| pubmed-article:2341219 | pubmed:abstractText | This study was undertaken to clarify the effects of topically injected chymopapain on the spinal cord and peripheral nerves in rabbits, and also the effect of ganglioside on sciatic nerves which had been damaged by chymopapain. There were no abnormal macroscopic or microscopic findings when chymopapain was injected around the sciatic nerve sheath or around the spinal dura mater, but when it was injected directly into the nerve sheath there was immediate paralysis and severe axonal necrosis; the Schwann sheath remained intact and there was haemorrhage. Injection into the dura resulted in massive haemorrhage, perivascular neutrophil infiltration and necrosis of grey matter. In those treated with ganglioside, regeneration of the damaged sciatic nerve was shorter than in those not so treated. | lld:pubmed |
