魔芋对大鼠体重及某些生化指标的影响

The Effects of Konjac Mannan （KM） on Body Weight and Some Biochemical Parameters in Rats

本文将39只Wister大鼠按体重随机分成4组：安静（对照）组，运动（对照）组，10％魔芋（运动）组和15％魔芋（运动）组。观察魔芋减体重的效果及对大鼠机能状况的影响．结果如下：1．10％魔芋组13天减体重7．50％；15％魔芋组5是减体重7．66％，13天达9．38％，且15％魔芋组使大鼠维持体重下降趋势达5天。2．魔芋组的摄食量明显低于对照组，且实验的前5天15％魔芋组的摄食量又明显低于10%魔芋组。3．魔芋减体重对大鼠血红蛋白含量无明显不良影响。4．魔芋饲料可使大鼠安静血糖明显下降至正常水平。5．魔芋饲料可使大鼠安静血清胆固醇和甘油三酯含量明显下降至正常水平。6．魔芋饲料对大鼠15分钟跑台负荷无明显影响。

39 Wister rats were randomly divided into 4 groups of sedentary （control）, exercise （ control）, 1 0% KM （exercise）, and 1 5 % KM （exercise） to observe the effects of KM on their body weight and functional conditions. The results showed that： 1. in 10% KM group, body weight of rats were decreased 7. 50% within 13 days; but in 15% KM group, the record was 7.66% within the first 5 days and 9. 33%within 13 days, and the tendency of body wight de- cline remained for 5 days; 2. food intake in both two KM groups wre significantly lower than that in the two control groups during all experiment, and in the first 5 days food intake of 15% KM was significantly lower than that in 10% KM group; 3. there was no adverse effects of KM on the hemoglobin of rats; 4. KM can make blood glucose in rat at rest decreased to normal levell 5. KM can make the level of blood cholesterol and triglycerides in rat at rest decreased to normal ; and 6. there was no evident effects of KM on the treadmill performance at 15m/min for 15 mins.
