Comparison of PCNA positive cells ratio in tumor tissue of nude mice (, %).

Group	Dosage/mg·kg^−1	Number		PCNA positive cells ratio/%
		Begin	End
NM		12	12	95.81 ± 6.32
PCD	20	6	6	48.77 ± 11.56
TDH	100	6	6	53.02 ± 9.95

Note: data were expressed as mean ± standard error of mean. Data were analyzed by LSD test, versus Group NM. Results were considered significant at . Ten samples were observed in each group.
