Animal models for the study of alcoholism has been developed during the last years. These models contribute in revealing the mechanisms involved in this pathology. A synthesis of the main models used with rodents is presented along with studies that show the complex links between anxiety and alcoholism. The results indicate that alcohol acts as anxiolytic during early stages of consumption and as an anxiogenic agent when absent after chronic or acute doses, that the forced administration of ethanol provokes anxiolytic effects, and that the application of stressors alters the voluntary consumption of alcohol. There are few experiments that tested the relationship between alcoholism and frustration, a state considered equal to physical pain and to learned fear. The first results on the later subject obtained by the authors are described. Keys words: Alcohol, Anxiety, Frustration, Animal models.
Se han desarrollado modelos animales para el estudio del alcoholismo que permiten establecer los mecanismos involucrados en esta patología. Se presenta una síntesis de los principales modelos usados con roedores y las investigaciones que dan cuenta de las relaciones complejas que existen entre ansiedad y alcoholismo. Los resultados indican que el alcohol actúa como ansiolítico al comienzo del consumo y como ansiogénico con la privación del mismo después de su administración aguda o crónica; que la administración forzada de etanol provoca efectos ansiolíticos, y que la aplicación de estresores altera el consumo voluntario de alcohol. Hay escasos estudios que hayan evaluado las relaciones entre alcoholismo y frustración, un estado que se considera análogo al dolor físico o al miedo aprendido. Se describen los primeros resultados obtenidos por los autores sobre ese tema.
