【摘要】 以化学方法制备的蝇蛆脱乙酰几丁糖，按不同剂量喂饲试验动物雄性大鼠，检测其对试验动物的降血脂作用，结果表明：蝇蛆几丁糖能显著降低大鼠血清总胆固醇（ＴＣ）和甘油三酯（ＴＧ）水平。以蝇蛆几丁糖不同剂量喂饲昆明小鼠，检测其对小鼠抗突变和促进小肠运动作用的影响，结果表明：蝇蛆几丁糖可明显降低致突变物环磷酰胺对小鼠骨髓嗜多染红细胞的微核发生率和丝裂霉素Ｃ对小鼠睾丸染色体畸变发生率，对ＴＡ９８的抗突变试验结果为阳性；同时，对小鼠小肠推进百分数显著或极显著高于对照组，说明蝇蛆几丁糖具有抗突变作用和促进小肠运动作用。更多还原

【Abstract】 Kunming mice and male rats were fed with diffenent doses of chitin made by chemical means. The result shows that fly maggat chitin can reduce rats’serum TC and TG, and the chances of the occurance of marrow micronucleus and the distortion of testis chromosome on little mice. It can also accelerate the motion of small intestine of little mice.更多还原
