Pathological Changes During Aging in, Barrier-Reared Fischer 344 Male Rats(1)	1977-05-17		.txt	text/plain	5903	385	54	The most severe pulmonary lesion was a mild focal atypical hyperplasia (Innes, Garner, & Stookey, 1967) which occurred in a few rats over 24 mo of age. Mild to moderate focal chronic interstitial myocarditis occurred frequently in rats less than 6 mo old and then decreased in incidence with increasing age. These two lesions were not always coincidental, but one or both appeared to be the predecessor of interstitial fibrosis, >vhich was first seen at 6 to 12 mo, and increased in incidence and degree with age. The most frequent lesion was bile duct hyperplasia, which increased in incidence and severity with age. A wide variety of pathology was found and tabulated, and many lesions were found to increase in severity and incidence with age.
