Background: The aim of this paper is to investigated the contribution of adipose tissue thought the adipokines and kidney failure (KF)

Methods: In male rats were fed with a standard lab diet (C) or a hypercaloric diet including 30% sucrose; obese group (Ob) and obese with kidney failure group (Ob/KF). We evaluated the changes of adipokines under conditions of obesity and KF, using 5/6 surgery to induce vascular injury. The anterior and media branches of the left kidney artery were tied together, leaving the posterior branch viable to enable the kidney to function. The right kidney was removed.

Results: A 90% survival rate of the animals was achieved due to special care taken. Kidney function progressively decreased after surgery. Compared with the control group, in the other two groups (Ob and Ob/KF) the level of leptin increased and that of adiponectin decreased (p < 0.01). Post-surgery increases were observed in blood pressure, lipids, creatinine and insulin (p < 0.01).

Conclusion: This model is proposed for the study pathophysiological mechanisms that lead to obesity and complications of kidney or cardiovascular function.
