| Abstract: | Hailong S.acus Linnaeus was chosen as the experimental material in the experiments and changes of cell morphology, forming rate of clone and changes of division index were conducted to identify the inhibiting effects of Hailong extract on human tumor cell lines (GLT-82). Four days after medication, most of the cells changed their normal morphology of tumor cells and became round, broken and even broke into pieces. The inhibiting rates could reach 75.1% on the fourth day. The division index reduced strongly and the clone could not form or the forming rate was very low. With the extract concentration increasing and the time prolonging, the inhibiting effect increased. These results indicate that Hailong has striking anti-tumor effects and will have a perfect future in the fields of treatment and prevention of cancer. |
