STUDY OF MORPHOLOGICAL CHANGES OF HEART IN VIRAL MYOCARDITIS CAUSED BY REPETITIVE INFECTION OF CVB3m

Objective To investigate the morphological changes of heart in viral myocarditis caused by repetitive infection of CVB3m. Methods 4-week-old mice were infected four times intraperitoneally with a timedependent dose and killed at the 10th, 30th and 60th day after the final infection respectively, then we examined the heart changes and collagen hyperplasia by HE, VG stain and 1HC. Results Heart damage appeared very serious at the tenth day, even there were small necrotic foci at the day of 30th, but we could not see any injury of heart 2 months later after final infection. Collagen turned up at the tenth day and there was much more collagen in heart and increased PCVA, CVF index at the sixtieth day. The 1HC of collagen demonstrated the collagen I hyperplasia was much obvious compared to collagen Ⅲ. Conclusion It strongly indicated that repetitive infection of CVB3m could lead to heart fibrosis and ventricular remodeling, which resulted in decreased systolic and diastolic function of heart.
