Abstract
The morphological changes of coronary and middle cerebral arteries in the cases of cerebral apoplexy and myocardial infarction were analyzed by morphometric techniques at light microscopic levels.
The ratio of circular extension length per thickness of media (MED) was increased with intimal thickness in coronary artery.
The increased MED accompanied with the increasing of medial smooth muscle cells in coronary arteries. The mesenchymal components composed of elastic and collagen fibers was differenced in the ratio between cerebral and coronary arteries.
The characteristics of atherosclerosis is circumference thickening instead of concentric thickening in coronary arteries compared with cerebral artery.
The atherosclerosis shows organ specificity in cerebral apoplexia and myocardial infarction and it suggests the difference in the angiospastic potentiality of each arteries.
