the nervous system has an important and vital role in the human body, but unfortunately the repairment of damaged nervous tissue is very slowly. for a long time, the scientists have been involved in finding ways to speed up this process. radiation of low power he-ne laser has been suggested to as a way to improve this issue. in this study, 20 rats were divided randomly into control and case gro...

objective (s): scar formation in injured peripheral nerve bed causes several consequences which impede the process of nerve regeneration. several animal models are used for scar induction in preclinical studies which target prevention and/or suppression of perineural scar. this study evaluates the translational capacity of four of physical injury models to induce scar formation around the sciat...

background: initial studies have shown that low-energy ultrasound stimulates living tissue cells to reduce regeneration or speed up their recovery. the purpose of this study was to examine the effects of various ultrasound parameters on the speed of recovery in injured sciatic nerves. methods: nmri mice (n = 200) with injured left paw, caused by crushing their sciatic nerves, were randomly sele...

a 28-year-old man with neurofibromatosis type 1(nf1) presented with a tumor in the sciatic nerve and femoral nerve. the differential diagnosis of malignant peripheral nerve sheath tumor was based on clinical, radiological, and histological evidence. the tumor apparently originated in sciatic nerve at the posterior aspect of the left thigh. the lesion was resected totally without neural damage t...

Tensile stress and tensile strain directly affect the quality of nerve regeneration after bridging nerve defects by poly(lactic-co-glycolic acid) conduit transplantation and autogenous nerve grafting for sciatic nerve injury. This study collected the sciatic nerve from the gluteus maximus muscle from fresh human cadaver, and established 10-mm-long sciatic nerve injury models by removing the isc...

objective: to assess the effect of heparin binding neurotrophic factor (hbnf) on sciatic nerve regeneration in animal model of rat. methods: seventy-five male wistar rats were divided into five experimental groups randomly (each group containing 15 animals): sham operation group (sham), autograft group (auto), transected control (tc), chitosan conduit (chit) and heparin binding neurotrophic fac...

A persistent sciatic artery is a rare anomaly. On the other hand, a persistent sciatic vein is frequently associated with Klippel-Trenaunay syndrome. In a 71-year-old female with a complete-type persistent sciatic artery aneurysm, we performed aneurysmectomy and right femoropopliteal bypass surgery. The right popliteal vein drained into the femoral vein via a lower-type persistent sciatic vein ...
