THE STUDY OF WOUND, BURN, AND FRACTURE HEALING IN THE ALBINO RAT AND MOUSE SUBJECTED TO CONTINUOUS IRRADIATIONS OF DIFFERENT INTENSITIES. Progress Report for June 1958-February 1959

Technical Report ·
OSTI ID:4187753
A chronic, low intensity Co/sup 60/ radiation facility is described which presents useful levels of radiation of 2, 5, 10, and 20 r per 23-hour day. This facility is being used to tnvestigate the influence of chronic radiation on the repair of incised, fractured tibia of albino rats during a twelve week period post fracture. There is some evidence that continuous exposure to 2, 5, and 10 r gamma radiation daily will affect normal deposition of bone mineral adversely in rats of 120 grams weight at the time of initiation of the experiment on animals which were maintained on a normal laboratory diet. Preliminary evidence indicates that incisure healing was affected adversely. Swiss aibino mice given radiation levels of 0, 2, 5, and 10 r daily were challenged by 90% burn trauma produced by 70 deg C water for 5 seconds immersion. Those animals receiving radiation showed a marked decrease in survtval for a four day period. Experiments underway on the influence of radiation on the hematology of the albino rat and on the survival of mice given pre- and post-natal low intensity chronic radiation are described. (auth)
