研究资料表明 ,人体口腔唾液蔗糖酶是由口腔内多种产酸菌分泌的。其活性的高低与龋齿的发生和发展关系十分密切。近期又有报道 ,蔗糖酶活性与大肠肿瘤的恶变 ,与糖尿病及贲门的Ｂａｒｒｅｔｔ’ｓ腺癌的发生也有关。唾液蔗糖酶活性的测定也有报道 ,但动力学研究还很少见 ,其Ｋ Research data shows that human oral saliva sucrase is secreted by various acidogenic bacteria in the oral cavity. The level of activity is closely related to the occurrence and development of dental caries. Recently, it has also been reported that sucrase activity and the malignant transformation of colorectal tumors are also related to the occurrence of diabetes and cardiac Barrett’s adenocarcinoma. The determination of salivary sucrase activity has also been reported, but kinetic studies are still rare and its K
