大菱鲆Scophthalmus maximus（L.）（平均体重61 g），每千克体重精确注射1 g葡萄糖。血浆葡萄糖在注射后3 h出现峰值。此后，在24小时内观察到逐渐降低至基础水平。血浆三酰甘油浓度在第一个24小时内迅速下降，此后稳定值。血液红细胞压积值从注射前的20%降至注射后72 h的16%。肝糖原浓度在前12 h内从8 g 100 g（-1）（w.w）开始下降至5 g 100 g（-1）（w.w），此后稳定，而肌糖原浓度在前12 h内增加，此后逐渐下降，直至72 h。该反应最可能是由处理后的继发性变化以及对葡萄糖负荷的直接反应引起的。因此，大菱鲆能够在24小时内有效地恢复碳水化合物代谢的改变。
Eighty turbot, Scophthalmus maximus (L.), (average weight 61 g) were injected intraperitoneally with exactly 1 g glucose per kg body weight. There was a peak in plasma glucose 3 h post injection. Thereafter a gradual decrease to basal levels was seen within 24 h. Plasma triacylglycerol concentrations showed a rapid decline during the first 24 h, and thereafter stable values. Blood haematocrit values decreased from 20% before injection to 16% 72 h after injection. Liver glycogen concentrations showed an initial decrease from 8 to 5 g 100 g(-1) (w.w) during the first 12 h, and thereafter stable values, while muscle glycogen concentrations increased during the first 12 h, and thereafter showed a gradual decline until 72 h. This response was most probably caused by secondary changes upon handling in combination with the direct response to a glucose load. Thus turbot was able to restore alterations in carbohydrate metabolism efficiently within 24 h.
