.
