Iron incorporation (59Fe) into erythropoietic cells from adult and foetal (11- to 15-day) peripheral blood and from foetal (12- to 15-day) livers has been investigated. Ion-exchange chromatography of haemolysates from such cells revealed two groups of 59Fe-containing proteins. The first group (X-fraction) was eluted from CMC-columns in the void volume and was highest in lysates of immature eryt...

BACKGROUND & OBJECTIVES Doppler velocimetry studies of placental and foetal circulation can provide important information regarding foetal well-being providing an opportunity to improve foetal outcome. The present study was undertaken to evaluate the role of middle cerebral to umbilical artery blood velocity waveform's systolic/diastolic ratio (MCA/UA) and biophysical profile as a predictor of ...

Pathology is the field in medicine dealing with structural and functional changes in tissues and organs which cause or are caused by disease (Taylor, 1988). Foetal pathology is encountered in the foetus aborted either deliberately or spontaneously during the first trimesters of pregnancy (Keeling, 1994). Foetal pathology differs from general pathology in many ways; by focussing on the developme...

1. Although disrupted parturition and high foetal losses have previously been reported in pregnant rats maintained on zinc-deficient diets this is the first report to differentiate between the effects of reduced Zn intake and the effects of reduced food intake on the outcome of pregnancy in the rat. 2. Rats maintained on a 0.5 mg Zn/kg diet for the last 7 d of gestation or on a 5 mg Zn/kg diet ...

Multiplication of Toxoplasma gondii was examined in vitro in murine erythroid cells at different stages of development. Toxoplasma gondii multiplied in nucleated erythroblasts and enucleated reticulocytes from the foetal liver, and in immature reticulocytes and yolk-sac derived erythrocytes from the foetal circulation. However, the rate of multiplication was lowered as erythroblasts matured, an...

Chorioangioma, the non trophoblastic tumour, constitutes the commonest benign growth of the placenta. Though benign, 30% rate of maternal or foetal complications are associated with large masses. Sonography including colour Doppler imaging provides the best modality not only for its diagnosis but also the foetal status. A case of large placental chorioangioma has been reported here resulting in...
