Explants of tail fins from R. catesbeiana tadpoles undergo reepithelialization of their cut surfaces (healing) when cultured in vitro in Hanks' balanced salt solution at 22 degrees C. Healing is initiated early and closure of the wound is complete by 12 to 24 hours. Morphogenesis continues for several days as further reorganization and migration of(More)
A system for staging A. maculatum during growth and metamorphosis was devised, based on several parameters of body size; body length, tail length and tail width. Animals at various stages of metamorphosis were employed to study the relationship between specific biochemical and histological changes that occur in the tail of this urodele during metamorphosis.(More)
The rat sciatic nerve does not possess a high potential for regeneration through silastic tubes when the interstump nerve gap is greater than 10 mm. In this study, the effect of NGF treatment on regeneration of the rat sciatic nerve in 10- and 15-mm silastic chambers was compared. In addition, regeneration in 15-mm silastic chambers was compared to(More)
Previous reports suggest that nerve growth factor (NGF) enhanced nerve regeneration in rabbit facial nerves. We compared rabbit facial nerve regeneration in 10-mm silicone tubes prefilled with NGF or cytochrome C (Cyt C), bridging an 8-mm nerve gap, to regeneration of 8-mm autologous nerve grafts. Three weeks following implantation, NGF-treated regenerates(More)
