Abstract
Experiments on outbred albino male rats showed that psychoemotional stress induced by intraperitoneal injection of cholecystokinin-4 (100 microg/kg) increased anxiety, impaired orientation and exploration activities in the elevated plus-maze and hole-board tests, and increased the level of depression of Porsolt test. Preliminary intranasal administration of glyprolines (15 min before cholecystokinin) in a dose of 3.7 micromol/kg prevented the development of stress-induced behavioral disturbances. Administration of peptides 30 min after cholecystokinin-4, i.e., to rats with developed behavioral disturbances, almost completely abolished these disturbances.
