Objective: To study the value of Fibronectin(Fn) immunohistochemical staining for diagnosing slight viral myocarditis.
Methods: The heart samples of human with myocarditis were studied by using LSAB immunohistochemical staining with anti-fibronectin antibody.
Results: Dense deposition was found in the myocardium of human with myocarditis. Some Fn-positive cardiomyocytes were observed.
Conclusion: Slight degeneration of cardiomyocytes could be identified by Fn-LSAB immunohistochemical staining and Fn-deposition is one of the reliable marks for inflammation in the myocardium.
