| pubmed-article:528167 | pubmed:abstractText | Buffalo rats bearing thigh-implanted strain-7777 Morris hepatomas were used as a model for studying the effect of carrier material on the body distribution, tumor uptake, excretion, and tumor-to-background ratios of 67Ga and 54Mn. An effort was also made to observe the changes in 67Ga and 54Mn concentrations induced by carrier in viable tumor and skeletal muscle, relative to their interstitial fluid space. This value is referred to as the Tissue Distribution Index. Carrier manipulation resulted in striking changes in the distribution of the two ions from the carrier-free state. The data also indicated a difference in the pharmacodynamics of 67Ga and 54Mn in malignant and healthy tissues which could be of importance to nuclear medicine and oncology. | lld:pubmed |
