108 patient were operated on the Neurosurgical Department of the Military Clinical Hospital in Wroc?aw since 1989 till 1991. The stability of the lumbar spine after hemilaminectomy and laminectomy with disc excision and interbody fusion was analysed. The period after operation ranged from 6 months to 2 years. Signs of clinical and radiological instability were the base of the study. Respective segmental motions in maximal ante- and retroflexion were calculated. Horizontal intercorporal dislocation was assessed. No signs of instability where found in the analysed material. The results after laminectomy and hemilaminectomy were similar. The failures were not caused by instability. 相似文献

A third generation gonadotrophin-releasing hormone antagonist (Cetrorelix) was used during ovarian stimulation in 32 patients undergoing assisted reproduction, in order to prevent the premature luteinizing hormone (LH) surge. In all patients, ovarian stimulation was carried out with two or three ampoules of human menopausal gonadotrophin (HMG), starting on day 2 of the menstrual cycle. In addition, 0.5 mg of Cetrorelix was administered daily from day 6 of HMG treatment until the day of ovulation induction by human chorionic gonadotrophin (HCG). A significant drop in plasma LH concentration was observed within a few hours of the first administration of Cetrorelix (P < 0.005). Moreover, no LH surge was detected at any point in the treatment period in any of the 32 patients. A mean oestradiol concentration of 2111 +/- 935 ng/l was observed on the day of the HCG administration, indicating normal folliculogenesis. Like LH, progesterone concentration also dropped within a few hours of the first administration of Cetrorelix (P < 0.005). A 0.5 mg daily dose of Cetrorelix prevented a premature LH surge in all the 32 patients treated. 相似文献
