Abstract
An extract of mussels contaminated with Gonyaulax monilata was administered intragastrically to rats (1.5 or 2.0 ml extract/150 g body wt) 3 or 7 h before experiments. Intestinal disaccharidases were determined. Sucrase activity was changed in both mucosa and brush border after treatment. Maltase and lactase activities were affected only by the higher dosage.
摘要
在实验前3或7小时，将受纤细裸甲藻污染的贻贝提取物经胃内给予大鼠（1.5或2.0毫升提取物/150克体重）。测定肠道双糖酶。处理后，蔗糖酶活性在黏膜和刷状缘均发生变化。麦芽糖酶和乳糖酶活性仅受较高剂量的影响。
