| Abstract | ||||
| Cytop < /strong>hotometric measurements of DNA - content were performed in the left atrium of normal and at 2 - 3 months after experimental, left myocardial infarction in adult albino rats. In normal rats 94% of the nuclei contain the dip < /strong>loid amount of deoxyribonucleic acid (2N) and 6% of tetraploid nuclei ( 4 N). After 2-3 months of the exp < /strong>erimental infarction, the prop < /strong>ortion of the polyploid nuc lei were increased up to 74%, while the diploid amount was decreased to reach 26%. The cell nuclei of muscle fibers with tetraploid ( 4 N ) were increased up to 44.5%, octoploid ( 8N) DNA - content reach to 24.1% and with 16 ploid (16 N) about 5.4%. | ||||
