Noscapine antagonizes vasoconstrictor action of bradykinin in isolated human umbilical artery
Abstract Background: It has been demonstrated that noscapine, an antitussive opioid alkaloid, could antagonize bradykinin- induced responses such as bradykinin effects in guinea-pig ileum, cough induced by bradykinin receptor agonist and angiotensin converting enzyme inhibitors, and brain damage after brain edema both in neonatal rat model and in patients with stroke. In the present study, the...
متن کاملIsolated single umbilical artery and fetal karyotype.
OBJECTIVE To determine the need for fetal karyotyping in cases of an isolated single umbilical artery (SUA) identified during the second-trimester routine anomaly scan. METHODS All patients booked for antenatal care and delivery in our hospital are offered two ultrasound scans in pregnancy, one at 11-13 weeks' gestation as part of screening for chromosomal defects and another at 20-23 weeks f...

متن کاملIsolated single umbilical artery--the case for routine renal screening.
To determine the incidence of silent renal anomalies in infants with isolated single umbilical artery (SUA), all infants with SUA and without other obvious congenital anomalies, identified over a six year period, were screened using renal ultrasonography. Over 35,000 placentas were examined. An isolated single umbilical artery was identified in 112 (0.32%). Nineteen infants had abnormal renal i...
متن کاملCharacterization of receptors involved in serotonin contractions of isolated human umbilical artery in uncomplicated pregnancy
Background Serotonin (5-HT), is a vasoactive substance involved in physiological functioning of fetoplacental blood flow and continuous modulation of smooth muscle tone in umbilical vein and arteries. Since umbilical blood vessels have been shown to be deficient in autonomic innervation, the action of local autocrine vasoactive substances (including serotonin) is of considerable importance. Alt...
