KSY did not cause toxic effects in immunocompetent tumor-bearing mice. The experimental protocol of bladder cancer cell (C3-B model in Figure 1) was performed. The body weights (a) and serum biochemical data (b) from various treatment groups were shown. n = 18-21 for each group. The serum data from healthy mice (n = 9-10) serves as reference values: AST: 30.9 ± 5.7 U/L; ALT: 34.1 ± 9.0 U/L; BUN: 21.2 ± 3.4 mg/dL; Creatinine: 0.2 ± 0.1 mg/dL.
