This study was carried out to investigate the effects of dietary tocotrienol extracted from the rice bran on hematological and histological changes of the mouse. The mice were divided into seven groups (basal diet, cholesterol diet, tocopherol diet, and 4 different tocotrienol diets), and bred for a month. Tocotrienol diet was shown to have decreasing effects of serum triacylglycerol and LDL concentrations, whereas serum HDL concentrations were increased by tocotrienol diet. But serum cholesterol concentration was not statistically significant among the diet groups. Tocotrienol diet was shown to have decreasing effects of serum AST activities (P=0.0548) and LDH activities (P=0.0016), which are the standard indicators for liver damages or myocardial infarction. And tocotrienol diet has reduced the fat bodies accumulated in liver and heart caused from administration of rice bran oil. Also, the effects were shown as concentration-dependent manners. In conclusion, dietary tocotrienol extracted from rice bran has evident effects to protect or reduce lipid accumulation from blood, hepatocytes and heart muscles. It is also suggested as a good fortifying nutrition for the health and medical care.
