Abstract:
Experimental myocardial lesions were produced in 79 adult rats by the application of electrocoagulator.The animals were killed at intervals from 12 hours to 60 days after the injury and the lesions were studied histologically and histochemically. Three stages can be distinguished during the process of wound-healing in the cardiac muscles. The first stage,12 hours to 2 days after injury.The retrogressive changes of in- flammation were apparent.Degeneration and necrosis of heart muscles were present in the area of the injury.Young connective tissue were formed. The second stage,4 to 13 days after injury.The newly formed cardiac muscle fibers retroceded.The scar was formed of ripe connective tissue. After injury,the change in glycogen content in the cardiac muscle fibers was more conspicuous of than that of the desoxyribose nucleic acid.
