Intimal ultrastructure of human umbilical arteries. Observations on arteries from newborn children of smoking and nonsmoking mothers.
The umbilical artery was chosen as a possible model for evaluating the vascular injury provoked by tobacco smoking in humans. Cords from newborn children delivered by 15 nonsmoking and 13 smoking mothers were studied in the transmission and the scanning electron microscope. Pronounced intimal changes were seen in the arteries from smoking mothers; the most important findings were degenerative c...
متن کاملUltrastructure of human umbilical arteries. Studies on arteries from newborn children delivered by nonsmoking, white group D, diabetic mothers.
The effect of diabetic metabolism on the human vascular wall studied, using the fetal cardiovascular system at birth as an experimental model. The ultrastructure of umbilical arteries from nine newborn children of nonsmoking diabetic mothers (White group D) was compared with that of 30 healthy nonsmokers. Intimal cushions, thickening of the basement membrane often with a multilaminal appearance...
متن کاملConstriction of Human Umbilical Arteries
Experiments on perfused segments or isolated rings of human umbilical artery showed that the magnitude of their contraction in response to bradykinin, epinephrine, or serotonin depended on the P02 of the perfusing or bathing solution. Constriction to bradykinin varied directly with the O2 tension and was greatest when the Po2 was approximately that of umbilical arterial blood during the transit...
متن کاملProteoglycans of human umbilical cord arteries.
Proteoglycans (PGs) were dissociatively extracted from human umbilical cord arteries (UCAs) with 4 M guanidine hydrochloride containing Triton X-100 and protease inhibitors, purified by Q-Sepharose anion exchange chromatography and lyophilized. They were analysed by gel filtration, SDS/PAGE and agarose gel electrophoresis before and after treatment with chondroitinase ABC. It was found that the...
متن کاملUltrasound observations of subtle movements: a pilot study comparing foetuses of smoking and nonsmoking mothers
AIM One way to assess foetal health of smokers is to ask mothers to count perceived movements, an unreliable method hiding differences in prenatal development. The aim of this pilot study was to assess subtle foetal movements in ultrasound scans and establish whether they differ in foetuses of mothers who smoked and nonsmoking mothers. METHODS This longitudinal pilot study recruited twenty mo...
