Embodiment 1

[0023] Example 1 Select healthy male SD rats and randomly divide them into a model group and a blank control group. After one week of adaptive feeding, the rats in the model group were given high-fat feed freely, and at the same time, they were given 500 mg / kg / d sodium valproate normal saline solution by intragastric administration once a day, and were continuously fed for 8 weeks. . Rats in the blank control group were supplied with basal feed, and the same amount of blank normal saline was administered orally every day, once a day, and fed continuously for 8 weeks.

Embodiment 2

[0024] Example 2 Select healthy male SD rats (6-8 weeks old, body weight 180-220 grams) and randomly divide them into a model group and a blank control group. After one week of adaptive feeding, the rats in the model group were given high-fat feed freely, and at the same time, they were given 500 mg / kg / d sodium valproate normal saline solution by intragastric administration once a day, and were continuously fed for 8 weeks. . Rats in the blank control group were supplied with basal feed, and the same amount of blank normal saline was administered orally every day, once a day, and fed continuously for 8 weeks. During the modeling period, the compound high-fat feed fed to the model group rats consisted of the following formula: by mass percentage, 77.5% rat basal feed, 10% eggs, 10% coconut oil, 2% cholesterol, 0.5% bile salt; Based on the weight of rats, sodium valproate was 500 mg / kg / d. After 4 weeks of modeling, the rats developed symptoms of fatty liver, which continued to...

Abstract

The invention belongs to the field of animal experiment models, and discloses application of a composite high-fat forage to construct a non-alcoholic fatty liver disease rat model. The high-fat forage is composed of the following raw materials in percent by mass: 77.5% of a rat basic forage, 10% of egg, 10% of coconut oil, 2% of cholesterol, 0.5% of bile salt, and 500mg / kg / d of sodium valproate calculated according to the rat weight. After 8 weeks, rats all have typical non-alcoholic fatty live symptoms, and liver has a lot of fat accumulation along with inflammatory cell infiltration. The model establishing time is short, the success rate is high, and the composite high-fat forage is applicable to pathogenesis research induced by high-fat-diet combined medicines with liver-toxicity side effect, screening of related control measures and efficacy evaluation of treatment medicines.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a compound high-fat feed and its application in constructing an animal model of non-alcoholic fatty liver. The animal model can be used for the pathogenesis of non-alcoholic fatty liver induced by dietary compound drugs research and evaluation of preventive measures. Background technique [0002] With the improvement of people's living standards, changes in living habits and diet, and the wide application of imaging technologies such as ultrasound, the incidence of non-alcoholic fatty liver is increasing year by year, and it is showing a trend of younger age. It has become the three major liver diseases that endanger human health. one. The causes of non-alcoholic fatty liver are complex. High-sugar and high-fat diet-induced hyperlipidemia, obesity, and diabetes are considered to be the main risk factors for non-alcoholic fatty liver. [0003] With the advent of a large number ...
