title: [A new method for evaluating acute toxicity intragastrically for classification of chemical substances].
abstract: The authors reviewed and presented a critical analysis of the literature on defining acute toxicity of chemicals after intragastrical administration by means of traditional methods and new ones such as fixed procedure, up-down, acute-toxic-classification. Rules and conditions for the evaluation of acute toxicity by means of these methods were presented as well as the way of defining a median, lethal dose administrated intragastrically for the purpose of chemical classification.
