[Decrease in the growth rate of Ehrlich's tumor and Pliss' lymphosarcoma with partial hepatectomy]

In experiments with transplantable tumors, partial hepatectomy, Rhodiola rosea extracts or their combination were shown to inhibit the rate of Ehrlich's tumor and Pliss' lymphosarcoma as well as dissemination of the latter. These effects are to a certain extent attributed to production of humoral factors by the liver inhibiting clonogenic activity of tumor cells in vivo and in vitro.
