HYPOTHESIS Blood loss in hepatic resection is an important determinant of operative outcome. OBJECTIVE To clarify whether reducing the tidal volume would be effective in decreasing blood loss during liver transection. DESIGN Randomized controlled trial. SETTING University hospital. PATIENTS Eighty patients scheduled to undergo hepatic resection were randomly assigned to receive liver tr...

BACKGROUND After portal vein ligation of 1 side of the liver, the other side regenerates at a slow rate. This slow growth may be accelerated to rapid growth by adding a transection between the 2 sides, i.e., performing portal vein ligation and parenchymal transection. We found that in patients undergoing portal vein ligation and parenchymal transection, portal vein hyperflow in the regenerating...

The intact sciatic nerve contains levels of nerve growth factor (NGF) that are comparable to those of densely innervated peripheral target tissues of NGF-responsive (sympathetic and sensory) neurons. There, the high NGF levels are reflected by correspondingly high mRNANGF levels. In the intact sciatic nerve, mRNANGF levels were very low, thus indicating that the contribution of locally synthesi...

19 Sacrocaudal motoneuron gene expression is altered following a spinal transection. Of interest 20 here is the regulation of serotonin (5-HT) receptors, mGluR1 and KCC2 which mediate 21 motoneuron excitability, locomotor recovery and spasticity post-transection. The examination of 22 these genes in lumbar motoneurons post-transection has not been studied, which is necessary for 23 developing p...

We have investigated the effects of ascending inhibitory pathways on two centrally generated rhythmic motor patterns in a simple vertebrate model, the young Xenopus tadpole. Tadpoles swim when touched, but when grasped respond with slower, stronger struggling movements during which the longitudinal pattern of motor activity is reversed. Surgical spinal cord transection to remove all ascending c...

BACKGROUND There is limited appreciation of the risks and benefits of the few salvage treatment options available for inadequate motor function following incomplete spontaneous recovery or surgical repair of major peripheral nerve injuries. The lack of a reliable and economical animal model has hindered laboratory investigation into this difficult clinical problem. We propose a straightforward ...

In an embryonic chicken, transection of the thoracic spinal cord prior to embryonic day (E) 13 (of the 21-day developmental period) results in complete neuroanatomical repair and functional locomotor recovery. Conversely, repair rapidly diminishes following a transection on E13-E14 and is nonexistent after an E15 transection. The myelination of fiber tracts within the spinal cord also begins on...

We measured renal, splenogastric, and lumbar multiunit sympathetic activities in chloralose-anesthetized, paralyzed, and artificially respired Sprague-Dawley rats. Acute spinal transection reduced arterial pressure and lumbar sympathetic activity. However, renal and splenogastric activities were doubled after transection. We conclude that spinal systems exist in the rat that are capable of main...

In anatomical resection of the liver, transection of the hepatic vein or Glisson's pedicle is necessary. We examined the surgical records and outcome of 25 patients who underwent hepatectomy. An endovascular stapler with 35 and 60 mm staples was used for transection of the hepatic vein or Glisson's pedicle, and hepatic parenchyma including vessels. Surgery included also left lateral sectorectom...

Background: Preoperative hemorrhage and postoperative bile leakage are important complications of hepatectomy. various methods to reduce intraoperative bleeding during liver transection have been reported. We designed a randomized clinical trial compare crush clamp method ultrasound dissection in transection. Method: Twenty patient experienced hepatectomy with the method. The ultrasonic group c...
