[show abstract][hide abstract] ABSTRACT: The purpose of this work was to investigate whether clinical cytology could be useful in the preoperative diagnosis of pelvic actinomycosis.
This study involved the prospective collection of samples derived from the endometrium and the uterine cervix, and retrospective data analysis. Nine patients with clinically diagnosed pelvic actinomycosis were enrolled. The clinical and hematological characteristics of patients were recorded, and detection of actinomyces was performed by cytology, pathology, and bacteriological culture of samples and by imprint intrauterine contraceptive device (IUD) cytology.
The detection rate of actinomyces was 77.7% by combined cervical and endometrial cytology, 50.0% by pathology, and 11.1% by bacterial culture.
The higher detection rate of actinomyces by cytology than by pathology or bacteriology suggests that careful cytological examination may be clinically useful in the preoperative diagnosis of pelvic actinomycosis.

[show abstract][hide abstract] ABSTRACT: We investigated the effect of human seminal fluid on the growth of endometrial cells derived from women with and without endometriosis.
Seminal plasma (SP) was collected from 18 healthy fertile men. Serum, peritoneal fluid (PF) and tissue specimens of eutopic and ectopic endometrium were collected from 45 women with endometriosis and 20 women without endometriosis during laparoscopic surgery. Prostaglandin (PG) E2, hepatocyte growth factor (HGF), and estradiol (E2) levels in each sample of SP, serum and PF were measured by enzyme-linked immunosorbent assay. The growth pattern of cells derived from eutopic and ectopic endometria in response to SP was examined by 5-bromo-2-deoxyuridine (BrdU) incorporation assay.
Seminal plasma was able to significantly stimulate the growth of epithelial cells and stromal cells derived from the eutopic and ectopic endometria of women with endometriosis (2-3-fold) when compared with control media. The SP-promoted proliferation of both gland cells and stromal cells derived from eutopic endometria was also remarkably higher in women with endometriosis than that of women without endometriosis. Although levels of PGE2, HGF and E2 in SP were variable when compared with other body fluids, the levels of PGE2 and HGF in SP were significantly higher than those in either peritoneal fluid or serum of women with or without endometriosis. Pretreatment of cells with individual anti-PGE2 antibody, anti-HGF antibody and two selective estrogen receptor modulators, tamoxifen and raloxifene was unable to suppress SP-mediated growth of endometrial cells. However, pretreatment of cells with combined anti-PGE2 antibody plus anti-HGF antibody or combined anti-PGE2 antibody plus anti-HGF antibody plus tamoxifen or raloxifene was able to significantly suppress SP-promoted growth of eutopic and ectopic endometrial cells.
Human seminal fluid enriched with different macromolecules may promote the growth of endometrial cells derived from women with endometriosis. Our findings may suggest some detrimental effect of unprotected sexual intercourse in women with endometriosis.
