Intracisternally administered cholecystokinin produced long lasting hypothermia in mice, and the hypothermic effect was significantly antagonized by benzodiazepines like chlordiazepoxide and diazepam and by a benzodiazepine antagonist, Ro 15-1788, that were administered 1ntraperitonea Ily. Proglumide, a cholecystokinin antagonist, failed to prevent the hypothermia induced by cholecystokinin at a dose of 200 mg/kg. Benzodiazepines and Ro 15-1788 revealed a considerably strong hypothermic effect, but they still prevented the hypothermic effect of cholecystokinin. The precise mechanism of the antagonism between cholecystokinin and benzodiazepines remains unclear at present.
