Effect of PTL on growth of sarcoma 180 in mice

	Dose ※ (mg/kg)	Tumor weight (g)	Inhibitory rate *(%)
CTX	20.00	0.463 ± 0.180	68.3 ± 12.2
PTL	3.25	0.935 ± 0.160	36.2 ± 10.9
	2.30	0.995 ± 0.131	32.1 ± 8.9
	0.85	1.236 ± 0.132	15.6 ± 9.0
Negative control (0.9%NaCl)	-	1.465 ± 0.122	-

The anti-tumoral effect was determined by examining the tumor weight and calculating the inhibition rate as described below. The value of P (p<0.005) was calculated according to the tumor weight at every experiment group.

※Each dose was tested in 12 mice every other day for 10 days;

*Inhibitory rate = [(tumor weight of control mice-tumor weight of experimental mice)/tumor weight of control mice]x100%.
