As a result, during the test period of 115 days, the adult dog 12 was not disordered and the liquid preparation of Example 1 was not toxic to the dog. In addition, there was no cancer metastasis in the dog. The liquid preparation having a concentration of 15% was kept administered to the dog further for 50 days, and the adult dog 12 did not change at all.
• Example 1 After this, the administration of the liquid preparation of Example 1 was stopped, and immediately the tumor of the adult dog 12 dramatically increased and the body weight thereof decreased by about 3 kg, and the dog weakened obviously.
• Hemangiosarcoma is an extremely malignant cancer that is insidious and rapidly spreads by metastasis to produce sarcoma everywhere in the body; and the period from the tumor detection of hemangiosarcoma to the death is generally 6 to 8 weeks (42 to 56 days). Accordingly, the prompt weakening of the dog immediately after the stopping of the administration thereto of the liquid preparation of Example 1 could fall within the range of the prediction. Against such an extremely malignant cancer, the administration of the liquid preparation of Example 1 exhibited the effect thereof of reducing the tumor and inhibiting the tumor from enlarging for 165 days, and in addition, the tumor of the dog did not spread by metastasis and the body condition of the dog was kept good. These confirm the great usefulness of the liquid preparation of Example 1 as an anticancer composition especially for hemangiosarcoma.
• Test Example 3 recommend a combination of medical therapy with the liquid preparation of Example 1 and surgical removal in clinical practice. This is because the administration of the liquid preparation of Example 1 was effective for preventing the tumor from enlarging and for preventing it from spreading by metastasis, and in addition, the body weight of the tested animal was kept as such and the body condition thereof was kept good, and there was found no problem in the blood test.

• An adult dog 14 (body weight, 30 ⁇ 5 kg; 6 to 7 years old; Maltese Herder) having mesenchymal tumor (soft tissue neoplasm) was first made to undergo a surgical operation to remove a part of the tumor; and after 6 days, the administration of the liquid preparation of Example 1 to the dug was started. This is because the tumor in the adult dog 14 suddenly increased. After the surgical removal operation and at the start of the liquid preparation administration, the adult dog 14 had symptoms of anemia as a result of the blood test thereof.
• Table 6 confirms that, during the administration period of the liquid preparation of Example 1, the adult dog 14 that had had symptoms of anemia owing to the surgical operation for partial tumor removal recovered in point of all the data of erythrocyte, hemoglobin and hematocrit thereof, and that the adult dog 14 recovered from the sign of anemia. Accordingly, the results in Test Example 5 recommend a combination of medical therapy with the liquid preparation of Example 1 and surgical removal in clinical practice. This is because the administration of the liquid preparation of Example 1 to the anemic dog after surgical operation was effective for preventing the tumor still remaining after the removal operation from again enlarging and for further reducing the size of the remaining tumor, and in addition, the liquid preparation was effective for recovering the body condition of the dog from the sign of anemia.
