Changes in response to metrazole during fever in juvenile rats; a new model for febrile convulsions?
Previous models for febrile convulsions have used environmentally induced hyperthermia as the stimulus to induce convulsions. Changes in response to metrazole during yeast-induced fever in juvenile rats are reported here. Animals were more susceptible to metrazole during the rising phase of fever but showed some resistance to its convulsant effects once the fever was established and following defervescence. It is suggested that this may form the basis of a physiologically more appropriate model for the study of the pathogenesis of febrile convulsions.
