中药生精冲剂对精索静脉曲张大鼠的治疗

目的：研究中药生精冲剂对大鼠精索静脉曲张的影响及疗效。方法：从80只SD雄性大鼠中随机抽出20只作为假手术组，余60只均建立精索静脉曲张病理模型后随机均分为模型组、生精冲剂组和克罗米芬组。造模后15d生精冲剂组和克罗米酚组分别给予生精冲剂4g/（kg·d）和克罗米芬20mg/（kg·d）灌胃，模型组和假手术组正常喂食。造模后45d放免法测定血清性激素（FSH、LH和T）及观察各组大鼠睾丸组织结构。结果：生精冲剂组大鼠光镜下睾丸组织结构优于模型组和克罗米芬组；血清FSH、LH生精冲剂组显著低于模型组和克罗米芬组（P〈0.05），而克罗米芬组显著高于其他3组。T在生精冲剂组、克罗米芬组和假手术组之间无显著差异，但均显著高于模型组（P〈0.05）。结论：中药生精冲剂对精索静脉曲张引起的睾丸损害有保护及修复作用，且可能优于克罗米芬。

复方丹参滴丸对急慢性高粘滞血症模型血管内皮细胞分泌功能的影响

目的：观察复方丹参滴丸对高粘滞血症血管内皮分泌功能的影响，探索其作用机制。方法：复合因素(高分子右旋糖酐、肾上腺素、牛血清白蛋白)、长时间(112天)造成高粘滞血症慢性模型；一次性静脉注射高分子右旋糖酐。皮下注射(sc)肾上腺素造成急性高粘滞血症模型，分别用复方丹参滴丸进行治疗，观察血管肉皮细胞分泌功能的变化。结果：慢性高粘滞血症模型血浆血栓素B2(TXB2)和内皮素(ET)浓度非常显升高，而6-酮-前列腺素F1x(6-酮)浓度非常显降低；急性高粘滞血症模型血管内皮分泌功能无显变化；长期使用复方丹参滴丸能调整、改善血管内皮分泌功能的异常状态；复方丹参滴丸改善血管内皮分泌功能的即时效应不显。     

Feasibility of administering mifepristone as a once a month contraceptive pill

Many women find the idea of a once-a-month contraceptive pill an attractive concept. Mifepristone has been shown to be effective as a contraceptive if administered in the early luteal phase. We tested the contraceptive efficacy of 200 mg of mifepristone on day luteinizing hormone (LH) + 2 in a group of 32 women who used a fertility monitor to identify the LH surge. We also recruited a control group, comprising 20 women who were trying to conceive. In this group, 12 women conceived during a total of 50 control cycles (probability of pregnancy 0.25-0.32). Women in the treatment group contributed to a total of 178 cycles and there were two pregnancies (probability of pregnancy 0.01). An LH surge was not detected in 34 cycles (19.1%). In 20 cycles (11.2%) this was due to imperfect use while 14 were monitor method failures (7.9%). Treatment with mifepristone in the early luteal phase did not disrupt the cycle length but women reported slight vaginal bleeding in 15% of the cycles. The combination of a home-use fertility monitor with once-a-month administration of mifepristone (especially if mifepristone is administered at the early luteal phase) is an acceptable contraceptive option with minimal side effects. Unfortunately, it is difficult to envisage how an easier way of defining the correct timing, which required less compliance, could be devised.     

五淋丸对大鼠异丙肾上腺素性缺血心肌的保护作用及其机制探讨

目的：观察五淋丸对异丙肾上腺素（Iso）诱发的大鼠心肌缺血的保护作用。方法：采用腹腔注射诱导大鼠致急性心肌缺血的动物模型。实验大鼠随机分为Iso模型组，阳性对照组和五淋丸大、中、小剂量组，观察各组大鼠心电图ST-iunction（J点）的位移、血清酶及血流动力学变化。结果：五淋丸大、中、小剂量组大鼠心电图J点的位移明显低于模型组（P〈O．05或P〈0．01）；血清肌酸激酶（（K）及乳酸脱氢酶（LDH）活性低于模型组（P〈O．01）；血流动力学指标：左心室收缩压（LVSP）、左心室舒张末压（LVEDP）、左心室等容期压力最大变化速率（土dp／dtmax）显著高于模型组（P〈O．05或P〈0．01）。结论：五淋丸对异丙肾上腺素所致大鼠缺血心肌具有保护作用，其机制可能与其改善心肌缺血大鼠心脏的舒缩功能有关。

The public health implications of the 1995 'pill scare'

The warning issued by the UK Committee on Safety Medicines in October 1995, followed by their 'Dear Doctor' letter of October 18, 1995, that oral contraceptive pills containing gestodene or desogestrel were associated with a higher risk of venous thromboembolism has had a negative impact on public heath. A significant number of women either switched brands or ceased contraception altogether following the announcement. National data suggest a strong association between the pill scare and a substantial increase in the number of unintended pregnancies, particularly significant among younger women, with use of oral contraception falling from 40 to 27% of under 16s between 1995-1996 and 1996-1997. The resulting cost of the increase in births and abortions to the National Health Service has been estimated at about Pound Sterling 21 million for maternity care and from Pound Sterling 46 million for abortion provision. The level of risk should, in future, be more carefully assessed and advice more carefully presented in the interests of public health.
