    Abstract:
    Subrenal capsule assay(SRC assay) has been reported to be an effective and rapid method for predicting the tumor sensitivity of individual patients to anti-cancer agents. In order to establish a more objective method of determining sensitivity in SRC assay the DNA content was measured by the schmidt-Thannhauser-Schneider method and the protein content was estimated using Bio-Rad protein assay, after removal of a tumor implanted in the subrenal capsular space of ddY mice. Percentage inhibition of DNA/protein had a high correlation with that of relative increase of tumor weight, although three groups treated with mitomycin-C, 5-fluorouracil and cyclophosphamide indicated different values of tumor sensitivity. From these results, the percentage inhibition of DNA/protein seems to be more objective than microscopic measurement for predicting tumor sensitivity.
