Distribution of 103Ru-chloride in tumor-bearing animals and the mechanism for accumulation in tumor and liver.
Tumor uptake rates of 103Ru-chloride were smaller than those for 67Ga-citrate. In three tumors and liver, 103Ru in the mitochondrial fraction containing lysosome increased with time after the administration of 103Ru-chloride. The concentration of 103Ru was more dominant in connective tissue (especially inflammatory tissue) than in viable tumor tissue or in necrotic tissue. Quite large amounts of 103Ru in the tumor and liver were bound to the acid mucopolysaccharide whose molecular masses exceeded 40,000. Behavior of this nuclide was essentially similar to that of 67Ga.
