Effect of Gl-BSP on splenic NK cytotoxic activity in S180-bearing mice (n = 5, $\overline{x}\pm \text{s}$).

Group	Dose (mg kg−1 × days)	Cytotoxicity (%)
Normal	–	35.6 ± 2.3
Model	–	8.3 ± 1.7###
CY	30 mg kg−1 × 7 (i.p, q. o. d)	0.6 ± 0.5***
Gl-BSP	50 mg kg−1 × 14	13.8 ± 1.0**
	100 mg kg−1 × 14	21.4 ± 2.9***
	200 mg kg−1 × 14	30.3 ± 1.1***

S180-bearing mice were administrated intragastrically with Gl-BPS (50, 100, or 200 mg kg⁻¹) or physiological saline for 14 days, and the splenic NK cytotoxic activity of mice was examined in a 4-h ⁵¹Cr assay. Target cell: YAC-1. Effector: target cell = 40:1; ^###P < 0.001 model group vs. normal group; **P < 0.01, ***P < 0.001 vs. model group.
