Abstract
Objective To explore the age-specific changes in smooth muscle cell nuclei volume density of intima and media of
human coronary artery. Methods The initial segments of the left anterior descending artery were sectioned from 33 male cadavers
at 15 to 50 years by the paraffin-embedded method. The section preparations were stained by means of Verhoeff-VanGieson, and
measured with light microscopy and image analysis system. Result The smooth muscle cell nuclei volume densities do not
obviously change with age in the male coronary artery wall, but the changes in the intima and media are significant in the age groups
of over 31(P＜0.05) and between 41 and 50(P＜0.01). Conclusion The multiplication of smooth muscle cells in male
coronary artery wall is not clearly associated with age. Yet the cell muhiphcation at the ages of over 31 is greater in the intima than in the media.关键词
