Nerve Suture and Nerve Degeneration

Laser vs. suture nerve anastomosis.

The repair of injured or transected nerves is frequently encountered in head and neck surgery. Recently, CO2 lasers with milliwatt capability and micrometer spot sizes have been developed that may be used in nerve anastomosis. A comparative study was performed between microsuture and CO2 laser repair of transected sciatic nerves in rats. Nerve regeneration was measured in terms of morphology, e...

Polyglycolic acid suture in peripheral nerve II: sutured sciatic nerve.

This experiment investigates the holding property of polyglycolic acid suture in repair of divided dog sciatic nerves and the influence of absorption of this synthetic material on regeneration. The conclusion is that PGA maintains its tensile strength sufficently long to allow both physical union and good regeneration of the divided nerve. The suture absorption does not influence regeneration.

Optic Nerve Degeneration and Ageing

Major pathological hallmarks of Alzheimer Disease are insoluble deposits of the short amyloid β-peptide (β-amyloid, Aβ), which is derived by sequential proteolytic cleavage from a large type I trans-membrane protein, the β-amyloid precursor protein (APP). APP is anterogradely transported by fast axonal transport in a distinct transport vesicle, but both the biochemical composition of such a ves...

Temperature Coefficient of Nerve Degeneration.

Proper microsurgical nerve suture may impede Wallerian degeneration of completely transected nerves. An electron microscopic study.

Electron microscopic findings on the nerve of the biventer cervicis muscle of the chick, which was completely transected and immediately after submitted to an adequate microsurgical nerve suture, confirmed our previous statement that proper microsurgical nerve suture may impede the Wallerian degeneration that normally occurs in the distal segment of a completely transected nerve.
