Abstract

The invention relates to a method for utilizing a gene chip to analyze lipopolysaccharide to stimulate variation of the expression profile of dairy cow mammary epithelial cells. The method comprises the following steps that 1, a dairy cow mammary epithelial cell inflammation model is built up; and 2, traditional Chinese medicine is tested by using the dairy cow mammary epithelial cell inflammationmodel.

Description

Technical field: [0001] The present invention relates to drug screening and its curative effect detection method, in particular to a method for detecting lipopolysaccharide-stimulated milk cow mammary gland epithelial cell expression profile changes with a gene chip, so as to detect whether lipopolysaccharide can trigger an inflammatory response, and as an inflammation model to test the effect of drugs on inflammation The role of the model and the mechanism of action. Background technique: [0002] Traditional Chinese medicine refers to the natural medicine and its processing substitutes that are guided by the theory of traditional Chinese medicine, have a unique theoretical system and application form, are used to prevent and treat diseases, and have rehabilitation and health care functions, mainly including herbal medicine, animal medicine, and mineral medicine. . [0003] The therapeutic effect of traditional Chinese medicine has long been determined based on the change ...
