In this study, the brachial plexus in the mole-rat was investigated. Six adult mole-rats were used and the brachial plexus of each was dissected. It was found that the brachial plexus in the mole-rat was formed by the rami ventralis of C5. A single root was formed from a major part of the ramus ventralis of C5 and through the joining of the whole of the ramus ventralis of C6, C7, C8 and T1. Thu...

Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very usefu...

Properties of adenosine triphosphatases (ATPases) in the choroid plexus of rabbit cerebral ventricles were investigated using tissue homogenates and subcellular fractions. Na,K-ATPase or HCO3-ATPase activity of choroid plexus was significantly lower than that of the brain or the kidney, respectively. Among the homogenates of choroid plexus from the lateral, third and fourth ventricles, there we...

BACKGROUND Posterior dislocation of the shoulder in brachial plexus birth palsy during the first year of life is rare but the incidence increases with age. The aim was to calculate the incidence of these lesions in children below one year of age. METHODS The incidence of brachial plexus birth lesion and occurrence of posterior shoulder dislocation was calculated based on a prospective follow ...

The choroid plexus, which is responsible for the maintenance of the biochemical milieu of the cerebrospinal fluid (CSF), avidly sequesters Pb. In order to test the hypothesis that chronic Pb exposure may impair choroid plexus function, male weanling Sprague-Dawley rats were exposed to Pb in drinking water at doses of 0, 50, or 250 micrograms Pb/ml (as Pb acetate) for 30, 60, or 90 days. The fun...

A morphological and quantitative study in the ileal and colonic myenteric and submucous plexuses of rats after BAC denervation was performed. Four groups were employed: SI--ileum control; CBI--denervated ileum; SC--colon control; and CBC--denervated colon. We used the Myosin-V immunohistochemistry technique to study the myenteric and submucous plexuses. In the submucous plexus of the ileum and ...

In the treatment of brachial plexus injury, nerves that are functionally less important are transferred onto the distal ends of damaged crucial nerves to help recover neuromuscular function in the target region. For example, intercostal nerves are transferred onto axillary nerves, and accessory nerves are transferred onto suprascapular nerves, the phrenic nerve is transferred onto the musculocu...

The percutaneus blockade of the celiac plexus is being performed nearly for a century. The aim of performing celiac plexus and splancnic nerve blocks was surgical anesthesia at the beginning. But because of the technical demands and variable results of celiac plexus and splanchnic nerve blocks as a surgical anesthetic, over time, these techniques were supplanted by spinal anesthesia and segment...

The surgical intervention is necessary in about 20% of all cases of the perinatal brachial plexus palsy. In this study the intra-surgical view and the applied microsurgical techniques were analysed. The clinical material consisted of 49 children with the obstetric brachial plexus palsy treated operatively, on which the following changes were found intra-surgically: compression of the brachial p...

The aim of the study was the microscopic evaluation of the human spermatic cord vessels, with special attention to the connection between the testicular artery and the veins of the pampiniform plexus. We used the corrosive cast method to visualise the angioarchitecture of the spermatic cord. Casts were evaluated using a scanning electron microscope. We observed that there is a narrow space (pre...
