The high oxygen affinity of foetal versus adult blood is an almost universal characteristic of viviparous vertebrates; a notable exception is the cat (Novy & Parer, 1969). There is also likely to be a difference in the oxygen affinities of foetal and adult blood in the teleostean fish, the seaperch Embiotoca lateralis Agassiz. Our studies of E. lateralis foetal and adult haemoglobins and erythr...

activities of the key enzymes of gluconeogenesis in the liver and kidney of the foetal guinea pig have been followed. The foetal guinea pigs used had a gestational age of 68-72 days. Pyruvate carboxylase was present at very low activities in the kidney of the foetus and neonatal animal and also in the foetal liver until day 50, when it increased in activity to reach a value by day 60 of more th...

The association between some risk factors and the presentation of post-partum uterine infections in dairy cattle has been established. However, this association is not comprehensive and the role of other factors has not been widely studied. Here the importance of age, parity, calving season, dystocia and retained foetal membranes (RFMs) was established as some of the potential risk factors for ...

Objective: To assess the perinatal outcome in patients with cord presentation and cord prolapse over a period of 2 years and to assess the obstetric risk factors associated with these cord complications. Design: Retrospective case study. Setting: A tertiary health care centre of India. Sample: All cases of cord presentation and cord prolapse diagnosed in the department over a period of 2 years ...

AIM The study objective was to evaluate the pathological changes of the placenta in foetal death and foetal growth restriction and to find correlation of the findings with clinical causes. SETTING AND DESIGN Prospective study at a tertiary care hospital. MATERIAL AND METHODS Gross and histopathological examinations of the placentae were carried out in pregnancies with foetal demise (IUD) an...

We have previously reported that foetal and adult fibroblasts display distinctive migratory phenotypes when cultured on three-dimensional collagen gels. Both skin and tumour-derived fibroblasts from a significant proportion of patients with breast cancer were subsequently observed to display foetal-like migratory behaviour. In the accompanying paper concerned with the biochemical basis of these...

The acid-base balance in 307 Chinese patients in labour was studied in Tsan Yuk Hospital, Hong Kong over a 15-month period. Fifty-six of these were normal cases, 200 cases exhibited clinical signs of foetal distress and the other fifty-one were high risk cases. The results showed that cases of clinical foetal distress had a significantly lower foetal pH than that in the normal control group. Of...

Foetal well-being during labour is of utmost importance. One of the ways to attempt to assess foetal wellbeing is by recording foetal heart rate (FHR). Loss of variability and deceleration patterns are known to be associated with foetal distress. Decelerations and foetal bradycardia have been described after any type of effective labour analgesia. This review addresses the questions if certain ...
