Portal maemodynamic changes after eradication of esophageal varices by injection sclerotherapy

Sixteen patients presented with bleeding esophageal varices comprised the material of this study, their age ranged from 20-60 years, their liver biopsy showed mixed cirrhosis and bilharzial periportal fibrosis. Correlation between angiographic, laboratory, endoscopic and clinical findings were done. It is found that after a complete eradication of the gastroesophageal collaterals, there were angiographic evidence of obliteration of these collaterals in 68.7% of cases, and no development of new collaterals in any of them. Also, there were angiographic evidence of improvement in the degree of hepatic perfusion in 50% of cases which was confirmed by laboratory and clinical findings

analgesic and bone healing effects of transcutaneous electrical nerve stimulation

The effects of TENS on the relief of pain and bone healing was studied after the performance of experimental fractures in rats. With regards to these actions, TENS was compared with indomethacin as a commonly used drug for post-fracture pain relief.The right forelimb of 90 Albino rats was fractured and divided into three equal treatment groups.The first group received TENS, the second group received indomethacin while the rats in group 3 were left to heal spontaneously without any line of treatment. Pain threshold, radiological and histological healing scores were determined for each rat. TENS offers satisfactory analgesia equal to that of indomethacin, and at the same time enhances the process of bone healing in contrast to indomethacin which proved to retard the healing process. It is possible to conclude that TENS is a significant adjunct for simulataneous post fracture analgesia and enhancement of bone healing process and thereby actually shortens the phases of rehabilitation
