in healthy white rats [ 125i ] -desoxyuridine , [ 3h ] -thymidine , 2- [ 14c ] -uracyl , 8- [ 14c ] -adenine and [ 3h ) -uridine were used to demonstrate that the [ 125i ] -desoxyuridine metabolism in oral mucosa is analogous to that of thymidine and different from metabolic pathways of another nucleoside uridine and nitrogen purine and pyrimidine bases of adenine and uracyl .
