摘要:

A rare type of cervical squamous cell carcinoma with pseudoglandular features occurred in a 22-year-old woman. Histological and ultrastructural characteristics of this tumor with keratinized cells as well as glandular mucin containing structures and intracellular luminal formations are presented. The problems associated with the diagnosis of cervical carcinoma in young women are discussed.

摘要:

The concentration of human placental lactogen (HPL), in serum was measured in venous and capillary blood from 31 pregnant women. 14 women had uncomplicated pregnancies. The others had complications including preeclampsia, intrauterine growth retardation, and severe edema. The correlation between values of HPL in venous and capillary blood was high. In all cases the clinical information obtained on placental function was the same, whether HPL was measured in venous or capillary blood. The day-to-day variability was of the same order for capillary as for venous samples. It is concluded that capillary blood may well be used for measurement of HPL in pregnant women. Capillary blood could replace venous blood for measurement of HPL in the supervision of pregnancies complicated by preeclampsia or intrauterine growth retardation.

摘要:

Amniotic fluids from women in West Virginia were evaluated for the presence of antibacterial activity by a bioassay technique. 41 % of 32 third trimester samples were inhibitory. Evaluation of additional test organisms emphasized differences in susceptibility of various bacterial strains; two isolates of Escherichia coli were found which were more sensitive to the phosphate-sensitive antibacterial system of amniotic fluid than in the initial test organism. The stated prevalence of inhibition may therefore be considered a conservative estimate.

摘要:

The alterations which occur in the total uterine blood flow (UBF) during early pregnancy in the guinea pig were determined using electromagnetic blood flow probes. Between days 4 and 6 postcoitum, UBF rose from basal levels of 1.2 ml/min to peak levels of 3.0 ml/min. The elevated levels corresponded temporally with the onset of blastocyst implantation. Between days 7 and 8, UBF declined to basal levels. In guinea pigs possessing three pregnancy sites per uterine horn on days 10–20, obvious regional differences in UBF were observed. Consistently higher UBF measurements were monitored from uterine segmental arteries supplying the tubal and cervical thirds of the uterus than from those distributed to the middle third of the uterus. These data indicate that regional variations in UBF exist in the guinea pig which may be involved in the regulation of pregnancy site selection or subsequent placental-fetal growth.

摘要:

In the present study the in vitro sensitivity to mitogens (phytohemagglutinin, PHA, concanavalin A, Con A) and purified protein derivative (PPD) antigen of lymphocytes of children exposed in utero to short-term (n = 7) or long-term (over the whole pregnancy, n = 9) action of synthetic glucocorticoids was evaluated. Blood samples from these children and their age- and sex-matched controls were collected 3–4 and 3–10 years after delivery in the short-term and long-term exposure groups, respectively. After short-and long-term exposure to glucocorticoids the counts of all lymphocytes and alpha-naph-thyl-acetate-esterase-positive lymphocytes in the peripheral blood, and the responses of T lymphocytes to mitogens or PPD antigen were similar in the subjects and their controls. The present data thus provide additional evidence of the safety of prenatal glucocorticoid prophylaxis for respiratory distress syndrome. Fetal lymphocytes also seem to be resistant to the extended action of exogenous glucocorticoids.
