Aging and arteriosclerosis.

Arteriosclerosis: facts and fancy.

Arterial vascular diseases comprise the leading cause of death in the industrialized world. Every physician learns about the pathology of these diseases in medical school. All pathologists evaluate arterial disease in surgical pathology and/or autopsy specimens. All clinicians encounter patients with clinical manifestations of these diseases. With such a common and clinically-important group of...

Aging and arteriosclerosis. I. Development of myointimal hyperplasia after endothelial injury

Old Fischer 344 rats are more susceptible to vascular lesions after arterial endothelial injury than are young animals. Thus, 20-26-mo-old Fischer 344 rats developed greater and more persistent intimal proliferative lesions than did 2-5-mo-old rats after aortic endothelial denudation. 3 d after deendothelialization, intimal thickness was increased two-fold in both old and young animals. However...

Experimental Arteriosclerosis

Arteriosclerotic lesions have been produced in monkeys (Macaca nemestrina) by selective removal of the vascular endothelium with an intra-arterial balloon catheter. Immediately after de-endothelialization a platelet layer covers the denuded area. This thrombus is gradually removed and by 7 days the vessel appears to be largely reendothelialized. Beginning at day 4, smooth muscle cells undergo m...

Vitamin B6 and arteriosclerosis.

In 1949, Rinehart and Greenberg reported that marked arteriosclerosis occurs in vitamin-B6-deficient monkeys. The present study investigates the relationship between vitamin B6 and arteriosclerosis and summarizes the results. I found that thrombogenesis, disorder of collagen metabolism and production of free radicals may be the processes that cause arteriosclerosis in human and experimental ani...
