Studies on the umbilical affections in calves

A total number of 2102 calves was examined raging in age from one day to nine months. Thirteen cattle and buffalo farms in different areas of Upper Egypt were visited regularly. The common umbilical affections were studied in relation to housing and breeding systems, breed, age, sex and other accompanying diseases. The results showed that umbilical masses should not be dealt with a simple entity, but the different possible etiological factors should be considered. Moreover, surgical intervention proved to be the ensured way to deal with cases of umbilical masses individually

Studies on ruminant urolithiasis I-the effect of feeding fattening rations on bulls: a field study

The question of urolithiasis in fattening bulls constitutes one of problems that deserves serious considerations. If not diagnosed in a suitable time, thus promptly treated, animals harboring calculi may develop a fatal obstructive urolithiasis. Previous reports showed that death losses were over 3%. However, the incidence of calculi is usually allotted to metabolic disorders of which a imbalanced nutrition stands by. The present work was undertaken to investigate the calculi-provoking effect of commercially formulated rations commonly used in different fattening farms in Egypt. This was achieved by monitoring the serum biochemical changes occurring during the use of these rations throughout the different fattening stages

Doppler ultrasound study of flow velocity waveforms of the uterine and umbilical arteries in cases of placenta previa

Thirty patients having placenta previa and 20 normal pregnant women were investigated for the uterine and umbilical artery flow velocity waveforms during the third trimester of pregnancy. All c and idates were subjected to initial ultrasound examination, weekly Doppler ultrasound for uterine and umbilical artery S/D ratios, and weekly ultrasound for interval growth and BPS. Neonatal outcome was assessed by 1 and 5-minute Apgar scores, neonatal weight and placental weight. The study revealed no significant effect of placental location on uterine and umbilical artery S/D in cases of placenta previa and normal controls. However, cases of unilateral placenta previa had significantly higher uterine S/D ratio with compromised placental perfusion and low birth weight. Finally, the report recommended the use of uterine and umbilical artery Doppler studies complemented by standard surveillance tests as BPS to attain a more reliable assessment of fetal well-being

Some maternal effects of lumbar epidural analgesia during labour in pre-eclamptic patients

The effects of continuous epidural analgesia for labor were studied in 20 women with preeclampsia among those who admitted to El-Shatby University Maternity Hospital. Maternal hemodynamic, renal functions, arterial blood gas findings together with fetal cardiotochography were investigated. Significant reduction of pulse rate and mean blood pressure occurred 2 hours after epidural with insignificant effects on both CFR, RPF and U/PK; however, there was significant increase in the three parameters after delivery. Maternal blood gas analysis showed significant increase in PaO2 and pH, late patterns occurred in three subjects returned to normal beat to beat variation with head up position and oxygen administration. Continuous epidural analgesia was recommended as a useful method for labor in patients with preeclampsia

effect of hydration and epidural analgesia on the P-50 in pre-eclamptic patients

Twenty subjects suffering from preeclampsia were included in this study and divided into two groups: 11 cases in GI [mild] and 9 cases in GII [severe] PET. P-50 in both groups was shifted to the left. After hydration only, insignificant changes in P-50 were observed; but after epidural analgesia, a significant shift to the right was observed, this may be attributed to the significant improvement of pH. Significant increase in venous oxygen tension and venous oxygen saturation in both groups which may result from decreased oxygen needs to the paralyzed part and vasodilatation with increase blood flow to affected organs. An elevation in PH enhanced 2,3 PDG phosphatase. This led to an increased synthesis of 2,3-DPG and increased level of 2,3- DPG which might be the cause of increased P-50 after epidural analgesia
