ABSTRACT
Comparative studies have been made on the retention of intravenously administered vanadium-48 and zinc-65 by blood, liver, femur, hair, and aorta in young and old rats of both sexes over a period of twenty days. Although it is extremely low, the vanadium-48 hair retention pattern generally reflects the accumulation of the radioisotope by the other tissues examined, except blood. Zinc-65 retention in hair continues to build up with the passage of time and appears to correlate only with the femur radioactivity. Age and sex are shown to be important variables in the retention of the two isotopes.
