The aim of this study was to determine the first trimester human peripheral arterial and venous blood flow between 5 - 10 weeks of gestation. Two hundred twenty four women with singleton, uncomplicated pregnancies were prospectively studied with transvaginal ultrasound. Ductus venosus, umbilical artery waveforms and pulsatility indexes (PI) were assessed as well as the waveform of the umbilical...

1. Animal and human work has indicated that maternal oxytocin secretion is under the control of endogenous opiates. Previous workers have described the fetal production of oxytocin in addition to maternal production. The study of the interaction between exogenously administered opiates and oxytocin secretion may give insight into the activity of any opiate-mediated regulatory mechanism of oxyto...

A major obstacle to coherent terminology for liver anatomy and resections has been that American and French anatomists have divided the left side of the liver through different planes. Couinaud divided the left hemiliver into "sectors" by a plane through the left hepatic vein. Healey and Schroy divided it into "segments" through the umbilical fissure. One anatomic justification for Couinaud's s...

Ritodrine hydrochloride concentrations were measured by radioimmunoassay in maternal and fetal sera and amniotic fluid from eight, pregnant, volunteers. Each patient agreed to have 420 micrograms . kg-1 of ritodrine infused intra-venously over two hours prior to elective cesarian section. During infusion a blood sample was taken every 30 minutes from a maternal peripheral vein. Once anesthesia ...

Fetal intra-abdominal umbilical vein (FIUV) varix is a rare malformation of the umbilical cord. This is a critical situation due to discrepancies in outcomes varying from normal to high rates of complications and fetal mortalities. We report the observation of a FIUVV vein diagnosed precociously at 22 weeks with a quiet increasing of the diameter by 31 weeks. The outcome was favourable and clos...

The effects of human tumour necrosis factor-alpha (TNFalpha), or its mutein (F4168) having the cell adhesive Arg-Gly-Asp sequence at the N-terminus, on intestinal injury, were examined. Histopathological examination revealed that an intravenous injection of TNFalpha resulted in marked haemorrhage or oedema in the caecum of rats, whereas F4168 showed no such effects even at the same therapeutic ...

Recent investigations of the birth changes in the foetal circulation indicate that certain channels, namely, the ductus arteriosus, ductus venosus and extra-abdominal umbilical vessels, are quickly closed by the contraction of their muscular walls (Barclay, Franklin and Prichard, 1944). This immediate functional closure is followed by an anatomical obliteration which takes place during the firs...

AIM This study was conducted with the objective of identifying and evaluating intrapartum fetal stress in connection with the type of delivery in bitches. MATERIALS AND METHODS A total of 26 bitches between 1 and 5 years, belonging to 10 different breeds were evaluated. Bitches were subjected to detailed clinico-gynecological examination based on history. Neonatal stress associated with spont...

OBJECTIVE Anti-endothelial cell antibodies in serum of patients with different inflammatory diseases can be detected by a whole cell enzyme-linked immunosorbant assay, using primary cultures of human umbilical vein endothelial cells. To avoid repeated isolation, it would be of great value if an immortal endothelial cell line could be used to perform anti-endothelial cell antibody assays. METH...
