OBJECTIVE To determine the Sunderland classification of a bipolar electrocautery injury. METHODS Twenty-two rats received crush (a reproducible Sunderland second-degree injury) or bipolar electrocautery injury and were evaluated for functional, histomorphometric, and immunohistochemical recovery at 21 or 42 days. Animal experiments were performed between July 3 and December 12, 2007. Axonal r...
On-site mortality in crush syndrome remains high due to lack of effective drugs based on definite diagnosis. Anisodamine (Ani) is widely used in China for treatment of shock, and activation of α7 nicotinic acetylcholine receptor (α7nAChR) mediates such antishock effect. The present work was designed to test whether activation of α7nAChR with Ani decreased mortality in crush syndrome shortly aft...
National Institute for Occupational Safety and Health (NIOSH) researchers continue to study the potential for lithium and lithium-ion battery thermal runaway from an internal short circuit in equipment for use in underground coal mines. Researchers conducted cell crush tests using a plastic wedge within a 20-L explosion-containment chamber filled with 6.5% CH4-air to simulate the mining hazard....
Early inflammatory events may inhibit functional recovery after injury in both the peripheral and central nervous systems. We investigated the role of the inflammatory tumor necrosis factor/nuclear factor-kappaB (NF-kappaB) axis on events subsequent to sciatic nerve crush injury in adult rats. Electrophoretic mobility shift assays revealed that within 6 hours after crush, NF-kappaB DNA-binding ...
An increasing weight of evidence implicates early inflammatory events as inhibitors of functional recovery in both peripheral and central neuropathologies. In this study, we investigated the role of the inflammatory TNF-α/NF-κB axis on events subsequent to sciatic nerve crush injury in rats. Electrophoretic mobility shift assays (EMSA) revealed that within 6 hours post-crush NF-κB DNA binding a...
Crush injury is a recognised cause of acute renal failure, histologically giving characteristic myoglobin casts in biopsy specimens. A similar syndrome can be precipitated by muscle damage associated with barbiturate overdose1 and carbon monoxide poisoning.2 We report a case of acute renal failure in which the renal biopsy specimen showed a typical "crush injury" appearance due to severe acute ...
This study examines the ability of osteoprotegerin (OPG) to prevent the local bone resorption caused by sciatic nerve damage. Sixty-five 18-week-old male mice were assigned to one of six groups (n = 10-11/group). A baseline control group was sacrificed on day zero of the 10-day study. The remaining groups were placebo sham operated, placebo nerve crush (Plac NC) operated, 0.1 mg/kg/day OPG + ne...
Crush injuries can occur in large numbers following natural disasters or acts of war and terrorism. They can also occur sporadically after industrial accidents or following periods of unconsciousness from drug intoxication, anaesthesia, trauma or cerebral events. A common pathophysiological pathway has been elucidated over the last century describing traumatic rhabdomyolysis leading to myoglobi...
