糖尿病的患病率呈逐年升高的趋势 ,其发病机制也正在得到阐明 ,认为它与多种致病基因和环境因素 (生活习惯、年龄、应激反应 )的交互作用有关。但从患者中得到的研究材料受到诸多因素的制约 ,需要利用糖尿病动物模型来进行一些基础性研究。在此之前曾通过各种手段 (药物投入、 The prevalence of diabetes is increasing year by year. The pathogenesis of diabetes is also being clarified, which is related to the interaction between various pathogenic genes and environmental factors (lifestyle, age, stress response). However, the research material obtained from patients is constrained by many factors that require the use of diabetic animal models for some basic research. Prior to this has been through various means (drug input,
