Animals: treated ip from the first to the ninth day with one injection per day, weighed from the first to the fifth (toxicity day). Accepted control value (medial survival) 9-14 days. Use 6 mice per test (one test equals one dose). A weight difference of more than 4 grams on the 5th day between the test cells and the controlled strains is the toxicity index. It is defined by
    T / C; 85% indicates toxicity, T / C 85-120%, indicates non-activity, T / C iKZ indicates activity,
