Abstract

The invention relates to a preparation method of a hepatocyte apoptosis animal disease model by coinduction of D-galactosamine and lipopolysaccharide, in particular to a simple inducer formula and a simple operation process which can generate a hepatocyte apoptosis rate above 80% and reproduce a stable and reliable hepatocyte apoptosis animal model. The invention also relates to the application of the hepatocyte apoptosis animal model to the research on the pathogenesis of hepatitis and evaluation of novel anti-hepatitis medicaments.

Description

1. Technical field [0001] The invention relates to a preparation method of an animal disease model, in particular a simple inducer formula and a simple operation procedure, which can produce a liver cell apoptosis rate of more than 80%, and reproduce a stable and reliable liver cell apoptosis animal model And its application in the study of the pathogenesis of hepatitis and the evaluation of new anti-hepatitis drugs. 2. Background technology [0002] Hepatitis is a general term for inflammatory diseases of the liver. According to the etiology, it can be divided into viral, alcoholic, drug-induced and autoimmune hepatitis. Viral hepatitis is the most common, of which hepatitis B is the main one, and hepatitis C next. Hepatitis B is a very harmful worldwide epidemic infectious disease caused by hepatitis B virus (HBV). According to statistics, there are currently about 350 million HBV carriers in the world, and China is a high-infection area of ​​HBV. HBV carriers Patients a...
