PG - 747-50 AB - The biodistribution of radiopharmaceuticals used in diagnostic imaging can be altered by a wide variety of factors. We studied the effect of murine B16F10 melanoma on the biodistribution in mice of 99mTechnetium-methylenediphosphonic acid (99mTc-MDP). Viable B16-F10 cell lines (1 x 10(5)) were inoculated subcutaneously in the dorsal region of 8-12 week-old male isogenic C57BV/6j mice. 14-16 days after inoculation, 99mTc-MDP was injected in the ocular plexus and after 0.5 hr the animals were rapidly sacrificed. The organs and tumor were isolated, the mass determined and the percentage per gram of injected activity (%ATI/g) calculated. The results shown that the %ATI/g:i/ has not been altered in inguinal lymph nodes, prostate, pancreas, testis, seminal vesicle, bladder, kidney, stomach, small intestine, spleen, thymus, heart, lung, brain and muscle; but ii/ significantly decreased in thyroid, bone, blood and liver. In conclusion, the B16F10 melanoma can alter the 99mTc-MDP uptakes in some organs.
