  1. a. Body weight change (BWC) = (BW on sacrificing day)-(BW of experiment initiation); b. Tumor volume (TV) = (length × width2) × 0.532; c. Relative Tumor volume (RTV) = (TV on sacrificing day)/(TV on day 1 of injection); d. Inhibition rate on tumor growth (IR) = {1 - (mean RTV of the treatment group)/(mean RTV of the control group)} · 100.
