Abstract
Sixteen rats were whole body irradiated with 250 Gy of /sup 60/Co ..gamma..-rays, killed at different intervals after exposure, and then observed by electron microscope. We found lysis of part of myofilaments in specimen obtained at 10 minutes after exposure, and resolution of Z-band at 30 minutes after exposure. These changes were more significant in sections at 12 hours postirradiation, but there also appeared cell regeneration at the same time. The vascular changes were more obvious with the endothelial cytoplasma projected in capillary lumen, nearly obstructing it. All of above described changes may be found in hematologic or intestinal forms of radiation sickness, but they must take place more late after exposure. In cardiovascular form, however, these changes were found as early as 10-30 minutes after exposure; this is a special feature helpful to diagnosis.
