Objective To study the effect of black granule capsules(BGCs) on growth of transplanted mouse hepatocarcinoma cells, cell proliferation cycle and apoptosis.Methods KM mouse were subcutaneously inoculated with Hepatocarcinoma cells (H22) and randomly divided into the model control group, the positive control group, the low, medium and high does of BGC group after 24h. The positive control group received intraperitoneal injection with 30 mg/kg cyclophosphamide. Mice of BGC groups were intragastricaly with different dosage of BGC (400, 800, 1 600 mg/kg). The model control group received intragastricaly with normal saline. The drugs were administrated once a day for seven days. The tumor inhibition rate was calculated at 24 h after the last administration. Flow cytometry was used to detect changes of cell cycle and apoptosis in harvested H22 tumor cells.Results The group of high does showed significant inhibitory effect on the growth of transplanted H22 tumor cells withthe inhibitory rate 38.78% (male) and 43.57% (female). Compared with model control group, groups of different dosages decreased time of G0-G1 phase (58.06% ± 9.65%, 55.10% ± 5.89%, 61.36% ± 15.95%vs. 74.47% ± 2.63%), increased tiem of Sphase (33.96% ± 11.90%, 32.67% ± 4.04%, 33.89% ± 9.82%vs. 14.37% ± 4.92%), and increased the apoptosis rate (31.12% ± 1.85%, 31.89% ± 2.16%, 40.64% ± 0.55%vs.21.75% ± 2.64%).Conclusion BGC has antitumor effect on mouse hepatocarcinoma H22 tumor cells, and its mechanism was to regulate cell proliferation cycle and induce the apoptosis.
