RESUMO
AIM To establish the hyperlipidemia and hyperlipidemic fatty liver animal model.METHODS 30 SD rats were randomized into control group (n=10)and model group(n=20).The rats of model group were fed with a standard diet and fat emulsion( 10 ml?kg -1);while the rats of control group were only fed with a standard diet.The serum TG,TC,ALT,AST,MDA,SOD and hepatic TG,TC,MDA,SOD were detected dynamically and with histologically.RESULTS The model group developed hyperlipidemia which TG and TC were elevated significantly after 1 week. 10 rats which were selected randomly in the model group were killed and the serum and liver were obtained after 2 weeks. The serum TG,TC,ALT and hepatic MDA of the model group rats were higher than the control's,while the hepatic SOD were lower. At the same time,the light degree hepatic steatosis of 2 rats were induced.The third week,both control group and model rats(n=10) were killed and the serum and the liver were obtained. Compared with the control group, the serum TG,TC,ALT,AST,MDA?SOD and hepatic TG,MDA of the model group rats were markedly higher, while the serum SOD and the hepatic SOD were significantly lower.The histopathology research showed hepatocellular macrovesicular steatosis and hepatitis in the model group. CONCLUSINOS The experimental animal model of hyperlipidemia and hyperlipidemic fatty liver in rats were successfully established for 1 week and 3 weeks fed with fat emulsion.
