Effect of isolation stress on glucose/lipid metabolism in Spontaneously Diabetic Torii (SDT) fatty rats.

Aim: The Spontaneously Diabetic Torii (SDT) fatty rat is a novel obese type 2 dia betic model, showing hyperphagia, obesity, and diabetes mellitus from a young age. In this study, we investigated the effects of isolation stress on pathophysiology in SDT fatty rats. Methods: SDT fatty rats (4 weeks old) were housed 3 per cage for 2 weeks and separated as males or females so as each gender will be placed in a separate cage to avoid mating. After acclimatization in 6 weeks of age, the rats were exposed to isolation stress (IS) (one rat per cage, using 5 animals in each sex). In the control group, each sex of experimental rats were housed
