| 摘 要： | 用糊精含量分别为５％、２５％、５０％的３种饲料饲养异育银鲫６周，再将禁食２４ｈ的鱼以每克体重灌注１．６７ｍｇ葡萄糖，同时胸腔注射胰岛素０．０１ＩＵ。实验结果表明，外源胰岛素具有显著的降血糖作用，且３组鱼血糖恢复到空腹水平后继续下降，以５０％糊精组降血糖作用最明显（Ｐ＜０．０５）。这说明异育银鲫对外源胰岛素敏感性强，而且饲料糖含量也影响其敏感性，造成这种敏感性差异的原因可能与胰岛素受体数量不同有关。

| Abstract: | The allogynogenetio crucian carp were fed with diets containing 5%, 25%, 50% dextrin respectively, for 6 weeks,and soon after a 24 h-fasted period, were injected with insulin 0.01 IU/g body weight and adminastrated with glucose 1.67 mg/g body weight.The exogenous insulin depressed blood glucose markedly and the blood glucose of the 3 groups kept on declining after back to the fasted level.The most obviouse effect occured in the 50% dextrin group.This indicates that allogynogenetio crucian carp are sensitive to exogenous insulin,and the sensitivity is influenced by the diet carbohydrate.The cause of the different sensitivity to the exogenous insulin may be contributed to the different numbers of insulin receptors. |
