Abstract

BACKGROUND
The PPAR alpha activator, Fenofibrate, is a pharmacological ligand, which induces beta-oxidation of long chain fatty acids in the mitochondria of hepatocytes. The beta-oxidation induced by exogenous PPAR alpha activators may be operated maximally when the sustained production of energy substrate in the liver is required by working muscles due to continued exercise. The aim of this study was to determine whether the combination therapy of exercise and Fenofibrate could synergistically reduce body adiposity in OLETF rats. METHODS: Twenty-eight male OLETF rats(13 wk old) were divided into four groups. The diet(n=7) and exercise groups(n=7) were fed with chow for 12 weeks. The Fenofibrate(n=7) and combined treatment(exercise and Fenofibrate) groups (n=7) were fed with Fenofibrate(32mg/kg/day) mixed chow for 12 weeks. The animals in the exercise and combined treatment groups were exercised by running on a treadmill for 12 weeks. At 24 weeks of age, all the rats were sacrificed, and examined by biochemical tests and had their adipose tissue weight measured. RESULTS: There were no significant changes in the retroperitoneal and subcutaneous fats between the diet and Fenofibrate groups, but there were between the diet and combined treatment groups(P<0.05). CONCLUSION: Exercise combined with Fenofibrate synergistically reduces body adiposity in OLETF rats
