??OBJECTIVE To study the antitumor effect of Pileostegia tomentella 95% alcohol extract (PTAE) on H₂₂ tumor-bearing mice and its possible mechanisms. METHODS Sixty mice were chosen and mouse models bearing H₂₂ solid tumor were established in fifty mice, and the others were as normal control. H₂₂ tumor-bearing mice were randomly divided into five groups:model control group, fluorouracil group(20 mg??kg^-1), PTAE high, middle and low-dose group(180, 90, 45 g??kg^-1 of crude drug, respectively). The mice in treatment groups were intragastric administration respectively, meanwhile, the mice in normal control and model groups were treated with the same volume of distilled water, once a day for ten days. The blood was collected from eyeball in all mice, and the serum were separated and detected by ELISA for IL-2 and TNF-??.Then the mice were put to death. Their tumors, thymuses and spleens were separated and weighted, and the tumor inhibitory rates, thymus and spleen indexes were calculated. The pathological change of tumor tissue was observed. RESULTS Compared with model control group, the tumor weights of PTAE high and middle-dose groups were significantly decreased (P??0.05, P??0.01), the tumor inhibitory rates were 37.44% and 38.46% respectively. The spleen index of PTAE middle-dose group was increased significantly (P??0.01). The level of IL-2 in serum of tumor-bearing mice in the PTAE high-dose group was increased significantly(P??0.05), and the level of TNF-?? in serum (P??0.01) could be increased significantly in the PATE high, middle and low-dose groups. CONCLUSION Pileostegia tomentella 95% alcohol extract has antitumor activity, its mechanism may be developed by immuno-regulation.

Antitumor effects of saponin extract from Patrinia villosa (Thunb.) Juss on mice bearing U14 cervical cancer

Saponin extracted from Patrinia villosa (Thunb.) Juss (SPVJ) is a Chinese medicine which is used widely by traditional medicine doctors. In this study, the antitumor effects and the possible mechanisms of SPVJ were investigated in mice bearing U14 cervical cancer. The results showed that SPVJ (50 mg/kg and 100 mg/kg) effectively reduced the weight of U14 cervical tumor (35.1% and 57.1%, respectively). Compared with the control group, SPVJ (100 mg/kg) significantly increased tumor cells in the G0/G1 phase (38.1% vs 68.5%), increased the number of cells in apoptosis (9.4% vs 28.9%) and G0/G1 phase and decreased the number of cells in S phase (41% vs 26.2%) and G2/M (20.9% vs 5.3%), inhibited proliferating cell nuclear antigen (PCNA) of tumor cell (80.6% vs 21.8%), decreased the expression of mutant p53 (66.4% vs 33.5%) and bcl-2 protein (78.2% vs 20.3%). The mechanism of the SPVJ antitumor effect might be associated with inhibition of tumor cells in G0/G1 phase, inducing apoptosis and inhibiting the expression of PCNA, mutant P53 and Bcl-2 protein.
