目的探讨复方保元煎对老龄雌性小鼠阴道、子宫及生殖激素变化的影响。方法选择15个月龄老龄雌性小鼠90只,体重(49±1.3)g,将其随机分为复方保元煎高剂量组30只,复方保元煎低剂量组30只,空白对照组30只,各组给药3个月,麻醉后颈动脉取血分离血清,测血清促黄体生成素(LH)、孕酮(P)、雌二醇(E2)、血促卵泡激素(FSH),处死后剥离阴道及子宫称重,HE染色观察子宫组织形态学变化。结果复方保元煎高剂量组和低剂量组用药后老龄雌性小鼠阴道和子宫重量显著提高,均明显优于空白对照组(P<0.01),复方保元煎高剂量组和低剂量组之间无显著性差异(P>0.05)。复方保元煎高剂量组和低剂量组均能明显延缓甚至逆转小鼠子宫萎缩状况。复方保元煎高剂量组和低剂量组用药后老龄雌性小鼠血清E2、LH、P、FSH含量比较均有显著性差异(P<0.01),用药后与空白对照组比较均有显著性差异(P<0.01),复方保元煎高剂量组与低剂量组用药前后比较无显著性差异(P>0.05)。结论复方保元煎能有效调节衰老小鼠的激素水平,延缓和逆转小鼠生殖系统退化,为开发治疗绝经后冠心病天然雌激素新药提供了可借鉴的实验依据。 相似文献

AIM: To investigate if vitamin D receptor (VDR) gene Apa I polymorphism and estrogen receptor-α (ER-α) gene Pvu II, Xba I polymorphisms are related to bone mineral density (BMD), bone mineral content (BMC) and bone size in premenopausal Chinese women. METHODS: The VDR Apa I genotype and ER-α Pvu II, Xba I genotype were determined by PCR-restriction fragment length polymorphism (RFLP) in 493 unrelated healthy women aged 20-40 years of Han nationality in Shanghai city.… 相似文献

As a topic of psychoanalytic inquiry, menstruation is surprisingly absent from psychoanalytic literature: menstruation as a part of female psychosexual development is in need of further empirical exploration. The research uses semi‐structured interviews with six young women to explore individual experiences of the menarche and menstruation. The data is analysed using narrative and thematic analysis and interpretations, made within a (broadly classical) psychoanalytic frame, drive the results. In this condensed version of the research, three central findings will be discussed: (1) the role of mother in negotiating the menarche; (2) the difficulty of irregular periods and the fear that something internal has ‘gone wrong’; (3) the link to ideas of mess, dirt and shame, potentially reflective of feelings about sexuality. The research concludes that menstruation is an area worthy of careful psychoanalytic consideration in theory and in clinical practice. 相似文献

With the rapid development of China''s space industry, the importance of radiation protection is increasingly prominent. To provide relevant dose data, we first developed the Visible Chinese Human adult Female (VCH-F) phantom, and performed further modifications to generate the VCH-F Astronaut (VCH-FA) phantom, incorporating statistical body characteristics data from the first batch of Chinese female astronauts as well as reference organ mass data from the International Commission on Radiological Protection (ICRP; both within 1% relative error). Based on cryosection images, the original phantom was constructed via Non-Uniform Rational B-Spline (NURBS) boundary surfaces to strengthen the deformability for fitting the body parameters of Chinese female astronauts. The VCH-FA phantom was voxelized at a resolution of 2 × 2 × 4 mm3for radioactive particle transport simulations from isotropic protons with energies of 5000–10 000 MeV in Monte Carlo N-Particle eXtended (MCNPX) code. To investigate discrepancies caused by anatomical variations and other factors, the obtained doses were compared with corresponding values from other phantoms and sex-averaged doses. Dose differences were observed among phantom calculation results, especially for effective dose with low-energy protons. Local skin thickness shifts the breast dose curve toward high energy, but has little impact on inner organs. Under a shielding layer, organ dose reduction is greater for skin than for other organs. The calculated skin dose per day closely approximates measurement data obtained in low-Earth orbit (LEO). 相似文献

BackgroundPrenatal alcohol exposure is a leading cause of neurobehavioral and neurocognitive deficits collectively known as fetal alcohol spectrum disorders, including eating disorders and increased risk for substance abuse as very common issues. In this context, the present study aimed to assess the interaction between prenatal and lactation alcohol exposure (PLAE) and a high-fat diet (HFD) during childhood and adolescence.MethodsPregnant C57BL/6 mice underwent a procedure for alcohol binge drinking during gestation and lactation periods. Subsequently, PLAE female offspring were fed with an HFD for 8 weeks, and thereafter, nutrition-related parameters as well as their response to cocaine were assessed.ResultsIn our model, feeding young females with an HFD increased their triglyceride blood levels but did not induce overweight compared with those fed with a standard diet. Moreover, PLAE affected how females responded to the fatty diet as they consumed less food than water-exposed offspring, consistent with a lower gain of body weight. HFD increased the psychostimulant effects of cocaine. Surprisingly, PLAE reduced the locomotor responses to cocaine without modifying cocaine-induced reward. Moreover, PLAE prevented the striatal overexpression of cannabinoid 1 receptors induced by an HFD and induced an alteration of myelin damage biomarker in the prefrontal cortex, an effect that was mitigated by an HFD-based feeding.ConclusionTherefore, in female offspring, some effects triggered by one of these factors, PLAE or an HFD, were blunted by the other, suggesting a close interaction between the involved mechanisms. 相似文献

With the increasing prevalence of obesity worldwide, obesity-related female stress urinary incontinence (FSUI) has become a key health problem. Recent studies indicated that FSUI is primarily caused by obesity-related pathological changes, such as fat droplet deposition, and results in pelvic floor nerve, vascular, and urethral striated muscle injury. Meanwhile, treatments for obesity-associated FSUI (OA-FSUI) have garnered much attention. Although existing OA-FSUI management strategies, including weight loss, pelvic floor muscle exercise, and urethral sling operation, could play a role in symptomatic relief; they cannot reverse the pathological changes in OA-FSUI. The continued exploration of safe and reliable treatments has led to regenerative therapy becoming a particularly promising area of researches. Specifically, micro-energy, such as low-intensity pulsed ultrasound (LIPUS), low-intensity extracorporeal shock wave therapy (Li-ESWT), and pulsed electromagnetic field (PEMF), have been shown to restore the underlying pathological changes of OA-FSUI, which might be related by regulation endogenous stem cells (ESCs) to restore urine control function ultimately in animal experiments. Therefore, ESCs may be a target for repairing pathological changes of OA-FSUI. The aim of this review was to summarize the OA-FSUI-related pathogenesis, current treatments, and to discuss potential therapeutic options. In particular, this review is focused on the effects and related mechanisms of micro-energy therapy for OA-FSUI to provide a reference for future basically and clinical researches. 相似文献
