Abstract : Enzyme assays using the gamma-glutamyl transferase method provided estimates of glutamine synthetase activity in rat brain homogenates subjected to a pure oxygen environment for over three hours. No loss of activity was detected versus controls subjected to air or pure nitrogen. This finding supports the lack of any connection between convulsions caused by in vivo inhibition of glutamine synthetase and convulsions caused by oxygen toxicity (oxygen at high pressure).
