本课题运用了组织化学、免疫细胞化学、电镜、图像分析及原位分子杂交等多种方法，对实验性肝癌、部分胃癌组织及体外生长肝癌CBRH7919细胞进行了各种参数指标的检测和实验观察，观察结果表明：肥大细胞（MC）对实验性肝癌及胃癌的发生和发展具有一定的抑制作用。该结论是通过
In this study, various parameters such as histochemistry, immunocytochemistry, electron microscopy, image analysis, and in situ molecular hybridization were used to detect and observe various parameters in experimental liver cancer, some gastric cancer tissues, and in vitro growth of liver cancer CBRH7919 cells. The observation results show that mast cells (MC) have a certain inhibitory effect on the occurrence and development of experimental liver cancer and gastric cancer. This conclusion is passed
