用１０，５０，１５０及３００ｍｇ／ｋｇ岩藻糖胶给小鼠口服（灌胃），连续７ｄ，可使经四氧嘧啶诱发的高血糖小鼠血糖水平分别比阳性对照降低５４．２％，５７．１％，４３．３％及３６．９％。给已经四氧嘧啶形成的糖尿病小鼠注射１０ｍｇ／ｋｇ及５０ｍｇ／ｋｇ该糖胶后，其血糖水平分别为注射前的８０．４％和６０．６％，患病小鼠饮水量分别比阳性对照低约３６．２％及５０．６％，糖耐量明显改善，最佳作用时间在注射后４ｈ。 Oral administration of 10, 50, 150 and 300 mg / kg fucose gum to mice for 7 days resulted in a 54.2% decrease in blood glucose levels in alloxan-induced hyperglycemic mice compared with the positive control, 57.1%, 43.3% and 36.9% respectively. After injecting 10mg / kg and 50mg / kg glucagon into diabetic mice with alloxan, their blood glucose levels were 80.4% and 60.6% respectively before the injection, and the water intake in the diseased mice was higher than that in the positive Control low about 36.2% and 50.6%, glucose tolerance improved significantly, the best time in 4h after injection.
