ABSTRACT
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.

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.

El inhibidor de la monoaminooxidasa isatin y el ligando de B-receptores colecistokinina-4 juegan un papel significativo en la supresión e inducción de los estados de ansiedad y depresión. Nosotros hemos inducido la formación de auto-anticuerpos contra estas sustancias mediante la inmunización de ratas blancas. El resultado fue la estimulación prolongada (más de 2 meses) de conducta depresiva y de ansiedad tras la inmunización con isatin y, por el contrario, la supresión de esta conducta después de la inmunización con colecistokinina. En el artículo se discute la posibilidad de la corrección de la conducta a largo plazo mediante la manipulación immunoquímica (AU)
