This two-part investigation explored the parameters and mechanisms of: (1) injury to spinal cord (SC) neurons by nonfreezing low temperatures, and (2) hypothermic protection of SC neurons subjected to a defined, physical injury (dendrite transection). Conclusions from the studies of hypothermic injury were: (1) morphologic and ultrastructural signs of(More)
Cultured spinal neurons were subjected to dendrite amputation 100 microns from the perikaryon and treated with methylprednisolone (MP). Survival was significantly increased by 30 micrograms/ml MP but not by 10, 20 or 60 micrograms/ml. Survival was reduced by 100 micrograms/ml MP. These results suggest: (1) MP protects neurons subjected to physical trauma,(More)
The aim of this study was to test the hypothesis that ATP elevates cytosolic free Ca2+ levels ([Ca2+]i) in myenteric neurons expressing the Ca2+ binding protein, calbindin-D28. A laser microbeam marked the location of cultured neurons on coverslips and provided unequivocal relocation of ATP-responsive neurons after immunocytochemistry. All myenteric(More)
