Time schedule and results for tumor volumes, survival periods, and rates of mice treated by Protocol number 2. (a) Protocols of Groups I, II, III, IV, V, and VI. (b) Tumor volumes on day 14 after re-challenge with B16F1 melanoma. All data are presented as mean ± standard deviation. Tumor volumes of Groups III and IV were found to be significantly reduced compared with those of the control group ( and , resp.) and Group VI ( and , resp.) by the Scheffé test. (c) Kaplan-Meier survival curves over a period of 60 days after re-challenge with B16F1. The survival rate of Group III was significantly prolonged compared with those of the control group ( ) and Group VI ( ). The survival rate of Group IV was significantly prolonged compared with that of the control group ( ), Group I ( ), Group II ( ), and Group VI ( ). One of the eight mice in Group III and three of the nine mice in Group IV were protected against re-challenge with B16F1 melanoma cells.
