为了观察负荷剂量对葡萄糖耐量试验的影响,作者比较了110例健康成人于间隔3～9天服糖75 g和100 g后的血糖值,结果表明两种负荷剂量均显示葡萄糖耐量随年龄增长而递减。服糖后1小时,两种负荷剂量所测血糖均值,60岁以上组,100g略低(P<0.01);服糖后2小时时,各年龄组两种剂量差异均无显著性。因此,作者认为:75 g负荷剂量可以达到试验目的,病人容易耐受,节省费用,因而可以推广。 In order to observe the impact of loading dose on glucose tolerance test, the authors compared the blood glucose levels of 110 healthy adults at 75 g and 100 g at 3 to 9 days intervals. The results showed that both loading doses showed impaired glucose tolerance with age Decreasing. At 1 hour after oral administration, the average blood glucose level measured by the two loading doses was slightly lower than that at the age of 60 and 100g (P <0.01). There was no significant difference between the two doses at 2 hours after oral administration of sugar. Therefore, the authors believe that: 75 g load dose can reach the test purpose, the patient is easy to tolerate, save costs, which can be promoted.
