An immunohistochemical study of the fibronectin in experimental viral myocarditis / 中国法医学杂志

ABSTRACT

For the purpose of establishment of a diagnostic method of mild viral myocarditis,an experimental mild viral myocarditis model was induced in Balb/c murine by coxsackie virus B 3.The cardiac tissue secfion were stained by LSAB-immunohistochemical method with anti fibronectin(Fn) antibody. The results demonstrated that the Fn deposition was found in the myocardium of mice with myocarditis and the mild degeneration of cardiomyocytes could be identified by Fn LSAB immunohistochemical staining.It is suggested that the Fn deposition in the myocardium tissue is one of the reliable marks of myocardium inflammation.
