RESUMO
The inhibitor of monoaminooxydase isatin and the ligand of B-receptors cholecystokinin-4 play a significant role in the suppression and induction of depressive and anxiety states. We induced the formation of auto-antibodies to these compounds against their conjugates with antigen-carrier by immunization of white rats. The result was long-term (more than 2 months) stimulation of depressive and anxiety behavior after immunization to isatin and, in contrast, the suppression of such behavior after immunization to cholecystokinin. The perspective of immunochemical approach to long-term correction of behavior is discussed.

Active immunization against cholecystokinin fragments 31-33 (CCK-3) and 30-33 (CCK-4) results in long-lasting changes of albino rats' behavior. CCK-3 and CCK-4 covalently linked to antigen-carrier evokes the suppression of the anxiety, decreases some signs of depression-like behavior and changes the level of bioamines and their catabolites in striatum at least for two months after immunization. These data can provide a perspective approach to the problem of long term correction of behavior.
