ABSTRACT
118 patients with chronic liver diseases were subjected to scintigraphic examination. A computer program connected to the gamma camera was utilized to calculate the portal fraction of the total hepatic blood flow. In this work 93% of patients with abnormal portal fraction showed a colloid shift [P <0.001]. In 12 out of 15 cases [80%], portal fraction was abnormal and endoscopy revealed the presence of varices. Also, 97% of endoscopically evident varices had colloid shift on the scan. Portal vein diameter was normal in 35.5% of patients with abnormal portal fraction and in 76.7% of patients with colloid shift. All patients with dilated portal vein showed a colloid shift on the scan. Results suggested that scintigraphic examination has to be considered as a valuable noninvasive technique for diagnosis of portal hypertension, especially in patients with normal portal vein diameter

This study was carried out in the wards of Obstetric Department and Nephrology Laboratory, Zagazig University Hospitals; A total of 60 women at term [30 normal "control" cases and 30 prolonged labour cases] were included in this work. Also. their neonatal acid-base balance was studied immediately after labour. The maternal blood samples were arterialized blood. They were taken in the vaginal delivery during late second stage and in the caesarean section cases before premedication und anaesthesia. The neonatal blood- samples were taken from the umbilical vein before the neonates had taken their breath thus imitating the intra-uterine condition changes in maternal and neonatal acid-base balance were noticed. Their changes were inclined towards acidosis in prolonged labour. Also there was a positive relationship between acid-base balance and Apgar scores. Prolonged labour cases with fetal heart rate below 120 beats per minute were associated with meconium stained amniotic fluids, poor Apgar scores and high mortality rate. This work suggests a new perinatal system to be applied in high risk pregnancies
