Background： Removal of the follicular content by ultrasound-guided transvaginal follicle aspiration（TVFA） may fail to induce immediate atresia and loss of function, resulting in the occurrence of residual follicles（RF）. The aims of this study were to characterize the blood flow in RF and to determine the effects of the treatment with estradiol benzoate on RF fate. Lactating, cyclic Holstein-Gir crossbred cows were used. In Experiment 1, follicular wave emergence（D0） was synchronized in cows（n = 10） and follicular growth was then monitored by transrectal ultrasonography from D0 to D8, followed by TVFA of the largest follicle present on the ovaries 24 h later. Color Doppler ultrasound imaging was used to examine blood flow on the follicular wall, which was recorded immediately before and every 12 h after TVFA, up to 72 h. In experiment 2, cows（n = 22） were randomly allocated to receive either 2 mL of saline i.m.（Control group, n = 11） or 2 mL estradiol benzoate i.m.（EB group, n = 11）immediately after TVFA. Ovaries were scanned every 12 h to confirm the presence and to measure the diameter of RF. The contents of the RF, if present, were collected 72 h after the first TVFA, using the same aspiration *** fluid from original follicles and RF were stored at-20 °C until hormonal ***： In Experiment 1, there was no reduction（P 〉 0.05） of blood flow in the remaining follicle walls after TVFA and maximum blood flow values were observed at 49.5 ± 19.7 h post-TVFA. In Experiment 2, formation of RF after TVFA was proportionally similar between Controls（5/9） and EB（5/10） cows. Also, RF diameter did not differ between groups（P 〉 0.05）. Nonetheless, the content of RF from cows in the EB group had lower（P = 0.0004）estradiol（E2） concentration and lower（P = 0.0005） E2：P4 ratio compared with ***： In conclusion, 1） the persistence of vascularization in the remaining follicle wall may contribute to the formation of RF after follicle aspiration,

盆腔脏器下降以及盆底功能紊乱症状

世界核心医学期刊文摘（妇产科学分册） 2005年第11期1卷 3-4页

作者： ghetti C. Gregory W.T. Edwards S.R. 朱国栋 Division of Urogynecology and Reconstructive Pelvic Surgery Department of Obstetrics and Gynecology Oregon Health and Science University Portland OR United States Dr.

Objective: This study evaluates the relationship between symptoms of pelvic floor disorders, and measurement of pelvic organ prolapse. Study design: This retrospective cross-sectional study assessed prolapse in 905 women in an academic urogynecologic practice using the Pelvic Organ Prolapse Quantification exam. Symptoms were assessed with a Likert symptom questionnaire and the Urogenital Distress Inventory. Relationships between symptoms and prolapse were analyzed using Spearman’ s correlation. Results: Symptoms of “ bulging” correlated moderately to the greatest extent of prolapse (r = 0.4, P <.001). Frequency of bother progressively increases when the leading edge descends from -3 and 0. Between ? 1 and ? 5, 90% of women report bother. Symptoms typically attributed to anterior or posterior wall prolapse did not correlate with descent of the respective compartment. Conclusion: “ Bulging” is the principle symptom that correlates with prolapse severity. We found no discrete anatomic position that discriminates between prolapse as a disease state and normal anatomic variation.

Applied Rainwater Harvesting Education： An Australian Case Study

Idris Asset and Services State Water Corporation Parramatta NSW 2150 Australia Faculty of Engineering University of Technology Sydney NSW 2007 Australia Manager Environment Blue Water Joint Venture Prymont NSW 2009 Australia Manager Natural Resource Management Shoalhaven City Council Nowra 2541 Australia Sustainability Strategist Kogarah Municipal Council NSW 2217 Australia

Rainwater tanks have been an integral part of the Australian landscape given the vital role these tanks have played over the years in rural Australia. In the past Local government and Water Authorities actively discouraged the use of rainwater tanks and informing citizens that they were illegal and dangerous. Kogarah Council within the Sydney metropolitan area is a proactive Council, and became the first council in Sydney to adopt Total Water Cycle Management (TWCM) principles into its Sustainability Management Plan, integrating these principles into on-ground projects at a catchment level in a planned and strategic approach. Among it priority projects was the Rainwater Tanks in Schools. This paper outlines how this project assisted all 22 schools in the Kogarah LGA (The Local Government Association) to increase the efficiency of water use and install rainwater tanks to reduce potable water use in toilet flushing and irrigating school gardens. The rainwater harvesting reduced the amount of drinking water used for toilet flushing and/or irrigation. The rainwater tanks also act as a visual reminder to conserve water for the students. The project has equipped the next generation with the necessary tools to make informed decisions and undertake actions that will move towards achieving sustainability.
