| Abstract: | Changes in blood glucose in response to glucagon and epinephrine administration, in rats bearing Yoshida solid sarcoma and Walker-256 carcinosarcoma have been studied, and in rats carrying Yoshida tumor which had received previously intraperitoneal glucose. The response to glucagon by tumor-bearing rats follows the control pattern but at a lower level of blood glucose. Rats which had received glucose before glucagon administration responded to this hormone as the control animals. These results indicate that glycogen metabolism in the host liver is not diturbed by the presence of the tumor. |
