The effect of cancer chemotherapy on lysosomal enzymic activities (acid phosphatase) of Ehrlich ascites carcinoma cells.
The distribution of acid phosphatase in Ehrlich ascites carcinoma cells was studied by histochemical techniques in mice treated with antitumoral agents (Tio-Tepa, Cosmegen). The results proved the accuracy of the histoenzymatic demonstration of APh activity for the study of early changes induced in Ehrlich ascites tumor by antitumoral drugs : these changes precede those revealed by routine histological methods and are related to the degree of sensitivity of the tumor to the drugs.
