近似人病理生理过程动物脂肪肝模型的综合建立方法

Objective To establish animal model of fatty liver similar with human pathophysiology used for the study of imaging quantitative diagnosis or verification of medicine curative effect. Methods Forty-five New Zealand white rabbits were used in this study. They were divided randomly into five groups : 10 rabbits in normal control group, 10 rabbits in experiment group 1,10 rabbits in experiment group 2,10 rabbits in experi-ment group 3,and remaining 5 rabbits were in a supplement group. Rabbits in normal control group were given free access to normal food and water for 9 weeks. Rabbits in the experimental groups were fed a high-fat and high-sucrose diet for 3,6,and 12 weeks,respectively. Rabbits in the supplement group were fed the same diet as the experimental groups. Liver specimen stained with HE and Sudan Ⅳ was examined histological. Results The success rate of hepatic steatotie models was 87 % (39 of 45 ) ;mortality was 13 % (6 of 45 ). There were 10 nor-mal livers, 10 mildly fatty livers, 9 moderately fatty livers, and 10 severely fatty livers in results (stained with HE), and the rate of conforming to Sudan Ⅳ was 75%. Conclusion The animal model of fatty liver with differ-ent severity can be established by being fed a high fat, high sucrose and alcohol diet.
