experiment example 3
[0041] Experimental example 3: Effect experiment on the range of myocardial infarction
[0042] Myocardial infarction area measurement method At the end of Experiment 1, cut out the heart, wash it with normal saline, remove blood stains, remove blood vessel fat and other non-myocardial tissue, and cut the ventricle into a 1cm-thick myocardium along the atrioventricular groove from the apex to the base of the heart in parallel. Slice and wash with saline. Myocardium slices were placed in 0.025% nitro blue tetrazolium (NBT) solution and incubated in a water bath at 37°C for 15 minutes for staining. The normal myocardium was stained blue, but the infarcted myocardium was not stained. Through the video recording device of the BI-2000 medical image analysis system, the myocardial slices of each group are input into the computer in the form of pictures, and then the area of the myocardial infarction and the whole myocardial area are determined and calculated by the software of t...
