Embodiment 1

[0018] Example 1: AOAA effectively improves cardiac function after myocardial infarction

[0019] Cardiac function after myocardial infarction detected by echocardiography

[0020] Mice were anesthetized (the same method as before), placed in the left lateral position after depilation, placed the probe of the cardiac ultrasound diagnostic instrument on the anterior wall of the heart, and took a two-dimensional short-axis view of the left ventricle at the level of the papillary muscle, and recorded M-scan at the same time, for 3 consecutive Cardiac cycle measurement left ventricular ejection fraction (EF), fractional shortening (FS) and left ventricular end diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD).

[0021] Experimental results: Cardiac function was detected 28 days after myocardial infarction, and AOAA significantly improved cardiac function after myocardial infarction ( figure 1 ), ejection fraction ( figure 2 ) and short axis shortenin...

Embodiment 2

[0022] Example 2: AOAA effectively reduces the size of myocardial infarction

[0023] Masson staining: the mice were sacrificed 28 days after the operation, and the left ventricle tissue was taken for heart tissue staining to observe the therapeutic effect. Follow the routine Masson staining procedure, observe and take pictures under an ordinary light microscope. The image analysis software Image J was used to analyze the area of ​​each part, and the area of ​​myocardial infarction / heart area was calculated;

[0024] Experimental results: Masson staining was used to observe the infarct area of ​​each group 28 days after myocardial infarction ( Figure 4 & 5), AOAA was found to effectively reduce the size of myocardial infarction; *P < 0.05.

[0025] 【in conclusion】

[0026] The above results comprehensively prove that: AOAA can effectively improve the cardiac function after myocardial infarction, effectively reduce the size of myocardial infarction, so as to prevent or tre...

Abstract

The invention discloses application of aminooxyacetic acid (AOAA) in preparation of a drug or health-care product for preventing or treating myocardial infarction. The AOAA can improve cardiac functions after myocardial infarction and reduce myocardial infarction areas so as to prevent or treat the myocardial infarction.

Description

technical field [0001] The invention belongs to the pharmaceutical technology, and specifically relates to the application of aminooxyacetic acid in the preparation of medicines for preventing or treating acute myocardial infarction. Background technique [0002] Myocardial infarction is a cardiovascular disease that seriously endangers human health. With the continuous improvement of people's living standards in our country, the incidence of ischemic myocardial infarction is also increasing. An ischemic myocardial infarction can lead to scarring that can affect heart function. Most of the current drug or device treatments can only relieve the symptoms, but they cannot reverse the damage to the heart tissue. Although heart transplantation can completely improve the state of the heart, it is difficult to be widely used clinically due to factors such as scarcity of donor sources, immune rejection, and expensive treatment costs. At present, there are research reports on the a...
