Abstract
Diabetes mellitus is a growing health problem all over the world because of complications and cost of treatment. In diabetic studies animal models are frequently used, as in other scientific studies. As in other scientific studies, diverse animal models are used in diabetes research. Increasingly experimental animal models have been developed to elucidate the underlying mechanisms of type 1 and type 2 diabetes pathologies, to prevent complications, and to develop new drug trials. Many animal species can be modeled with chemical drugs (streptozotocin and alloxane), surgically removed pancreas (pancreatectomy), and genetic methods to model type 1 and type 2 diabetes. In this review, animal models of diabetes and information on the latest developments about prevention have been focused.

Abstract
Diabetes mellitus günümüzde sıklığı, sebep olduğu komplikasyonlar ve tedavi maliyeti nedeniyle tüm dünyada önemi gittikçe artan bir sağlık problemi olarak karşımıza çıkmaktadır. Diğer bilimsel çalışmalarda olduğu gibi diyabet araştırmalarında da çeşitli hayvan modelleri kullanılmaktadır. Tip 1 ve tip 2 diabet patolojisinin altında yatan mekanizmaları ortaya çıkarmak, komplikasyonlarını önlemek ve yeni ilaç denemeleri için deneysel hayvan modelleri geliştirilmektedir. Birçok hayvan türünde kimyasal bazı ilaçlarla (streptozotosin ve alloksan), cerrahi olarak pankreasın çıkarılmasıyla (pankreatektomi) ve genetik yöntemlerle tip 1 ve tip 2 diyabet modeli oluşturulabilmektedir. Bu derlemede, diyabetik hayvan modelleri ve önemi hakkında son gelişmeler ışığında bilgiler verilmiştir.
