title: Morphological and biochemical changes in propylthiouracil-diet induced coronary atherosclerosis under a regression regimen.
abstract: Many of the morphologic and biochemical features of porcine coronary atherosclerosis produced by high cholesterol, high fat diet and propoylthiouracil returned to control values after cessation of the atherogenic regimen. These include disappearance of foam cells and a decrease in lipid content, DNA concentration, and DNA and protein synthesis. The morpholigic and biochemical features of te atherosclerotic lesions described herein were similar to those produced in swine and other species by a variety of inciting agents during both the progression and regression phase of the disease. These results indicate that the porcine propylthiouracil-diet model may be useful for the study of coronary lesions. Second, the similarities of response of arterial tissue in several experimental animals suggest the possibility that human coronary lesions by analogy may regress under therapeutic regimens.
