Effect of micronised fenofibrate on lipotoxicity and insulin sensitivity in spontaneously hypertensive rats treated with high-fat diet / 中国病理生理杂志

ABSTRACT

AIM:To observe the effect of micronised fenofibrate(lipanthyl)on lipotoxicity and insulin sensitivity(IS)in spontaneously hypertensive rats(SHR)with high-fat diet.METHODS:Twenty-seven SHR were randomly divided into three groups:normal chow group(n=9),high-fat diet group(n=9)and micronised fenofibrate treatment group(n=9).Micronised fenofibrate 100 mg?kg-1?d-1 was given orally to SHR,which diet on high-fat diet for three months.Intramuscular lipids were observed and lipids accumulation index(LAI)was calculated.Nonesterified fatty acid,glucose and insulin were determined in all rats.RESULTS:(1)Compared to SHR in normal chow diet group,body weight and the level of serum TG and TC increased significantly and the level of HDL-C decreased significantly in SHR fed with high-fat diet(P
