متن کاملDifferent changes in resistance index between uterine artery and uterine radial artery during early pregnancy.
BACKGROUND Changes in blood flow impedance of the uterine artery (UA) and uterine radial artery (RA) which is in the lower-extremity of the UA were examined during early pregnancy. METHODS Blood flow impedance was assessed by transvaginal color-pulsed-Doppler-ultrasonography in 72 women from weeks 4-16 of pregnancy and expressed as a resistance index (RI). RESULTS RA-RI remained at the late...
متن کاملUterine artery Doppler velocimetry , calcium and lipids in pregnant women of advanced age
Women of advanced maternal age are considered to be at a substantially increased risk of spontaneous abortion. The increased spontaneous abortion rate in older women rnight be associated with a defective vascular response to placentation, which rnight lead to fetal ischaemia and fetal dead. Doppler velocirnetry of the uterine artery allows non-invasive assessment of uteroplacental hemodynamics....
متن کاملThe Effects of HCG on the Distribution Pattern of Mature Pregnant Rat Uterine Glycoconjugates during Implantation Period
Introduction: One of the most common reasons of infertility is un-ovulatory period. Hormone therapy is the most common treatments of this type of infertility. Gonadotropins may exert toxic effects on the molecular organization of uterine surface, such as glycoconjugates. Glycoconjugates are the most important components of the uterine and trophoblast surface playing an important role in embryo ...
