We developed a new quantitative method for detecting abnormal glycolipid expression in endometrial cells using a monoclonal antibody (MSN-1) and analyzed the glycolipid antigen recognized by MSN-1 in 173 clinical endometrial cell samples (66 normal endometria, 39 endometrial hyperplasias, and 68 endometrial adenocarcinomas). The mean glycolipid antigen levels in normal endometrium, endometrial ...

Introduction: Dysfunctional uterine bleeding (DUB) is defined as increased abnormal endometrial bleeding unrelated to any anatomic lesions/ organic pathology of the genital tract [1]. It is a common problem in woman of reproductive age and about 20% of women affected will seek consultation [2]. Objectives: 1.To study morphological features of endometrium in DUB. 2.To correlate with age, parity ...

BACKGROUND c-Kit is a proto-oncogene that encodes a tyrosine kinase receptor (CD117). Mean platelet volume (MPV) is a useful marker for demonstrating thrombocyte function. We aimed to investigate whether c-kit is expressed in benign, preneoplastic and neoplastic endometrial tissues and whether MPV has a relation with c-kit expression and its intensity. MATERIALS AND METHODS c-Kit expression w...

Previous studies have demonstrated that some human endometrial carcinomas contain an activating point mutation in codon 12 of the Ki-ras protooncogene. To examine the hypothesis that this mutation may occur at an earlier stage of neoplastic progression in the endometrium, we analyzed 89 samples of premalignant endometrial hyperplasia and an additional 84 samples of endometrial carcinoma for poi...

INTRODUCTION Invasive procedures including loop electrosurgical excision, cervical conization, and endometrial sampling are often recommended when atypical glandular cells (AGC) are detected on Pap smear with unsatisfactory colposcopy. These invasive procedures may result in patient anxiety, increased medical expense, and increasing the risk of preterm delivery in subsequent pregnancies. This s...

Vacuum curettage was performed on 348 women who had received various regimens of oestrogen treatment for an average of 9.7 months for climacteric symptoms. In 62 cases (18%) the specimens were unsatisfactory for histological assessment; among the remainder, however, they showed a normal endometrium in 257 cases (90%), cystic hyperplasia in 21 (7%), adenomatous hyperplasia in 7 (2%), and endomet...

BACKGROUND Serum CA-125 has been used as a biomarker of gynecological tumors. In this study, we investigated the CA-125 levels in cervical and vaginal secretions from Chinese patients with endometrial polyps, hyperplasia and carcinoma in comparison with those in endometrium and serum. MATERIAL/METHODS An electro-chemiluminescent immunoassay was utilized to determine the levels of CA-125 in 51...

Deutschsprachige Zusatzinformationen online abrufbar unter: www.thieme-connect.de/ ejournals/toc/gebfra Endometrioid endometrial carcinoma, the most common form of endometrial cancer, usually develops out of a typical sequence of endometrial hyperplasias. The underlying cause of these hyperplasias is a relative predominance of estrogen combined with insufficient progesterone levels. Typical cau...

Modern hormone replacement therapy (HRT) regimens contain oestrogen and progestogen, given either in a cyclical or continuous combined manner. Most endometrial biopsies from women on sequential HRT show weak secretory features. Approximately 15% show proliferative activity, although this figure may be less if more than nine days of progestogen is given in each cycle. A small proportion will sho...
