Hayvan modelleri, insanlardaki etyolojik ve ilaca cevap bakımından
benzerlik gösteren duygulanım durumlarını (savunma davranışı gibi),
hayvanların davranışlarını ve fizyolojik değişiklikleri inceleyerek ifade etmeyi
sağlamaktadır. Laboratuar hayvanlarında, anksiyeteyi gösteren
davranış parametrelerini ölçmek için çeşitli testler geliştirilmiştir. Bu makalede
fare/sıçanlarda anksiyete ile ilişkili türe özgü, özgün davranışlar
anlatılacak, anksiyetenin tanımlanmasında yaygın olarak kullanılan ve
iyi tanımlanmış olan yükseltilmiş artı labirent veya aydınlık karanlık kutusu
gibi testlerden bahsedilecektir. Anksiyetede hayvan modellerinin
kullanımı yeni anksiyolitik ve anksiyojenik ilaçların araştırılmasında temel
oluşturmaktadır. Bu durum duygulanım bozukluklarına karşı etkili
ilaçların değerlendirilmesinde, hayvan modellerinin önemli ilerleme
sağlıyacağını göstermektedir. Makalemizde, bu modellerde kullanılan
çeşitli ilaç uygulamaları ile ilgili önemli bulgular da sunulacaktır.
Overview of the some current experimental animal models for testing anxiety
Animal models attempt to represent human behaviors and
physiological changes, in order to study the etiology and the effects of
interventions on these behaviors. Various test paradigms have been
developed to assess behavioral parameters indicating the anxiety in
laboratory animals. In this article, species-specific behavioral
expressions related to anxiety in rodents will be described. Some
well-established and widely available tests for anxiety, such as the
elevated plus maze or the dark/light box, will be investigated. The use
of animal models of anxiety has been fundamental in the search for
new anxiolytic and anxiogenic compounds. This represents a
significant improvement over other animal models for evaluating
drugs effective against emotional disorders. Another goal of this
paper is to review the data about animal models in various drug
applications.
