OBJECTIVE To compare uterine artery blood flow in normal first-trimester pregnancies with those complicated by uterine bleeding. METHODS Uterine artery blood flow was investigated by transvaginal color Doppler in 46 pregnant women affected by uterine bleeding and in a control group of 35 women with normal intrauterine pregnancy. Gestational age ranged from the 6th to the 12th week. Three bloo...

condition?inflammatory or otherwise?interfering with the passage of the ovum along the tube and into the uterus ; and (2) some anomaly in the fertilised ovum, such as early disappearance of the corona radiata, favouring its immediate embedding in the uterine tube. The commonest site in which the ovum may become implanted is the ampulla, the widest part of the tube ; and this is accompanied by a...

of lectures on the above subject. The importance of the subject warrants the following abstract : Causation?

The present study was conducted to investigate whether or not protein synthesis in tissues and in the whole body of laying hens would be affected by the position of an ovum passing along the oviduct during egg formation. Protein synthesis in tissues was measured in vivo by a primed-continuous infusion of [15N]methionine for 3 h, finishing at the time when an ovum would have stayed at one of the...
