摘要:

Ovaries from homozygous diabetic (db/db) female mice were removed and transplanted into the empty left ovarian sacs of normal homozygous (m/m) female mice which had undergone left oophorectomies. To produce controls, the previously removed normal left ovaries were transplanted into the empty left ovarian sacs of other normal (m/m) left oophorectomized females. Glucose tolerance tests were done on the study and control mice before surgery, after surgery, during pregnancy, and after delivery. There were no significant differences in the glucose tolerance test results between study group and controls before or after surgery. However, the study group, when compared to the controls, had a statistically significant glucose intolerance during pregnancy. After delivery, the glucose levels returned to normal. The ovaries from diabetic (db/db) female mice may produce hormones which, by themselves or in concert with the fetal and placental hormones, may produce maternal glucose intolerance during pregnancy.

摘要:

The concentrations of 24 amino acids and four other related compounds were determined in extracts of biopsy specimens from myometrium and musculus rectus abdominis of 10 healthy term pregnant women during elective cesarean sections. The total free amino acid pool did not differ significantly between the two muscle types. There was a myometrial abundance of the two anionic amino acids glutamate and aspartate and the two aromatic amino acids tyrosine and phenylalanine, but most neutral and cationic amino acids in striated skeletal muscle tissue were found in excess of those in uterine muscle tissue.

摘要:

Fibronectin can be detected in the plasma and the extracellular matrix of the uterus of pregnant women. Studies so far have compared individual observations, whilst serial investigations during pregnancy, and during and after parturition have not been carried out. Plasma fibronectin levels were measured in 153 women with healthy pregnancies in relation to the gestational age. During parturition, blood was taken from the inception of labor through to parturition, and on the 1st, 3rd, and 5th days after parturition. The investigations of the plasma fibronectin level in pregnant women show constant concentrations up to the 35th week of pregnancy. From the 36th week onward the fibronectin rises significantly before dropping to the initial values at the start of labor. The elevated fibronectin concentration in the last 4 weeks before delivery could be explained both by renewed, elevated synthesis in the uterus and placenta as well as by lower consumption. The decline in the fibronectin level with the onset of labor could be caused by an elevated enzymatic induction in the uteroplacental unit in connection with the start of parturition.

摘要:

Prevalence and determinants of long-term psychosocial morbidity among women giving birth to a stillborn child are largely unknown. Few, if any, systematic epidemiologic studies are available. In this pilot study we investigated one alternative way to collect data from relevant patient populations and formulated some hypotheses. Moreover, questions found unhelpful in this context were identified, e.g., whether the mother had bathed her dead child or not. Fruitful hypotheses found worthwhile testing were, among others: the risk of long-term anxiety-related symptoms is reduced if (1) the woman has seen her stillborn child, (2) she has an ultrasonic or photographic picture of the child, and (3) she has gone through a ritual, primarily burial of the child; moreover, (4) divorce may be a social consequence of the intrauterine loss of a child.

摘要:

The present study was undertaken to compare adhesion formation and reproductive outcome after reproductive surgery with or without the application of fibrin sealant. At laparotomy, the ovaries and uterine horns of 20 rabbits were longitudinally incised on the antimesenteric side using a monopolar microneedle. At random, one ovary and the ipsilateral uterine horn were covered with fibrin sealant, while those on the contralateral side were left uncovered without application of sutures. The rabbits were then mated, and 2 weeks later a second-look laparotomy was performed by a blinded observer. No statistically significant differences were found in postoperative adhesions, number of corpora lutea in each ovary, number of embryos in the ipsilateral uterine horn, and nidation index for each side. Fibrin sealant for conservative surgery does not appear to significantly affect either postoperative adhesion formation or reproductive outcome.

摘要:

To assess the usefulness of fat-saturated magnetic resonance (MR) imaging in detecting small endometrial implants, 258 pigmented lesions of endometriosis from 80 consecutive patients with histophatologically diagnosed pelvic endometriosis were compared using fat-saturated and conventional MR imaging. MR imaging was performed with a 1.5-tesla superconducting magnet with spin echo T1-, T2-, and fat-saturated T1-weighted images. Both conventional MR images and fat-saturated MR images permitted identification of almost all endometriomas > 10 mm in diameter. With conventional MR imaging, 29 endometrial implants measuring < 10mm in diameter were detected. One hundred and seven lesions were detected by fat-saturated MR imaging. However, conventional MR images demonstrated only 4 lesions among these Ill small endometrial implants that measured < 5 mm in diameter. The addition of fat-saturated MR imaging increased the detection rate to 55 of Ill lesions. Fat-saturated MR imaging can, therefore, be useful in detecting small endometrial implants.
