Hyperbaric oxygen has been successfully used on treatment of acute ischemic injuries involving soft tissues and chronic injuries. In nerve crush injuries, the mechanisms involved are very similar to those found in ischemic injuries. Consequently, it is logical to hypothesize that hyperbaric oxygen should improve nerve repair, which is a critical step on functional recovery. In the present study...

Wallerian degeneration was produced in guinea pig sciatic nerves by a crush injury. At intervals of 2, 12, 24, 36, 48, 72, and 96 hours after the crush, the nerves were fixed in osmium tetroxide, and blocks from the distal, degenerating segment identified topographically prior to embedding in Araldite or Epon. Phase and electron microscopic study of serial cross- and longitudinal sections revea...

OBJECTIVE To establish a canine model of crush syndrome (CS). METHODS A total of 16 healthy adult female Beagle dogs were randomly divided into the control group (n=8) and the experimental group (n=8). The crush injury was created in the left hind leg of each dog in the experimental group. RESULTS The biochemical indexes in the experimental group changed significantly compared to the values...

The pudendal nerve innervates the external urethral sphincter and, when injured, can contribute to incontinence development. This experiment was designed to study the time course of functional changes in the urethra after pudendal nerve crush in rats. Leak-point pressure (LPP) was measured 2, 4, 7, or 14 days after bilateral pudendal nerve crush and was compared to that of a control group. LPP ...

Fatal crush conditions occur in crowds with tragic frequency. Event organizers and architects are often criticised for failing to consider the causes and implications of crush, but the reality is that the prediction and mitigation of such conditions offers a significant technical challenge. Full treatment of physical force within crowd simulations is precise but computationally expensive; the m...

There are a number of errors in the legends for Figs. 3, 4, and 5. The complete, correct legends for Figs. 3, 4, and 5 are: Figure 3.

to evaluate the effects of local administration of the fetal brain extract (fbe) on the crushed peripheral nerve, 15 male wistar rats were used. the right sciatic nerve of 10 rats was locally underwent the tense compression for 30 seconds and then randomly divided into experimental and control (sham) groups. the remained rats were considered as intact animals. treatment was commenced weekly, by...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...
