BACKGROUND The aim of this study was to determine the effects of amniotic membrane impregnated with betamethasone on regeneration of transected sciatic nerve injury in adult albino Wister rats. METHODS In this research, 42 male adult rats were divided into six equal groups. 1) Normal (intact) group: healthy rats without any injury; 2) CONTROL GROUP: sciatic nerve was cut and sutured; 3) Sham ...

BACKGROUND Muscle bellies of the hamstring muscles are intimately associated with the sciatic nerve, putting the sciatic nerve at risk of injury associated with proximal hamstring avulsion. There are few data informing the magnitude of this risk, identifying risk factors for neurologic injury, or determining neurologic outcomes in patients with distal sciatic symptoms after surgery. PURPOSE T...

1. Quiescent sciatic nerve of the frog discharges CO(2) at the average rate of 0.00876 mg. CO(2) per gram of nerve per minute. 2. Sciatic nerve steeped one minute in boiling water discharges CO(2) at first at a low rate and after an hour and a half not at all. 3. Degenerated sciatic nerve discharges CO(2) at a slightly higher rate than normal living nerve does. 4. Connective tissue from the fro...

Acetabular fracture is usually treated with osteosynthesis. However, in the case of an intra-articular fracture, osteosynthesis can result in arthropathy of the hip joint and poor long-term results, hence, total hip arthroplasty is required. However, in total hip arthroplasty for postoperative acetabular fracture, sciatic nerve palsy tends to develop more commonly than after primary total hip a...

Temporary paralysis is a rare manifestation of envenoming following the yellow Iranian scorpion, Odontobuthus doriae (O. doriae). Thus, to elucidate the underlying mechanism, we investigated the neurotoxic effect of venom in the sciatic nerve, the possible mechanism in a mice model. The neurotoxicity and temperature effects in the venom-induced neurotoxicity were examined using the mouse sciati...

After peripheral nerve injury, nociceptive afferents acquire an abnormal excitability to adrenergic agents, possibly due to an enhanced expression of α1-adrenoceptors (α1-ARs) on these nerve fibres. To investigate this in the present study, changes in α1-AR expression on nerve fibres in the skin and sciatic nerve trunk were assessed using immunohistochemistry in an animal model of neuropathic p...
