Using a progesterone receptor antagonist, onapristone/ZK 98.299, we examined the in-vivo effects of progesterone on the function of uterine cervix during pregnancy. Onapristone was intravenously administered to pregnant rabbits on day 20 post coitum. After 24 h, the antiprogesterone increased the wet weight of the uterine cervix and decreased the DNA concentration in the cervix. In-situ hybridi...

Abnormal looking cervix, or suspicious cervix, is a common clinical condition seen in gynecological practice. Colposcopic examination of the cervix allows differentiation between physiologic changes that occur in response to normal cyclic variations in hormone secretion and a variety of structural and pathological conditions. This article addresses some of these common clinical problems and pro...

Introduction: Sarcoma of the cervix is uncommon and its prevalence is about 1% of malignancies of the cervix. One type of sarcoma is leiomyosarcoma and the location of this tumor in cervix is very rare. Although uterine sarcoma can involve the cervix and lead to misdiagnosis of cervical leiomyosarcoma, the location of the bulk of the tumor in uterine cervix (not isthmus) for diagnosis of cervic...

Background: Cancer cervix is the most common cancer in women of the developing countries where screening facilities are inadequate. Cancer cervix is a preventable cancer due to its long pre invasive stage and availability of screening methods. Colposcopy is an in situ clinical examination of cervix with magnification and illumination. It is a clinical method that complements the laboratory meth...

Standard radiation therapy for patients undergoing primary chemosensitized radiation for carcinomas of the cervix usually consists of external beam radiation followed by an intracavitary brachytherapy boost. On occasion, the brachytherapy boost cannot be performed due to unfavorable anatomy or because of coexisting medical conditions. We examined the safety and efficacy of using CyberKnife ster...

A decline in serum progesterone or antagonism of progesterone receptor function results in preterm labor and birth. Whether characteristics of premature remodeling of the cervix after antiprogestins or ovariectomy are similar to that at term was the focus of the present study. Groups of pregnant rats were treated with vehicle, a progesterone receptor antagonist (onapristone or mifepristone), or...

Small cell carcinoma of the uterine cervix is rare. It is estimated that 10% of patients with small-cell lung cancer have syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and hyponatremia has been reported to be significantly associated with a poor prognosis. A proportion of small cell carcinoma of the uterine cervix exhibit neuroendocrine characteristics as revealed by immun...

Bilateral neurectomy of the pelvic nerve (BLPN) that carries uterine cervix-related sensory nerves induces dystocia, and administration of its vasoactive neuropeptides induces changes in the cervical microvasculature, resembling those that occur in the ripening cervix. This study was designed to test the hypothesis that (a) the cervix of pregnant rats expresses vascular endothelial growth facto...

As the critical gatekeeper for birth, prepartum remodeling of the cervix is associated with increased resident macrophages (Mφ), proinflammatory processes, and extracellular matrix degradation. This study tested the hypothesis that expression of genes unique to Mφs characterizes the prepartum from unremodeled nonpregnant cervix. Perfused cervix from prepartum day 21 postbreeding (D21) or nonpre...
