本文研究了不同外源激素组合对诱导同一花被不同部位细胞分化花芽的影响.测定了花被上部、中部、下部切块离休培养前后的内部IAA和Z+ZR会量。结果表明,风信子同一花被不同部位细胞均能分化花芽。当MS培养基中附加2.0mg... 本文研究了不同外源激素组合对诱导同一花被不同部位细胞分化花芽的影响.测定了花被上部、中部、下部切块离休培养前后的内部IAA和Z+ZR会量。结果表明,风信子同一花被不同部位细胞均能分化花芽。当MS培养基中附加2.0mg/L的zeatin或6-BAP时,随着外源IAA浓度从0升高到10.0mg/L,花芽分化部位由花被下部向上部移动。 展开更多

Objective: To evaluate the outcomes of selective uterine artery embolization (SUAE) in treatment of symptomatic uterine fibroids using Color Doppler ultrasonography (CDUS). Methods: As the procedure SUAE for fibroids, prospective data of the initial 65 consecutive women treated from March 2007 to September 2009 were collected. The follow-up period from 1 week to 30 months, using questionnaires, we investigated the fibroid-related physical and psychological symptoms, and the cumulative rates of symptom control, gynecologic interventions, and complications. The volumes of uterine and uterine fibroids were calculated by CDUS pre- and post-SUAE for 6 months. And we tested the levels of internal hormone including FSH, LH and E2 before and after SUAE for 3, 6 months. Results: SUAE was performed successfully in all patients. There was no peri-operative morbidity in all procedures. Compared with pre-SUAE volumes of uterine [(322± 12) cm^3] and uterine fibroids [(125±46) cm^3], their volumes in post-SUAE were (144±72) cm^3 and (51 a:l 1) cm^3 (P〈0.01), and reduction rate was 58% and 61%, respectively. At 3, 6 months after SUAE, levels of FSH, LH, and E2 were not decreased than that of in pre-SUAE (P〉0.05). After SUAE for 24 months, the fibroids related physical and psychological symptoms such as bleeding, pain and quality of life were significantly improved (P〈0.01). 90.8% (59/65) women had resolution of symptoms and no significant post-procedural symptoms. Parts of patients discharge necrotic fibroids. 86% (34/40) complications were minor, requiring no therapy. 9.2% (6/65) had significant post-procedural symptoms, requiring therapy in hospital or out-patient department. Conclusion: SUAE contributes to a long-term significant improvement of all investigated uterine fibroid-related symptoms and markedly improves women's health-related quality of life. SUAE that no impair on changes of internal hormone, under suitable conditions, represents an attractive alternative to hysterectomy for the treatment of symptomatic fibroids and is a minimally invasive, new method of good clinical prognosis. CDUS is an effective to investigate the outcome of SUAE. 展开更多
