Radiation dose reduction during hysterosalpingography: an application of scanning-beam digital radiography

Hysterosalpingography was performed in 31 patients by means of a low-dose scanning-beam digital radiographic system. The technique permits adequate evaluation of gynecologic abnormalities while allowing significant reduction in radiation: 2.4-mR (6.1 X 10(-7) C/kg) exposure to the skin and 0.7-mrad (7 X 10(-6) Gy) mean dose to the ovaries per image obtained. Sixteen patients demonstrated readily recognizable and documented abnormalities, corroborated by laparoscopy, laparotomy, or other supportive evidence.     

3种培养基体外培养人芽囊原虫的效果观察

目的　观察人芽囊原虫在 3种培养基中的生长繁殖情况 ,以探讨最佳的培养方法。　方法　从大学生粪便中分离人芽囊原虫 ,转种至 3种不同培养基 ,定时观察人芽囊原虫的生长繁殖情况 ,根据原虫密度评价培养效果。　结果培养 96h后 ,Locke’s鸡蛋血清 (LES)双相培养基中的人芽囊原虫密度最高 ,改良Jones单相液体培养基次之 ,Locke’s琼脂血清 (LAS)双相培养基原虫密度最低 ,差异有显著性 (P <0 .0 5 ) ;观察 3种培养基中的原虫密度高峰持续时间分别为 3 60h、96h和 72h ,最长存活时间分别为 5 5 2h、3 3 6h和 168h。　结论　Locke’s鸡蛋血清双相培养基较适用于人芽囊原虫体外增殖培养。

彩色多普勒超声在精索扭转诊断和鉴别诊断中的价值

目的 :应用彩色多普勒超声鉴别精索扭转和急性睾丸炎。　方法 :回顾性分析 13例急性睾丸疼痛病人的彩色多普勒血流显像 (CDFI)表现和治疗情况。　结果 :8例显示睾丸内血流信号稀疏或消失 ,诊断为精索扭转 ,其中 1例手法复位成功 ,7例手术探查并得以证实。其余 5例显示患侧睾丸血流信号丰富 ,诊断为急性睾丸炎或睾丸附睾炎 ,经抗生素治疗后症状好转 ,超声复查显示血流减少。　结论 :CDFI在精索扭转诊断和鉴别诊断中具有重要意义 ,可作为急性睾丸疼痛病人的首选检查方法
