[Distribution study using 57Co-, 51Cr-, 111In- and 99mTc-bleomycin in mice with a solid Ehrlich carcinoma]

From the comparative studies of 57Co-, 51Cr-, 111In- and 99mTc-Bleomycin using 282 solid Ehrlich-carcinoma-bearing mice, 57Co was found to be the most suitable bleomycin preparation for tumorscintigraphy. The results obtained by 111In-Bleomycin of linear tumor cell absorption indicates a possible use of 111In-Bleomycin as an agent for objective histological differentiation also in cells previously treated with therapeutic agents.
