[Tolerance dosage of normal tissues by radiotherapy combined with chemotherapy in the group of patients].

Normal tissues have sigmoid dose-response relationships. These relationships are reliably detectable in some clinical and many experimental situations through the aspect of radiobiology. By the way, when the group of patients are treated by radiotherapy combined with chemotherapy, the tolerance dosage of normal tissues in the group is not explained by biological aspect alone.

[A malignant mixed mesodermal tumor of the ovary].

We report a primary malignant mixed mesodermal tumor in the right ovary of 75-year-old woman. She was admitted to Kobe West Municipal Hospital because of an abdominal fullness and an upper abdominal pain. A laparotomy yielded yellowish-clear ascites (2,000 ml) a tumor located in the right ovary, an upper abdominal mass the size of a child's head between the stomach and the transverse colon, and disseminating small tumors of the peritoneum.
