生殖道沙眼衣原体感染与不孕和自然流产的关系

采用荧光染色技术对１１０例不孕症和３２例自然流产病例的宫颈刮片标本进行检测，其中有３５例（３１．８％）不孕症和１４例（４３．７％）自然而产病人的宫颈上皮细胞内检出沙眼衣原体包涵体。与此同时，对这些阳性病例的配偶进行尿道粘膜印片检查，分别检出尿道粘膜上皮细胞内沙眼衣原体包涵体２９例（８２．６％）和１１例（７８．８％）。对照组系１３６例正常妊娠的孕妇和２００例妇女病普查的病例，分别检出衣原体包涵体５．８％和９．０５％。研究结果表明不孕和自然流产与生殖道沙眼衣原体感染有关。

Fos Expression in the Rat Brain Following Vaginal-Cervical Stimulation by Mating and Manual Probing

Vaginal-cervical stimulation (VCS), provided by mating or manual probing, induces many reproductive behavioral and endocrine changes in female rats. These changes include an increase in lordosis duration, heat termination and pseudopregnancy. Electro-physiological and [¹⁴C]2-deoxy-D-glucose studies collectively show that neurons in the medial preoptic area, ventromedial hypothalamus and midbrain central gray respond to manual VCS. In the present study we immunocytochemically labeled brain sections for Fos, the protein product of the immediate early gene c-fos, to detect VCS-responsive neurons in hormone-primed animals receiving VCS by mating or manual probing. In Experiment 1, females receiving mounts and intromissions were compared to: 1) vaginally-masked females receiving mounts but no VCS, 2) females exposed to an intact anesthetized male or 3) females not exposed to males or the testing arena. Those animals receiving VCS showed a dramatic increase in the number of Fos-immunoreactive cells in the medial preoptic area, posterodorsal portion of the medial amygdala and bed nucleus of the stria terminalis, as well as the dorsomedial hypothalamus, ventromedial hypothalamus and midbrain central gray. These effects of VCS were confirmed in Experiment 2 in animals receiving manual vaginal-cervical probing. These findings extend previous electrophysiological and [¹⁴C]2-deoxy-D-glucose studies by providing evidence that additional brain areas respond to VCS by mating, as well as manual probing.     

Acute Immobilization Stress and Intraventricular Injection of CRF Suppress Naloxone-Induced LH Release in Ovariectomized Estrogen-Primed Rats

The present study was undertaken to evaluate the role and possible interaction of the endogenous opioid peptide (EOP) and corticotropin-releasing factor (CRF) in the acute stress-induced suppression of gonadotropin secretion in ovariectomized estrogen-primed rats. An intravenous (i.v.) injection of naloxone (10 or 20  mg/kg), an EOP antagonist, significantly elevated serum luteinizing hormone (LH) levels within 10  min in non-stressed animals. The naloxone-induced LH release was completely eliminated when tested 30  min after the onset of acute immobilization. In a subsequent study, it was found that suppression of the naloxone-induced LH release occurred as early as 5  min after the stress onset, and was still evident 60  min after the end of a 30-min period of immobilization. The effect of naloxone was restored 3  h after liberation of the animal from the 30-min immobilization. An intraventricular (i.c.v.) injection of CRF (1 or 5  μg) also significantly suppressed, in a dose-related manner, the effect of a subsequent i.v. injection of naloxone. However, an i.c.v. injection of α -helical CRF(9-41) (25 or 50  μg), a CRF antagonist, prior to immobilization, could not interfere with the suppressive effect of stress on naloxone-induced LH release. These results suggest that both acute immobilization stress and CRF can inhibit the LH secretory activity without mediation by EOP neurons. However, the stress-related suppression may involve non-CRF mechanism(s).     

两种剂量的7-甲异炔诺酮对60例绝经后妇女症状控制的比较

目的:探讨两种剂量的7-甲异炔诺酮(OrgOD14,利维爱)对绝经症状控制的比较。方法:60例绝经后妇女随机分为两组:①A组30例,每日口服7-甲异炔诺酮2.5mg。②B组30例,隔日口服7-甲异炔诺酮2.5mg,共6个月。观察服药前后的Kupperman评分变化及血雌二醇、促卵泡激素水平的改变。结果:两组服药后绝经症状明显改善,Kupperman评分明显降低(P<0.01),雌二醇水平显著上升(P<0.01),促卵泡激素水平明显下降(P<0.05),而两组之间差异无显著性。结论:7-甲异炔诺酮可有效地控制绝经症状,每日口服2.5mg并不比隔日口服2.5mg有较好的控制效果(除控制失眠外),故推荐隔日口服2.5mg7-甲异炔诺酮。
