Umbilical Cord Segmental Hemorrhage and Fetal Distress
Umbilical Cord Segmental Hemorrhage Fetal Distress
2009/4/20
We describe an unexplained case of umbilical cord segmental hemorrhage linked with meconium-stained amniotic fluid. A severely asphyxiated infant was delivered at term by Caesarean section. There we...

Development of transmembrane signaling in the fetal rat Leydig cell
transmembrane signaling fetal rat Leydig cell
2009/2/23
Gonadotropin binding to the adult Leydig cell activates a GTP binding protein that interacts with adenylate cyclase to increase cAMP production within the cell. The increased production of cAMP stim...
Fetal irradiation increases androgen production by dispersed leydig cells of the rat
seminiferous tubule damage fetal irradiation
2009/2/20
Damage to the seminiferous epithelium of the rat has been shown to decrease the concentration of serum testosterone. In these animals, compared to controls, the structure of the Leydig cells sugge...
Squash preparation studies of germ cells in human fetal testes
testis preleptotene germ cells chromosomes
2009/2/20
Testes from human fetuses 21 to 41 weeks of gestation were investigated using a modified squash technique. At all of the gestational ages examined, 90 to 95% of the germ cells were in interphase. Pr...
Morphometric and immunocytochemical study of the fetal, infant, and adult human vas deferens
Epithelium testicular developmental phases
2009/2/17
The human vas deferens (VD) is often considered simply as a conduit to transfer mature sperm from the epididymis to the ejaculatory duct. The cells that make up the epithelium of the VD, however, ex...
Cloning and partial sequence of the rabbit androgen receptor：expression in fetal urogenital tissues
Development mesonephros androgen receptor urogenital sinus rabbit prostate
2009/2/13
Genetic studies indicate that the actions of testosterone and dihydrotestosterone are mediated by a single androgen receptor (AR). The basis for the differential effects of these hormones during d...
Androgen-induced prevention of the outgrowth of cranial gonadal suspensory ligaments in fetal rats
rat testis descent maldescent cryptorchidism
2009/2/11
Normal and disturbed testicular descent is frequently approached exclusively through a consideration of the caudal testicular suspensory apparatus. This is surprising, because embryonal gonads dev...

Background: According to the fetal overnutrition hypothesis, intrauterine influences of maternal obesity increased lifelong obesity risk in the offspring. If the hypothesis is true, then the associati...
利用孕妇血浆DNA检测胎儿性别的研究Application of Fetal DNA in Maternal Plasma for Non-invasive Prenatal Diagnosis of Fetal Sex
巢式PCR 血浆DNA 性别鉴定 产前诊断
2008/1/10
摘要本文探讨应用孕妇血浆中游离DNA进行无创性产前性别诊断的可行性。用柱分离法提取73例孕妇血浆中DNA，用巢式PCR技术检测其胎儿SRY基因。 结果73位孕妇血浆DNA含量为0.0062~0.3399μg/μL。巢式PCR检测胎儿SRY基因的灵敏度为97.37%（37/38），假阴性率2.86%(1/35)，特异度85.71%（30/35），假阳性率13.16%(5/38)，总符合率91.78%...

有核红细胞 免疫组化 Duchenne型肌营养不良症 (DMD)
2008/1/6
摘要以孕8~26周孕妇外周血为材料，经过Percoll密度梯度离心初步富集，胎儿细胞特异性抗体—HbF标记、识别胎儿有核红细胞，母体和胎儿有核红细胞的精确区分是以胎儿和成人血红蛋白的组成差异为基础的。胎儿细胞胞浆黄染，而具有成人血红蛋白的母体细胞没有颜色。显微操作法获取全部阳性细胞后，以其全基因组扩增（PEP）的产物为模板，进行性别检测、DMD基因的多重PCR检测和STR连锁分析。结果，20名孕妇...
