[Fibronectin immunohistochemical staining for diagnosing sudden death caused by viral myocarditis].

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.
