Embodiment 1

[0056] Example 1, cycloastragenol (CAG) on isoproterenol (ISO) induced mouse myocardial fibrosis protective experiment

[0057] Experimental mice: 10-week-old male BALB / c mice (average body weight 20 g).

[0058] 1. The experimental mice were randomly divided into the following 4 groups (5 in each group) for the experiment:

[0059] Normal control group: for 7 consecutive days, 0.9% (mass percentage) NaCl aqueous solution was used for gavage (200 μL / rat) every day.

[0060] Model group: for 7 consecutive days, subcutaneously inject isoproterenol ISO (5 mg / kg) to the back of the experimental mice every day, and at the same time use 0.9% (mass percentage) NaCl aqueous solution to gavage (200 μ L / mouse) every day.

[0061] Cycloastragenol low-dose group: for 7 consecutive days, subcutaneously inject isoproterenol ISO (5 mg / kg) to the back of the experimental mice every day, and adopt cycloastragenol (CAG) for gavage every day simultaneously, and cycloastragenol is dissolved in 0...

Abstract

The invention discloses an application of cycloastragenol in prevention and treatment of myocardial fibrosis. The cycloastragenol is applied to one of the following steps (a1) and (a2): (a1) preparinga product for preventing and/or treating myocardial fibrosis; (a2) preventing and/or treating myocardial fibrosis. The cycloastragenol can effectively inhibit a myocardial collagen volume fraction increase, an expression level increase of myocardial fibrosis marker genes in myocardial tissues, an mRNA expression level increase of ANF genes in myocardial tissues, an expression level increase of related inflammatory cytokine genes and the degree of infiltration of inflammatory cells in the heart of the body due to the myocardial fibrosis, and the symptom of irritating dry cough does not occur in experiments of the cycloastragenol. In summary, the cycloastragenol plays an important role in preventing and treating the myocardial fibrosis, and has a great application prospect in the preventionand treatment of the myocardial fibrosis.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to the application of cycloastragenol in preventing and treating myocardial fibrosis. Background technique [0002] Myocardial fibrosis (MF) is caused by a variety of pathological factors and is characterized by excessive proliferation of interstitial fibroblasts in myocardial tissue, excessive deposition and abnormal distribution of collagen fibers, and a significant increase in collagen volume fraction. structure. Myocardial fibrosis is closely related to various cardiovascular diseases such as ischemic cardiomyopathy, hypertensive heart disease, dilated cardiomyopathy and hypertrophic cardiomyopathy. incentive. Fibrotic myocardial stiffness increases, compliance decreases, contractility decreases, and synchronization decreases, making the heart function gradually decline. Fibrosis provides an important structural basis for the occurrence of arrhythmia, and finally gradually turns int...
