| 摘 要： | 为探讨酸乳中EPS所具有的抗肿瘤等免疫功能，从酸乳中提取EPS，并对提取过程中脱除蛋白工艺进行了研究，结果表明采用酶解后Sevag除蛋白2次的方法效果最好。对EPS进行抗肿瘤(S-180)实验，抑瘤率在60％左右，说明酸乳中的EPS对肉瘤S-180具有较好的抑制作用，抑瘤最适剂量约为50mg/kg。

| Abstract: | Extracted EPS from yogurt to probe into the immune function of EPS such as anti-tumor and studied the technology of Protein-stripping during extraction. The result showed that Protein-stripping two times with Sevag after enzymolysis was the best. The inhibiting tumor rate of EPS was around 60% and the optimal dosage was about 50mg/kg. It proved that EPS in yogurt had the better inhibitory action for S-180. |
