This study defines normal growth for the various aortic segments in 128 spontaneously aborted human foetuses aged 15-34 weeks. With the use of anatomical dissection, digital-image analysis (using the Leica Q Win Pro 16 system) and statistical analysis (ANOVA, regression equation), a range of length measurements for the ascending aorta, aortic arch and thoracic aorta was examined. No significant...

Border disease is a congenital viral disease of sheep and goats and cause significant economic losses worldwide. It may cause abortion in sheep. However, there isn’t any report of ovine abortion due to this virus from Iran. The aim of the present study was to investigate the role of this viral infection in sheep abortions in Chaharmahal and Bakhtiari province. To this end, 100 samples of aborte...

Maturation of neurons of the myenteric plexus (MP) of human fetal sigmoid colon was studied at various weeks of gestation (WG). There is abundant literature on the development of MP in various segments of the gut but there are fewer reports on the development of MP in human sigmoid colon which is a site of various disorders. Sigmoid colonic segments from 12 aborted foetuses aged 14-23WG were pr...

Birth defects are structural abnormalities which develop in foetuses during their intrauterine life. Depending on the underlying cause, birth defects may affect one or more organ systems and sometimes present as recognizable syndromes. According to large series studies, defects of the heart (affecting about 1 in every 100 to 200 livebirths), neural tube (affecting 1 of every 1000 pregnancies), ...

Incorporation and release of the radioactivity in the liver glycogen of 18.5- and 19.5-day-old rat foetuses were studied after intravenous injection of E11-14C]glycerol. Incorporation occurred during 1 h after injection of the radioactive tracer to the foetus; then, the incorporated radioactivity decreased. Glycogen content in the liver, and glycogen phosphorylase and glycogen synthase were not...

1. The absorption of zinc by the duodenum of the rat was greatly enhanced at late stages of pregnancy and during lactation. 2. During pregnancy no increase in lysine uptake could be demonstrated, but during lactation, when further increases in Zn absorption occurred, uptake of lysine was increased. 3. The increased absorption of Zn at different stages of pregnancy and lactation appeared to be r...
