Prostaglandins and the myometrium and cervix

Prostaglandins, Leukotrienes and Essential Fatty Acids, 2004
Prostaglandins have long been thought to play important roles in the mechanism of parturition. Here we review the involvement of prostaglandins in myometrial and cervical functions with emphasis on human labor and birth. In addition, the cellular sources of prostaglandins as well as their interactions with various other endocrine, paracrine and ...

Arteriovenous shunts in the myometrium

American Journal of Obstetrics and Gynecology, 1956
Abstract Arteriovenous shunts were found in the muscular portion of 16 of 25 surgically removed uteri. These shunts were demonstrated by plastic casts of the vessels obtained by injecting arteries and veins with vinyl acetate of different colors. Glass spheres with a diameter many times that of capillaries passed from arteries into veins with the ...

Electrolyte in human myometrium

American Journal of Obstetrics and Gynecology, 1960
Abstract 1. 1. Analyses were carried out of the water, chloride, sodium, and potassium concentration of biopsy specimens of human myometrium. Comparisons were made between the values found in various stages of the menstrual cycle, in menopause, in pregnancy, and in other various pathological states.

Metabolism of Progesterone in Human Myometrium

Endocrinology, 1969
In vitro incubation experiments with human myometrium collected during the proliferative phase of the ovarian cycle demonstrate progesterone-4-14C to be metabolized to 5 products, namely, pregn-4-en-20α-ol-3-one, 5α-pregnan-3,20-dione, pregn-4-en,6β-ol-3,20-dione, 5α-pregnan-20α-ol-3-one, and an unidentified product. The rate of progesterone metabolism

Ultrastructure of the Myometrium

1989
The concept that a well-developed appreciation of structure is an essential prerequisite to an understanding of function permeates research into all physical processes but is especially true for the biological sciences. The electron microscopic and x-ray diffraction studies conducted on the myometrium during the past 25 years have provided important ...

Myocytes, Myometrium, and Uterine Contractions

Annals of the New York Academy of Sciences, 2006
Abstract:  The pregnant uterus is unique because of the dramatic functional changes that occur in the peripartum period. To promote the concept that we have a relatively poor understanding of the physiology of parturition, we will posit 10 facts that are so obvious and so clearly accepted as facts that they probably are not even facts at all.

Postpartum Diffuse Calcification of the Myometrium

International Journal of Gynecological Pathology, 1996
An apparently unique case of diffuse calcification of the myometrium occurring in the puerperum in a 24-year-old woman is reported. Vaginal delivery by forceps of a healthy baby was followed by septic shock and massive postpartum hemorrhage, necessitating hysterectomy 4 weeks later.

Contractions of the inner third of the myometrium

American Journal of Obstetrics and Gynecology, 1990
Forty-six consecutive endovaginal ultrasound examinations were screened for the presence of myometrial contractions. The study group contained pregnant women up to 10 weeks' menstrual age, nonpregnant, and postmenopausal women. Rhythmic myometrial contractions of the inner myometrial third not previously reported were seen in 35 studies in pregnant ...

Biochemistry of the Myometrium

1977
In this consideration of the Biochemistry of the myometrium, we shall be concerned mainly with its contractile function. The uterus is an organ specialized, on the one hand, for the reception of the ovum by the endometrium and the continuous nourishment of the developing fetus and, on the other hand, for its expulsion, by means of the strong isometric ...

[Myometrium diseases].

Journal de radiologie, 2002
Leiomyoma and adenomyosis are the most frequent myometrial disorders, followed by cystic and vascular disorders. After an update on the anatomy, physiology and histology of the myometrium, the authors will describe the normal sonographic and MRI aspects of the uterus.
