摘要

Hypertension (HT) was induced in Wistar rats aged 16 and 48 weeks by a deoxycortico-sterone acetate (DOCA)-salt procedure. Common carotid arteries were resected 16 weeks after, and their histological specimens were selectively stained for observations of collagen, elastin, and vascular smooth muscle (VSM) cells. Then, the fractions of collagen and elastin and their radial distributions, and the size and number of VSM cells were determined with an image analyzer. These results were compared with the results from age-matched, non-treated, normotensive (NT) animals and also with those from our previous biomechanical studies.
