Abstract : The toxin of major interest have been gyroxin, tetanus toxin, botulinum neurontoxin, the botulinum binary toxin, and ryanodine. Experiments have been conducted mainly on excised tissues, such as the phrenic nerve-hemidiaphragm preparation, and on cells in tissue culture, including neuroblastoma cells and adrenal medullary tumor cells. The major accomplishments have been: i.) the development of a rapid method for purifying gyroxin, ii.) characterization of the effects of gyroxin on central nervous system metabolism, iii.) a further description of the effects of ryanodine on divalent cation movement and oxygen utilization in muscle cells, iv.) an exhaustive evaluation of the effects of tetanus toxin on intracellular messenger systems, v.) a description of the pharmacological interaction between various drugs and botulinum neurotoxin, vi.) isolation and characterization of a human monoclonal antibody against tetanus toxin. Keywords: Neurophysiology, Central Nervous System. (KT/AW)
