ABSTRACT
Aim: To observe the influence of high fat-high sucrose diet and chronic stress on insulin resistance. Methods: Male rats were divided into four groups: control, high fat-high sucrose diet( HFSD), chronic stress( CS), high fat-high sucrose diet plus chronic stress( HFSD + CS). After feeding the animals for 10 weeks, fat, glucose and insulin concentrations in blood and PPAR-α mRNA expression in liver were examined, and glu-cose infusion rate was detected by a hyperinsulinemic euglycemic clamp experiment. Results: Insulin resistance was observed in all three treated groups, showing the highest in the HFSD + CS group. Dyslipidemia, hypergly-cosemia, hyperinsulinism and the decrease of PPAR-α mRNA expression in liver were also shown in all treated groups. There was an obvious interaction of insulin resistance, hyperglycosemia and high FFA between high fat-high sucrose diet and chronic stress. Conclusion: Combination of high fat-high sucrose diet and chronic stress could promote the development of insulin resistance, which is likely due to the high level of serum FFA.
