Effect of extracts of trichosanthes root tubers on HepA-H cells and HeLa cells.

AIM: To investigate the cytotoxic activity of extracts of trichosanthes root tubers (EOT) on HepA-H cells and HeLa cells compared with trichosanthin (TCS), and to explore the possible mechanism of growth inhibitory effect of EOT on HeLa cells. METHODS: Tumor cells were cultured in vitro, and then microculture tetrzoalium assay (MTT) was used to investigate drugs' cytotoxic activity. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to observe ultrastructural changes of cells, and electrophoresis was performed to detect changes of biochemical characteristics of intercellular DNA. RESULTS: TCS and EOT had no obvious effects on HepA-H cells (P>0.05), but had remarkable effects on HeLa cells in a time and dose dependent manner (r>0.864, P
