The effect of a 90% small bowel resection on the exocrine pancreas was investigated over a three month period in adult Wistar rats. Control animals underwent a sham-resection consisting of a transection and reanastomosis of the small intestine. After jejunoileal resection, the wet weight of a gland increased significantly (52%) from the 15th day. The parallel increase in total protein, DNA and ...

Modulation of trigeminal spinal subnucleus caudalis neuronal activity following regeneration of transected inferior alveolar nerve in rats. To clarify the neuronal mechanisms of abnormal pain in the face innervated by the regenerated inferior alveolar nerve (IAN), nocifensive behavior, trigeminal ganglion neuronal labeling following Fluorogold (FG) injection into the mental skin, and trigeminal...

Descending activity from the brain shapes spinal cord reflex function throughout life, yet the mechanisms responsible for this spinal cord plasticity are poorly understood. Operant conditioning of the H-reflex, the electrical analogue of the spinal stretch reflex, is a simple model for investigating these mechanisms. An earlier study in the Sprague-Dawley rat showed that acquisition of an opera...

Spinal Wistar Hannover rats injected with olfactory ensheathing glia (OEG) have been shown to recover some bipedal stepping and climbing abilities. Given the intrinsic ability of the spinal cord to regain stepping with pharmacological agents or epidural stimulation after a complete mid-thoracic transection, we asked if functional recovery after OEG injections is due to changes in the caudal stu...

Objective: Low potential malignant diseases are more frequently discovered and laparoscopic central pancreatectomy (LCP) can be indicated. LCP usually preserving splenic vessels (LCP-PreSV), allows a low-risk of diabetes at the expense high morbidity represented mainly by postoperative pancreatic fistula (POPF) haemorrhage (PPH). We evaluated impact resection (LCP-ResSV) on short long-term comp...

Objective. To determine the optimal level of intersection pancreas based on features topography arterial vessels and pancreatic duct isthmus body pancreas. Methods. 44 complexes upper floor abdominal cavity were studied. An injection mass with subsequent fixation in a formalin solution was introduced into vessels. The tissue crossed over superior mesenteric vein along vertical lines drawn one, ...

Background The digital flexor tendon sheath (DFTS) is a common site of pathology in the UK equine population, often necessitating tenoscopic exploration. Common intrathecal pathologies may lead to fetlock canal constriction. palmar/plantar annular ligament (PAL) surgically transected relieve constriction or facilitate surgical access and instrumentation. Objectives objectives this study were (1...

pancreatic neuroendocrine tumors (pnet) are uncommon pancreatic neoplasms, accounting for 1-2% of all pancreatic tumors. however, they have a better prognosis and long-term survival compared to exocrine pancreatic cancer. pnets can be divided into functional or non-functional based upon whether or not they excrete active substances relevant to specific clinical syndromes. skeletal muscle metast...

background: axotomy causes sensory neuronal loss. reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. it is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. methods: animals (male wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...
