Characterization of renal damage following perinatal gamma radiation in the beagle
Bilateral, whole-body /sup 60/Co ..gamma.. radiation (270 to 435 R) of beagles at 55 days in utero or 2 days of age resulted in a loss of kidney mass which was associated with thinning of the renal cortex and the presence of numerous immature glomeruli and nests of degenerating cells. Morphometric examination demonstrated a decrease in the density of mature and total glomeruli. These findings suggest that as a result of perinatal irradiation a significant reduction in structural and functional renal mass occurs which is due to a destruction of primitive metanephric tissue and an arrest in the further maturation of some nephrons. These events are associated with life-threatening secondary renal lesions which are characterized by progressive mesangial sclerosis of glomeruli and chronic renal failure.
