Transfer of embryos into the uterus: How much do technical factors affect pregnancy rates? 总被引:10,自引:0,他引:10

Objective Our objective was to identify the effect on outcome of (a) ultrasound-assisted embryo transfer, (b) the use of different embryo transfer catheters, and (c) the length of time the patients remain in the supine position after embryo transfer.Setting The setting was a private fertility center.Subjects This was a prospective study of 178 in vitro fertilization and embryo transfers (IVF-ET) and 63 frozen embryo replacements (FER).Results The pregnancy rate was 28.7% following IVF-ET and 31.8% for FER. Ultrasound-assisted transfer did not affect the outcome (29 vs 30.3%). There was no difference in the performance of the Wallace and Frydman catheters with regard to outcome (30.3 vs 30.7%). Although there was an increase in pregnancy rate as the time interval in the supine position after ET increased, this needs a larger study.Conclusion The parameter studies did not affect the outcome of IVF/ET or FER. Some factors encouraged us to recommend ultrasound-assisted transfer in some cases, and the use of a Frydman catheter for transfer and to encourage the supine position after transfer for longer periods. 相似文献

尿hCG定量及孕囊直径与药物流产的关系 总被引:12,自引:3,他引:12
本文总结了333例米非司酮配伍米索前列醇抗早孕的资料,分析药流前24h内尿hCG定量及孕囊直径与药流的关系。发现这两项指标与完全流产率和药流出血时间均有关。hCG≤1250U/L或孕囊<10mm者完全流产率最高,分别为100%、96.6%;且出血时间最短,分别为9.6、11.2d。hCG≥20,000U/L或孕囊≥20mm者完全流产率仅约76%。这两项指标之间具良好的相关性。为提高药物流产的质量,建议对尿hCG≥20,000U/L或孕囊直径≥20mm者采取其他终止妊娠方法。 相似文献

Flowers of Spartium junceum L. (Fabaceae) are used for the treatment of gastric ulcers in Turkish folk medicine. Through bioassay-guided fractionation using chemical and chromatographical means and water immersion and restraint-induced stress ulcer model in rats, a saponin fraction was determined as the potent anti-ulcerogenic ingredient. The active fraction was also highly effective in preventing ethanol- and pyloric ligation-induced gastric lesions as well as inhibiting gastric secretion volume, gastric pH and titratable acidity, but did not affect the hexosamine content of the gastric mucosa. A novel oleanen-type triterpenic saponin, named as spartitrioside, was isolated as the active principle by using chromatographical separation techniques. 相似文献

Temporal pattern in the effect of postnatal blood lead level on intellectual development of young children 总被引:7,自引:0,他引:7
Schnaas L Rothenberg SJ Perroni E Martínez S Hernández C Hernández RM 《Neurotoxicology and teratology》2000,22(6):259-810
To determine the temporal pattern of the effect of postnatal blood lead level on the General Cognitive Index (GCI) of the McCarthy Scales of Children's Abilities, we used data from 112 children of the Mexico City Prospective Lead Study with complete evaluations from 36 to 60 months of age at 6-month intervals. We measured blood lead level every 6 months from 6 to 54 months. We controlled for 5-min Apgar, birth weight, birth order, sex, socioeconomic level, maternal IQ, and maximum maternal educational level in a repeated measures ANCOVA using child blood lead level grouped by 6–18 month (geometric mean 10.1 μg/dl, range 3.5–37.0 μg/dl), 24–36 month (geometric mean 9.7 μg/dl, range 3.0–42.7 μg/dl), and 42–54 month (geometric mean 8.4 μg/dl, range 2.5–44.8 μg/dl) averages. There were significant interactions between the 6–18 month blood lead level and age with GCI as the endpoint and between 24–36 month blood lead level and age. The regression coefficient of blood lead at 6–18 months became more negative with age until 48 months, when the rate of decline moderated (linear polynomial contrast p=0.047). The regression coefficient of blood lead at 24–36 months with CGI became more negative as well from 36 to 48 months but then started decreasing toward zero from 48 to 60 months (quadratic polynomial contrast p=0.019). Significant between-subjects lead effects on GCI were found for 24–36 month blood lead level at 48 months (p=0.021) and at 54 months (p=0.073). The greatest effect (at 48 months) was a 5.8-point GCI decrease with each natural log unit increase in blood lead. Significant between-subjects lead effects on GCI were found for 42–54 month blood lead level at 54 months (p=0.040) and at 60 months (p=0.060). The effect of postnatal blood lead level on GCI reaches its maximum approximately 1–3 years later, and then becomes less evident. Four to five years of age appears to be a critical period for the manifestation of the earlier postnatal blood lead level effects. 相似文献
