动物试验和临床试用都证实了口服卡介苗具有抗癌作用。在动物试验中,口服卡介苗可抑制同基因的肿瘤从盲肠原发病灶向肠系膜淋巴结转移。从获取接受治疗动物的肠系膜淋巴结细胞的化学荧光强度的测定来看,显示这些细胞的活性都有明显的升高。在临床试用中,发现口眼卡介苗治疗的胃癌和结肠癌病 Both animal experiments and clinical trials have confirmed that oral BCG has anti-cancer effects. In animal studies, oral BCG can inhibit the metastasis of isogenic tumors from the primary cecal lesion to the mesenteric lymph node. From the measurement of the chemiluminescence intensity of mesenteric lymph node cells obtained from the treated animals, it was shown that the activity of these cells was significantly increased. In clinical trials, patients with stomach and colon cancer who were treated with oral BCG were found
