Abstract

To study the effects of high-fat plus ethanol diet on myocardial ultrastructure in rats. 40 male SD rats in seventy-eight-week old were randomly divided into four groups: group A was control group, fed with common feedstuff; group B was high-fat diet group, freely foraging high-fat feedstuff; group C was ethanol group, the rats were intragastrically administered 60% ethanol solution twice a day by 1 ml/kg; group D was high-fat diet and ethanol group, the rats freely foraged high-fat feedstuff, and ethanol solution was intragastrically administered as before. After 12 weeks, blood samples were taken through jugular vein, the concentration of blood cholesterol (TG), triglycerides (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), and alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) were determined. The cardiac index was also determined for all groups and the cardiac morphous were observed by high resolution Doppler ultrasound, and myocardial ultrastructure was observed by transmission electron microscope. After experiment, TG levels of groups A, B, C, D were (1.07 +/- 0.21), (2.34 +/- 0.72), (1.33 +/- 0.42) and (1.75 +/...Continue Reading
