Summary. In a selected group of 40 women who had been exposed to diethylstilboestrol in utero , 18 conceived without difficulty and 22 had primary infertility. Among those with primary infertility there was a significantly higher rate of anatomical structural defects and a greater tendency for menstrual disorders than in those without infertility. Thirteen (59%) of the women with primary infertility conceived, most after treatment with ovulation stimulating drugs. Spontaneous abortion and tuba1 pregnancy were frequent (47% and 10% respectively) and similar in both fertility groups. Of 13 infertile women examined, 4 (31%) had mild hyperprolactinemia—a hithero unreported finding for such women. 相似文献

Abstract. Beiner ME, Niv H, Haklai R, Elad-Sfadia G, Kloog Y, Ben-Baruch G. Ras antagonist inhibits growth and chemosensitizes human epithelial ovarian cancer cells. Int J Gynecol Cancer 2006; 16(Suppl. 1): 200–206.
The objective of this article was to determine whether human ovarian carcinoma cells (OVCAR-3) express significant amounts of Ras oncogene and active Ras–guanosine triphosphate (GTP) and, if so, whether the Ras inhibitor farnesyl thiosalicylic acid (FTS) inhibits their growth and chemosensitizes them to cisplatin. We assayed Ras and Ras-GTP in OVCAR-3 cells before and after FTS treatment. The effect of FTS on OVCAR-3 cell growth was assessed in terms of cell number. Because the OVCAR-3 cell line was derived from a patient who was refractory to cisplatin, we examined whether FTS enables cisplatin to induce death of these cells. Significant amounts of Ras and active Ras-GTP were expressed by OVCAR-3 cells and were reduced by 40% by FTS. FTS inhibited OVCAR-3 cell growth in a dose-dependent manner. When combined with cisplatin, FTS reduced the number of OVCAR-3 cells by 80%, demonstrating synergism between FTS and cisplatin. FTS, at a concentration range that allows downregulation of Ras and Ras-GTP in OVCAR-3 cells, also chemosensitizes these cells and inhibits their growth. These results suggest that ovarian carcinomas might respond well to Ras inhibition, both alone and when combined with cisplatin. The combined treatment would allow the use of smaller doses of chemotherapy, resulting in decreased cytotoxicity. 相似文献
